Abstract: 383,283. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Platen-Munters Refrigerating System Aktiebolag ; 2, Norrmalmstorg, Stockholm.) July 29, 1931, No. 26424/32. Convention date, Aug. 13, 1930. Divided on 382,654. [Class 29.] Absorption systems.-In continuous-cycle inert gas systems wherein the circulation of liquid is effected by gas put under pressure periodically by means of liquid columns and then released, the conduit conveying liquid from a low pressure chamber to a high pressure chamber is divided to provide a plurality o f liquid columns in series, whereby the height of the apparatus is reduced. The generator 10 is divided into two chambers as shown and expelled vapour passes from the upper chamber to the rectifier and condenser through a pipe 11. The lower chamber, constituting the " pumping " chamber 20, communicates with the absorber 16 by a pipe 21, and is also connected through a " valve " pipe 23 and a U-pipe 25 with the vapour pipe 11. Two pipes 24a, 24b forming part of the circulation control extend from an intermediate chamber 31 to the lower and upper chambers of the generator, and the chamber 31 communicates with the vapour pipe 11 by a pipe 32. On heating the " pumping " chamber liquid is forced into the pipes 25, 24a to form columns therein, and rises into the absorber through pipe 21. The liquid rises in chamber 31 and seals the end of pipe 32, and pressure is built up until the seal in the " valve " pipe is broken, when pressures are momentarily equalized and liquid flows from the upper generator chamber through the pipe 24b, chamber 31 and pipe 24a to the " pump " chamber.

Abstract: 1,024,999. Selective printing. ANELEX CORPORATION. June 26, 1964 [Oct. 25, 1963], No. 26429/64. Heading B6F. Type - wheel machines; rotary type selection; record controlled input; multiple type selection; power assisted type actions.-A selective printer comprises a plurality of rotatably mounted type wheels 10, co-operating with type selecting gears 14 drivingly connected to a drive shaft 18 through overrunning clutches to present selected characters at a printing position. In operation the type-selecting cycle is initiated by a motor 108, which drives a cam-shaft 106 whereby a cam 142 releases a bail 150 co - operating with short teeth 152 on the gears 14, which bail checks the initial alignment of the type wheels 10, and subsequently a cam 140 lowers a stop comb 80, whose teeth 83 co-operate with stop pins 46 on the gears 14, to release the latter for rotation with the drive shaft 18, which starts to rotate when a cam 122 on continued rotation of the shaft 106 disengages a pawl 124 from obturating engagement with a pin 130 on a one-revolution clutch 112 driving said shaft 18. Mounted on said shaft 18 and associated with the type wheels 10 is a rotary switch 94, having a roller 98 which momentarily closes an associated circuit to indicate the arrival of a corresponding type character at the printing station. The selected type characters are indicated by punched holes in a record card, whereby the punched holes cause establishment of electrical circuits (Fig. 6, not shown) incorporating solenoids 78, which solenoids release latches 70, co-operating with pawls 50. The displaced pawls 50 intercept the associated type-wheels 10. A completion of one revolution of the shaft 18 all type-wheels are set and the shaft is arrested by the pin 130 engaging the pawl 124. Hammer-impression arrangements.-A single hammer (not shown) is displaced to effect impression of the line of selected characters. Type-wheel resetting arrangements.-Following impression a cam 138 on the rotating shaft 106 pivots a bell-crank 60, which raises a bail 52 to raise the pawls 50 out of engagement with the gears 14 and the cam 140 raises the stop comb 80 so that its teeth 83 may engage the stop pins 46 on the gears 14, which begin to rotate when the shaft 18 is engaged by the clutch 112 on pivoted release of the pawl 124 engaging the pin 130. The stop comb 80 is further associated with an index arm 90 cooperating with an index pin 102 on the rotary switch 94 so that on completion of one revolution by the shaft 18 all type-wheels 10 and the switch 94 are reset to their original positions. Finally the cam 142 raises the bail 150, which when it engages all short teeth 152, closes a switch 154 to produce a signal, which may be used to initiate a fresh typesetting cycle. Types, discs and printing surfaces.-Each type-wheel has a fount of characters arranged peripherally on gear-teeth 12 and the characters are formed on lands 16 of the teeth.

Title: Hydraulic brake
IPC: B60T11/22
Filed: 1938-09-12
Abstract: 521,441. Hydraulic brakes. BOLSEZIAN, G., Sept. 12, 1938, No. 26626. Convention date, Sept. 10, 1937. [Class 103 (i)] A master cylinder for hydraulic brake transmission comprises a valve 25 in the passage 4, 11 leading to the pipe lines and brake cylinders, this valve having a lost-motion coupling to a piston 7 subjected to the pressure in the brake cylinders and of greater area. than the valve and subjected also to the pressure of a spring 10 which is weaker than the brake return springs. Thus the valve 25 and piston 7 are raised when the main piston 5 is operated to apply the brakes and return after release of the brakes and the piston 7 then continues to exert a slight pressure in the pipe lines due to the spring 10. Small contractions of the liquid in the pipe lines are made up by movement of the piston 7 but further contractions after the piston has reached its stop 13<SP>1</SP> are compensated for by flow from the reservoir 2 through the port 3 and valve 25. The cylinder acts as a pump for filling the system, the valve 25 then serving as the outlet valve which during the return stroke of the main piston liquid is supplied to the cylinder from the reservoir through a port 20, grooves 21 in the piston and past the cup washer 41. In a modification the main piston is of the same diameter as the cylinder substantially throughout its length except for an annular groove adjacent the grooves 21. This annular groove connects with a rearwardly extending groove by which and an annular groove in the cylinder, the port 20 communicates with the grooves 21 in any position of the piston. The piston in this case has a cup washer at the rear as well as at the front end instead of the arrangement of fixed rubber washers 32, 33 and metal ring 31 shown in Fig. 2, In a further construction, the piston rod 18 passes through a single fixed rubber sealing disc and grooves such as 21 extend the whole length of the piston. A modified form of the valve 25 comprises a flexible bell-shaped member which seats at its edge around a port such as 4 the yielding of this valve member allowing the necessary lost-motion between the piston 7 and the valve. According to the Specification as open to inspection under Sect. 91 liquid is supplied from the reservoir to the cylinder during the return of the piston through a non-return valve, the grooves 21 being dispensed with and a liquid seal being provided for the piston by an annular groove in the cylinder communicating by a port with the reservoir. This subject-matter does not appear in the Specification as accepted.
