IPC: G07F15/12
Filed: 1928-05-24
Abstract: 317,886. Hamlett, H. W. May 24, 1928. Telegraph and telephone apparatus; coin action, weight.-In coin actuated mechanism as described in Specification 217,639 for closing for a predetermined time one of the circuits of a wireless receiving apparatus, the. switch operating member 18, Figs. 1 and 2, is bifurcated, one of the arms 20 controlling the high tension, while the other arm 22 control the low tension circuit. The member 18 is pivoted to a bell-crank lever 14 provided with a spring 15 engaging a counterweighted coin lever 6 which, when a coin is inserted, allows the spring contacts 21, 23 of the switch to press back the member 18. The movement of the bell-crank lever 14 causes a wiper 17 to flick a balance wheel 12 and start a clock-work 1, on an arbor 5 of which the lever 6 is loosely mounted. A pawl 10 on the lever engages a ratchet wheel 11 on the.arbor 5 so that the lever descends slowly, under the weight of the coin, as the ratchet wheel is rotated by the clockwork. When the coin falls off the lever after a predetermined time, the lever returns and engages the spring 15 to rock the bell-crank lever thereby 'stopping the clockwork and opening the switch contacts.

Abstract: 1,088,817. Unattended collection of fares. GENERAL ELECTRIC CO. April 6, 1966 [May 6, 1965], No. 15321/66. Heading G4T. In a system for the unattended collection of fares in a transport system, upon entering the system a traveller is issued with a ticket bearing a coded representation of the point of entry at an entrance turnstile, and upon desiring to leave the system the traveller first has to present his ticket to a validating device which computes and indicates the fare due and which, when the fare due has been paid-either in cash or by a credit card scheme-imprints a validating mark upon the ticket and returns it to the traveller, and secondly the traveller has to present the validated ticket to an exit turnstile which checks the validating mark, retains the ticket and allows the traveller to exit. Validating devices can either be located adjacent exit turnstiles and be pre-set for exiting at the particular exit where they are located, or they can be dispersed over the transport system so that whenever a traveller has some free time, e.g. when waiting for a vehicle, he can validate his ticket; in this case means, e.g. press-buttons, are provided on the validator so that the traveller can indicate his intended point of exit.

Title: Improvements in or relating to screw and half-nut mechanisms particularly for machine tools
Inventor: BROWN GRAHAM MAURICE
IPC: B23Q11/12
Filed: 1960-05-03
Abstract: 949,676. Screw and nut gearing. GEORGE RICHARDS & CO. Ltd. May 2, 1961 [May 3, 1960], No. 15620/60. Heading F2Q. In a mechanism, particularly for automatically controlled machine tools, wherein a long half-nut secured, for example, to the machine bed is engaged by a rotatable screw 3 mounted, for example, in the machine carriage, gas or liquid lubricant is supplied under pressure to a plurality of outlets 11 in opposite side faces of the screw thread, the gas or liquid pressure being high enough to prevent metal-to-metal contact, thus reducing static friction and preventing backlash. The gas or liquid lubricant also provides viscous damping. As shown, the screw 3 has a passage 10 supplying oil to a central gallery 9 from which it passes through individual passages (only one shown) and restrictors 14 to individual arcuate grooves 11 in the thread faces. Oil drain passages 2 are provided in the nut. Since the screw is engaged by the nut over only half of its circumference most of the oil emerges ineffectively through the uncovered grooves 11. The different pressure exerted by the oil on the two faces of the screw thread are determined by the clear' ance and the axial load. In a modification the oil is replaced by gas, e.g. air, emerging through restricting orifices in the screw thread, the restrictors 14 and arcuate grooves 11 being omitted.

Title: Motor control system
IPC: H02P5/68
Filed: 1928-05-30
Abstract: 320,032. Latour, M. May 30, 1928. Exciting.-A motor control system, particularly for traction motors, comprises a main driving motor 1, a separately driven exciter 9 supplying the field winding 2, and an auxiliary series motor 6 coupled to the main motor and connected across it in series with the field winding 8 of the exciter, means such as a resistance 12 having a positive or a negative temperature coefficient being connected across the exciter field winding for varying the excitation of the main motor. The system is particularly applicable to regenerative braking. The exciter 9 is driven at constant speed by a shunt motor 10 which may have a separate low-voltage commutator to supply the field winding 11 if the voltage of the line 3 is too high, and when operating regeneratively, the motor 1 will generate at all speeds an E.M.F. proportional to the line voltage. The resistance 12 may have a positive temperature coefficient so as to cause a more than proportional increase in the excitation of the main machine upon a fall of speed. When the system is used for speed control in normal operation a variable resistance 13 may be connected across the exciter field winding. The field winding of the main motor may be connected in series with the armature, and the exciter may be provided with additional shunt or series windings connected to its own armature or to the armature of the main motor. An auxiliary motor such as 6 having two independent commutators and exciting windings may be provided for each pair of main motors, and any change such as from parallel to series connection of the main motors must be accompanied by a similar change in the connection of the auxiliary motor. The changes of connection or variation of resistance in the motor circuits may be effected automatically by a centrifugal governor on the shaft 5, but for low speeds, manual operation is preferable.

Abstract: 1285228 Automatic speed control SCHLOEMANN A G 6 April 1970 [18 April 1969] 16189/70 Heading G3R A system for coiling wire or other elongated material on to a reel rotated by a motor includes a cam, driven by the reel, which sets a potentiometer to provide a desired speed reference signal. An actual speed signal is derived from the reel drive, and the speed of the reel is controlled in accordance with the difference between the two signals. In the system shown, a motor 1 drives a pump 4a feeding an hydraulic motor 4b, the output shaft 8a of which drives a worm gear 8 which rotates a reel or drum 9 on to which material from an extrusion press is being coiled. The shaft 8a also drives a tacho-alternator 10 to provide an actual speed signal on line 21, and, through a stepless gear 12, a cam disc 13. A member 14 is biased against the edge of the disc 13 and adjusts the setting of a potentiometer 15 as the cam rotates. The resultant voltage on line 22 forms a reference with which the actual speed signal is compared in a regulator 18, the output from which controls an hydraulic device 19 to adjust the pump 4a. The profile of the cam disc 13 is symmetric about a diameter, one half controlling the speed of drum 9 during a lay in which the coiled material spirals inwardly, and the other half controlling the speed when the material spirals outwardly. The supply to the potentiometer 15 is derived from a potential U 1  representing the speed of the extrusion press. A transformer 26 expresses the deformation ratio of the material before and after extru - sion.
