Abstract: 458,752. Valve gear; fuel pumps. KIPFER, P., 62, Avenue des Ortolans, Boitsfort, Brussels. May 24, 1935, No. 15250. Convention date, May 24, 1934. [Classes 7 (iii) and 7 (vi)] Reciprocating or oscillating valves are actuated by a slide member or strap surrounding an eccentric member which in turn surrounds another eccentric or crank on the valveactuating shaft. Fig. 2 shows an eccentric disc C<1> secured to a valve-actuating shaft D<1> and surrounded bv an eccentric disc 3 enclosed by a strap having an extension connected at E<1> to a link 5 attached at F<1> to the valve. The housing 2 is preferably made in two halves secured together by bolts G and the pin E<1>, but may be in one piece which is then slotted at each end of a diameter to allow the disc 3 to be inserted edgeways and then moved through 90‹ into its proper position within the housing. The eccentric may be replaced by a cranked shaft. The bearing surface B<1> between the disc 3 and housing 2 may be of spherical form, and the disc 3 may be of bronze or light alloys, or of steel with a thin coating of white metal. Fig. 5 shows another form in which the disc 3 actuated by a crank C<1> is surrounded by a slide member F<1> which reciprocates in guides and may be directly connected to the valve. Fig. 11 represents an engine with two rows of cylinders, the valves of which are actuated from a shaft D provided with eccentric-actuated discs 3, arranged on opposite sides of the shaft bearings J. As shown, the discs 3 of the two adjacent cylinders of one row may be at opposite sides of one bearing J, and the discs 3 of two adjacent cylinders be at opposite sides of the next bearing ; or the valve drive for the cylinder of one row may be followed in the direction of the shaft by the valve drive for a cylinder of the other row. Again, the valves may be actuated from an overhead shaft D, Fig. 13, which may also actuate the fuel pumps Y, and in this case the valve drives 3 may be at opposite sides of one bearing J and the fuel-pump drives at opposite sides of the next bearing as shown, or the valve and pump drives may alternate along the shaft. In some cases, the main crank-shaft may serve as the valve-actuating shaft.

Title: Bulking yarn
IPC: D02G1/02
Filed: 1960-05-03
Abstract: 948,773. Finishing yarns. CELANESE CORPORATION OF AMERICA. May 3, 1960 [May 12, 1959], No. 15520/60. Headings D1F and D1W. Twisted or untwisted yarn as a monofilament or composed of continuous filaments e.g. of cellulose acetate or triacetate,nylon or polyethylene terephthalate, is bulked by passing it through a cylindrical chamber from one end to the other while a stream of heated setting fluid e.g. steam, under pressure is fed tangentially into the chamber in a direction transverse to the direction of yarn travel so as to flow through it as a vertical stream (the direction of which in the vortex may oppose that of the twist in the yarn) to twist the yarn and simultaneously set the twist. The yarn is fed through the point of false-twist and bulked yarn is taken-up at overfeed and draw down ratios both preferably greater than unity. In the finished yarn, which is taken-up with or without twist, individual filaments are helically crimped with the lightness of the helix varying individually along each filament, and the filaments are not in registry so that the yarn resists stretch. Two or more yarns, which may differ in denier and/or direction of twist, may be bulked together to form a composite yarn. The jet shown in Fig. 2 provides off-set yarn inlet and outlet passages 22a and 26 (in a longitudinally adjustable tube 22 and a plug 25) communicating with a chamber 27 to which steam is fed through a bore 32. The jet of Fig. 4 provides axially adjustable, aligned yarn inlet and venturi outlet passageways 41 and 48 meeting in a chamber 49 to which steam is supplied through bores 54 and 35. Specification 776,410 is referred to.

Abstract: 925,576. Measuring electrically. LEAR Inc. May 1, 1961 [May 11, 1960], No. 15620/61. Class 40 (1). In a selsyn system wherein the receiver rotor 24 (Fig. 1) is driven to a null position by a servomotor 28, an additional perpendicular rotor winding 22 is simultaneously driven to its maximum voltage position, and the voltages on the two rotors 22, 24 are compared via rectifier bridges 30, 32 to operate an alarm 36 when the voltage in 22 decreases, or the voltage in 24 increases. In an embodiment for comparing the readings of three flux valve compasses 40a, 40b, 40c (Fig. 2), the magnetic field distribution is transferred to a selsyn 48 to produce an error signal in winding 52 which is amplified at 54 to control a torquing device 56 on the leveling axis of a gyroscope 58, causing it to precess about its azimuth axis, by an angle which is transmitted by selsyn 60 to selsyn 62, the voltage in rotor 66 being fed to motor 70 which drives the rotor 66 to its null position, thereby producing on the compass card an indication of the heading of the supporting vehicle. The angular position of motor 70a is compared with that of 70b by selsyn link 72a, 88. If the two angular positions agree, perpendicular rotors 92, 94 have maximum and minimum voltages induced in them, and any deviation from this condition produces an alarm indication. Similarly, the angular positions of motors 70c, 70b are compared by selsyn link 72c, 80 and produces an alarm indication when they do not agree.

Abstract: 1312942 Releasable fastenings M NICOLA and E LUCIANO 2 April 1970 [2 April 1970] 15754/70 Heading E2A [Also in Divisions G4 H1 and H2] In a key-operated switching device for controlling an electrical latch on a door or a safe or for controlling a vehicle, the key 22 comprises an insulating body 20 carrying a plurality of contacts 31..39 connected in a predetermined manner and cooperating with a socket 41 having blocking means 42 defining first and second positions for the key 22 in the socket 41, the electrical connections made to the contacts 31..39 being different in the first and second positions such that in the first position a door is capable of being opened and an alarm circuit rendered inoperative whilst in the second position the door is locked and an alarm circuit is capable of being operative. As described, the first position is defined by a recess 40 in key 22 being engaged by a spring 42 in the socket 41 so that contacts 31..38 are respectively engaged by contacts 1a..8a, while the first position is defined by full insertion of the key 22 so that contacts 9a, 10a are additionally bridged by contact 39. Identibcation of correct key. In the particular key shown, contacts 31, 36, 37 and 38 are joined by a printed circuit, whilst contacts 32..35 are isolated. Fig. 4 shows a logic system for operating the lock-controlling relay RL2 and the alarm relay RL1. The circuit receives power from a battery connected between terminals F and H only if contacts 9 and 10 on the socket 31 are bridged by a contact 39 when the key 20 is in its fully home position or if relay RL2 is energised by a bistable pair of transistors Tr8, Tr9. Transistor Tr1 and diodes D1..D3 sense the key presence by supplying a "1" at A when the key is inserted. Transistor Tr2 and diodes D5..D7 supply a "1" at B if the correct contacts (36, 37, 38) are connected together. Transistor Tr3 supplies a "0" at C when one of the isolated contacts 32..35 are connected. The three logic signals at A, B, C turn on transistor Tr5 which inhibits Tr4 and thus prevents operation of the alarm relay RL1, but the insertion of an incorrect key or the opening of door switches connected at L will set off the alarm by energising RL1, which is then held energised by feedback via Tr7 and D9 but may be released by the insertion of the correct key. Locking door and setting alarm. The door is locked by inserting the key 20 fully into the socket 41 and then withdrawing the key, this action allowing a pulse from signal B to be passed via a capacitor M to set bistable Tr8, Tr9 so that RL2 is energised, contacts 47 of which retain the power to the logic circuit when the key is withdrawn. Unlocking door and inhibiting alarm. The lock is released and the alarm inhibited by insertion of the key into the first position (up to the stop 42) when bistable Tr8, Tr9 will be reset, releasing RL2. Modifications. The key may operate further devices by rotary movement. In a car, circuit G may break the supply to the ignition coil when the alarm is set.

Title: Improvements in or relating to high frequency electronic valve amplifiers
IPC: H03F1/07
Filed: 1947-06-17
Abstract: 637,877. Modulating systems. SOC. INDEPENDANTE DE TELEGRAPHIE SANS FIL. June 17, 1947, No. 15974. Convention date, Aug. 12, 1946. [Class 40 (v)] In a modulated amplifier of the type in which two output valves operate in phase quadrature at carrier frequency, modulation is applied to the output valves and to a driver valve such that during the negative modulation half-cycle the driver valve only is modulated and one of the output valves is quiescent and during the positive half-cycle the output valves only are modulated, the quiescent valve becoming operative. As shown, a driver valve 10 fed with unmodulated carrier energy supplies two output valves 1, 2 whose grids are coupled through a 90 degree phase-changing network 7, 8, 9 and whose anodes are coupled through an impedance inverting network 3, 4, 5 and supply a load 17. A class B modulator valve 11 modulates the screen grid and anode potentials of the driver and two further class B cathode follower modulators 12, 13 fed from modulating source BF in antiphase to valve 11 modulate the suppressor potentials of valves 2 and 1 respectively. The biassing potentials from source 15, 16 are arranged such that in the absence of modulation, valves 10 and 1 act simply as amplifiers and valve 2 is quiescent. During the negative modulation half-cycle valve 11 modulates the output of valve 10 and since modulator valve 11 is substantially biassed to cut off, valve 1 still acts as an amplifier. On the positive half-cycle valve 10 acts as an amplifier and valves 1 and 2 receive the modulation. At modulation peaks valves 1 and 2 deliver equal power to the load. To avoid non- linearity at the junction of the two half-cycles impedances 18, 20 and 19, 21 are provided in the cathode and screen grid leads respectively of valve 1 to produce non-linear negative-feedback at modulation frequencies. Alternatively modulation of the driver may extend into the positive half-cycle.
