Title: Mechanically propelled toy with automatic reversal in the opposite direction
IPC: A63H29/04
Filed: 1937-04-28
Abstract: 494,347. Travelling toys. MULLER, H. April 28, 1937, No. 12119. Convention date, Feb. 26. [Class 132 (iii)] A mechanically propelled toy has means operable by the impact of the toy when colliding with an obstacle to change the drive from one speed in one direction of travel to a different speed in the opposite direction of travel. The slide o, Fig. 1, on impact with an obstacle when reversing, is moved to release the cross-shaped lever p which rotates clockwise under the action of the spring u to move the guide disc w on the spur wheel m and change the drive from the backward slow running gearing b, c, f, m to the forward fast running gearing b, c, f, g, i, m, Fig. 3. Reversal from forward to backward running is effected by manually moving the slide o or by impact with an obstacle of a pushrod provided at the front end of the toy which may be a continuation of the slide o. In the latter case the springu exerts a damping effect. Several modifications of the construction shown in Figs. 1 and 3 are described. In the construction shown in Fig. 4 the running axle k to which is secured the spur wheel m is carried in a stirrup n, pivoted at y, connected at one end to the slide o and extended upwardly into a weighted lever z which moves to the left and effects movement of the spur wheel m on impact of slide o with an obstacle. Changeover of running to the opposite direction can be effected by manual operation of the slide o or lever z or by impact with an obstacle of an extension of the slide o at the front end of the toy.

Abstract: 1,108,149. Measuring rate of fluid flow electromagnetically. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 15, 1967 [March 22, 1966], No. 12168/67. Heading G1N. In an induction flow meter, particularly for use in the measurement of the flow rate of liquid sodium in a nuclear reactor, the coils 10, 11, Figs. 2, 3, producing a D. C. magnetic field are connected in series with the electrodes 12, 13 across which the induced voltage, indicative of flow rate is measured, so that they are supplied with current by the flow meter itself. The flow meter comprises an annular magnetic member 8, housed in an annular chamber 2, Fig. 1 (not shown), filled with an inert gas, which carries two pole pieces 9 round which the windings 10, 11 are wound. Electrodes 12, 13 are also supported from the pole pieces and are soldered to the inner wall of the chamber 2 by which they make electric contact with the liquid sodium. For starting purposes, the steel of at least the member 8 has a fairly high residual induction so that it retains sufficient flux at the end of one measurement to start the next. To prevent a back flow of sodium which might destroy the residual flux in the member 8, a non- return valve is provided in the pipeline 1.

Patent GB-400932-A (GB)
Title: Improvements relating to safe load indicators for cranes and the like
IPC: B66C23/90
Filed: 1932-04-30
Abstract: 400,932. Dynamometers. WYLIE, H. N., 5, Clement's Inn, Strand, London. April 30, 1932, No. 12483. [Class 106 (ii).] A safe-load indicator for cranes and the like comprises a device 9 adapted to indicate or signal under one or more definite forces imposed upon it by members 4, 6 which deflect the load rope or the jib-supporting rope, the indicator being pivoted on the crane mast or other fixed part. As shown in Fig. 1, the load rope 1 passes over sheaves 2, 8 mounted in frames 4, 6 ; the frame 4 is pivoted on the crane mast at 5, and the frame 6 is connected with the frame 4 by a pivot 7 and a strut 9 which forms the load-sensitive device. The strut 9 may be an indicator as described in Specification 400,428. Movement of the frames is limited by stops 11, 12 bearing on the mast, and the arrangement is such that the struts 9 yields and gives a signal with a constant load on the crane when the load rope is between the positions p, q, and with smaller loads as the load rope moves from q towards t. In modifications, not illustrated, the stop 12 is omitted or is brought into operation after a limited movement of the indicator about the pivot 5. As shown in Fig. 2, the strut 9 of Fig. 1 comprises two groups 13 of steel leaf springs clamped at their ends by a bar 10 in the frame 6 and a bar 14 in the spindle of the sheave 2. A distance bar 15 between the springs 13 is connected with a lever 21 and signal arm 22. The springs 13 are normally deflected by a stop 19 on the frame 6. Under a given compression stress, the springs yield until a collar 18 on the rod 15 comes against the stop 19, and a greater stress compresses a spring 16 against the collar 18 until the rod 15 comes against a stop 23, the arm 22 thus giving a warning and a danger signal in succession. In a modification, Fig. 3 (not shown), the device is applied to the jib-lifting rope, and the sheaves 2, 8 are replaced by a sector fixed in the frame 4 and by a link which is pivoted in the frame 6, is anchored to the crane mast, and forms the anchorage for the standing end of the jib-lifting rope. In modifications not illustrated, the frames 4, 6 may be pivoted together at 5 instead of at 7 ; the member 9 may be subjected to tension, bending or torsion ; the device may close electric circuits operating lights or bells or it may move a member into operative position so that a bell or sounding plate is operated when the rope 1 is paid in or out. For recording the amount of an overload, the stop 23, Fig. 2, may comprise a block of soft metal, such as aluminium, which will be marked by a hard point on the bar 15; or, as shown in Fig. 2A, the stop comprises a pin 30 pressed outwardly by a spring 29, and a record is left by a sleeve 32 which moves inwardly with the pin and remains in its inmost position upon a fixed sleeve 33 when the actuating force is withdrawn.

Title: Improvements in or relating to circuit-breakers
IPC: H01H1/22
Filed: 1969-03-10
Abstract: 1,262,963. Automatic circuit-breakers; partly electromagnetic switches. HUNDT & WEBER G.m.b.H. 10 March, 1969 [8 March, 1968], No. 12506/69. Heading H1N. A contact piece 6 of the stationary contact 5 of an automatic circuit-breaker is arranged on a plate 7 extending in the direction of current flow along the movable contact member 3 so that, upon short circuit, electrodynamic repulsion between the plate 7 and the movable contact member 3 separates the contacts against the biasing force of the main latching mechanism (not shown). An auxiliary latch lever 18 holds the contacts apart in the intermediate position shown, and is releasable electromagnetically or manually to allow closing or reclosing. A rectilinearly moving armature 22 of an electromagnet 21 engages the latch lever 18 to release this auxiliary latch. The main closing action of the breaker, from fully-open position to the intermediate position, is done manually, or by pneumatic, hydraulic or electrical devices, or by a small high speed motor, or the auxiliary latch may be rendered inoperative and the main mechanism used to actually close the contacts. Normal electromagnetic release fully opens the contacts. Plate 7 terminates in a cross-piece 8 from which extend parallel conductor bars 9 leading to a connector piece 10 connected to the terminal 11, and the plate 7 rests on a leaf spring 12 which effects damping by friction. Contact 3 is resiliently mounted on its arm 2 by a compression spring 14, and arm 2 extends through a slot 13 of a carrier to which contact 3 is connected, to allow vertical play for the contact 3. A damping device 15 controls vibration. Mica sheets 16 insulate plate 7 and conductor bars 9 and protect against creepage. An arc chamber (not shown) is provided to de-ionize the arc blown into the chamber by the contact arrangement. In a multi-pole breaker with a common operating mechanism, the auxiliary latch lever 18 is provided for the central movable contact member only. Lever 18 is replaceable by two levers on either side of arm 2 operated by a single electromagnet 21. Lever 18 engages a transverse bar 26 on arm 2, and this bar may connect together all three arms 2.

[Also in Division B5] An insole member 1, Fig. 1, moulded from a thermo-plastic resin (see Division B5), e.g. cellulose acetate, has a reinforcement member 8 of open framework construction embedded in its waist portion 4. Member 8, formed by bending a single strip of spring steel, comprises upper and lower leaf portions separated by a corrugated portion and is flexible about a transverse axis until the insole material hardens. The surface of the reinforcement component may be phosphate-coated, shot-blasted or perforated to improve adhesion between the resin and the metal and may be coated with adhesive before moulding. An insole blank B, Fig. 7, containing member 8, is first formed by injection moulding. The blank B is then warmed until mouldable and conformed to the shape of a last with which the insole is to be used. A toe portion, e.g. of leather, is stuck on to a chamfered end portion 6 of the insole. An insole blank for very high-heeled shoes may be formed in a suitably shaped mould to reduce the degree of moulding required on the last. Fig. 3 (not shown) illustrates a modified reinforcing member. Other insole materials are high-impact polystyrene, P.V.C., polythene and nylon.
