Filed: 1966-02-04
Abstract: 1,131,205. Date indicators. ETA A.G. EBAUCHES-FABRIK. Feb.4, 1966 [April 20, 1965], No.4965/66. Heading G3T. A calendar watch possessing an instantaneous date changing motion comprises a date indicating ring 7, capable of being driven by the watch movement and an entrainment member 9 carried by a driving spring 8 and operatively engaging the date indicating ring, the driving spring being mounted on a control wheel 5. The control wheel 5 is continuously driven by an hour wheel 2 via a reduction gear 6. The entrainment member 9 engages a tooth 10 of the date ring 7 so that as the wheel 5 rotates, the spring 8 tensions until the entrainment member reaches a rigid portion 20 of a hub 17 which is an integral part of the wheel 5. The force exerted by the spring on the tooth 10 then causes a detent 12, biased by a spring 15, to move out of engagement with another tooth and thereby allow the entrainment member 9 to advance the date ring 7. Reverse indexing of the date ring 7 during backward setting of the ravels is prevented by a cam surface 21 which pulls the entrainment member 9 out of engagement with the teeth 10.

Title: Fuel feeding and injection apparatus for oil burning internal combustion engines
IPC: F02M57/02
Filed: 1948-02-20
Abstract: 637,702. Supplying liquid fuel. CUMMINS ENGINE CO., Inc. Feb. 20, 1948, No. 5110. Convention date, April 26, 1943. [Classes 7 (iii) and 7 (vi)] [Also in Group XXVIII] Fuel is supplied from a metering device M, Fig. 19, through a pipe 90 feeding a number of injectors 26 each comprising a plunger 27 which is raised by a spring to open a port 34 allowing fuel to enter the space 29 into which air is forced on the compression stroke, and shortly before the end of compression a cam actuates the plunger 27 to inject the mixture through holes 31. The device is shown applied to a 12-cylinder engine wherein separate metering devices M, Ma each feed through a pipe 90 six injectors 26, the plungers 27 of which are actuated so that the times of opening of the ports 34 of each set of cylinders do not overlap. A low-pressure pump 49 with a return by-pass valve 62, supplies fuel from a tank to a float-chamber 56 from which fuel is fed by a highpressure pump 50, with a by-pass valve 76, through a pipe 70, and filter 72 to a surge chamber 73 connected by pipes 83, 83a to the metering devices M, Ma, each of which comprises a reciprocating valve 80 and metering pump 96, Figs. 3, 19. When a groove 81 on the valve 80 opens a port 84, fuel flows from the pipe 83 through a pipe 92 to the pump space 108, Fig. 17, from which the fuel is forced on reciprocation of a plunger 97 through a pipe 109, Fig. 19, communication of which with the pipe 90 feeding the injectors is controlled by a second groove 82 on the valve 80. The amount of fuel injected is controlled by varying the position of a valve 102, Fig. 17. having a groove 103, connected by ports 104 to the interior of plunger 97, through which fuel is spilled until the plunger 97 closes the groove 103. The valve 102 is controlled by a lever 122, Fig. 3, actuated by a centrifugal governor 115 and by a manual control. The lever 122 is rotatably mounted on a short eccentric shaft 1212, which is rotatable by a hand or foot actuated linkage, and the inner end thereof fits into a recess in a co-axial shaft 121 rotatable by the governor 115 and carrying a projection 1213 which engages an arm on the lever 122. On an increase of speed the shaft 121 is rotated anticlockwise and the valve 102 is raised by a spring 105 to reduce the amount of fuel delivered per stroke of the pump 95, rotation of the shaft 1212 by the manual control varying the fuel supply independently of the governor. The metering valve 102a supplying the other injectors is controlled by a lever 122a which is adjusted conjointly with the lever 122. The valves 80, 80a and pump plungers 97, 97a are reciprocated by cams 85, 85a, 99, 99a on a shaft 45 which also drives through a bevel gear 114 the governor 115, and through a gear 47 the pumps 49, 50. Any leakage past the injector plungers 27 escapes through passages 134, Fig. 19, to common return pipe 136 leading to the float chamber 56, and a manual shut-off valve 130 in the fuel delivery pipe of each injector enables faulty injectors to be traced.

Title: Improvements in bonding textile materials
IPC: D04H11/00
Filed: 1947-02-21
Abstract: Textile material is bonded to a surface by providing the latter with a sticky coating of a thermoplastic polymer and a mixture of two plasticizers therefor of substantially different volatilities, applying the textile material to the coating so that it adheres thereto, and causing preferential evaporation of the more volatile plasticizer, thereby causing the coating to become non-sticky.  As the thermoplastic polymer, polyvinyl acetate and other oxygen-containing vinyl polymers such as the polyvinyl acetals and partial acetals, or polyacrylic or polymethacrylic esters, may be used, as well as copolymers of two or more unsaturated monomers or mixtures of two or more compatible polymers.  Vinyl chloride polymers should only be used if of relatively low molecular weight or if containing substantial proportions of a copolymerized monomer such as vinyl acetate or other vinyl ester, or an ester of maleic acid or acrylic acid, or a vinyl alkyl ketone.  As the more volatile plasticizer, dimethyl phthalate, glycol diacetate, triethyl phosphate, tributyl phosphate, triacetin, triethyl citrate and other plasticizers of comparable volatility at temperatures between 100 DEG and 150 DEG  C. may be used, and as the less volatile plasticizer, tricresyl or triphenyl phosphate.  The polymer composition may be applied from a solution in a volatile solvent, such as acetone, or if a cellulose acetate fabric is used, a mixture of methyl ethyl ketone and methyl isobutyl ketone, which is evaporated before applying the textile material.  The latter may be flock of regenerated cellulose, cellulose acetate or other water-insoluble fibre-forming cellulose derivative, cotton, silk, nylon, polyethylene terephthalate, polyvinyl chlorideacetate, or a copolymer of vinylidene chloride with vinyl chloride or of acrylonitrile with vinyl chloride or methacrylonitrile.  The fabric base may be cotton, regenerated cellulose, or high tenacity regenerated cellulose.

Abstract: 539,370. Wireless receiving sets. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. March 20, 1940, Nos. 5213 and 8461. [Class 40 (v)] [Also in Group XXXVI] The dial or like lamp of a wireless receiving-set adapted for use on A.C. or D.C. mains is so connected in the supply circuit that it is traversed both by the cathode-heater current and by the output current of the supply rectifier. As shown the lamp L is connected on the earthed side of the supply mains W between the " earth " terminals of the condensers C<SP>1</SP>, C2, which in association with a choke M smooth the output of the rectifier S. The heater current passes through a barretter B and the heaters H to the earth side of the lamp and through the lamp to the other mains terminal. By this means the lamp current is substantially the same whether the set is connected to A.C. or D.C. mains. More perfect equality may be obtained by connecting variable resistances between the lower plate of the condenser C<SP>1</SP> and the opposite terminals of the lamp, or by connecting a condenser of suitable capacity between the upper plate of condenser C<SP>1</SP> and the lower plate of condenser C<SP>2</SP>.

Title: Digital carrier wave detector
IPC: H04L1/20
Filed: 1977-02-09
Abstract: 1518642 A.C. systems INTERNATIONAL BUSINESS MACHINES CORP 9 Feb 1977 [3 March 1976] 05242/77 Heading H4P A carrier wave detector provides a signal indicating a detected carrier in response to the detection of a preponderance, of carrier transitions (frequency or phase) within predetermined time bands encompassing the expected transition instants of digital data received, as compared with such transitions occurring outside the bands. Counter 260 is enabled to count up by unity for each detected received signal transition which lies within the bands, the bands being defined by counter 230, to predetermined stages of which are connected AND gates 242, 244, 246, 248, controlling flip-flop 258, enabling counter 260 to count up, only should it receive counting pulses when the content of counter 230 lies within either of two ranges corresponding to the bands, the extent of the bands being set in relation to the expected quality of the incoming channel. Otherwise counter 260 is enabled to count down by two for each received transition outside the bands. Counter 260 provides a carrier detect output at 92', as soon as its content reaches 2<SP>n-1</SP> the counter capicity being 2<SP>n-1</SP>. In normal use, the content may attain the maximum value, and short bursts of noise or faulty reception will not cause the carrier detect signal to be removed, unless the count-reaches 2<SP>n-1</SP> again. The carrier wave detector is incorporated in a digital receiver, Fig. 1 (not shown), which is squelched unless the carrier detect signal is present. The receiver operates by setting counter (40) to half its capacity at the beginning of a bit duration, the counter, clocked at a high rate, reaching either its greatest (for "0") or at least (for "1") content prior to the end of a bit duration, whence its content corresponds to the received bit, prior to being reset for the next bit.
