Title: Digital pulse amplifier
IPC: H03F1/52
Filed: 1962-10-24
Abstract: 1,006,262. Transistor switching circuits. SPERRY RAND CORPORATION. Oct. 24, 1962 [Nov. 6, 1961], No. 40299/62. Heading H3T. A pulse amplifier has means to limit the output current, means to suppress interference and means for automatic disconnection in the event of power failure. In the normal condition, the input at terminal 10 is positive, cutting off transistor 44, transistors 22, 24 are biased to be conducting, and transistors 20, 32 are biased to be cut off, resulting in the terminal 14 being at a negative potential. Transistors 24, 32 are cross-connected in a bi-stable circuit and in the event of the terminal 14 becoming short-circuit to earth, the increase in current through resistor 26 switches this circuit over to its other state disconnecting the terminal 14 from the negative supply. Application of a negative input to the input terminal 10 causes transistor 44 to become conducting after a time determined by the charging of capacitors 50, 52, resulting in transistor 22 becoming non- conducting and transistor 20 becoming conducting, thus connecting the output terminal 14 to earth potential. On restoring the input at 10 to a positive potential, the transistor 44 switches off after a time determined by capacitor 50 alone and the circuit restores to its normal state. A normally conductive transistor 18 is biased to become non-conducting in the event of the power supply becoming disconnected and is included to prevent false signals being fed through transistors 20, 44 since neither can conduct when transistor 18 is non-conductive.

Title: Novel polymers
IPC: C08F4/12
Filed: 1959-12-08
Abstract: Head-to-tail, linear polymers of unsaturated monomers of the general formula, CRIRII=CRIIIRIV, in which RI is different from RII, and RIII is different from RIV, and at least RI and/or RII are different from both RIII and RIV, and the radical R represents hydrogen, deuterium, tritium, alkyl, alkenyl, aryl, arylalkyl, cycloaliphatic, or organic groups containing oxygen, comprise macromolecules in which at least one of the two asymmetric C atoms of each unit, has the same steric configuration for portions, at least of the chain.  The polymers are generally di-isotactic and may contain erithro-di-isotactic, or threo-di-isotactic, structural units, as well as stereoblock units. The polymers are made by polymerizing a monomer of the above general formula in the presence of a stereospecific catalyst, and separating the mixture of polymers, by solvent extraction, into fraction having a different degree of steric regularity.  The catalyst consists preferably of a solid crystalline halide of a transition metal in which the metal has a valency lower than its maximum, and a metal alkyl of Group II or III of the Mendel<\>eeff Periodic Table.  The monomer polymerized may be in the pure cis or trans form, or a mixture of the forms. The polymerization is generally effected in an inert hydrocarbon solvent, and the polymerization temperature may be from -30 DEG  to -120 DEG C.  The monomers may be pentene-2, hexene-2, beta-methyl styrene, alpha-deutero-beta-methyl-ethylene, propenyl methyl ether, 1-methyl-2-ethoxy, or -2-isopropoxy-, or -2-butoxy, or -2-isobutoxy-ethylene, 1-ethyl 2-methoxy, or -2-isobutoxy-, or -2-butoxy ethylene, or phenylmethoxy-ethylene.  The polymerization catalyst may be aluminium di-ethyl monochloride, or aluminium mono-ethyl-di-chloride, or a mixture of an aluminium trialkyl and titanium trichloride.  Exemplified monomers polymerized are cis-alpha-deutero-beta-methyl-ethylene, transalpha-deutero-beta-methyl ethylene, propenyl methyl ether, 1-methyl-2-butoxy-ethylene, and 1-methyl-2-isobutoxy-ethylene. The polymers may be purified by conventional techniques, e.g. addition of alcohols.  The polymers can be die-cast, injection moulded, or extruded into fibres, or films.

Filed: 1960-12-05
Abstract: 963,544. Toasters. SUNBEAM CORPORATION. Dec. 5, 1960 [Dec. 30, 1959], No. 41785/60. Heading A4D. [Also in Division H2] In a thermal switch, a bimetal element is supported at its ends by two parallel support arms, one of which is resilient and pivotally mounted, a coil spring being connected between the arms to apply an endwise compressive force to the bimetal which is bowed so that it moves rapidly from one bowed position to an oppositely bowed position at a temperature which is varied by adjusting the resilient support arms by means of a cam. As applied to an electric toaster, the bimetal 133 is compressed between a rigid support 129a and a resilient support 136 pivoted at 139 and having an extension 138 carrying a screw 143 engageable by a cam 125 adjustable by a knob 126 from outside the casing 21. A coil spring 130 is stretched between the arms 129a, 133. A heater 108 is arranged below the bimetal inside a reflector 150. The bimetal is embraced by a forked lug 160b on a lever 160 pivoted at 161 and having two latch lugs 160e and 160g. These lugs co-operate with a hook 77a on a lever 77 carried by the bread supporting structure 62. The latter is slidable downwards on a rod 63 by a knob, Fig. 2, on a member 82 to a toasting position where it is latched against the return spring 67 by engagement of lug 160e with hook 77a, Fig. 7. In this position, a contact 88 resiliently carried by the structure 62 bridges fixed contacts 98, 99, and a cam 87 opens contacts 100, 101. Thus the toaster heating elements 55 are connected in series with the bimetal heater 108 and toasting commences. Eventually, the bimetal snaps upwards tilting lever 160 clockwise, Fig. 9, so that lug 160e is disengaged from hook 77a which is then engaged by a lug 160g. This allows the structure 62 to move upwards sufficiently to allow contacts 100, 101 to reclose to short circuit the heater 108 so that the bimetal recools. When it snaps back to its lower position, the lever 160 is moved back also and hook 77a is released so that the structure 62 moves upwards to eject the toast and open contacts 88, 98, 99 to de-energise the heating elements 55. The structure 62 has a lug 62d which engages with lost motion a dash pot plunger 72 so as to damp the final movements in each direction. The hook 77a may be disengaged from lever 160 at any time by tilting member 82 clockwise (Fig. 10) about its end 82d so that an arm 82e with a lug 82f tilts the lever 77 against the bias of a spring 80. Toasting elements 55 are wound on mica cards 51 only on sides facing two toasting chambers 22, 23 containing bread carriers 59 attached to structure 62.

Abstract: 1,142,260. Controlling vehicles. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. 14 Sept., 1967, No. 41921/67. Heading B7H. [Also in Division H1] A motor vehicle with an automatic gearchanging device comprising a system for overriding the operating elements 103, 104, 105 such as for fuel supply, braking and steering at the main driving position from a second driving position wherein each operating element at the main driving position is operatively connected to a servo-control device 200, 300, 400 drivable with auxiliary power and a controller 500 at the second driving position is arranged for controlling the servo-devices. As shown, in a tank or other heavy endless track vehicle, the control elements 103, 104, 105 are connected by linkages 108, 109, 110 to the fuel supply, braking and steering mechanism of the vehicle and are either operated by a driver at the main driving position when the controller 500 is inoperative or by electric servomotors in the similar respective servo-control devices 200, 300, 400 when the controller 500 is operative. Closing of a switch 501 by gripping of the grip 522 of the handle 521 of the controller 500 engages a clutch 207 between each motor 201 and shaft 203 on which the control element is mounted and applies to the motor an electrically releasable brake 208 in series with the motor thereby preventing operation of the control elements by the driver at the main driving position. Movement from the neutral position of the handle 521 in the direction F operates micro-switches to actuate the servomotor to successively increase the fuel supply in steps or in the opposite direction to F operates microswitches to apply partial or full braking: rotation of the handle 521 about the axis of the shaft 530 actuates the steering servomotor. The stepwise action of the control elements is controlled by switches actuated by cam-plates 211 to 214 on shafts 203, 202 geared to the motors. On the side of the controller is a handle (526), (Fig. 10, not shown) by which forward or reverse motion or neutral is obtained associated with an interlock (527/529) which prevents movement of the handle unless the handle 521 is in the brake applied position. The driver normally controls the automatic gear-change through a control 700 which is locked in position when the controller 500 is in use. A " kickdown " switch 525 is provided on the controller. The vehicle may be controlled through a wireles receiver 810 from a wireless transmitter 850.
