Title: Improvements relating to rotary wing aircraft
Inventor: SISSINGH GERHARD JACOBUS
IPC: B64C1/00
Filed: 1948-06-03
Abstract: 675,657. Helicopters. NATIONAL RESEARCH DEVELOPMENT CORPORATION May 30, 1949 [June 3, 1948; June 3, 1948], Nos. 14988/48 and 14989/48. Class 4. A stabilizing means for a rotary wing aircraft comprises two or more independently pivotable gyratory stabilising members which are respectively damped so as to respond at different rates to displacements of the aircraft and are arranged to provide reference planes in relation to which the orientation of the main rotor disc may be automatically adjusted. The main rotor 10, 11 is mounted on a drive shaft 8 and is arranged for cyclical pitch change of the blades by means of a swash plate 9 coupled by a link 15 to one end of an arm 12 which is pivotally connected to links 13, 14 attached respectively to arms 1, 2 mounted on the drive shaft 8 and free to pivot about an axis 6-6. Masses 3, 4 arc attached to the extremities of the respective arms 1, 2 which have equal moments of inertia and are damped by hydraulic dampers 18, 19 in such a manner that the bar 1 is more heavily damped than the bar2. Since the bar 1. is responsive to the rate of change of attitude of the aircraft and the bar 2 is in appreciable measure responsive to both change of attitude and rate of change of attitude, in the resultant control effect upon the swashplate 9, the bar 1 counteracts the excessive component of control displacement proportional to the rate of change of attitude achieved by the less heavily damped bar 2. Damping of the arms 1, 2 may be achieved aerodynamically, Fig. 2 (not shown), by dispensing with the hydraulic dampers 13, 19 and replacing the masses 3, 4 by upper auxiliary rotor blades of which the blades of the upper bar 1 are larger than those of the lower bar 2. Servo control of the pitch of the blades of the main rotor 10, 11 may be achieved by making the blades of the bar 1 adjustable in pitch and connecting them to a pilot's control member so that change of pitch of the blades of the bar 1 causes the bar to rock on the axis 6-6 to effect cyclical control of the main rotor blades. In a further arrangement, Fig. 3 (not shown), the aerodynamically damped bars 1, 2 are not mounted on a common axis but are placed one above the other and positioned at right angles to one another in parallel spaced planes and so interconnected that pitch change of the blades of one bar is damped by flapping displacement of the other bar. In a still further arrangement of vertically spaced control members, Fig. 4 (not shown), the blades of the lower bar may be replaced by masses located at the extremities of the bar, which is provided with a hydraulic damper.

Title: Toy gun with shell ejection
IPC: A63H5/04
Filed: 1960-04-28
Abstract: 875,093. Toy guns. MARX & CO. Ltd;, LOUIS. April 28; 1960 [Feb; 4,1960], No. 15024/60. Class 132(3).  A toy machine gun, actuated by a spring, simulates the expulsion of used shells from a magazine, produces a noise and simulates recoil. As shown, a gun actuated by a spring 16 has a magazine 22 at one side extending longitudinally of the gun, a noise producer comprising a clapper 42, Fig. 3, which can be bowed and then allowed to snap back against a diaphragm 40, and a muzzle portion 70 which can reciprocate to simulate recoil. The actuating spring 16 is tensioned by retracting a pusher 30 extending through slots 34, 32, Fig. 5, in the side of the gun and magazine and, with the pusher in the retracted position, shells can be fed into the magazine through a port 24 and past a leaf spring 28, Fig. 4. As the pusher moves forward under trigger control it pushes the shells forward, each shell in turn depressing the leaf spring and then being ejected upwards by it. At the same time, the spring 16 moves a rack 44 forward which, through a gear, turns a wheel 56, Fig. 1, having depending fingers 58, the fingers operating the clapper 42. The trigger 50 forms part of a spring urged slide 64 having a forward end 66 which moves into the path of the fingers 58. The rack also operates through gears a crank disc 76 which reciprocates the muzzle portion 70. To control the gun's firing rate there is a governor comprising an eccentric weight 88. The gun may be moulded from plastic material. A similar gun may be mounted on a tripod. Sights are shown in Fig. 1.

Abstract: 354,837. Moulding casein &c. by extrusion. ERINOID, Ltd. and LEGGAT, A., 58, Coleman Street, London. May 17, 1930, No. 15158. [Class 87 (ii).] Decorative patterned rods and tubes, of casein and like material, are formed by extrusion in an apparatus having a multiple-chambered head receiving various coloured ingredients in the separate compartments and forcing them through dies with alternate slit-like orifices connected to each compartment so that interleaved flat ribbons of different colour are delivered to a common mixing-chamber before they pass to the extrusion outlet. In the form illustrated in Figs. 1 and 2, the materials are delivered by worms through the pipes 8, 9 respectively to a die 13. Thin strips of one colour pass through the orifices 20, Fig. 2, in the die so as to alternate with similar strips of the other material passing through the slits 21. The strips are compressed in the chamber 16 into a multi-coloured rod which finally passes through the outlet die 17. The die 13 is clamped to a cylinder 2 by means of a conical-headed bolt 14 and the combined cylinder and die is clamped as a unit against the shoulder 18 by the nut 15. A core may be screwed on to the conical head of the bolt 14 for the production of tubes.

Title: High sensitivity electromagnetic relay
IPC: H01H47/00
Filed: 1944-08-09
Abstract: 590,179. Protective cut-out arrangements. URMENYI, L. Aug. 9, 1944, No. 15164. [Class 38 (v)] A high sensitivity relay, suitable for protecting measuring instruments, comprises a moving coil which, when energized sufficiently, connects a battery to the moving coil system, augmenting the current therethrough and thereby causing the relase of a biassed switch in the main circuit. In the adaptation of the relay of Specification 560,917, movement of a coil 3, in response to excess current, closes pin and wire contacts 38<2>, 39 or 38<1>, 40, according to the direction of the current, and connects a battery 31 to the coil 3 through a tapped resistance 44, contacts 47<1>, 47<2>, the metal base 56, and a spring 25, so augmenting the current in the coil 3. With the increased force, the spring 25 is overcome and a latch 22 releases a latch 51, releasing a spring-loaded switch spindle 13 (shown detached in the Figure for convenience of illustration), thereby opening main contact 34, 35 and battery contacts 47<2>, 47<1>, and closing contacts 50 to short-circuit the instrument G. Contacts 34, 35 are reclosed by pushing a knob 29, depression of which, beyond the normal closed position, permits spring 58 to close a contact 45, and test the battery 31 by means of the instrument G. Instead of using the resistance 44, one side of the battery may be connected to the mid-point of the coil 3 or a tapped battery may be connected across two fixed contacts, the coil being connected between the tapping and a single moving contact, through a resistance, Fig. 4 (not shown). The Provisional Specification states also that the moving coil may close a circuit including a battery and a separate electromagnet for opening the main switch.

Title: Improvements in or relating to automatic telephone systems
IPC: H04Q3/00
Filed: 1948-06-14
Abstract: 655,639. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 14, 1948, No. 16014. Convention date, June 13, 1947. [Class 40 (iv)] In a cross-bar system in which a call is set up by a marker over a plurality of cross-bar switches in series, individual setting of each switch by the marker is avoided, as also is undue unnecessary operation of the select magnets. As shown, Fig. 1, a marker seized in response to a call incoming over line L1, marks the wanted outgoing group L3 ... L4 by operation of R6 and also brings up R1 over the incoming b-wire. Availability of the trunks L3 ... L4 is indicated by the closure of contacts k 1  ... k 2 , each being connected to preference determining relays R8 ... R9 over contacts of the marking relay R6. If L3 is free R8 operates and short circuits its high resistance winding to bring up the select magnets SM31, SM11 in series. The latter connects the operating magnets BM31, BM11 to the relay R5 which causes these to operate on short circuiting its high resistance winding, and reverts a signal to release the marker. Relay R1 thereupon initiates release of all relays and magnets except the operating magnets which are held over circuits not shown. In a similar system in which connections are established over four cross-bar switches in series, Figs. 2, 3 (not shown), the select magnet of one switch is in series with a relay which prepares the circuit of the select magnet for the succeeding switch. When the latter select magnet is operated it shortcircuits the high resistance winding of the relay to operate the select magnet of the preceding switch.

In apparatus for carrying out chemical reactions in gases, vapours or finely dispersed solid or liquid substances by means of an electric glow discharge, the substances are introduced into the reaction chamber in the form of a jet and cathode rays are injected into the jet at its periphery. In Fig. 1, a glow discharge is formed on the inner surface of the ring anode 13, and generated electrons are directed radially into the jet 12. In Fig. 3, the glow discharge is formed on the interior of the rim 28 of nozzle body 24. A metal sleeve electrode 34 surrounds the rim 28 to leave a neutral gap 35. The nozzle body and the anode 37 have interior cooling ducts 25, 40. A.C. or D.C. may be used. Suitable voltages and frequencies are given and the speed of the jet may vary from one hundredth up to a multiple of the speed of sound. The anode 37 is slidable and an initial starting up procedure is described. The nozzle body and anode may be of metal or semiconductive material, e.g. germanium, silicon or sintered metal/non-metal, or of insulating material, e.g. ceramic or china or boron nitride, or coated with insulating material, e.g. a silicone lacquer. In a modification, Fig. 9 (not shown), the electrode 34 forms a second anode and the rim 28 is perforated, or two anodes may be provided, one adjacent the rim of the nozzle body. Further shield electrodes and neutral gaps may be provided in the nozzle structure, Fig. 7 (not shown). Preliminary ionization may be provided by establishing a glow discharge within a nozzle antechamber. In other modifications the anode 53, Fig. 5, is within a spherical electrode 52 which concentrates the charge carriers to a point on the axis of the jet. In Fig. 6, the nozzle aperture 65 is of spherical shape and in further modifications multiple nozzles may be used, the nozzle openings being parallel, converging or diverging and the anode provided with corresponding apertures, Figs. 8 to 12, 15, 16, 22 and 23 (all not shown). The nozzle openings may be radial, Fig. 14 (not shown), and may have various shapes such as shown in Fig. 17, 18 or 19, or may be annular, Fig. 20 (not shown).

Title: Improvements in or relating to electrical storage circuits comprising electric glow discharge tubes
Inventor: CROWTHER GERALD OFFLEY
IPC: G11C19/20
Filed: 1952-06-30
Abstract: 708,170. Digital electric calculating apparatus. MULLARD RADIO VALVE CO., Ltd. June 30, 1952, No. 16394/52. Class 106 (1). [Also in Group XL(c)] A storage circuit comprises a chain of cold cathode gas discharge tubes the anode of each of which is directly connected to high tension supply voltage and the cathode via a resistor to earth. The cathode of each tube is also connected via two resistors in series to the trigger electrode of the next tube of the chain and the junction of the resistors is connected to the high tension supply via a capacitor so that when the voltage of the supply is reduced sufficiently to extinguish all of the tubes and is then restored only those tubes ignite which were immediately preceded in the chain by a tube which was ignited prior to the reduction in voltage. Thus by sucsuccessive reductions of voltage the pattern of ignition of the tubes may be successively advanced along the chain. The Figure shows a storage chain comprising cold cathode tubes 1, 11, 21 connected in a chain which may be part of a closed loop. Each cathode is interconnected to the trigger electrode of the next tube in the chain so that if a tube is ignited then the voltage drop across its cathode resistor is such that when a negative pulse is applied to the H.T. + supply line 9 the voltage at the junction of the resistors 14, 15 or 24, 25 does not drop to such a low value as if the tube is non-conductive and on removal of the pulse the voltage exceeds the ignition voltage of the next tube in the chain, Fig. 2 (not shown). Thus each negative pulse applied to the H.T. + line advances the storage pattern of the tubes one stage. The tubes may all be rendered non-conductive by successive operations of switch 6 and information may be " written-in " to the chain by successive operations of switch 18. Specifications 663,574, [Group XL(c)], and 708,169, [Group XXXV], are referred to.
