Abstract: 866,239. Hydraulic pit props. HOESCHWESLFALENHUTTE A. G. June 5, 1957 [June 21, 1956], No. 17922/57. Class 20(2) The extension and collapse of an hydraulic telescopic pit prop is controlled by a valve 2 in the piston head 18 controlled by liquid under pressure in ducts 1, 9. Differential pressure on the head 4 and in an annular space 3 of the valve 2, produced when liquid is supplied to the pipe 1 raises the valve against a spring 5 and connects the duct 1 by passages 2a, 3, 6 the prop pressure chamber 7 to extend the prop. Pressure in the chamber 7 acts on the surface 35 of the valve 2 to reclose it. Fluid from the chamber 13 at the other side of the piston head flows through passages 12, 34 and out through the duct 9. The prop is collapsed by supplying liquid to the duct 9 which acts on the surface 10 of the valve 2 which is raised to connect the chamber 7 again to the duct 1 which is connected to exhaust, liquid also flows by the passage 12 to the space 13 to raise the piston. Two spring safety slide valves 15, 16 are provided in the piston head 18 both adapted to connect the chamber 7 to the chamber 13 at a selected pressure. In the valve 16 the pressure fluid passes through an axial passage in the valve to act on a surface 30 at the lower end of the valve.

IPC: E21D15/44
Filed: 1917-12-04
Abstract: 120,988. Graham, E., and Bowman, G. Dec. 4, 1917. Jacks.-The ram of a fluid - pressure - actuated jack for motor-vehicles is returned by fluid pressure or by suction. The space 16, Fig. 1, between the outer wall of the ram 3 and the inner wall of the jack casing 4 is closed by glands 14. 15, and fluid under pressure is admitted to this space by the port 17. The ram is actuated by fluid admitted through the port 22, and, during its outward movement, the fluid in the space 16 is forced through the port 19 into the cylinder 18, where it compresses the spring 21 and is retained until it is desired to return the ram. The cylinder 18 may be dispensed and fluid under pressure from a pump may be used to return the ram. In a modification, the port 17 is dispensed with and the ram is returned by connecting the port 22 to a vacuum chamber. The pressure within the jack may be maintained by a valve on the supply pipe when the pressure supply is cut off. The necessity for accurately boring the jack casing 4 is avoided by arranging the packing-gland 15 so that it bears on the outer wall of the ram below the end of the casing. Specification 115,724, [Class 79 (iii), Motor-vehicles, Arrangement &c. of parts of], is referred to.

Title: Apparatus for reading coded indicia in the form of perforations
Filed: 1961-05-19
Abstract: 937,348. Sensing statistical records. CUMMINS-CHICAGO CORPORATION. May 19, 1961 [May 20, 1960], No. 18280/61. Class 106 (1). A device for sensing patterns of perforations in a record comprises a pivoted head 19, Figs. 3, 5, carrying an array of sensing pins 88 and a pair of electric contacts controlled by each pin, the arrangement being such that when the head is brought down on the record the pins either pass through a perforation or are displaced by the record to open the corresponding contacts. The record, which is a film strip, is placed on a carriage 18 normally urged to the loading position (Fig. 3) by a band 60 and spring pulley 58. The record has two holes adapted to engage over locating pins 39, 40, side guides 45, 46 being provided to facilitate the placing of the record. When the record is properly mounted on the carriage it is pushed under the sensing head by hand. A switch SRS closes at the end of the stroke to energize a rotary solenoid 102 which pulls down a link 106 by means of a crank to bring the head down on the record. A locating dowel 131 on the head enters a socket 130 on the carriage during this motion ensuring an exact register of the carriage. A pair of card levers 114, 115 is also provided which have cam surfaces 129 adapted to bear on the record on the carriage and allow switches RSR and RSL to close. In the absence of a record these switches remain open and the solenoid 102 cannot be energized. As the sensing head comes down it closes a switch HDS, Figs. 3, 4 to energize the contacts. The array of sensing pins (five rows and eleven columns) are each connected to a block 90 in which the end of the top contact spring rests. When a sensing pin rises the corresponding contact is broken. After the sensing operation the solenoid 102 is de-energized to allow the head 19 to rise. This releases the carriage which runs back and strikes spring-loaded buffers 65, 66. An ejector plate 70, pivoted at 68, has two arms 71, 72 underlying the record and during the slight overshoot of the carriage allowed by the buffers a depending lug 74 strikes a stop 75 thereby tilting the ejector so that the arms lift the record off the locating pins 39, 40.
