Title: Mechanical toy
IPC: A63H18/04
Filed: 1949-06-09
Abstract: 643,567. Mechanical toys. GOTZ, G. June 9, 1949, No. 15361. [Class 132 (iii)] A mechanical toy comprises one or more vehicles 4 which roll-on an inclined track 3, and a clockwork driven endless chain hoist arrangement which lifts the vehicles one by one on a platform 5 to the starting position. A hook 13 on the platform becomes engaged on the chain when a vehicle moves on to the platform at the low position, and when the top of the hoist is reached the hook is disengaged by the stop plate 17 and the platform falls after the vehicle has rolled on to the start of the track. In dropping, the platform causes the spring motor to stop until a vehicle completes the run and initiates another sequence. Two vehicles are prevented from moving on to the platform at once by a locking device, Fig. 6 (not shown), consisting of a pivoted beam 24 and a swing plate 28.

Title: Improvements in or relating to apparatus for detecting flaws in protective coatings
Inventor: SAW PETER DOREE
IPC: G01N27/20
Filed: 1958-05-14
Abstract: 856,092. Transistor oscillator circuits. TYER & CO. Ltd. Dec. 16, 1958 [May 14, 1958], No. 15432/58. Class 40(6). [Also in Group XXXVI] Fig. 1 shows the circuit of an apparatus for testing flaws in insulation applied between the terminals OP and TE which is earthed, (see Group XXXVI). A low voltage D.C. supply is applied across terminals X, and is switched alternately across the primary windings of a step up transformer T by virtue of the push-pull oscillator comprising transistors TR1, TR2. The peak secondary voltage is rectified by valves V1, V2 connected in a voltage doubler circuit. Transistors TR4, TR5 are connected as a relaxation oscillator the oscillation frequency being determined by capacitor C6 and the constants of loud speaker LS. Normally the oscillator is rendered inoperative by the negative voltage applied to it from the junction of resistor R8, R7 and variable resistor RV2 which causes TR4 to saturate. The leakage current in an external leakage path between terminals OP, TE flows via the cathode of V2, R7, RV2 so that when a certain value of current flows, as predetermined by variable resistor RV2, transistor TR4 unblocks and the oscillator TR4, TR5 oscillates to produce a note, for example of 2000 cycles per second, in the loud speaker LS. Transistor TR3 acts as a clamp to prevent the base of TR4 moving too far positive the clamping level being determined by variable resistor RV1.

Title: Improvements in superheterodyne radio-receivers
IPC: H03G5/26
Filed: 1939-05-24
Abstract: 525,869. Superheterodyne circuits for wireless reception. PHILIPS LAMPS, Ltd. May 24, 1939, No. 15477. Convention date, May 27, 1938. [Class 40 (v)] Selectivity control, equivalent to a variation in coupling between the tuned circuits 2, 3 of an intermediate-frequency band-pass filter, is effected by connecting a circuit 7 tuned to the intermediate frequency in series with the capacity or inductance of the second circuit 3, the circuit 7 being also in the circuit of at least one of the control grids of the mixing tube 10, e.g. in the cathode lead as shown, and applying a varying potential over lead 27 to one of the control grids, e.g. the signal grid 14. The feed-back produced by circuit 7 may be positive or negative but is preferably positive and in this case the control voltage must become more negative with an increase in intensity of the desired signal or a decrease in intensity of an adjacent disturbing frequency. The impedance of circuit 7 may be low so that one side of the oscillator condenser 20 may be grounded without the cathode being at a high-frequency potential and any feed-back between the local oscillator and the signal grid 14 is prevented.

Title: Process and apparatus for the treatment of liquid manure
Inventor: EISELE FRANZ
IPC: C02F3/16
Filed: 1975-04-16
Abstract: To treat liquid manure for the purpose of eliminating odours, the liquid manure is enriched with oxygen by an aerator (1) in a storage container (e). This enriched liquid manure is conveyed by a pump (f) by way of a delivery line (g) into the stable into a flushing channel (a). The storage container (e) is thus located directly in the liquid-manure circuit generated by the pump (f). The accumulated animal excrements are also washed out in the flushing channel (a). At the end of the flushing channel (a), a retaining sluice (b) ensures that a sliding bed of liquid is maintained. The retained liquid at the same time picks up the substances which have occurred freshly there and which sink in it and prevent a further emission of odours into the stable. The stable air is thereby improved substantially. <IMAGE>

Title: Circuit arrangement for the counting stages of a ring counter
IPC: H03K23/00
Filed: 1962-04-27
Abstract: 993,368. Tunnel diode bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. April 27, 1962 [April 28, 1961], No. 16183/62. Heading H3T. [Also in Division G4] Each stage of a ring counter comprises a tunnel diode store 11, a delay circuit 12, and an AND gate 13, the pulses Z to be counted being applied to all the AND gates simultaneously. When the store 11 is set to 1 it produces an output pulse which combines at 13 with a count pulse to set the store 11<SP>1</SP> of the next stage and simultaneously return the store 11 to 0. The store 11 comprises a tunnel diode TD1, Fig. 2, which applies high or low voltage, to represent 1 or 0 respectively, to delay circuit R2, L1, R5. This is insufficient to move monostable TD2 from low voltage condition unless it is reinforced by a count pulse at Z when TD2 changes to high voltage condition to affect the next stage. Simultaneously TD2 restores TD1 to 0 condition and then restores itself. For higher frequencies resetting of TD1 is effected by the counting pulse through inductive coupling L2, L3, Fig. 4. Monostable tunnel diode TD3 is triggered to produce a - ve pulse at point b, so unblocking D2 so that TD1 restores quickly. In Fig. 5 the monostable TD3 is used without TD2. The coincidence of high potential at point a with negative at b, resulting from count pulse Z, triggers TD3 to restore TD1. Simultaneously a pulse passes through transformer L3, L4 to the next stage.
