Title: Improvements in or relating to spinning pumps
IPC: F04C2/14
Filed: 1929-10-03
Abstract: 331,152. Barmer Maschinenfabrik Akt.-Ges., and Sieper, F. Oct. 3, 1929. Governing and regulating pumps; movable-abutment type.-A rotary measuring pump for artificial silk spinning has the pressures in its inlet and outlet chambers maintained at the same level by means of an automatic throttling device. A diaphragm 5 separates two annular areas 7 and 6 which are connected to the supply chamber of the pump, 17 and 18, and the discharge chamber respectively. An excess of pressure on the supply side causes the diaphragm to deflect and throttle the discharged material which passes through a duct 16. The annular space 7 is inclined at an angle to the face of the plate 2 to prevent the material from shortcircuiting from the inlet duct to the exit duct, both of which are situated in the narrow position of the space 7. Specifications 182,154 and 293,325 are referred to.

Title: Arrangement for producing relaxation oscillations, more particularly for television purposes
IPC: H03K6/02
Filed: 1933-10-30
Abstract: 429,427. Generating circuits employing gas-discharge tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Oct. 30, 1933, No. 30041. Convention date, Nov. 4, 1932. [Classes 40 (iii) and 40 (v)] In a relaxation oscillator for television, interfering potentials are prevented from reaching the grids of gas-discharge tubes 1, 2. The conductors are screened by an enclosing tube and the bulb of the discharge tube is metallized and connected to earth. The discharge tube is indirectly heated, the centre of the heating-source is connected to earth, and the heating-filament is screened from the discharge space by the equipotential emitting surface. The grid of the tube 1, producing the line-control frequency, is connected to earth through a choke 28 or a tuned circuit with a small impedance at the mains and adjacent low frequencies, but a large impedance at the line frequency and its harmonics. The choke is screened and its leads made as short as possible. The charging currents in the line-frequency oscillator and the image-frequency oscillator are smoothed by filters 30 .. 33. Resistances 7, 8 for stabilizing the frequencies can be adjusted by an external control to a limited extent. The output circuit 24, 22 of the line-control oscillator has such a small time constant that it does not transmit effectively frequencies below the line frequency, and in the output of the image-control oscillator a filter 26, 27 prevents the passage of higher frequencies of the order of the line frequency. Reference has been directed by the Comptroller to Specification 422,963.

Title: Process for the manufacture of condensation products
IPC: C08G75/16
Filed: 1934-10-19
Abstract: Condensation products containing sulphur are obtained by treating low-molecular aliphatic alcohols or ethers which contain at least two halogen atoms linked to different carbon atoms, or if the ether group is an ethylene oxide linkage, which contain at least one halogen atom, with a polysulphide, for example the di-, tri- or tetrasulphides of the alkalis, alkaline earths, or ammonia, if desired in a solvent such as an aqueous medium, and with the addition of alkali iodide or organic bases or other additions to modify the reaction.  The products which are viscous or plastic to hard, may be after-treated with heating and filling or vulcanizing agents.  They are nearly odourless.  According to examples: b -b <1>-dichloroethylether, a -b -dichloroethylether, sym - dichloromethylether, glycerine dichlorohydrin, and epichlorohydrin are heated at temperatures up to 100 DEG  C. with polysulphides of sodium to give light-coloured plastic or hard products, some of which are aftertreated with heat, or fillers such as zinc oxide, and thiuram disulphide to give faktis- or rubber-like products.  The use of dichlorohydrin, halogen derivatives of di- or polyglycerines, and b -b <1>-dichloropropylether is also specified.  The Specification as open to inspection under Sect. 91 refers to the treatment of as-dichlormethylether.  This subject-matter does not appear in the Specification as accepted.

Title: Control for a vehicle
IPC: H02P5/68
Filed: 1965-07-15
Abstract: 1,046,385. Differential driving. CLARK EQUIPMENT CO. July 15, 1965 [Dec. 28, 1964], No. 30112/65. Heading B7H. [Also in Division H2] A fork-lift truck, having a non-powered dirigible rear wheel and a pair of non-steering front drive wheels, is moved forwardly by actuating switch 116 to close contact 192. Foot-pedal 36 is depressed to allow plunger 96 to close contact 98, further movement of the plunger being prevented by latch 208. Relays 198, 200, close contacts 150, 174, whereby drive motors 48, 52, are connected in series with resistors 66, 68. Coil 220 is energized so that latch 208 disengages plunger 96. Further depression of pedal 36 sequentially removes resistors 66, 68 and then connects the motors in parallel. When the dirigible wheel is turned by more than 30 degrees from a central position, the motor coupled to the inside drive wheel is de-energized. Thus, such turning of the rear wheel may actuate cam switch 132 to energize relay 90 and prevent energization of relay 92. This opens contact 78 and closed contact 82, whereby motor 48 is energized and motor 52 is de-energized. If the truck is being driven forwardly with switches 98, 100, closed, and an attempt to reverse the truck is made, both motors are de-energized and cannot be reenergized until switch 98 is opened. Thus, the pedal must be released. Continued coasting of the truck energizes coil 220 so that latch 208 allows the plunger to be moved only so far as to close switch 98. The two motors are then connected in series with resistors 66, 68, across the battery for reverse-current braking at the first speed step. As the motors begin to drive in the opposite direction, the current in coil 220 is reversed to release the plunger 96. The coil 220 may be connected in parallel with either armature 48 or 52 so that the anti-plugging mechanism is effective whether both or only one of the motors is energized.

Title: Method of manufacturing pipes of plastic material
Filed: 1959-09-09
Abstract: 855,277. Making reinforced pipes. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 9, 1959 [Sept. 18, 1958], No. 30749/59. Class 99(2). In a method of manufacturing pipes from hardenable plastic material reinforced with a fibrous material e.g. glass fibre, the two materials are applied on to a mandrel which consists of a tightly wound helix of thread of rectangular cross section, the plastic material being subsequently hardened by heating and the helix removed by stretching it to reduce its transverse dimension. The helix may be applied around a rotating smooth rod or form by itself a non-rotating mandrel. As shown, a bundle of glass fibres 1 is guided by rolls 3 through a bath of plastic material 4, the fibre bundles being evenly distributed, by means of a disc 5 around the mandrel 10. The mandrel and the fibre bundles are then drawn through a mouth piece 7 but are first provided with a braiding of glass yarn from spools 6. Surplus plastic material passes to container 4 after being pressed through the braiding, whilst the mandrel and surrounding plastic pipe is passed through an oven 8 wherein the plastic material is hardened.

Abstract: 1478633 Keyboards with coded outputs OMRON TATEISI ELECTRONICS CO 11 July 1974 [18 July 1973] 30755/74 Heading G4H Information input apparatus (e.g. for a calculator or a cash register) comprises means TM for producing first relatively long timing signals T1-T6 and feeding them sequentially to different gating circuits NA1-NA6, means for producing second relatively short timing signals t4 (one during each of T1-T6) and feeding them simultaneously to NA1-NA6; and a plurality of information input switches K1-K15 each associated with at least one of the gating circuits, each circuit in combination with its associated switch or switches producing a logic output signal b1-b6 indicating whether or not an associated switch is actuated during the periods when the circuit receives the first and second signals. It is stated that the use of signal t4 results in reduced power dissipation caused by circuit operation, and is an improvement over the keyboard disclosed in Specification 1,415,469 (Figs. 1-4, not shown). In the embodiments of Fig. 5 and Fig. 8 (not shown), each key is associated with two gating circuits; in the embodiment of Fig 10 (not shown) it is associated with one circuit. In the embodiment shown, when no key is depressed NAND gate NG produces a "1" level signal; depression of, e.g., K1 connects lines R1 and R2 to produce extra pulses on these lines (dotted-line pulses in b1 and b2), giving rise to signal K1 from NG. The presence of signals t4 (each of which occurs for only a small part of the period of timing signals T) ensures that the subsequent circuitry is actuated for a shorter time than if these pulses were absent (since the output of NG would then depend on the period of signals T). The pulse signal K is fed via a holding circuit HLD to a MOSFET decoder matrix DC, Fig. 6A (not shown) which outputs a signal on one of fifteen lines to indicate the depressed key.
