Abstract: 1123030 Seats REINHARD HORNLEIN K G 12 Nov 1965 [14 Nov 1964 23 Dec 1964 28 Jan 1965 23 Mar 1965 24 Mar 1965] 48147/65 Index F2S 31 [Also in Division B8] A lifting unit, Fig.1, for adjusting the vertical height of a table for chair comprises a cylinder 1 with chambers 2, 3, 4. Chamber 2 contains gas under pressure and is bounded by a floating piston 7. Chambers 3 and 4 contain oil and are separated by a fixed wall 9. A guide 10 with a rod 11 is slidingly arranged in chamber 4. Connection between the chambers 3, 4 is through ports 12, 13 controlled by a slide valve 15 operated manually by a bar 21. In the position shown the chamber 3 is isolated from chamber 4 so that the unit is locked hydraulically. When the valve 15 is moved down so as to connect ports 12, 13 the gas in chamber 2 expands forcing the piston 7 down and transferring oil from chamber 3 to chamber 4, oil also passing from above the guide 10 to below it through a port 22, which may be a throttle port. So that chamber 4 can accommodate the additional oil the rod 11 is forced downwards. The guide 10 may have one or more one-way valves which permit rapid passage of oil during lowering. The chambers 2 and 3 may be separated by a solid or hollow ball 27, Fig.2 (not shown) of resilient material. As shown in Fig. 7 the chambers 2 and 3 may surround the chamber 4 as an outer cylinder. The chambers 2 and 3 may be larger in diameter than the chamber 4, Fig. 8 (not shown). Other types of valve may replace the slide valve 15 to control passage of oil from chamber 3 to chamber 4.

Patent DE-2152869-A1 (DE)
Title: Softening of thermoplastics - around inserted component using heat generated by friction
IPC: B29C48/09
Filed: 1971-10-23
Abstract: A method of softening or smelting thermoplastics consists of heating a metal component by continuous friction, the heat being transmitted from the metal component into the adjacent thermoplastics; the generation of heat by friction is continued until the desired degree of smelting or softening is achieved. In a typical arrangement, a metal component, e.g. a threaded bush, is inserted in a pre-formed blind hold in the surface of the plastics; then a high-speed revolving pin is applied into the hole of the bush, frictional heat being generated between the conical end of the pin and conical seating at the base of the metal recess. The axial pressure applied by the pin serves to bring the component to its desired depth of penetration into the plastics.

Title: Stretched elastic sieve supported on frame - gives predetermined sag during vibration increasing vibration amplitude
Inventor: WEHNER ALBERT
IPC: B07B1/46
Filed: 1972-08-16
Abstract: A sieve is made of elastic material, as described in 2126276, stretched over a supporting frame which exceeds, in each field of the sieve, the dimensions of the corresponding portion of the sieve itself by an amount equal to the intended stretch. The sieve therefore does not fit onto the frame until it is stretched and assembled on it. In the present patent, which is an addition, the difference in length between the elastic sieve and its supporting frame which determines the stretch is so selected, in conjunction with the residual tensile cross-section in the perforated zone, and the elasticity or shore hardness of the material used for the sieve, that wmeh the predetermined depth of material is placed upon the sieve and the sieve is accelerated or vibrated, a desired concave shape of sieve is achieved in each sieving zone. The amplitude is considerably increased when the sieve is vibrated. In an example using 50 mm depth of hard stone on a 250 mm length with supports at 170 mm intervals a maximum sag of 8 mm during vibration was achieved.

Patent DE-2331982-A1 (DE)
Title: Hydraulic system for medical apparatus - oil-tight oil supply container box for larger vol. than oil received
Inventor: MAGNI ALBERT
IPC: F15B1/26
Filed: 1973-06-22
Abstract: The box is connected to the pump via a pressure valve with a compressed air container, and via a suction valve to atmosphere to produce the required air pressure for actuation of the pneumatically controlled valves of the apparatus, using the change of the air volume owing to the changing oil level. The elements can be moved with the aid of the apparatus valves and with a central control, which includes the control elements for actuation of these valves and the connecting elements between the control elements and these valves, and also the oil reservoir, which is in the oil circuit, while compressed air is used to transmit the pressure required to control the pneumatic apparatus valves. Preferably the oil reservoir is an oil feed container and an oil drain container which are interconnected via a valve flap controlled by a level regulator such that when a max. difference of level is reached between the two containers, the valve opens, and the feed oil is fed to the feed container and the drain oil is taken from the drain container. The pneumatic and hydraulic pressure sources are combined in the apparatus.

Title: Gas pressure regulator - has built in indicator which shows maximum operating pressure condition to avoid overload of the control diaphragm
Inventor: HERBIG VOLKER
IPC: G05D16/06
Filed: 1973-10-02
Abstract: A ring seal poppet is mounted on a central valve spindle and seats against an annular insert to separate input and output chambers. Output pressure is transmitted to the underside of the control diaphragms through a pick-off tube located in the outlet chamber. An intermediate diaphragm separates the inlet from the control chamber. The regulator setting is effected by pre-loading a bias coil spring against the control diaphragm using a threaded nut. For visual indication the control diaphragm displaces a pin screwed into a stem, the top surface of which is viewed through a transparent cap. ON and OFF markings are located on the outer surface of the cap.
