Abstract: 927,716. Laminates. AERO CONTROLS Ltd. Dec. 1, 1959 [Sept. 1, 1958], No. 28074/58. Drawings to Specification. Class 140. A constructional laminated material is produced by assembling a lamina of felted asbestos fibres impregnated with phenol-formaldehyde resin in amount between 30 and 40%; on to a lamina of a metal which will bond to the lamina of asbestos fibres and phenol-formaldehyde resin solely upon the application of pressure and heat, and subjecting the assembly to pressure and heat. The lamina of felted asbestos fibres and phenolformaldehyde resin may be sandwiched between two laminµ of metal. The metal may be stainless steel, aluminium, an aluminium alloy or titanium, and may be flat or corrugated, or preformed to a desired shape or may be anodised before bonding. If a second metal lamina is used and is of, e.g., copper, it may be removed after the other layers have been bonded together. According to the Provisional Specification, a further layer of expanded resin may be applied to the laminate.

Abstract: 321,777. British Insulated Cables, Ltd., and Bullock, T. W. Oct. 1, 1928. Moulding-machines.-The pressure plate 9 of a moulding - machine is operated electromagnetically. The plate 9 is connected by a slide 18 and rod 17 to an armature which can be raised by an electromagnet 13 having one or more windings a, b which can be energized in succession, or separately, or two can be arranged in series or in parallel. For a long stroke the plate 9 may be connected to the core of a solenoid having a series of windings energized in succession by switches controlled by hand or by the core itself, or a combination of solenoid core and armature plate may be used. In a modification the rod 17, Fig. 3, is stepped and rests on loose armatures 31, 32, 33 which can be raised by magnets 28, 29, 30 arranged at different distances from their armatures. The nearest armature 31 at first exerts the greatest lift but ceases to act when it engages the magnet 28. The armature 32 then is near its magnet 29 and acts more powerfully until it engages its magnet leaving the armature 33, now near its magnet 30, to complete the stroke. The movement of the plate may be controlled by an adjustable dashpot 60, Fig. 2. The mould may be drawn by rods 37 adapted to engage the mould box and connected, as shown, to the core 24 of a solenoid 22 which may have a fixed core 23 to increase the force at the end of the stroke. The core 24 may also have a dashpot 35.

Title: Process for the manufacture of carbonyl compounds
IPC: C07C205/45
Filed: 1958-09-02
Abstract: Aldehydes and ketones are obtained by treating an organic compound containing one or more hetero atoms and one or more carbon to carbon double bonds, with an aqueous solution of a compound of a platinum group metal at 0 DEG C.-250 DEG C.  Hetero atoms specified are oxygen, sulphur, halogens, and nitrogen.  Metals specified are palladium and rhodium.  The halides sulphates, phosphates, acetates, and corresponding complexes of these metals may be used.  An oxidising agent is preferably also present in the reaction mixture, e.g. oxygen gas, persulphates, hydrohalic acids or salts, chromates, and other oxo-metallates.  Salts of polyvalent metals such as iron and copper may also be present. The reaction is preferably carried out at a pH of 0-2, and the catalyst solution may be periodically reactivated by oxidation with, e.g. oxygen.  The reactants may be brought into active contact by shaking, sprinkling, vibrating, or other methods.  The process may be carried out at pressures of 1-50 atmospheres in trickling towers, columns of filler bodies, or vessels provided with stirrers.  Examples are given of the production of p-methoxy - phenyl acetone from 4 - methoxy - 1 - propenyl benzene; 1,3,5-triacetyl benzene by ring closure of acetyl acetaldehyde which is first obtained from crotonaldehyde; acetaldehyde from acrylic acid, vinyl bromide, b -bromo styrene, and a -bromo-acrylic acid; acetone from crotonic acid, a -methoxy crotonic acid, 1-bromo propene, 2-chloropropene, a -chlorocrotonic acid, and crotonic acid amide; propionaldehyde from methycrylic acid, a -methacrylic acid amide, and allylamine; acetophenone from cinnamic acid, ethyl cinnamate, a -chlorostyrene, b -bromo-styrene, a -bromocinnamic acid, and cinnamic acid amide; pyruvic acid from maleic acid; methyl ethyl ketone from tiglic acid, a ,b -pentenic acid, 1-bromo butene (1), a -bromo-a ,b -pentenic acid and a ,b -pentenic acid amide; succinic acid aldehyde from itaconic acid; ethylidene acetone from sorbic acid; a -methyl acrolein and isobutyraldehyde from 1-chloro-2-methyl-propene (1); methyl glyoxal from allyl bromide, allyl chloride, 2,3-dibromopropene, and 1,3-dichloro-propene (1); pyruvonitrile from acrylonitrile; acrolein from allyl alcohol; p-methoxy acetophenone from p-methoxy styrene; 3,4-dioxymethylenebenzyl-methyl ketone from iso-safrole; n-propyl, n-butyl, and n-amyl methyl ketones from the corresponding a ,b -unsaturated acids, and their a -bromo derivatives; propiophenone from a -chloro-b -methyl styrene; benzyl methyl ketone from 2-chloro-1 or 3-phenyl propene (1); g -bromo-propyl methyl ketone from 1-bromopentene (4); p-chloroacetophenone from p-chlorostyrene and p-chloro-cinnamic acid; m-nitroacetophenone from m-nitro-styrene and m-nitrocinnamic acid methyl - [butanone - (2) - yl - (4)]-sulphone from the corresponding butene compound.

Title: Improvements in and relating to systems employing electron discharge devices
IPC: H04L27/04
Filed: 1930-09-20
Abstract: 369,552. Valve modulating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kaar, I. J. ; 10, Troy Road, Schenectady, New York, U.S.A.) Sept. 20, 1930, No. 28158. Convention date, Sept. 20, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] An auxiliary valve 17 is arranged to take an increased load from the supply rectifier 8, 9, 10 when the load taken by the power amplifier 3 decreases, during non-keying periods, and vice versa, thus maintaining a steady voltage on the plate of the amplifier. Normally the impedance of the amplifier 3 is infinite and the total load is shared between the shunt resistance 13 and the plate-filament path of the auxiliary valve 17. When the signalling key 7 is down, the current through the amplifier increases ; but the resulting grid current passing through the resistance 18 increases the negative bias on the grid of the valve 17, and so reduces the current through that valve to an extent which counterbalances the increased current taken by the amplifier. The shift of the load from the amplifier 3 to the compensator 17 occurs without any time-lag, and therefore serves to prevent any distortion due to anode-voltage fluctuations in high-speed keying.

Patent GB-1107167-A (GB)
Title: Process for the preparation of odourless or substantially odourless hydrocarbons
IPC: C07C7/171
Filed: 1966-06-23
Abstract: A hydrocarbon mixture consisting substantially or completely of C3-C5 normal and/or iso-alkanes is rendered odourless by a process comprising contacting the hydrocarbons in the liquid state with concentrated H2SO4, separating the hydrocarbon and acid phases, and then distilling the former. The acid may be of 80-95% by weight concentration and used in an amount 3-5% by weight of the hydrocarbons to be treated, the fresh acid added preferably being of 98% concentration.  The acid treatment is effected in a mixer at 0-50 DEG  C. in less than 10 mins. using at most 150 parts by vol. acid phase per 100 parts hydrocarbon phase, and is followed by separation of the phases in a settler and de-acidification of the hydrocarbon by means of a solid caustic alkali bed or, more preferably, a neutral or alkaline wash liquid such as water, milk of lime, NaOH or KOH, the pressure being sufficient to maintain the liquid phase of the hydrocarbon.  The subsequent fractional distillation employs a reflux ratio of at most 5:1 and may, if required, be operated to separate odourless propane and butane, for example, individually. The products are useful as aerosol propellants.

Abstract: 434,571. Signs. BUTCHER, H. V., 10, Shirley Street, Sydenham, and FIELD, W. S., 148, Gloucester Street, both in Christchurch, New Zealand. Oct. 3, 1934, No. 28286. Convention date, Oct. 16, 1933. [Classes 3 (i) and 3 (ii)] [See also Group XI] In an illuminated sign in which light from a concealed source 4 is projected by a parabolic or like reflector 5 lengthwise of an elongated casing 1 having one or more openings 2 in its longer sides, and in which prismatic glass screens 6 are arranged behind the openings to direct the light outwardly therethrough, means are provided to reciprocate the prismatic screens lengthwise of the casing so as to produce glittering effects. For this purpose the screen 6 may be supported by means of a pair of pivoted links 8 and connected by a rod 9 with a crank 10 rotated by an electric motor within the casing. A light source and reflector may be disposed at each end of the casing and additional reflectors may be provided to redirect stray rays through the openings 2. The inner surface of the screen 6 is formed with transverse prismatic ridges, its outer surface may be flat or formed with longitudinal rounded ridges, and it may be built up from a number of prismatic rods mounted in a frame. A sign may be formed by painting letters or pictorial matter on the outer surface of the prismatic screen, but preferably such a sign is formed on an outer glass sheet 7 having a rough or studded surface. In order to produce changing colour effects, the light source may be surrounded by a drum, the periphery of which comprises a series of transparent or translucent panels 11 of different colours and which is rotatable about a tubular horizontal axle 12. Alternatively, a rotatable colour disc may be arranged in front of the reflector 5. In each case therotation may be obtained by means of the electric motor which reciprocates the prismatic screen.
Patent GB-520830-A (GB)
Title: Improvements in or relating to closing mechanism for electric circuit-breakers
IPC: H01H3/60
Filed: 1938-09-29
Abstract: 520,830. Automatic circuit-breakers; actuation of switches. REYROLLE & CO., Ltd., A., and CHRISTIE, J. Sept. 29,'1938, No. 28298. [Class 38 (v)] Closing mechanism for a breaker comprises a gravityinfluenced inertia device operatively connected to the breaker-moving parts to close or assist closure, and means for disengaging or rendering ineffective such connection when the breaker reaches its closed position and allowing the device to continue to move and so gradually dissipate its surplus energy. The mechanism provides a smooth closing action not only against the blow-out forces produced by closure on a fault-current but also when resistance is small, as when the breaker is tripped during the closing action. The shaft 10 is connected through holding and tripping mechanism to the movable contact (not shown), and released to close by rotation of shaft 12. The shaft 10 carries a crank 17 which is connected by a toggle 18, 19 to one arm 16 of a bell-crank which is pivoted at 15 and carries a weight 13 on the other arm. In the open position of the breaker, Fig. 1, the links 18, 19 are just over the dead-centre and the line of the toggle is remote from pivot 15 and relatively near to the shaft 10, whereas when the weight 13 has moved the parts to the closed position, Fig. 2, the line of action is at right-angles to crank 17 and in line with arm 16. The torque is thus progressively applied to shaft 10 and is a maximum at the closed portion where the blow out forces are largest, whereas the rate of movement of the shaft 10 progressively decreases until, at the closed position, it may be as small as desired, any residual velocity after the retaining latch is passed being taken up by a stop. At the closed position, the pin 22 engages the link 18 whereby further downward movement of the weight causes the link 19 to rotate further and the pin 20 to travel down slot 21, thus allowing the weight to swing idly. Although the kinetic energy of the weight assists the final closing movement, its potential energy is relied upon to complete the closing movement in any circumstances. When tripped open, the shaft 10 returns to the latched position (Fig. 1), the weight being raised against the stop 23 to restore the toggle. The mechanism is applicable to a number of breakers arranged in a row by providing clutches or the equivalent for connecting it to the breaker to be closed.

Abstract: 732,347. Digital electric calculating apparatus. STANDARD TELEPHONE'S & CABLES, Ltd. Nov. 21, 1950 [Dec. 2, 1949], No. 28421/50. Divided out of 732,341. Drawings to Specification. Class 106 (1). Electrical recording apparatus comprises means for recording information on a recording medium, a device in which a number of instructions are permanently stored, each instruction relating to the manner in which information is to be recorded, input equipment over which information and signals relating to such information are received, each signal identifying one of the instructions, a discriminating device to which incoming signals are applied, and means responsive to determination by the discriminating device of the identity of a received signal to select the appropriate instruction and cause the recording device to record the information in a manner determined by the selected instruction. The embodiment described is a modification of the output equipment for an electronic computer described in Specification 732,341, in which each individual result leaving the computer is preceded by a composition instruction which controls the recording of the result. In the present case certain so-called " multiple instructions " are "built into the apparatus by prearranged connections which are under the control of a gas-tube counting circuit or distributer (Fig. 5, not shown). These instructions can be selected by signals accompanying the output data to control the recording of results. The selecting means comprises a coincidence gate circuit individual to each instruction-identifying signal. The equipment can be operated in this way or in the manner described in the Specification referred to, means being provided to determine which alternative is to be employed. It is possible to re-use a particular multiple instruction for more than one set of individual results, employing a counter to give the number of times of use. The inlet switch, instead of feeding the decoder and the arithmetic unit alternately, directs all the results to the arithmetic unit until the counter registers a predetermined number of operations. Specification 711,561 also is referred to.
