Title: Safety pins
IPC: A44B9/18
Filed: 1920-09-30
Abstract: 171,573. Petersen, N. L. Sept. 30, 1920. Safety-pins.-Safety-pins are made from two separate pieces of wire having their ends held in cases of pressed metal by depressions therein, without the use of rivets. The catch for the point of the pin consists of a case that may be slidable on the frame. In the form shown in Fig. 1, the pin a is clamped in the case c by depressions e. A circular depression f forms a pivot, round which is coiled the end of the frame member b, to the other end of which is clamped the sheath d with slots g for the point of the pair. The movement of the pin is restricted so that it must be slightly bowed to enter the slot. In a modification, the sheath d is arranged to slide on the frame b, its movement being limited by depressions, so that the pin cannot become disengaged till the sheath has been slid outwards. In the pin shown in Fig. 3, the two bars of the frame are formed of a. single bent wire b, to which the case c and sheath d are clamped by depressions h. The rear end of the pin a is formed into an eyelet a', through which passes the inturned end of the wire b. Fig. 4 shows a similar form, in which the pin is split at its rear end, the parts being bent at right-angles and engaging between the sides of the case c, being retained by depressions i. The sheath d slides on the frame, and is normally held in the closed position by catches c<2> engaging in perforations on the sheath.

Title: Improvements in or relating to magnetic storage devices
IPC: H03K17/82
Filed: 1954-09-28
Abstract: 789,668. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 28, 1954 [Oct. 1, 1953], No. 27958/54. Class 38 (2). [Also in Group XXXIX] For non-destructive reading a sensing winding 13 is linked with only a part of the magnetic storage core. In Fig. 2 the winding 13 is passed through two holes 14 in the core. A pulse in the winding 13 produces an auxiliary flux which disturbs the main flux and produces a voltage pulse in the output winding 12. The sign of the output pulse is independent of the sign of the sensing pulse but depends upon the direction of the main flux in the core. The sensing winding may be fed with alternating current the state of the core being indicated by the phase of the output. If the alternating current is of sawtooth waveform a substantial voltage is produced in only one direction which is dependent upon the direction of the main flux in the core. If the holes are arranged so that winding 13 is not linked with the main flux in the core, pulses in the input winding 11 will not affect the sensing winding 13. In a modification, Fig. 3, the sensing winding 23 is linked with part of the core between a hole 24 and the outer periphery of the core. Specification 749,796, [Group XXXIX], is referred to.

Filed: 1972-06-15
Abstract: 1350852 Vehicle control system GENERAL SIGNAL CORP 15 June 1972 [30 June 1971] 28004/72 Heading B7H [Also in Division G3] In control apparatus for controlling vehicles moving on a path divided into zones, e.g. for controlling air cushion vehicles propelled by a linear induction motor on a guide track divided into blocks, the end of the blocks overlap and speed information is transmitted to the vehicles when in the overlap sections. The block sections A-C are provided at their ends with check-in and check-out receivers 10, 12, respectively, which co-operate with check-in, check-out transmitters 4, 6 mounted on the vehicle V. When, e.g. the check-in receiver 10 of block B is activated by transmitter 4 of a vehicle entering the block, a loop 8 which extends over the overlap between blocks A & B is energized with a speed control signal for the vehicle, determined in accordance with the traffic in advance, until the check-out transmitter 6 on the vehicle activates check-out receiver 12 of block A. The blocks of the guideway are provided with inert coded markers, alternately code I or II, which generate signals on the vehicle from which its speed is determined. On entering a block, a signal is received from loop 8 whereby the vehicle speed determining apparatus is adjusted to the correct code. On the vehicle the speed control signal indicative of required speed limit is applied from receiver 22 to governor 32 and speed regulator 34 which also receive actual speed signals from speed sensor 24. The governor acts to hold off emergency braking so long as the actual speed does not exceed the required speed limit and the speed regulator controls the propulsion system 40 and service brake 35 in accordance with the actual and required speeds. An accelerometer 50 and jerk control 44 are provided for smooth regulation of the propulsion system, the accelerometer also being connected to the emergency brake control to delay emergency braking if the vehicle is decelerating at a proper rate after a speed limit change. A profile generator 33 is also connected to the speed regulator whereby, e.g. on being triggered by a wayside marker 64 in approach to a station a stopping speed profile is provided to the regulator to control the vehicle to a halt.

Title: Improvements in means for controlling the speed and power factor of alternating current slip ring induction motors
IPC: H02K17/36
Filed: 1926-11-10
Abstract: 281,076. Houghton, T. E., and United Alkali Co., Ltd. Nov. 10, 1926. Alternating-current induction machines.- The invention relates to a system for controlling the speed and power factor of a slip-ring induction motor in which the secondary of the motor C is connected to a source of continuous current Q through a regulator set comprising a synchronous machine F directly coupled to a continuous current machine G. According to the invention, the alternating current member of the synchronous motor is connected to the induction ' motor through the switch E after the induction motor has been started and the starting resistances D cut out, and then the starting resistances are re-inserted until finally, the sliprings care closed only by the rotor of the synchronous machine. This operation may start the regulator set if the field switch L of the synchronous machine is closed, but in any case, starting may be effected from the continuous current side by closing the field and armature switches M, N of the machine G and cutting out the armature resistance O. Power is supplied to or taken from the continuous-current source according to whether the induction motor runs below or above synchronous speed and this is determined by the position of the change-over switch M in the field circuit of the machine G. Speed regulation of the induction motor is effected by adjusting the resistance K in the field circuit of the continuous current machine, and power factor regulation by adjusting the resistance H in the field circuit of the synchronous machine. The auxiliary continuous-current supply may be obtained from the alternating- current system A through a rotary converter or motor generator. Overspeed devices may be provided to trip the circuit breakers in the event of an undue rise of speed of the regulator set.
