Title: Improvements in rotating toys with varying speed and orbit
IPC: A63H27/04
Filed: 1963-04-30
Abstract: 958,016. Captive flying machines. REMPEL MANUFACTURING Inc. April 30, 1963 [May 15, 1962], No. 16988/63. Heading A6S. A rotatable toy comprises a partially balanced flying object on one end of an arm 9 pivoted on a central support 6, the rotational drive of which is automatically interrupted and restored. Drive is effected through ratchet teeth 13 by a battery-operated motor 3 in the base 1 when a circuit through a battery 5 is completed by the mutual attraction of a magnet 11 on the base of an airplane 10 and a magnet 21 on a switch 23, thus causing the airplane to rise, and then immediately to break the circuit again. Four switches 23 in parallel are arranged around the base 1. In a second embodiment the flying object comprises a capsule 42, again partially balanced by an adjustable weight 12, which orbits around a globe 25. Intermittently, magnetic attraction between the switch members 34, 36 restores the circuit of the motor. A centrifugally operated switch in the capsule 42 switches on lights within the capsule as it accelerates.

Title: Lathe copying apparatus
IPC: B23Q35/18
Filed: 1962-05-03
Abstract: 947,678. Copying lathes. SZERSZAMGEPFEJLESZTO INTEZET. May 3, 1962 [May 12, 1961], No. 17047/62. Heading B3T. Copying apparatus for a lathe comprises a tool slide 8 movable by hydraulic means whereby fluid admitted to spaces 11a, 11b on each side of a piston, causes backward and forward movement respectively of the slide. The slide houses a copying bar 6 which controls the fluid flow from a pump SZ to the spaces 11a, 11b. When the apparatus is idle a spring 1 cooperates, via a solenoid EE, with an arm 2 causing the bar 6 to move against spring 7 and be locked in this position. The withdrawal of the slide is thus effected by the fluid pressure in the space 11b while fluid in space 11a may exhaust to a sump. To initiate the operation cycle, solenoid EE is energized, acts against spring 1 which releases arm 2 allowing movement of the bar 6 permitting fluid to move the slide forward to a position determined by an arm 3 in co-operation with a stop 4 on a stop holder 5. This promotes a condition of equilibrium between the fluid pressures in spaces 11a, 11b which maintains the slide in position determined by the stop 4 corresponding to a given work diameter. A template 10 determines the longitudinal stop positions by means of a follower carried on an arm 9, such that when said stop is reached a contact UM on arm 9 closes breaking the circuit permitting the return of the slide to its starting position. As the slide returns a ratchet-wheel 14 is rotated by a pawl 12 said rotation being transmitted to a toothed wheel 19 on the same shaft as the ratchet-wheel 14. This transmits movement to a rack 20 which moves against a spring 21 to move the stop holder 5 through one division. The slide moves longitudinally by a fast traverse to stop U1, the traverse then being disengaged and the advance of the tool to the work effected and the turning of a new diameter begins. The copying operation thus being carried out throughout the whole length of the workpiece in accordance with the shape of the template 10. A cycle controlling adjusting disc 26 is threaded coupled to rack 20, the setting of said disc enabling the number of machining cycles to be set in advance. A micrometer adjustment on sleeve 28 effects the movement of the copying bar 6 which changes the machining depth of the cutting tool.

Abstract: 1,104,141. Logarithmic amplifiers. SMITHS INDUSTRIES Ltd. 23 April, 1965 [24 April 1964], No. 17217/64. Heading G4G. [Also in Divisions G1 and H3] In the measurement of the expended life of a gas turbine engine in an aircraft (see Division G1), it is found that the rate R at which the units of permissible engine life are used up depends on an approximately logarithmic way on the temperature T of the jet pipe above a temperature TA, Figure (not shown); below this temperature the rate R A  is constant. The difference in temperature T-T A  between the jet pipe and the temperature T A , measured by a thermocouple (1), Fig. 1 (not shown), connected across the output of a variable bridge (2), is fed to an amplifier circuit (3),Fig. 4, having a non-linear degenerative feed back where it is converted into a corresponding rate signal R-R A . The circuit (3) comprises a preamplifier stage 40 and main amplifier state 41 with feedback provided by series-connected resistors 42, 43 shunted by a series-connected chain of Zener diodes 44, 45, 46, 47 which modify the degree of feedback to the pre-amplifier 40 in accordance with the output current at the stage 41, so that the overall gain of the circuit (3) increases with the law of the curve relating T to R, Fig. 1 (not shown). In a modification in which the life of an engine is determined both by the temperature and the engine speed, the characteristion of the non- linear network is varied in accordance with the speed.

Filed: 1951-07-24
Abstract: 708,128. Public address systems. STANDARD TELEPHONES & CABLES, Ltd. July 24, 1951, No. 17509/51. Class 40 (4) The normal programme on a sound distribution system may be faded out and an employee called by a coded signal automatically at the operation of the appropriate key. Gramophone or radio programmes are normally supplied over contacts d1, d2, an amplifier and a selector to certain loudspeakers. An operator calls an employee by depressing the appropriate selection key KA-KZ and then the start key, the latter energizing a motor to rotate cams 1 and 2 and a potentiometer fader, which fades out the normal programme in a half revolution. At this point, contacts 1c2 open to stop the motor and contacts 2c1 close to energize relay L, which locks up, energizes slow-operating self-interrupting relay M, energizes the relay T, S. or R corresponding to the key KA-KZ depressed, and energizes relay D which cuts off the normal programme at d1, d2 and switches in at d3 certain extra loudspeakers which are used for calling employees but not for the normal programme. The selected relay T, S or R together with M control the stepping magnet TS, SS or RS. Circuit is made in Morse code sequence over the wiper TS1-8, SS1-8 or RS1-8 according to the key KA-KZ operated to relay N, which connects and disconnects an oscillator to the amplifier and loudspeakers to call the required employee, bridging wipers being used to ensure continuous tone in the production of a dash. A second employee can be called by releasing the first key KA-KZ and operating another key. To resume the normal programme the stop key is thrown to re-energize the motor, L releasing when the working switch TS, SS or RS reaches  home position to energize P. Modifications. The contacts of keys KA-KZ can be arranged in known manner, Fig. 3 (not shown), to allow only one key to be operative at a time. The start key can be replaced by extra contacts on keys KA-KZ, Fig. 4 (not shown). Automatic return of the normal programme can be made under the control of a thermal switch, Fig. 5 (not shown). The coded signals can be made by castellated cams instead of the switches RS-TS. The interrupt- . ing programme can be faded in and out, Fig. 6 (not shown).
