Filed: 1972-02-11
Abstract: 1351888 Locks; keys INTERNATIONAL BUSINESS MACHINES CORP 11 Feb 1972 [19 March 1971] 6500/72 Heading E2A  A lock-and-key system comprises a memory 31 in the form of a disc having discrete regions 1, 2, 3, 4 .. &c one of which is selected for reading by an address code on the front part of the key, Fig. 1, and the memory data thus read is compared with that encoded on the rest of the key to release the lock if they match. The reading of both key and memory is optical, that used for the key employing non-visible, e.g. infra red, light so that the indicia on the key may absorb this light without being visible. The card itself may be of P.V.C. filled with titanium dioxide. The readers for both memory and key comprise light-carriers in the form of fibreglass bundles 45, 49 and a detector 51. The code information on both memory and key card is represented in terms of binary intervals between marks, and reading may be performed as described in Specification 1324223. Detectors convert the equal or unequal pulses into digital pulses (Figs. 8a and 8b, not shown). As shown in Fig. 7A, analog coded signals read from the key and memory are fed in at 702 and 704 respectively, and are converted at 703 and 721 (both described with reference to Fig. 7B, not shown) to binary digital sequences. The 'Address' parts of the information are compared at 713 and if they agree an enabling signal is sent via gate 751 to gate 755. Then the datas of the key and memory sector are compared at 753 and also fed to gate 755, insertion of the card enabling the remaining input of this gate, which in turn, enables one input of output indicating gates 757, 759, 761, 765. The remaining inputs of these gates from 706 and 708 are derived from optically scanned punched holes round the periphery of the memory disc indicating whether a card has been issued or cancelled.

Abstract: 180,744. Remington, A. A., Garner, J. R., and Lancashire Ordnance Accessories Co., Ltd. Feb. 28, 1921. Spray carburettors.-The rate at which fuel passes through a valve-controlled orifice supplying the fuel nozzle is regulated by two controls each operative independently of the other, the one actuated by the movement of the throttle valve, and the other depending upon variation, due to engine suction, of the depression, either in an auxiliary chamber containing the needle valve and having an adjustable air inlet, or on a spring- controlled piston the movement of which varies the opening of the orifice. As shown in Fig. 1, the fuel nozzle A is provided with orifices a<1> supplied with fuel from an auxiliary chamber C fed from a float chamber D through an orifice F controlled by a needle valve H. The top of the valve stem is screw-threaded and is provided with a cap h<1> against which bears a cam e<2> on the spindle e<1> of the throttle valve E. The cam is so shaped that a rich mixture is supplied at both small and large throttle openings, but a weaker mixture at intermediate positions. The chamber C is provided with an air inlet g<1> fitted with a needle valve G by means of which the depression in the chamber, and hence the fuel flow, is controlled. The cap h<1>, which is adjustable to provide a hand control of the needle valve H, may be interconnected with the valve G. A pilot nozzle J communicates with the chamber C through a passage j<1>. An air passage a' is provided centrally of the fuel nozzle. In the modification shown in Fig. 4, the needle valve H is controlled by the throttle cam e<2> and by a suction-actuated piston K coupled to the cap h<1> on the top of the valve. A hand-control is provided by either (1) forming the fuel orifice F in an adjustable plug f<1>, or (2) providing a handactuated screwed sleeve which controls the tension of the spring k<2> acting on the piston K, or (3) making the square hole in the top of the chamber C through which the squared portion k<3> of the valve spindle passes, in an angularly adjustable sleeve. In further modifications, two orifices F are provided, one of which is supplied with fuel by gravity and the other by suction, one or both of the orifices being fitted with the two contacts as described above. The fuel passes from the orifices to two fuel nozzles or to two sets of concentric fuel orifices. The mixture may pass through a heating-chamber, for example of the kind described in Specification 178,137.

Abstract: 1410427 Compensating time displacement of parallel signals ENTREPRISE DE RECHERCHES ET D ACTIVITES PETROLIERES (ELF) 12 Feb 1973 [24 Feb 1972] 6699/73 Heading H3H In compensating skew of binary data recorded on parallel tracks of a kinematic magnetic storage device by comparing the time position of data pulses on each track in turn with clock pulses recorded on a reference track, only those clock pulses which at least partially overlap in time with a data pulse are taken into account, the displacement for each track is averaged over a given number of measurements and stored, and appropriate delays are then connected in the channels to correct the skew. In Fig. 1 data pulses E1 and reference pulses E2 pass through gating and logic circuits 4 and 6 which control a counter 10 and register 12 to accumulate clock pulses from 8 in accordance with the magnitude and sign of the time displacements. A counter 16 stops accumulation after M measurements and divider 14 divides the accumulated count by M. The result is displayed at 22 and fed to means 23 for connecting the appropriate skew correcting delays into circuit.
Patent GB-824605-A (GB)
Title: Improved process for preparing aryl succinonitriles
Filed: 1958-03-03
Abstract: The invention comprises a process for producing arylsuccinonitriles by reacting an unsubstituted aromatic or aliphatic aldehyde, or an aromatic aldehyde substituted by alkyl, alkoxy or chlorine, with an alkali metal cyanide and either an aryl methylene cyanide which may be substituted with alkyl, alkoxy or chlorine on the aryl group, or the corresponding aryl methylene chloride, in the presence of a compatible diluent.  The term "aromatic aldehyde" is defined to include heterocyclic aldehydes of an aromatic nature, e.g. 2-thiophene-aldehyde.  The components are reacted together at atmospheric pressure in the presence of a diluent in which all the reactants are appreciably soluble, and which is inert to the reactants under ordinary conditions, e.g. methanol or methanol and water.  Between about 50 and about 200 mol. per cent excess of an alkali metal cyanide, e.g. sodium cyanide, and about 5-30 mol. per cent excess of the arylmethylene cyanide are used.  If an aryl methylene chloride is used, e.g. benzyl chloride, an excess of alkali metal cyanide sufficient to produce the above amount of excess aryl methylene cyanide "in situ" should be used.  Ordinarily all of the alkali metal cyanide is placed in the diluting agent and the mixture heated to 30-80 DEG  C.  From about one third to about one half of the aryl methylene cyanide is then added, followed by the aldehyde and the rest of the aryl methylene cyanide, sometimes with additional diluting agents.  Examples are given of the preparation of a ,b -diphenylsuccinonitrile; a -(p-methoxyphenyl) - b  - phenylsuccinonitrile; a  - (p - chlorophenyl) - b  - phenylsuccinonitrile; a ,b  - di - (p-chlorophenyl) - succinonitrile; a  - (p - isopropylphenyl) - b  - phenylsuccinonitrile; a -phenyl-b -propylsuccinonitrile; a -(p-methoxyphenyl)-b  -(p - chlorophenyl) - succinonitrile; a  - (3,4 - methylenedioxyphenyl) - b  - phenylsuccinonitrile. Other aryl succinonitriles specified are a  - (o - chlorophenyl) - b  - phenylsuccinonitrile, a  - (p - methylphenyl) - b  - phenylsuccinonitrile, and a  - phenyl - b  - (m - chlorophenyl) - succinonitrile.  Starting materials specified are benzaldehyde, anisaldehyde, p-chlorobenzaldehyde, butyraldehyde, piperonal, 2-naphthaldehyde, 2 - thiophene aldehyde, veratraldehyde, 4 - phenylbenzaldehyde, valeraldehyde, caproaldehyde, veratraldehyde, m-chlorobenzaldehyde, o - chloro - benzaldehyde, m - tolualdehyde, p-tolualdehyde, benzyl cyanide, p-chlorobenzyl cyanide, benzyl chloride, p-chlorobenzyl chloride, 2-naphthyl methylene cyanide, 4-phenylbenzyl cyanide, 3- and 4-methoxybenzyl cyanide, 4-ethoxybenzyl cyanide, 3- and 4-methylbenzyl cyanide, 3-ethylbenzyl cyanide and 3-and 4-chlorobenzyl cyanide.

Abstract: 549,155. Lubricators. BENNIS COMBUSTION Ltd., and BENNIS, A. W. May 28, 1941. No. 6825. [Class 12 (iii)] Rectilinearly moving axles, such as conveyer chain spindles, are lubricated by a grease gun automatically moved into engagement with the end of each spindle in succession, moved with the spindle during lubricant feed and then disengaged and returned to the starting point. The grease gun A is carried in a housing C on a bar D hinged to parallel arms E, E<SP>1</SP> pivoted at F<SP>1</SP>, F<SP>2</SP> to a fixed framing F. The spindles H have nipples H<SP>1</SP> which engage arms on a shaft J so as to move a slide K mounted in a bracket K<SP>2</SP> on the framing F. The slide K has a tappet K3 engaging a roller E<SP>1</SP> on arm E<SP>2</SP> so as to move the gun A. Initial movement of arm E<SP>1</SP> brings the gun in engagement with the nipple, and further movement actuates the gun whilst travelling with the nipple. The gun is returned by spring L when the nipple clears the arm on shaft J. Bar D has a roller running on the framing F to carry the weight of the gun. The gun can be secured out of action by a hand-lever O which has a cam P moved to engage bar D and prevent its return by spring L.

Abstract: 422,021. Endless - belt conveyers. WHEELWRIGHT, J. S., The Corner, Three Elm Lane, Tonbridge, Kent, ABELL, G. H., Thurston, Orchard Way, Esher, Surrey, and STEWART, R. F., 36, Hadlow Road, Tonbridge, Kent. July 7, 1933, Nos. 6840/34 (divided out of 416,373, [Group XVI]), and 8622/34. [Class 78 (i)] [See also Group XVI] The drive to an intermittently movable conveyer is controlled by an actuator which travels with the conveyer during each forward movement thereof and at the end of the movement stops the drive to the conveyer, a device connecting the actuator with the conveyer being engaged therewith and disengaged therefrom at predetermined initial and final positions. As shown applied to apparatus for multicolour printing by means of screen-stencils, a web is fed through the machine by an endless rubber belt 10 driven from a shunt wound motor 32 through an electromagnetic clutch 34 which is thrown in when the stencilframe, in rising after an impression, closes a switch 43. Before the belt starts moving, an actuator 12 mounted on a base-plate 19 is frictionally engaged with the belt by pivoted claws 22 pressed on the belt by arms 13 which are pivoted to brackets 18 upstanding from the base 19 and support a roller 15 in the path of a bar 16 which descends as the stencil-frame rises. Near the end of the movement of the belt, an adjustable screw 26 at the forward end of the actuator engages a trip whereby a relay 45 closes a switch 46 which energizes a relay 47 adapted to close a switch 40 to cut out a resistance 37 in series with the field windings 36 of the motor 32 and simultaneously to open a switch 42 and thereby to include a resistance 38 in the armature circuit, the result being that the motor runs at reduced speed and the risk of overrunning of the conveyer is minimized. The actuator subsequently engages a second trip whereby a relay 49 opens a switch 50 to throw out the clutch 34. On the upward movement of the bar 16, the claws 22 are released and a dashpot returns the actuator to its initial position where it engages a trip momentarily closing a switch 53 for resetting the switches 40, 42, the trip being adjustable to vary the amount of advance of the belt 10. According to the first Provisional Specification the actuator comprises either a flat strip of steel alternately pressed on and released from the belt by rollers, or a roller rotated by the belt and adapted to actuate a rack engaging the trip device.

Title: Improvements in air-blast circuit-breakers
IPC: H01H33/83
Filed: 1961-02-24
Abstract: 924,613. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Feb. 24, 1961 [Feb. 27, 1960], No. 6846/61. Class 38 (5). An air-blast circuit-breaker has its contact movement controlled by a piston 7 in a cylinder 8 arranged so that one side of the piston is subjected to the constant pressure gas whilst the other side of the piston is subjected to a pressure which reduces, during contact opening, due to a restricted orifice entry 10. When highpressure air is admitted to the insulating housing 1 the tubular contact 3 is moved upward against the bias of a spring 6. The pressure on opposite sides of the piston 7 is almost equal owing to the passages 10, 11 and a channel 13 in the contact 3 but during the initial movement the channel 13 is sealed and the pressure in the lower part of the cylinder falls so that the contact velocity characteristic is as shown in full line in Fig. 3. This results in increased time of contact travel but reduces the kinetic energy by 75% as compared with an unrestricted moving contact (dotted line, Fig. 3). In the fully-open position the tubular contact 3 is sealed by an insert 5 in the exhaust chamber. Valves 14 in the piston 7 allow free flow of air during closing movement. The restricted orifice or passage 10 may be in the piston instead of the cylinder.

Abstract: 1,253,458. Electronic tachometer. GENERAL MOTORS Ltd. 15 Jan., 1970 [8 Feb., 1969], No. 6972/69. Heading H3A. [Also in Division G1] An electronic tachometer to be connected across the contact breaker points S of a coil ignition circuit (enclosed by dashed line) comprises a low pass filter R 1 -R 3 , C 2 , amplifying transistor T 1 , a differentiating circuit R 4 - R 6 , C 3 , a second amplifying transistor T 2  and an integrating circuit C 4 , M arranged to give a reading on meter M corresponding to the instantaneous rotational speed of an engine. The differentiating circuit may include a negative temperature coefficient thermistor R 6  to compensate for collector current variation. The circuit may also include a variable resistor R 5  for calibration of the meter. A square wave pulse proportional to engine speed with one edge composed of a decaying oscillation of high frequency due to ignition coil is developed across contact breaker points. A filtered square wave turns transistor T 1  off and on to charge and discharge a capacitor C 3 . Pulses of constant width and height are produced which are then amplified by T 2  and are applied to an integrating circuit C 4 , M to give an indication of engine speed. In the embodiment of Fig. 2 (not shown), the effect of transistor ageing is overcome by replacing capacitor C 4  with a resistor (R 8 ) to obtain a damped movement meter responding to the average D.C. level of the pulses. By a suitable layout, the electronic components and the meter are arranged to have opposite temperature characteristics so that thermistor R 6  of Fig. 1 could be replaced by a fixed value resistor (R 10 ).
