Title: Improvements in apparatus for teaching card games
IPC: A63F1/06
Filed: 1932-11-19
Abstract: 399,999. Teaching the playing of card games. ELLSWORTH, F. P., 410, Central Park West, New York, U.S.A. Nov. 19,1932, No. 32745. Convention date, Nov. 19, 1931. [Class 132 (ii ).] Apparatus for teaching card games comprises a sheet with a plurality of hands of cards indicated thereon, a mask overlying the sheet, means whereby at least one of the hand indications is continuously exposed through the mask, and means carried by the mask to conceal certain of the other hand indications and operable to expose single card indications from said certain hands in the correct order of play. Sheets 13 on which are printed representations of playing cards, and other data, are removably stacked on hooks 12. The top sheet is covered by a mask 24 comprising two plates spaced apart and supported on a rod 20 which can be adjusted in brackets 16, 17 to allow different numbers of sheets to be placed beneath the mask. By unscrewing a nut 22 the rod 20 is freed to allow the mask to be swung over while the sheets 13 are changed. Various apertures are formed in the mask 13 by holes in both its plates. Initially, the bottom line of the representations 65, comprising the player's band, is seen through the " South aperture 35. A slide 31 controlled by pawls 33 is pulled down step by step to expose the sequence of bidding 64. The player then moves the mask one step along the rod 20, the movement being controlled by a pawl 62 engaging teeth 61. The player's hand is again exposed at 35 and dummy's hand becomes visible through the " North aperture 36. The player now turns a knob 47 in an anticlockwise direction, thereby rocking a shutter 40 pivoted at 41 to expose through the " West " aperture 37 the card which is supposed to be led from that position. The player then decides the card " dummy should play and turns the knob 47 a step further to reveal the card played from the " East " position through an aperture 38. He finally decides which card he would play and then closes the apertures 37, 38 and moves the mask 24 one step along the rod 20. The third line of the representations 65 is now visible through the aperture 35 and the card which should have been played can be found by noting the blank space in that line. Similarly, the card which should have been played by dummy is indicated, and the tricks which ought to have been made are shown at an aperture 39. The process is then continued. The " West " and " East cards are represented at 66 and 67 on the sheets 13 and the mask 24 is locked when the shutter 40 is out of the position in which it obscures both apertures by a detent 58 which is forced into engagement with the teeth 62 by a cam on the spindle of the knob 47.

Abstract: 1,151,846. Cleaning of gas filter elements. J. PAUSCH. 21 July, 1966 [22 July, 1965], No. 32822/66. Heading BIT. Inward flow filter elements 8, of flexible material, are cleaned by directing reverse flow gas into their open ends through nozzles 38 (Figs. 3, 4, not shown) which are so shaped as to accelerate the gas to supersonic velocity, thereby inducing waves (72) in the elements 8. Compressed air at 80 p.s.i. is delivered to each nozzle in turn, whereby filtering may continue through the remaining elements 8, by means of a power rotated distributor valve 32, which comprises a rotor plate having an elliptical aperture (56) (Fig. 2, not shown) which comes into alignment with each of a number of. outlet ports, connected to the various nozzles in turn. The velocity through a nozzle 38 builds up so that normal reverse flow precedes the supersonic shaking. The inlet conduit 18 for gas to be filtered, comprises a main outlet 18a and a further outlet at the end of downward turn 18b. A defector 18c directs the gas upwards, upstream of outlet 18a, and larger particles thus reach the downward turn and are carried with a portion of the gas out of lower opening 16 of the housing. A suction means on the outlet side 24, 26 of the filter draws the remaining gas through elements 8. Elements 8 are internally supported and secured by ring clips (30) (Fig. 3). An example gives the dimensions of tube 38 and the frequency of the resulting waves.

Title: Improvements relating to apparatus for regulating coolant circulation in internal combustion engines
IPC: F01P7/16
Filed: 1963-08-20
Abstract: 968,073. Cooling systems for I.C. engines. DAIMLER-BENZ A.G. Aug. 20, 1963 [Aug. 30, 1962], No. 32959/63. Heading F4U. Apparatus for regulating coolant circulation in an I.C. engine having a thermostaticallycontrolled radiator by-pass comprises independent thermostatic regulating stages operative for progressively opening passages for coolant circulation at different coolant temperatures, at least one stage responsive at a lower temperature controlling a smaller passage cross-section than at least one stage responsive at a higher temperature. In the form shown, water is circulated between an engine 1 and a radiator 2 by a pump 7. At low coolant temperatures the radiator is bypassed by coolant flow through a pipe 8. When the temperature reaches a preset value, e.g. 75‹ C., a valve 12 controlled by a bellows 11 opens to allow a small flow of water from the engine outlet pipe 5 into the radiator through an opening 14 and the pipes 15 and 5<SP>1</SP>, the cross-sections at 14 and 15 being about 25% of that of the pipe 5<SP>1</SP>. At a higher temperature, e.g. 80‹ C., a bellows 9 actuates a double valve 10 to close off the by-pass 8 and open a passage having a cross-section of about 75% that of the pipe 5<SP>1</SP>, so that all of the water flows from the engine into the radiator. The flow of cold coolant into the engine is thus increased by stages. In cold weather only the narrower passage may be used.

Filed: 1931-11-28
Abstract: 383,749. Mixing-machines. LANGFORD, H., 96, Plymouth Place, Leamington Spa, and WINGET, Ltd., The Cape, Warwick. Nov. 28, 1931, No. 33033. [Class 86.] The pivoted skip of a concrete mixer &c. is raised by a hydraulic ram charged by a pump formed integral therewith, the discharge from the ram being controlled automatically from the skip through a valve whereby a jigging motion is given to the skip in its discharging position. The pump 11 is driven through intermediate gearing from a shaft 2 on which the skip is pivoted, and is fed through a pipe 20 from a reservoir. The ram discharges into the reservoir through a pipe 22 having two branches, one allows the fluid to return freely to the reservoir and renders the ram inoperative, the other is fitted with a valve having two bores 29, 30 of different diameters. The valve is controlled by a handle 28 on a shaft 27 which is also operated by linkage 32, 33, 35 when a projection 37 on the skip engages an arm 38. When this occurs the valve is rocked so that the ram discharges through the small bore 30, the pulsations of the pump then effecting a jigging movement of the skip. For lowering the skip, the valve is moved by hand so that the ram is discharged through the large bore 29 ; by rocking the valve to the position shown, the ram is operated to raise the skip.

The impedance selecting means 11 comprises a rotary wafer switch generally similar to that described in Specification 936,279, in which a number of contacts 20 and a common contact ring 34 are bridged by moving contact 29. The wafer 33 is mounted on the bottom of the switch by the interconnectors 36 being soldered to switch terminals 20a, the switching taking place within the switch 11. It is stated that instead of switch 11 a movable contact could rest directly on wafer 33, the switching taking place between the movable contact and portions 366 of interconnections 36. Wafer 33 is made of electrically non-conducting material such as stertite or alumina ceramic material and impedance elements 35 are cermet film resistors or made of carbon compositions formed by spraying, brushing, rolling, sputtering, vacuum depositing or screening. The ohmic value of resistors 35 may be adjusted by removing portions of the resistance film by a process such as sandblasting. Cermet interconnectors 36 are deposited on wafer 33 by the process used for depositing resistors 35. Two terminal points are provided on wafer 33 using the same cermet material used to form interconneotors 36. In a modification, Fig. 3 (not shown), the resistors have different geometrical configurations and in an alternative embodiment, Figs. 4, 5, 6 (not shown), the terminals of the switch 11 are bent parallel to the switch axis and pass through holes in the wafer and are soldered to the interconnectors on the underside of the wafer, the resistors also being on the underside of the wafer. In modifications of this, Figs. 7, 8 (not shown), instead of holes there are slots in the edge of the wafer or in the edge of a central hole in the wafer for the switch terminals. A plurality of circuit wafers may be stacked together.
