Title: Drive for ring rails of ring spinning frames
IPC: D01H1/36
Filed: 1964-09-01
Abstract: 1,069,164. Ring frames. F. STEFFENINI. Sept. 1, 1964 [Sept. 10, 1963], No. 35656/64. Heading D1D. In a ring frame having ring rails reciprocated by a compressed fluid device one or more rotatable pinions are mounted to move with the rails and engage with one or more rack guides on the stationary part of the spinning frame, the rack guide being adjustable relative to said pinion or said pinions and/or guides being relatively adjustable to each other. As shown a ring rail 10 is traversed by a series of spaced hydraulic devices and carries a shaft 19 on which are rotatably mounted pinions 5, 10, 15. Each pinion meshes with a pair of racks 7, 8; 17, 18; 27, 28; so any tendency of the rail 10 to move out of the horizontal is resisted. The racks are adjustable by means 33, 34, 35, 36 so as to compensate for wear in the parts. In Figs. 4, 5, not shown, each pinion (41) is associated with four adjustable racks (37, 38, 39, 40). In Fig. 7, not shown, a single rack (60) is associated with two pinions (61, 62) of which pinion (62) is fixed on a shaft (63) while pinion (61) is angularly adjustable on the shaft by a screw (67), see Fig. 10 not shown; thus the pinions are relatively adjustable to compensate for wear. In place of screw (67) a spring may be provided so that wear is automatically taken up. The teeth of the racks and pinions may be of resilient, selflubricating or stainless (non-oxidisable) material.

Title: Improvements in boxes or containers for hams
IPC: A47J27/20
Filed: 1929-11-22
Abstract: 335,810. Lomas, G., and Herd, A. Nov. 22, 1929. Heating and cooking vessels.-A container for compressing a ham during cooking is of rectangular cross-section and tapers from a point less than half-way from the top into a semi-circular base. The container is fitted with a heavily made base G to maintain the balance. A side plate B is adjustable to accommodate various sizes of hams by means of a screw C fitted with a moisture-retaining washer E. As the ham shrinks during cooking it falls into the lower part of the container and becomes compressed. Liquid is displaced from the bottom and rises to the top of the ham. During cooling, therefore, the fats adhere to a plate J which is rested on top of the ham. Handles M, M<1> and a lid K are provided.

Title: Compatible image-reproducing system
IPC: H04N11/14
Filed: 1955-12-13
Abstract: 785,575. Television. HAZELTINE CORPORATION. Dec. 13, 1955 [Jan. 17, 1955], No. 35782/55. Class 40 (3). In a compatible colour television receiver utilizing a single-gun picture reproducing tube having a screen composed of a plurality of colour reproducing strips and a co-operating colour-switching grid, spurious colour patterns which occur when only monochrome signals are being received or, when a monochrome image is reproduced from received colour signals, and which arise from heterodyning of the highfrequency range (3-4 Mc/s.) of the luminance signals with the colour-switching operating (3.6 Mc/s.), are minimized by arranging that the beam of the tube is intensity modulated by signals having frequencies below the colourswitching frequency and differentially velocity modulated, in a direction lengthwise of the colour strips, by signals having frequencies in the vicinity of the colour-switching frequency, Fig. 1, shows one embodiment employing a receiver which includes conventional circuit arrangements for processing a received NTSC type signal for sequential display. When colour signals are being received the A.P.C. system 27 develops a control potential which maintains the colour killer 36 inoperative and so allows the axis selector 20, the modulator 23 and the synchronous detector 25 to function normally. In the absence of colour signals (i.e. when monochrome signals are being received) system 27 fails to develop the control potential and the colour killer operates to block entirely the circuits 23 and 25 and conditions the axis selector 20 to pass, continuously, signals in the band 3-4.2 Mc/s. which are derived from amplifier 19. These signals, which include signals in the vicinity of the colour switching frequency, are then supplied via filter 21 and amplifier 22 to an auxiliary deflecting coil 14d which effects a differential deflection of the tube beam in a direction lengthwise of the colour reproducing strips. To complete the modulation of the tube beam the signals lying in the band 0-3 Mc/s. (which do not produce spurious colour patterns) are derived via filter 17 and supplied through adder 13 to the tube cathode to amplitude modulate the beam. If it is desired to reproduce received colour signals in monochrome the effect of the colour killer 36 on units 20, 23 and 25 may be produced by means of a switch. In a second embodiment amplitude modulation of the tube beam is effected by signals in the 0-1.8 Mc/s. band and differential velocity modulation by signals in the band 1.8-4.2 Mc/s. (Fig. 3, not shown). Circuit details of some of the " blocks " of Fig. 1 are described with reference to Fig. 2 (not shown).

Title: Cross-Linking of polymers
IPC: C08G81/02
Filed: 1968-07-26
Abstract: 1,162,080. Cross-linked materials by coupling block polymers. POLYMER CORP. Ltd 26 July, 1968 [4 Aug., 1967], No. 35819/68. Heading C3P. A cross-linked polymeric material is obtained by preparing a mixture of a first block polymer having one reactive chain end, a second block polymer having at least two reactive chain ends and a coupling agent having at least three reactive sites, allowing the coupling agent to react with the block polymers, and extracting the resultant cross-linked polymeric material. The reactive chain ends may be " live," i.e. catalyst residues prior to deactivation, which is preferred; polymers having deactivated endgroups, e.g. from emulsion polymerization may also be used. The polymer mixture may be obtained by separately polymerizing in the presence of mono- and difunctional initiators respectively and then mixing or by a single polymerization using a mixed initiator system. The mixing may be carried out in solution. Suitable coupling agents include SiCl 4 , polyglycols, polyamines, polyaldehydes, polyepoxides, polyketones, polyhalides, e.g. SiBr 4 , SiCl 3 .H, 1,3,5 - tri - (bromomethyl) benzene, and reagents having various reactive sites, e.g. 1,3-dichloro-2-propanone. In the example, polystyrene-polybutadiene is formed by sequential polymerization in benzene using sec-butyl lithium, polystyrene-polybutadienepolystyrene is formed by sequential polymerization in benzene using dilithiodiisoprene, and the living polymers mixed with SiCl 4  in benzene. In comparative experiments, each of the living polymers are separately mixed with SiCl 4  and the resulting polymers blended.

Title: Alarm installation
IPC: H04M11/04
Filed: 1960-10-19
Abstract: 940,070. Automatic exchange systems. TELECTRONIC S.A. Oct. 19, 1960 [Oct. 28, 1959], No. 35852/60. Drawings to Specification. Heading H4K. An alarm installation connected to a telephone system is adapted when operated to feed into the telephone system at least one alarm signal selected from two or more alarm signals permanently on record in the installation and intended to be directed to different receiving stations; the installation includes at least one detector circuit, an endless magnetic tape carrying the recorded alarm signals, a device for reading-out the recorded signals, a selection device supplying the read-out signals selectively to the telephone system, a control device for stopping transmission of the alarm signals, and self-contained power supplies for the installation, the control device comprising a local control and a device able to receive a signal transmitted over the telephone system to operate the control device remotely, and the selection device being controlled by additional signals recorded on the tape and associated with each alarm signal. As described, an endless loop of tape carries a series of messages, each comprising dial impulses, the information to be sent, and a sign-off signal. The sign-off signal is of such a length as to cause release of a slow-release relay by blocking a transistor (dial impulses being produced similarly) and hence release of the telephone line. The next message is therefore not transmitted, but its sign-off signal causes a further switching operation which re-connects the line. Thus, alternate messages are sent. If the tape loop contains an odd number of messages, all are sent, whereas only half are sent if the loop holds an even number. During any one of the gaps in transmission the called station may dial the alarm station, the resulting ringing current bringing about a switching operation to stop the alarm apparatus which goes home (a closedown signal, even longer than the sign-off signal, initiating release). There may be two (or more) alarm detectors, e.g. one for fire and one for burglary, one despatching the odd-numbered messages and the other the even-numbered.
Patent GB-454405-A (GB)
Title: Improvements in or relating to lined envelopes and similar postal wrappers
IPC: B65D27/16
Filed: 1935-12-30
Abstract: 454,405. Envelopes &c. KRAUSE, M., 93, Alexandrinenstrasse, Berlin. Dec. 30, 1935, No. 35965. [Class 146 (ii)] In a self-adhesive envelope or like wrapper provided with a lining of tissue paper or other material the lining is adapted to form an interposed layer between the parts coated with adhesive prior to the sealing of the envelope. The lining may be extended as a free flap to cover either the adhesive on the back of the envelope or that on the closure flap. In another form, the portion of the lining which extends over the closure flap is not large enough to cover that flap and is not gummed thereto nor to the inside of the front of the envelope, but is folded over the back of the envelope to lie between the lavers of adhesive of the back and closure flap. When a letter is inserted the lining is held back in position and cannot extend between the layers of adhesive. In the form shown in Fig. 4a, the lining i is arranged to cover the adhesive g on the closure flap but not to extend to the bottom of the envelope ; when a letter is inserted in the envelope, it will push the lining to the bottom, and the adhesive on the closure flap will no longer be protected. The latter construction may be modified by arranging the lining to cover the adhesive on the back of the envelope, so that the adhesive will be uncovered when the letter is inserted in the envelope. In the form shown in Fig. 6b, the lining i is stuck at its outer end portions inside the envelope so as not to overlie either layer of adhesive, and on closing the flap the lining slips down, as shown, to fold in between the two layers of adhesive g, f.

Title: Improvements in or relating to telecommunication systems
IPC: H04Q5/08
Filed: 1963-09-13
Abstract: 990,007. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 13, 1963 [Sept. 14, 1962], No. 36113/63. Heading H4K. In an arrangement in which party-line substations T1, T2 ..., Fig. 1, are all normally connected to the line VL, the transmission of frequencies f 1 , f 2  ... from the exchange disconnects all except one, so that they are connected one at a time in succession, the normal condition being restored in response to a frequency f 0 . For this purpose, each substation includes a bistable polarized relay A1, A2 ... of which each winding is associated with a rectifier bridge and a pair of tuned circuits, as shown in Fig. 2a for relay A3. In Fig. 3, two pairs of substations Tn1, Tn2 and Tn3, Tn4 are distinguished by the use of oppositely-poled rectifiers, and the connections of the substations of each pair are controlled by frequencies f 1 , f 2 , f 0 . The line VL, Fig. 3, terminates at the exchange in a line circuit, Fig. 5, in which relay R, fed with A.C., energizes when a call is initiated. Relay H follows, and relay S pulls up if the calling substation is Tn3 or Tn4 and reverses the line connections. Relays V, F operate temporarily and apply frequency f 1  to the line to disconnect Tn2 and Tn4. The loop is tested by relay P which responds if the calling substation is Tn1 or Tn3, in which case the line is extended to a line finder AS and further operation of V, F is prevented. If relay P fails to respond, V, F re-operate, and since relay U is now up, frequency f 2  is applied to the line to connect Tn2, Tn4 in place of Tn1, Tn3. Relay P now energizes. Relay D starts the finder AS and in due course relay T energizes in the test circuit, in which relay S holds if operative. An individual meter Za is selected according to the condition of S and of a relay K (not shown) which is dependent on the second operation of F. When release occurs, relays T, P fall back in turn and the successive operation of relays X, Y controls relays V, F to send first frequency f 2  and then frequency f 0  to restore the original connections of the substations. For incoming calls, the substations have separate appearances in the banks of the final selector LW, the talking wires are reversed at the frame Vh to distinguish between Tn1, Tn2 and Tn3, Tn4 and the test wires for Tn2, Tn4 include relay E. If only relay T energizes, frequency f 1  is sent, whereas if E is operative U is connected up to send frequency f 2 . Relay P then operates to switch through the line VL to the final selector.

Title: Improvements in clamping apparatus for tension locked printing plates
IPC: B41F27/10
Filed: 1946-12-06
Abstract: 619,399. Printing surfaces. WOOD NEWSPAPER MACHINERY CORPORATION. Dec. 6, 1946, No. 36165. Convention date, Aug. 13. [Class 100(ii)] Stereotype plates 6 and 7 are clamped on a rotary cylinder 1 by a clamp which is moved by rotation of the cylinders to the clamping and unclamping positions by an operating member controlled by a box cam fixed against rotation adjacent one end of the cylinder. The plate 6 has pockets 30 and 31 which receive pivoted clamping fingers 9 and 32. the latter being mounted on a shaft 33 and exerting clamping pressure by springs 34. Fingers 9, mounted on a shaft 11 are operatively connected with a cam roller 16, which rotates with the cylinder, by an adjustable link 13, and are urged into clamping position by a spring 36. A cam surface 17 co-operates with a cam surface 18 to form a box cam which moves the roller 16 positively into and out of two positions to effect the clamping and unclamping of the plate 6. The cam surface 18 is pivoted at 43 and is brought into its operative position by a lever 19 through gearing 51 and 26 and is held in operative and inoperative position by a spring 21. The lever 19 is operated to effect the unclamping while the cylinder is not positively driven, and the cylinder is given a turning or jogging movement to release the clamps. Trip blocks 24 and 24' secured to the cylinder engage a projection on a lever 25 during rotation of the cylinder to move the cam surface 18 to its inoperative position. In a modification which avoids the torsional deflection of the shaft carrying the clamping fingers, one set of fingers may be fixed on the cylinder and springs may be provided to exert a direct clamping pressure on other pivoted fingers, which are moved in to the clamping position as previously described. Specification 583,771 is referred to.

Title: Improvements in or relating to protection of shoes against soiling, abrasion, or thelike
IPC: A43B9/04
Filed: 1954-12-22
Abstract: The exposed stitches on the welts of footwear are protected against soiling and <PICT:0763428/III/1> abrasion by an easily removable strip extruded on to the welt in place of the adhesive tape previously used.  The upper surface 12 of the welt 8 is preferably first coated by a brush, sponge, nozzle or perforated wheel with a liquid which forms a substantially smooth surface to reduce the adhesion of the cover-forming material which is extruded over it. The coverforming material strip 20 is extruded from a nozzle 32 over the coated stiches 14 as the shoe is fed past by a feed roller 38 engaging the edge 22 of the welt and a similar roller, not shown, engaging the underside.  On completion of the shoe, the strip 20 can be readily removed.  Examples of the coating material are solutions in a volatile organic solvent of a high styrenebutadine copolymer resin or cellulose derivative such as cellulose acetate, cellulose nitrate, or cellulose acetate-butyrate or a thin dispersion of wax in a soap solution and solutions in water of ammonia-cut casein, ammonia-cut shellac or hydrolysed polyvinyl esters.  These materials may be adapted to improve the temper of the welt or its finish by depositing a lustre-improving agent.  Examples of the cover-forming material are solutions or dispersions in a volatile solvent of a vinyle resin, such as vinyl chloride/vinyl acetate copolymer or vinyl chloride/vinylidene chloride copolymers, or of propylene oxide, ketones such as acetone or methyl ethyl ketone.
