Title: Control and connection system for multiplying devices, more particularly for automatic dispensers
IPC: G06F7/62
Filed: 1962-02-13
Abstract: 940,102. Counters. S. A. POUR TOUS APPAREILLAGES MECANIQUES, and SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES SUD-AVIATION. Feb. 13, 1962 [Feb. 22, 1961], No. 5532/62. Heading G4D. In apparatus in which two counters operate at related speeds, such as a fuel disperser or cableresistance calculator, a check is made on the relationship of the counters when a predetermined quantity has been entered into one of the counters. As applied to a petrol pump the cost per unit volume is set up on an external indicator by movement of a selector switch 29. Impulses I y , I p  representative of volume and price are supplied from generators at frequencies related by the price per unit volume. These impulses operate counters of known type to display the amount of petrol dispersed and the total cost. If the relationship is correct coincidence gate 30 operates. If however the relationship is not in agreement with the price displayed an alarm 50 is operated. A delay circuit R may be incorporated to allow a slight tolerance. A plurality of selector switches 29 may be used to give a multi-denominational price (Fig. 2, not shown).

Filed: 1943-04-14
Abstract: 564,916. Tempering glass. BELITSKY, J. April 14, 1943, No. 6009. [Class 56] Adiabatically expanded gas is used for the toughening of sheets of glass 31 which are suspended between jets in pipes 34 extending between upper and lower headers 33 supplied by inverted U- shaped pipes 32 from a header 35 to which the expanded air is supplied. The headers and jets are reciprocated vertically by an electric motor 38 driven by a generator 16 which is operated by a compressed air engine 15, the exhaust of which is connected to the storage cylinder 19 for the adiabatically expanded air. During reciprocation of the headers, valve operating levers 55 projecting from the valves supplying the jets engage in vertical slots in stationary plates 51 to vary the pressure and amount of the jets, whereby intermittent blasts may be produced. Jets of compressed air expanding normally may be used for the remainder of the cooling after the initial toughening by the adiabatically expanded air, supply of this air being from a separate storage cylinder 20.

Title: Method of and devices for producing and maintaining pendular motion by means of alternating currents or voltages
IPC: G04C3/033
Filed: 1952-03-12
Abstract: 707,701. Clocks, moving signs. CONSERVATOIRE NATIONAL DES ARTS ET METIERS, and LEFRAND, E. March 12, 1952 [March 22, 1951], No. 6440/52: Classes 31(1) and 139 [Also in Group XXXV] A conducting object is caused to move in a regular or irregular, circular or elliptical, pendular path for chronometric or display purposes by means of a ring of split-phase energized electrostatic or electromagnetic poles. In its simplest form, Fig. 1, a metal ball 13 is suspended over a ring of electromagnetic poles 25 fed with split-phase A.C. The ball executes its motion at its natural frequency and is propelled by induction motor effect by the rotating field produced by the poles. Starting may be achieved by means of an initial movement, by producing asymmetry in the pole-strengths, by putting a magnetic member on the mass 13, or by maintaining the pendulum at a radius by means of a rotary arm as shown in Fig. 4. In this form the electromagnets are radially arranged and the metal mass 43 has limited radial movement in a slot 64 in the freely rotatable spacing arm 62. The mass 43 is supported by a rod 44 and link 47 to drive a clock mechanism 68. In a modification (not shown), the electromagnets 53 are replaced by a three-phase induction motor stator having a fixed squirrel cage whose bars emerge beyond the stator core, the induced current in this cage producing the rotating field. Alternatively a commutated D.C. winding may be used to produce the rotating field. In a further form, Fig. 7, a suspended mass 93 is fitted with extensions 100 making it selfstarting on an elliptical path 106 when poles 102 are energized with split-phase current. The motion of the arm is used to control a clock escapement mechanism 107, 108. The arrangement of Fig. 1 may be adapted for displaying an object by replacing the metal ball 13 by a platform carrying a short-circuited ring, the supporting arm and supports for the base 11 being resilient to produce an irregular motion. In another device the electromagnets are concealed in a stationary bottle around which a suspended bottle gyrates. The pendular motion may be produced by a ball rolling in a closed track on an inclined plane and the restoring force may be other than gravity.

Abstract: 554,435. Calculating devices. KRISTAL, R. M., (trading as AMERICAN HYDRO MATH CO.). May 20, 1941, No. 6474. Convention date, May 20, 1940. [Class 106 (i)] An apparatus for determining hydrostatic data of ships under various loading conditions, wherein the load and its vertical distribution are reproduced, is characterized by the combination of means responsive to the weight of said load, means responsive to the vertical distribution of said load, an indicator and means connecting said two first mentioned means with said indicator for causing the latter to indicate the true metacentric height of the ship. A platform 14 shaped and marked to the sectional elevation of the ship is supported by two bars 20, 21 pivoted to levers 22, 23 and to bell-crank levers 28, 29. A weight W representing cargo or stores, put on the appropriate part of the platform, depresses one or both of the bars to raise one or both of the counterweights 34, 35 and through toothed racks 40, 41 to rotate drums 36, 37 calibrated in draught fore and aft. The counterweights are connected by bar 47 which through a toothed bar rotates drum 51 calibrated in tons to indicate total displacement. A bar 52 rigidly carries another counterweight 53 moved transversely when the platform is tilted by extra loading either near the keel or near the deck, weight 53 operating lever 54 which points to one of a number of curves indicating the metacentric height and hence the stability of the ship under the loaded conditions. The counter-weights may be replaced by springs.
