Title: Mechanical toy
IPC: A63H18/02
Filed: 1931-07-02
Abstract: 372,148. Toys. ARNOLD, C., 47, Deutschherrnstrasse, Nuremberg, Germany. July 2, 1931, No. 19123. [Class 132 (iii).] A toy clockwork vehicle 6 is propelled round a circular track 5 by releasing a spring-pushed member 10 which passes through a slot 4 in the track and strikes the end of the vehicle, the vehicle continuing to run under the drive of its own clockwork. As the driving spring runs down, it forces out a member 16 which drops into the slot 4, and the vehicle is thereby braked. A pivoted catch 14 serves to release the spring-urged member 10. Sparks may be produced by a pivoted cerium stone holder on the vehicle running along an emery band 17 fixed on the track 5.

Title: Improvements in timing devices
IPC: G04C13/00
Filed: 1959-06-05
Abstract: 882,301. Electric clocks. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 5, 1959 [June 5, 1958], No. 19247/59. Class 139. [Also in Group XIX] In an electric clock a synchronous motor drives the lowest order register through a pawl and ratchet mechanism and each further register is driven by pawl and ratchet transfer mechanism. Each register comprises an indicator drum and a wiper arm which is rotated in step-by-step manner over a printed circuit contact bank and is periodically connected to a read-out apparatus. The synchronous motor 14, Fig. 1, drives a cam 72 having three cam surfaces 74, 75, 76. The cam surface 74 co-operates with a cam follower lever 78, Fig. 3, connected to a pawl 58 which actuates a ratchet connected to the drum 36 of the minutes register 20a, Fig. 1. The transfer mechanism between the minutes register and the tens of minutes register 20b comprises a cam 46, a cam follower lever and an associated pawl and ratchet mechanism. A similar transfer mechanism is located between the tens of minutes register 20b and the hours register 20c. Each register includes a threearmed wiper 32, Fig. 1, which moves over a contact bank printed on a board 22, and a disc 40, Fig. 3, having peripheral slots in any of which a peg 44 may be located. The cam surface 75 co-operates with a lever 94 fixed to a shaft 92 which carries three sensing arms 90 each of which co-operates with a slotted disc 40 and each of which carries a switch actuator 88. The arrangement is such that the cam 75 allows the lever 94 to swing clockwise once every minute provided such movement is not blocked by a peg 44 in the path of one of the arms 90. The instant or instants at which clockwise movement of the lever 94 is allowed is therefore predetermined by the location of the pegs 44. During this movement of the arm 94 the switch actuators 88 close their switches 85, 87 Fig. 3, so that each wiper is connected to a read-out device. The cam follower 78 is locked during a read-out operation by a latch arm 100 controlled by the armature 108 of a delay magnet 118 so that the registering drums 36 are not actuated during a read-out operation. The latch arm may be connected to the armature of the delay magnet. The cam surface 76 subsequently releases the latch arm 100 from the follower lever 78. The drums 36 may be stepped-on for setting purposes by manual operation of levers connected to the pawls.

Title: Improvements in or relating to electric wave analysers
IPC: G01R23/00
Filed: 1946-06-28
Abstract: 630,858. Harmonic analysis ; distortion measurement. STANDARD TELEPHONES & CABLES, Ltd., TACOBSEN, B. B., and PAINE, J. June 28, 1946, No. 19411. [Class 37] Fig. 1 shows a block schematic of an electric waveform or harmonic analyzer applicable to testing the linearity of thermionic amplifiers such as are used in a telephone transmission system. The test amplifier is connected to the analyzer in a self-oscillatory loop circuit (a) comprising a coarsely variable attenuator 1, an impedance network masking the variable input impedance of a band-pass filter 1 which feeds a phase reversing switch X, a finelyvariable attenuator 2 embodying a level stabilizing network containing a metal filament lamp, and a variable attenuator 3. The attenuators adjust the level of loop gain and regeneration. Point P in the output of attenuator 1 is connected to fundamental measuring circuit (b) including fixed attenuator 4 through switch S1 to either the matching dummy load RT1, or to the db. calibrated voltmeter VM and load RL indicating the power level at P, which is adjustable by the attenuators controlling the loop feed-back, the phase angle of which may be reversed by switch X so that oscillations are set up within the pass range of the band-pass filter 1. A distortion component measuring circuit (c) is connected at P and comprises a narrow band-pass filter 2 which accepts the desired harmonic of the fundamental oscillation frequency of the loop circuit and is tunable over a small range, a switch S2 selecting a high or low level output, a calibrated variable gain negative feed-back amplifier, and a selector switch S3 whereby the amplifier output may be alternatively connected to the voltmeter VM or to the matching dummy load RL. Similar distortion measuring circuits such as (d) tuned to other harmonics of the fundamental may be connected to point P. The power level at P may be set up to any required figure within the output capacity of the amplifier under test and measured by the voltmeter through circuit (b), the loss in which is known. Since the gain of the measuring circuit C is also known, the level of the second or other selected harmonic is calculable relative to the power level at P. Fig. 2 (not shown), gives the detailed circuit of a harmonic analyzer of the kind described, which measures the second harmonic of a fundamental frequency of 60 kc/s. The device may embody an oscillator for calibrating the distortion measuring circuits.

Abstract: 1,120,528. Testing for leakage. DAVID BROWN TRACTORS Ltd. April 28, 1967, No. 19756/ 67. Heading G1S. A hydraulic leakage testing device comprises a piston 27 slidable in a cylinder 25, an actuating member in the form of a ram 21 coacting with said piston, a first port 32 in the cylinder on the high-pressure side of the piston crown 56 connectible to a hydraulic assembly to be tested, a second port 33 in the cylinder on the low-pressure side of the piston crown and means 35 connected to the second port to indicate the amount of displacement of the piston in the cylinder. Fluid is directed into the hydraulic assembly under test and into the cylinder 25 through port 32 until the piston is in the position shown. The reading in indicator 35 is noted and the reading in a second indicator 45 is zeroed. Pressure is then applied to the cylinder 20 which exerts a thrust on the piston via the ram 21 to create a high-pressure in the assembly under test. Any leakage within the assembly results in displacement of the piston within the cylinder facing liquid through port 33 into tube indicator 35. The piston is then forced back by applying pressure fluid in the other direction and a reading taken from the indicator 45. The difference in these two readings gives a measure of the rate of leakage.
