Title: Improvements in and relating to gumming devices
IPC: B65C11/04
Filed: 1950-04-10
Abstract: <PICT:0703615/III/1> <PICT:0703615/III/2> <PICT:0703615/III/3> A label-gumming device comprises a mechanism for causing gum to be applied to a label carrier which picks a label out of a stack arranged below the carrier and holds the label so that an operator can peel it off by hand.  A three-armed gum transferring device 14, Fig. 3, dips into a gum bath 12.  The labels 16 are in a stacker 18, which can be moved upwards by a rack 26 and pinion 28. A label carrier 32 is carried on a horizontal rod 36 supported by a pair of arms 38 mounted on a shaft 40.  In Fig. 4 the label carrier 32 is in the position shown in full lines, in the vertical plane, and a handle 52 is in position A.  Moving the handle to position B turns the shaft 40, and a rod 50 contacts a cam 54, and is moved up to the position shown by dotted lines in Fig. 4, the label carrier 32 being turned on its shaft 36.  Moving the handle 52 further, to position C, brings the label carrier to the position shown in chain lines in Fig. 4, where it receives gum from the studs 56, which have rotated through the gum bath 12. Returning the handle to position A the arms 38 are pulled back by the springs 42, and the label carrier 32 is in a horizontal position above the stacker.  Continued movement of the handle to position D, Fig. 3A, turns the pinion 28 (by a one-way drive mechanism, not shown) and raises the stacker 18 so that the gummed label carrier contacts the top label in the stacker. Reversing the handle 52 to position A brings the stacker 18 down rapidly by springs 30, and a pin 60, Fig. 3A, swings a lever 62. This action moves a lever 68 from the full line position to the chain line position, Fig. 3A, and an arm 74 contacts the pin 50 on the label carrier, which forces the label carrier to turn on its shaft 36 from the full line position of Fig. 3A to that of Fig. 4.  The gummed label is then removed from the label carrier by hand. Specification 695,949, [Group XVII], is referred to.

Abstract: 345,454. Arc-rupturing in switches. ELLISON, Ltd. G. and ANDERSON, J., Wellhead Lane Works, Perry Barr, Birmingham. Feb. 27, 1930, No. 6496. [Class 38 (v).] In a high-power switch a plurality of spaced plates are arranged at right-angles to the direction of motion of a contact which moves through apertures in the plates to engage and disengage a fixed contact, a magnet pole passing through the plates and being arranged at one side of the apertures therein, and an iron or steel rod or rods being arranged parallel with the magnet pole, a magnet winding being situated at one end of the magnet pole and rods. As shown in the Figure the arcing contacts b carried by the bridge member are withdrawn from fixed contact plates a through apertures c in a series of separated insulated non-magnetic plates d arranged at right-angles to the motion of the contact. A radial magnetic field is produced in the spaces between the plates d by an electromagnet f on a central iron or steel rod e, the return magnetic path passing through a series of insulated magnetic rods g spaced around the periphery of the plates d, and a magnetic plate n. This radial field causes the arcs drawn between contacts a, b to be divided into short sections which are whirled around in the air spaces between the plates d until extinguished. The arcing contacts b together with the main contacts i which engage contacts h at the ends of the rods e are mounted resiliently on the bridge carried by the operating- rod k. The blowout coils f are connected by members between the contacts a and the lead-in conductors. If desired, the mains contacts may be omitted.

Title: Process for the polymerisation of basic compounds
IPC: C08F16/28
Filed: 1959-02-25
Abstract: The polymerization of monoethylenically unsaturated compounds containing at least one basic tertiary amino group in the presence of a catalyst is carried out in solution in 1:2-dichlorethane. Copolymerization may be carried out with other monomers such as acrylonitrile, which must not be used in a proportion more than 60% of the total monomers, vinyl acetate, formate, butyrate or benzoate, vinyl alkyl ketones, vinyl chloride or fluoride, vinylidene chloride, styrene or substituted styrenes, acrylic acid esters, or amides preferably substituted at the amide nitrogen atom or analogous derivatives of methacrylic, a -chloracrylic, crotonic, maleic or fumaric acids, isobutylene, butadiene or 2-chlorobutadiene.  The tertiary-amino-group containing monomer may be (i) a basic amide or ester of an aliphatic a :b -unsaturated di- or mono-carboxylic acid such as crotonic, furylacrylic, a -chloracrylic, methacrylic, ethacrylic, acrylic, maleic, fumaric or itaconic acids, e.g. acrylic acid-g -diethylamino-propylamide or acrylic acid-b -diethylamino-ethyl ester amongst many other examples given.  The basic monomer may also be (ii) a basic vinyl ether, e.g. b -diethylaminoethyl vinyl ether, b -morpholino-ethyl vinyl ether or 4-dimethylaminophenyl-1-methyl vinyl ether; or (iii) a vinyl heterocyclic compound, e.g. vinyl-imidazoles, vinyl-quinolines, vinyl pyridines, vinyl carbazoles or N-(2-pyridino)-acrylic acid amide; or (iv) a basic vinyl aryl compound, e.g. dialkylaminostyrenes, a list of which is given; or p  (v) an allylamine such as N,N-dimethylallylamine or N,N-diethylallylamine.  The polymerization catalyst is of the free radical type and may be a peroxide or an azo catalyst, e.g. azo-bis-(isobutyramidine hydrochloride) amongst a list of others. An activator may also be used as well as regulators such as mercaptans or terpenes.  The monomers may be added in stages to effect control over the temperature of polymerization.  The polymer products may be used for application to textiles to improve antistatic properties and fastness of dyes, as fixing agents in photographic emulsions, as binding agents, cationic precipitants, polymer stabilizers, as sizing agents and emulsifying agents.  A solution of the polymer in alcohol and dichlorethane together with fluoro-chloro-methanes may be used as a hair setting lotion for spray application.  The polymers may be used in combination with aminoplast resins, e.g. alkyl ethers of urea-formaldehyde or melamine-formaldehyde resins, e.g. the ethyl, propyl or butyl ethers, and may be applied to textiles, paper or leather in solution in 1,2-dichloroethane together with a wax such as chlorinated paraffin wax.  Usual additives such as dibutyl or dioctyl phthalate or a sebacic acid ester plasticizer or organic or inorganic pigments or fillers may be added.  Films may be made from a 1,2-dichloroethane solution of the polymers containing a polyglycidyl ether derived from 1,4-butanediol and epichlorohydrin.

Title: Improvements in or relating to ultra short wave radio communication systems
IPC: H04B7/04
Filed: 1947-03-10
Abstract: 642,657. Radio communication systems. RADIO CORPORATION OF AMERICA. March 10, 1947, No. 6696. Convention date, March 12, 1946. [Class 40 (v)] In an ultra, high frequency radio communication system comprising a transmitter and a receiver, both of which are directional towards one another, a plurality of separate directional aerials spaced at different heights are used at either or both the transmitter and receiver, to reduce fading effects. It is shown that in a receiver comprising an upper and a lower aerial, the arrangement can be such that the upper aerial is more sensitive to the direct ray and the lower aerial is more sensitive to the reflected ray. The signals from the two aerials are then used in a diversity reception system. The invention is particularly suitable for a relaying system utilizing a sub-carrier and employing angle modulation. Fig. 3 shows two directive aerials RA-300 and RA-301, each associated with a portion of a superheterodyne receiver, the demodulated signals at sub-carrier frequency from both being combined in output lead 309. Limiters are provided in intermediate frequency amplifiers 306, 306<SP>1</SP> so that the relatively weaker channel causes little extra noise interference. Alternatives provide for a common A.V.C. system to be supplied so that amplification in the weaker channel is substantially reduced (Fig. 7, not shown), or for a gating circuit to be provided (Fig. 8, not shown), which exercises selective control in response to control voltages proportional to the amplitude of the signals in each channel, so that only one channel is operative at any time to provide the output signals. In another arrangement, the two aerials may be connected in parallel the relative phasing being adjusted by varying the electrical length of the coupling transmission line, or by moving one of the aerials horizontally. The associated transmitter may also be provided with two or more vertically spaced directive aerials in parallel and with phase adjusting means, the receiver then having either one, or more than one, aerial. In this case, the signal is normally received from one of the transmitting aerials, but under fading conditions, transmission from the second aerial may be utilized. The apparatus employed in various parts of the system may be similar to that described in Specification 625,488.

Title: Method for controlling the thickness and crystalline grain structure of phosphate coatings formed upon metallic surfaces
Inventor: HELLER FERDINAND PHILIP
IPC: C23C22/77
Filed: 1959-02-26
Abstract: The thickness of coatings formed on metallic surfaces by chlorate-accelerated heavy-metal phosphate coating solutions under constant conditions of time and temperature is controlled by varying the concentration of chlorate present in the otherwise constant solution in inverse logarithmic proportion to the thickness of coating desired.  The grain size of the coating is simultaneously controlled since the coarseness thereof similarly varies as an invere logarithmic function of the chlorate concentration.  Where the coatings are formed by dipping, the chlorate concentration may be varied by injecting additional amounts of the chlorate or of the unaccelerated ingredients into the bath.  Where the coatings are formed by spraying, the chlorate concentration may be varied by (a) injecting the required amount thereof into the pipeline feeding unaccelerated solution to the spray nozzles, (b) using separate spray nozzles for a solution of the accelerator and for the unaccelerated solution, or (c) using separate spray nozzles for the unaccelerated solution and for the same solution containing the maximum desired chlorate concentration.  The example relates to the coating of steel panels using a sodium chlorate accelerated zinc phosphate solution.

Title: Improvements relating to power operated door equipment
Inventor: STRETTON HENRY JACKSON
IPC: E05F15/14
Filed: 1965-02-17
Abstract: 1,080,573. Power-operated sliding door equipment. G. D. PETERS & CO. (ENGINEERING) Ltd. May 10, 1966 [Feb. 17, 1965], No. 6785/65. Heading E2M. Power-operated sliding door equipment comprises driving means mechanically coupled to one or more sliding doors to open and close the door(s), remote control means connected to the driving means to control the supply of power thereto whereby an operator can actuate the driving means, and local control means adjacent to the door(s) arranged and adapted to control the supply of power to the driving means and to actuate the driving means, the local control means operating independently of fthe remote control means and including means for mechanically uncoupling the driving means from the door(s) whereby the doors can be moved by hand. As shown, a pair of sliding doors 16 is operated by a cable or chain 17 passing round pulleys 8 and 8a, pulley 8 being driven a rack 9 and pinion 10 mechanism. Normally, a pawl 5 engages a notch 18 in rod 7 and power is applied by an electric motor to the pawl, or a movable frame supporting it, so as to move the rod axially. The motor may be controlled from a remote panel and also by switch contacts 3 operated by a first cam 2 on cam shaft 19 which can be rotated by handle 1. Contacts 3 are in a power supply circuit independent of the remote panel control. Normally, handle 1 is in a vertical position, contacts 3 are open, and only the remote control is operative. If the remote control fails, handle 1 is turned to position 1b (2), closing contacts 3 and the door operating motor is energised. If the power supply and remote control fail, the handle 1 is turned to position 1c (4) causing pawl 5 to be disengaged from notch 18 on rod 7 by action of cam 4. Manual force may then be applied to either door to open the doors. Locking means for locking the doors in the open position may take the form of a plunger 12. Under normal conditions of door operation, the plunger is held away from rod 7 against pressure of spring 13 by cam 14 on shaft 19. But when the handle is moved to position 1c (4) (5) and the doors are disengaged from the drive, then the profile of cam 14 allows the plunger to engage with rack 9.

Title: Improved process and apparatus for the polymerisation of olefinic materials
IPC: C08F210/12
Filed: 1943-04-29
Abstract: <PICT:0582137/III/1> Apparatus for copolymerizing isobutylene and a diolefine (see Group IV) comprises a reaction vessel 1 provided with a cover 2 through which passes a shaft 5 of a stirrer 6, a catalyst supply pipe 24 provided with a spray head 25 and an inlet 18 for mixture of isobutylene, diolefine and diluent.  The vessel 1 is provided with a cooling jacket 7 through which refrigerant is circulated by inlet and outlet pipe 9, 11.  A slurry of polymer in diluent is discharged from outlet 27 into a heated receptacle 29 containing water or a hydrocarbon solvent.  Unreacted mixtures and diluent are discharged from the receptacle 29 by pipe 31 and from the reaction vessel 1 by pipe 22 to purifying and recycling apparatus.ALSO:In the process for copolymerizing isobutylene and diolefins at low temperature in the presence of a Friedel-Crafts catalyst, the reaction mixture contains an alkyl halide as diluent in the proportion of 1 : 1 to 5 : 1 by volume of the reactants, an external refrigerant is used, the rate of addition of catalyst is controlled, and the mixture is stirred by a stirrer rotating at not less than 500 r.p.m.  The diolefin may be conjugated and of the formula <FORM:0582137/IV/1> where R, R1, R11 and R111 are hydrogen or an alkyl group of less than 8 carbon atoms, e.g. butadiene, isoprene, piperylene or dimethyl butadiene, or unconjugated, e.g. dimethallyl. The diluent may be methyl, ethyl, propyl or butyl chloride.  Suitable refrigerants are liquid carbon dioxide, ethylene, methane, ethane, ammonia or sulphur dioxide.  When the apparatus (see Group III) is sufficiently cooled by circulated refrigerant a mixture of olefin, diolefin and diluent is passed into the reaction vessel and vigorously stirred.  Catalyst is injected at a controlled rate to keep the copolymer in the form of a fine grained slurry.  The polymerization is stopped by discontinuing the catalyst supply and the slurry is discharged into a heated receptacle containing water or a hydrocarbon solvent, from which it is recovered as a slurry in water or a viscous solution in the solvent.  The product may be curred by heating with sulphur.  The Specification as open to inspection under Sect. 91 describes also the use as diluents of carbon disulphide, ethylene dichloride, chloroform, methane and ethane.  There is also described the polymerization of isobutylene alone, and the copolymerization of isobutylene with styrene or dimethyl styrene, and the substitutes for isobutylene of propylene, isopropyl ethylene and methyl ethyl ethylene.  This subject-matter does not appear in the Specification as accepted.

Title: Machinery for shrinking fabrik
IPC: D06C7/02
Filed: 1973-02-13
Abstract: 1364398 Finishing fabrics DRABERT SOHNE 13 Feb 1973 [14 Dec 1972] 6917/73 Heading D1S [Also in Division G3] A fabric shrinking machine comprising a steaming device 2, a drying device 4 over which the fabric glides downwards, and endless ascending conveyor belt 10 following the device 4 and a cooling device 11, is characterized in that at each transfer point of the fabric between the devices 2, 4 and between the device 4 and the belt 10 there is provided a pair of non-contact reflection transducers 6, 6a and 13, 13a, respectively, one pair of which, in dependance upon two limit positions r 1 , r 2  of the fabric 1 at the corresponding transfer point acts on a take-off roller 9 following the device 4 and the other pair of which acts on a guide roller 12 of the belt 10 to effect an increase or decrease in speed of these rollers to increase or decrease the speed of the fabric 1. In one embodiment, Fig. 1, the fabric 1 passes around a steaming roller 2 and is moved tension-free over the drying device 4, a curved transfer surface 5 and a pair of transducers 6, 6a being positioned therebetween. Preferably, the transducers 6, 6a are either pneumatically operated or light operated to direct a gas jet, e.g. air, or light, respectively, onto the fabric 1, and the reflected gas or light is picked up by a detector element within the transducer so that a pulse is generated and fed to an amplifier (7) or (7a), Fig. 5 (not shown). After amplification, the pulse is fed to an adjusting device which, through a rack and pinion, controls the speed of the take-off roller 9. When the fabric 1 reaches the position r 2 , Fig. 3, the speed of the roller 9 is decreased to prevent the fabric becoming tensioned and when the fabric reaches the position r 1 , the speed of the roller 9 is increased to prevent excessive sagging of the fabric 1. Between the roller 9 and the belt 10, a similar arrangement comprising transducers 13, 13a and a curved transfer surface (14), Fig. 4 (not shown), is provided to control the speed of one of the guide rollers 12 of the belt 10. A rough manual adjustment of the speed of the rollers 9, 12 may be made by a hand wheel (19), (19a), Fig. 5 (not shown), acting on the rack and pinion control. At least one transducer, e.g. 6a, 13a, of each pair is mounted in a heatable tube to exclude any adverse influences of steam on the measuring instruments. In another embodiment, Fig. 2, steaming is effected on an endless conveyor belt 3.
