Title: Improvements in starting arrangements for electric generators driven by internal combustion engines and associated with accumulators
IPC: F02N11/08
Filed: 1940-04-02
Abstract: 543,486. Starting prime movers ; self-contained supply systems. PORSCHE, F. April 2, 1940, No. 5935. Convention date, March 9, 1939. [Class 38 (iv)] Variable speed generators, with.-An electrical system for automobiles has an electromagnetic switch for the starter motor circuit combined with the reverse current cut-out and the arrangement is such that manual operation of a starter switch cannot effect closure of the electromagnetic switch so long as the reverse current cut-out is closed. The contacts of the electromagnetic switch may be manually closed by a press-button extending from the enclosing casing of the reverse-current cut-out so facilitating control from the vicinity of the engine. A combined voltage regulator and reverse current cut-out shown in the Figure. The armature 4 of the cut-out is held against vibration after closing by a current coil 8 and auxiliary armature 7 on a rod 6. This rod couples the main armature 4 and a spring blade 19 carrying one contact 18 of the electromagnetic starting switch so that this contact may be carried beyond the range of the other contact 17, which is operated by a coil 14 and armature 15, when a manual switch 13 is closed. The coil 14 may be arranged on the core of the reverse current cut-out or voltage regulator. The switch 13 is in parallel with the usual " charging indicator lamp 11 and is connected in series with the coil 14 between positive poles of generator 1 and battery 2. The spring blade carrying contact 17 may be manually actuated by a button 26 and rod 25. A stop 23 defines the range of movement of the contact 1. A stop 22 determines the position of a spring 21 which applies the full restoring force to the cut-out armature after permitting movement of contact 18 under the lighter yoke of the spring 19 to render the starter inoperable at a low engine speed.

Title: Improvements in secret signalling systems
IPC: H04B10/532
Filed: 1940-04-03
Abstract: 579,726. Signalling by luminous signals. BRITISH THOMSON-HOUSTON CO., Ltd., and MILNER, C. J. April 3, 1940, No. 5975. [Class 118 (ii)] A secret signalling system comprises polarizing screens interposed at spaced points in a beam of light, means for adjusting the angular position of the screens in relation to the axis of the beam whereby the beam is capable of being obturated in different positions of the screens, and means for indicating a number of different screen positions for the purpose of transmitting signals. Preferably a two-way system is used in which oppositely-directed parallel beams of light are produced by light sources 1, 1<1> and mirrors 2, 2<1> and are received by viewing-tubes 5, 5<1>. Polarizing screens 3, 3<1> and 4, 4<1> are interposed in the beams, one screen being arranged near each source of light and another adjacent to a viewing-tube. In use, an operator sets the screen 3 to a given angular position and the receiver sets the screen 4 to a point at which the light is obscured. A pointer moving over a scale bearing indicia to be transmitted is attached to the screen 3, and a corresponding pointer and scale are associated with the screen 4 to give an indication, when the light is obscured, of the signal transmitted. Preferably the screens 3, 4<1> and 3', 4 are coupled together by a pinion engaging a third pinion 7, Fig. 2, provided with a pointer 9 moving over a fixed scale 10 of indicia. The screens 3<1>, 4<1> are arranged with their polarizing planes at right angles to those of the screens 4, 3, respectively. Thus when the receiver turns the screen 4 to observe the beam of light, the screen 3<1> is correspondingly rotated and the transmitter, looking through the tube 5', sees the parallel beam obscured and knows that his signal has been received correctly.

Title: Improvements in or relating to fuel injectors for internal combustion engines
IPC: F02M61/14
Filed: 1939-02-24
Abstract: 525,630. Fuel-injectors. BOSCH GES., R. Feb. 24, 1939, No. 6125. Convention date, Feb. 25, 1938. [Class 7 (iii)] To prevent angular displacement of the components of a fuel injector, the components are held together by a sleeve having fine teeth which intermesh with fine teeth on one of the components. As shown, the components consist of a nipple 12 screwed into a nozzle cap 4 which contains the guide 1 for the fuel valve 2. The sleeve 18 is provided with fine teeth 20 which can be slid along fine grooves 19 in the nipple until projections 17 on the sleeve enter recesses 16 in the cap 4. The sleeve is retained around the nipple 12 during transit or assembly of the injector by a spring retaining ring 21. A filter 13 is disposed inside the nipple to which the fuel feed pipe 14 is attached. The cap 4 is pressed against a conical seating 9 in the cylinder head by a gland nut 28 which bears against the sleeve and screws into a sleeve 24 screwed into the head. A pin which extends into a groove 10 in the cap 4 prevents angular displacement of the cap in the cylinder head.

Title: Improvements relating to driving means for pumps
IPC: F04B49/12
Filed: 1928-02-28
Abstract: 312,596. Grant, C. A. Feb. 28, 1928. Actuating by liquid pressure; stroke, varying.- Apparatus for driving reciprocating pumps with variable stroke from a source of varying power, such as a windmill, comprises a closed cylinder 1 containing a liquid, and an inner cylinder 5 communicating with the cylinder 1 by ports 7, and containing a piston &c. 15 which is connected by a rod 18 to the windmill &c. The rod carries a nut 29 engaging a crosshead 28 connected by rods 27 and a crosshead 20 to the rod 19 of the pump to be driven. During the upstroke of the rod 18, if the power of the windmill is low, the liquid displaced by the piston &c. 15 escapes through a hole 13 in a small piston 10 and through ports 14 in the hollow rod of this piston, to the cylinder 1. If the windmill &c. speeds up, the piston 15 moves faster, and the liquid displaced by it, being unable to escape fast enough through the port 13, raises the piston 10 at a greater speed than the speed of the piston 15, and, by means of its rod 11, imparts the same movement to the cross-head 28 and thus increases the stroke of the rod 19. During the downstroke, which is effected by gravity, liquid in the cylinder 5 passes up through a valve 17 in the piston 15. In another form, the port 13 in the piston 10 is throttled by a lift valve when the speed of the piston 15 increases. In another form, Fig. 4a, the power rod 56 is connected to the pump rod 49 by a cylinder 45 attached to a piston 44 slidable in a fixed cylinder 41. The rod 49 passes through the piston 44 and carries a collar 52 and a piston 51 which works with clearance in the cylinder 45. When the power of the windmill is low the liquid raised by the pump passes through valves 47 in the piston 44, through ports 53 in the cylinder 45, past the piston 51, and through ports 54 to the delivery chamber 37. When the windmill speeds up, the liquid cannot escape past the piston 51 fast enough, and this piston is moved by the liquid relatively to the cylinder 45 and increases the stroke of the rod 49.

Title: Improvements relating to the manufacture of rings
IPC: B21D53/16
Filed: 1942-05-11
Abstract: 550,938. Making finger rings. DAW, H. S May 11, 1942, No. 6347. [Classes 83 (ii) and 83 (iii)] Finger rings are made from rods or tubes of gold, platinum or silver by machining operations in closed boxes, with observation panels that collect all the cuttings without loss. When using a solid rod 1 the rings are parted by a series of parallel cuts 3 leaving a series of discs connected by a small core 4. These are broken off as required and mounted in a chuck whilst the centre is removed by an annular cut 5. The square section rings may be mounted on a wooden mandrel for profiling or the parting tool may be combined with a form cutter so that D-section rings are produced without a separate profiling operation. When tubular stock is used the rings are produced by the single combined parting and forming operation. The box 9 for surrounding the work in the lathe during the first operation has a rib 28 for clamping and is otherwise formed to fit the slide-rest. The lid 10 has an inclined top 11 with a window 12. The holes 15 are larger than the rod diameter to permit the feed of the slide and are closed by sliding toggle plates 16 that are an exact fit for the rod. The tool enters the box through a slit rubbercurtain 13. The box for the second operation has a hole at one side and this is closed by a rubber diaphragm, slit to admit the chuck.

Filed: 1963-02-19
Abstract: 1,029,791. Position finding using electromagnetic waves. ETABS. MERLIN, and GERIN S.A. Feb. 19, 1963 [Feb. 26, 1962], No. 6599/63. Heading H4D. [Also in Division G1] The distance D between two objects, e.g. travelling bridges P 1  and P 2 , Fig. 1, constrained to move in one direction, e.g. along rails R 1  and R 2 , is determined by an arrangement comprising a source of electromagnetic energy E, mounted on one of the objects P 1 , and a receiving means R, displaced by a distance d laterally from the parallel of movement passing through the source E, and comprisingtwo electromagnetic energy receptors, having overlapping directivity lobes C 1  and C 2 , the receiving means being on the object P 2 , Fig. 1, or with energy reflecting means M, Fig. 2 (not shown), on the object P 2 , on the object P 1 , a virtual source E<SP>1</SP> being formed. The arrangement is such that the relative strengths S 1  and S 2  of the signals detected by the two receptors, defines the angle Q, and hence the distance D. The electromagnetic energy may be radio energy in which case the receptors are radio antennas comprising a common parabolic reflector with two slotted antennas at the focus thereof or it may be infra-red energy in which case the receptors are two photo-cells A 1 , A 2 , Fig. 3 (not shown), mounted at right-angles, to each other and having directivity lobes C 1  and C 2 . In the radio energy case in which the source and receiver are on different objects, the radio signal may be modulated with a telephone signal to allow the operators of the two objects to communicate. The radio wave is received by each antenna and detected. The resulting low-frequency signal is amplified and further detected to produce a D.C. signal proportional to S 1  or S 2 . The two D.C. signals are passed to logarithmic circuits which produce signals proportional to log S 1  and log S 2 , which signals are used to energize a differential indicating means which gives an indication proportional to log S 1 /S 2  and related to O and R. Signalling devices may be actuated to give distinctive warnings as the distance between the two objects becomes equal to given limits. Release mechanisms may also be controlled according to the distance D. The equality axis of the two lobes is adjusted to coincide with the average direction of the incoming waves.
