Title: Gun Toy having Sound Producing Means
IPC: A63H5/04
Filed: 1966-12-28
Abstract: 1,178,710. Toy gun. MATTEL Inc. 28 Dec., 1966 [28 Dec., 1965], No. 57993/66. Heading A6S. [Also in Division G5]. In a toy gun, disc record means are incorporated which play back a gunshot sound and subsequently the sound of a ricocheting bullet when the trigger is pulled. The gun is a rifle with the sound reproducing means in its butt. Forward movement of a cocking lever 174 rotates a gear 170 which drives a rack gear 156 via a pinion 158. This movement moves a rack 110 in the direction of arrow 180, compressing spring 148, until a gear 188 on the trigger mechanism 36 can be urged by one arm of spring 216 into contact with the end 230 of the rack. When the cocking lever is returned to its initial position a flat 236 on the rack gear is parallel to the rack and allows movement of the rack to the left without engagement of the cocking mechanism. A hub at the rear of gear 170 includes a first recess which is engaged by a detent on spring 216 to hold the cocking lever in its initial position and a second recess which co-operates with a projection of the trigger to prevent the trigger being pulled except when the cocking lever is in its initial position. During the final part of the movement of the rack to the right pick up arm 78 is lifted by a sloping lobe member 182 on the rack and moved to a position in which pick up needle 88 is over the outer track of record 40. The turntable record 40 is weighted by a metal ring 308 and is driven via a spring clutch 54, turntable gear 52 and gears 146, 130 from the rack 110. The speed of rotation of the record turntable is controlled by governor means including a pair of weighted brakes which are mounted on the periphery of the turntable and move outwardly against the action of springs, when the speed is excessive, into braking contact with a circular surface 265a. On pulling the trigger the rack moves to the left under the action of spring 148, the turntable is driven and the pick up arm moves out of contact with the lobe member 182 and its pick up needle enters the outer groove in the record. The pick up vibrations are passed via a piston which is spring urged into contact with the pick up arm to the cone speaker 90. At the end of the rack movement the pick up arm is lifted from the record by a second sloping lobe member 270 on the rack.

Title: A Frequency Meter
IPC: G01R23/10
Filed: 1966-04-22
Abstract: 1,150,664. Frequency discriminators. COMMISSARIAT A L'ENERGIE ATOMIQUE. 22 April, 1966 [22 April, 1965], No. 58438/68. Divided out of 1,150,663. Heading H3A. In a frequency meter, the A.C. signal whose frequency is to be determined is converted into a signal consisting of unidirectional pulses of the same frequency which are supplied to one input of a trigger circuit whose output is supplied with current from the time of arrival of one of the unidirectional pulses and until it receives a control pulse, derived from the output of a frequency divider, on a second input. The frequency divider is supplied with pulses of a higher predetermined frequency via a switch so connected to the output of the trigger circuit that it is held in its conductive state while the above output is supplied with current. The output of the divider is also supplied to an integrating current to provide an indication of the frequency of the original signal. A signal c, e.g. from a n.m.r. magnetometer as described and claimed in Specification 1,150,663, whose frequency is to be determined, is shaped by trigger circuit 23. The resulting rectangular pulses are then rectified and differentiated in circuit 24 to provide unidirectional pulses e which are fed to the trigger circuit 38 to open a gate 31 and allow reference pulses from a thermostated quartz clock 29 to pass through a differentiating circuit 50-52 to a frequency divider 34. The output m of frequency 204À8 kH2 from the clock is squared by Schmitt trigger circuit 30 and differentiated by a circuit 48-49. Once gate 31 has been opened, the divider 34 counts 1024 pulses before a signal is transmitted through differentiating circuit 53- 54 to an input 40 of the trigger circuit 38, which stops current flowing through the output 41 to block gate 31. Gate 31 is next opened by the arrival of the following pulse e at input 39. The output pulses from the frequency divider, corresponding to 1024 pulses K, are integrated by a circuit 42, 43 to give a direct voltage V 1 , proportional to the frequency to be measured. To reduce noise and thereby increase sensitivity, the measurement of the frequency is obtained from the difference between two voltages V 1 , V 2 , the latter being obtained by integration of the signal at output 37 of the divider 34. This difference voltage is supplied to a recorder (not shown), after filtering of the desired band, through an amplifier (not shown).

Title: A binary coded magnetic information store
IPC: G11C19/10
Filed: 1969-12-24
Abstract: 1,271,540. Magnetic storage arrangements. COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE. 24 Dec., 1969 [30 Dec., 1968], No. 62831/69. Heading H3B. A magnetic storage element comprises a helical path 10, Fig. 4, of thin film material whose easy axis of magnetization K lies in the film normal to the longitudinal axis of the helix. Bits are stored in the path as areas of reversed magnetization, and are written in by pulsing a conductor 18. The bits are propagated from a continuous ring 16 of film adjacent conductor 18 by a rotating magnetic field H, and may be read out by detecting pulses induced in a conductor 19 adjacent a second ring of film 17. The bits may be held stationary by passing an alternating current through a conductor adjacent the helix, this conductor either lying as shown at 20 or passing axially through the carrier body 13 around which the helix is wound. A D.C. bias may also be applied on these conductors. Two helices of opposite thread may be joined in parallel by anisotropic magnetic bridges which couple their end rings together, Fig. 6 (not shown), so that stored bits circulate continuously in the pair. Alternatively the helices may be wound on a common carrier body, Fig. 7 (not shown). Several elements may be arranged to form a store, Figs. 10, 11 (not shown), in which selection is achieved by inhibiting propagation in all but the desired element. Information may be rewritten after reading in the Fig. 10 embodiment. The element shown in Fig. 12 has additional conductors 41-44. Pulses may be applied to these conductors to convert an adjacent "1" into a "0". Conductors 41, 42 control writing, and conduc- 43, 44 control read out. Fig. 13 shows an arrangement of such conductors to form a store in which 4n elements are connected to form four Groups I-IV. Each input conductor 18 (or a) is coupled to one element in each group, while each control conductor 41-44 (or b-e) is coupled to all the elements in two groups. Each control conductor is also connected to one terminal of a bi-stable circuit B-E, and those circuits may be activated in such a way that only one of the groups at a time has both its writing control conductors in a state to allow a "1" to propagate. For example, if B gives an output at the terminal marked +, then group I is selected by an output from C + while group II would be selected by C-. Reading is similarly controlled, and simultaneous writing and reading may be achieved. In all the above elements, the alternating current may be used to erase stored bits by raising its amplitude.

Title: Gas-liquid centrifugal separator
IPC: B01D19/00
Filed: 1979-08-03
Abstract: A rotary gas/liquid separator includes a housing (10) enclosing a free running rotor (12) having an inverted conical inside surface (18), and turbine blades (36) adjacent an upper end of the surface (18). A gas/liquid inlet mixture is forced through stator vanes (92) which direct the mixture tangentially into the turbine blades for rotating the rotor. Centrifugal force exerted on the mixture by the rotating turbine blades separates the liquid from the gas. The separated liquid flows downwardly in a thin film along the inside surface (18) of the rotor and drips from a free lip (20) at the bottom of the rotor for collection. Fan blades (42) on the rotor discharge separated gas from a first chamber (134) below the rotor to a second chamber (136) above the rotor. A substantial pressure drop and corresponding adiabatic cooling of the gas result from passage of the gas through the turbine blades, and the fan blades increase the pressure and temperature of the gas in the second chamber relative to gas pressure and temperature in the first chamber. <IMAGE>
