Abstract: 1,197,735. Bearings. T. GEFFNER. 5 Oct., 1967 [12 Oct., 1966], No. 45374/67. Heading F2A. A rectilinear-motion bearing has a number of spaced-apart endless paths with recirculating rolling elements therein. Each path has radially-spaced inner and outer longitudinal portions which are connected by curved endportions, and has a movable member which is located between said portions and is engaged by the rolling elements. The longitudinal portions are formed in inner and outer sleeves which are in fixed relationship with respect to each other to form a carrier. In an embodiment, a shaft 12, Figs. 2 and 3, is mounted for rotational and rectilinear-motion in a bearing 10 which is provided with a carrier 16 located between said shaft 12 and an outside member 14. The carrier 16 has an inner-sleeve 18 and an outer sleeve 20 connected at their ends by means of caps 22. Re-circulating balls 32 are provided and are in engagement with the shaft 12. Paths are formed between a movable loadtransfer member 34 and the shaft 12, and between the member 34 and the outside member 14. Part-circular paths are provided to connect the load-bearing balls to the non-loadbearing balls. The carrier 16, having apertures 38 therein, also forms a cage for balls 36 which are positioned between the load transfer member 34 and the outside member 14. The apertures 38 are located intermediate slots 26 which form part of the paths for the balls 32. In a modification the balls 36 are replaced by rollers 136, Fig. 5, two of which are located intermediate each row of balls 132 positioned between the loadtransfer member 134 and the outside member 114. The rollers 136 are received by recesses 126, Fig. 7, formed in sleeves 120 and guide the re-circulating balls 132.

Patent GB-482197-A (GB)
Abstract: 482,197. Automatic accordions and organs. VERBEECK, J. Sept. 21, 1936, No. 25609. [Classes 88 (i) and 88 (ii)] In an accordion 2 having notekeys 4 played automatically under control of a perforated paper tunesheet 15, the interior of the bellows 2 is connected to means, such as the suction side of a pump, for maintaining a negative pressure therein. The accordion may be mounted on an automatic organ played by the same tune-sheet. Striking-pneumatics 10, directly linked to the note-keys 4, are operated by compressed-air supplied by a pump, the inlet side of which maintains the bellows 2 exhausted for energizing the reeds. Pipes 60 from the striking-pneumatics enter compartments 50, from which further pipes 65, 66 lead to corresponding sounding- elements or pipes of the associated organ. Electro-pneumatic control is effected through spring-loaded feelers 20 which pass through the tune-sheet perforations, allowing electric contacts 28 to close, thus selectively energizing electromagnets 30, which lift disc-valves 32 to open atmospheric vents to the upper sides of diaphragms 41, the under sides of which communicate with the pressure-chest 36 through passages 39. The diaphragms 41 thus lift, closing atmospheric vents 43 and opening pressure-inlets 40 to relay-chambers 40a, . pressure in which lifts diaphragms 56 for cutting off the atmospheric vents 55 to the striking- pncumatic chambers 50 and communicating the chambers at 54 with a pressure-chest 62, thus causing the note-keys 4 to be actuated. Means may be provided to sound the organ or accordion independently.

A gas turbine plant comprising a compressor, combustion chamber and gas turbine has means for introducing an additional fluid into the working fluid downstream of the air compressor. Means are also provided to reduce the compressor output or to increase the flow cross-section of the turbine at the same time as additional fluid is supplied to the working fluid, so as to satisfy overload conditions on the plant without surging of the compressor. The plant shown in Fig. 1 comprises an air compressor 3, combustion equipment 12 and a turbine 13 and means 1 are provided for introducing additional fluid into the air stream passing through the duct 2 from the compressor to the combustion chamber. The means comprise a series of nozzle members 9 through which the fluid is discharged. The direction of discharge of the additional fluid may be varied by rotating the nozzle member 9 about its axis, the nozzle member being then secured in position. A portion of the air flowing in the duct 2 may pass through a passage 14 surrounding the gas inlet duct to the turbine, the air discharging into the turbine as indicated at 8, this air serving to cool adjacent parts. A portion of air constituting primary combustion air may pass to the combustion chamber so that no additional fluid is introduced into this air, a flow control valve being disposed in the duct 2 upstream of the additional fluid injection device. The means for adapting either the compressor or the turbine or both to the load may be adjustable compressor impeller blades or adjustable turbine rotor blades.

Abstract: 1484827 Temperature control MULTI-STATE DEVICES Ltd 28 Nov 1975 [29 Nov 1974] 49048/75 Heading G3R [Also in Division G4] A heater control system comprises a temperature discrimination apparatus (see Division G4) for determining when a predetermined temperature has been reached, such apparatus comprising, as shown in Fig. 3, a switching device Rl exhibiting regenerative switching action at a power level dependent upon temperature and connected in series with a resistor R2 across an A.C. supply, and a switching device D1, a silicon unilaterial device as shown, exhibiting regenerative switching action solely in response to a preselected power level. In operation, the point at which R1 switches varies from 90 degrees to 0 degrees proportionally as temperature increases, and the point at which Dl fires is set by resistor R3. As long as the temperature is below the predetermined temperature, D1 fires before R switches and a sharp pulse appears across resistor R6. Similar action occurs on each successive cycle and thus a series of pulses are applied to fire a SCR Ql which controls the firing of a triac TR in series with the heater H. When the predetermined temperature is reached R1 switches first and thus a diode D2 becomes forward biased thereby lowering the voltage across R3 so that D1 does not fire and no pulses are applied to the SCR Q1.
