Title: Bearing shell for a hydrostatic gas bearing and a method for its production
Inventor: TITTIZER GABRIEL DIPL ING
IPC: F16C32/06
Filed: 1982-08-13
Abstract: In order to overcome material and vibration problems, a bearing shell for a hydrostatic gas bearing is proposed which consists of a porous material and whose surface coating (7) is more highly compressed on the inside of the bearing shell (3) than the remaining coating of the bearing shell. In this way, only the compressed coating takes over the constraining function of the bearing shell and the reduced storage effect of this coating prevents oscillation of the supported shaft (1). In particular, it is proposed to compress the inner surfaces of the bearing shell by rolling, and subsequently to expand the surface pores by electrical corrosion up to a defined pore opening again. In this way, the supporting capability and the vibration properties of the bearing can be set exactly. <IMAGE>

Title: Multiple fuel control valve assembly
Inventor: SPRICK ELLIS HARVEY
IPC: F02M13/06
Filed: 1982-10-18
Abstract: A fuel mixing valve is described with a plurality of slides (37, 38) which control the feed of main and secondary fuel into a valve mixing chamber (25). The octane rating of the fuel charge can be temporarily increased during engine acceleration periods so that the engine can be manufactured with a higher compression ratio for optimum efficiency but is nevertheless capable of functioning with fuel having a relatively low octane rating. The slides (37, 38) controlling the fuel feed may be fixed on a common shaft (34) for simultaneous movement or on separate carrying devices for different slide movement which is brought about by an engine control device. A fuel mixing valve for use in conjunction with the parts of the second stage of a two-stage carburettor is also described. <IMAGE>

Title: Sealing pipe connecting plug-in system
Inventor: MAYER HERBERT
IPC: F16L21/08
Filed: 1983-02-02
Abstract: The invention relates to a sealing pipe connecting plug-in system for fluid or gaseous media, in which a plug-in fixed, sealed pipe connection is achieved by simple deformation of the pipe ends using a seal, which pipe connection is also able to absorb the thermal expansion of the pipe and to compensate for torsional stresses. This is achieved according to the invention in that a pipe end having a fold or a sprung ring in an existing groove is pushed so far into a pipe end or connecting part which is deformed and provided with a seal that said pipe end or connecting part projects beyond the fold or ring and holds the connection by means of complete or partial rolling or bending in, and prevents said connection being released. Figure 1 shows an exemplary embodiment of the invention. The advantages which can be achieved are the rapid, permanent and sealed connection of pipes in a manner which saves installation and test time and aids, by means of which individual influences on sealing, thermal expansion stress and torsional stress are considerably reduced. <IMAGE>

Title: Hydraulic brake and steering brake system
Inventor: BENDER ALFRED
IPC: B60T11/21
Filed: 1983-02-19
Abstract: The invention relates to a hydraulic brake and steering brake system for motor vehicles having two main tandem cylinders (1, 2) which can be actuated by a pedal individually or together and have in each case one working chamber (7, 8) near to the pedal and one (9, 10) remote from the pedal. Wheel brakes (29, 30) of a vehicle axle which can be subjected to steering braking and a valve arrangement (33) which can be controlled by the main cylinder pressures are connected to two mutually corresponding working chambers (7, 8). In addition, wheel brakes (48, 49) of a wheel axle which can not be subjected to steering braking is connected to the valve arrangement (33). Normally blocked valve passages between the working chambers (7, 8), near to the pedal, of the main tandem cylinders and the wheel brakes (48, 49) of the vehicle axle which can not be subjected to steering braking can be controlled by means of the valve arrangement (33). With a view to a simple design of the valve arrangement (33) and a reduction in the sealing friction it is proposed that the working chambers (9, 10) which are remote from the pedal should be hydraulically connected to one another and to the control connection (39) of the valve arrangement (33), and that a wheel brake (29, 20) of the vehicle axle which can be subjected to steering braking should be connected to each working chamber (7, 8) which is near to the pedal. <IMAGE>

Patent DE-3314510-A1 (DE)
Title: Sowing template
IPC: A01C7/02
Filed: 1983-04-21
Abstract: After much deliberation on the designation of my appliance, I have decided to call it a "sowing template". This designation corresponds to the intended use, and in particular this appliance is intended to ensure an equal spacing and an equal depth of the seed in the ground when particular types of vegetable are being sown. Seed grains of radishes and the like are especially suitable for this. These are fixed in the kernel and can easily be distributed individually into the 4-mm holes of the sowing template, so as then to be pressed into the garden soil with the hole-making appliance. The division of the holes in the sowing template ensures an equal spacing and rows. However, the circumference of the fully grown vegetable must be borne in mind. It does not matter whether a spacing of 5 to 10 or 15 cm is needed. If required, one or two rows must be skipped in both directions. The spacings of the rows are always indicated on the seed packets.

Title: Method for measuring the longitudinal speed and the length of workpieces
Inventor: DEPPE GERD-JOACHIM DR RER NAT
IPC: G01P3/50
Filed: 1983-06-16
Abstract: The invention relates to a method for measuring the longitudinal speed, length or path length of elongated workpieces moving about their longitudinal axis and in the direction of their longitudinal axis, by measuring using the optical differential Doppler method with start and stop signals triggered by the workpiece and a display of the longitudinal speed and the workpiece length passed through. In order to improve the accuracy of measurement of a measuring method, for example for the case in which the workpiece in addition to rotating in the measuring direction also rotates about its longitudinal axis, it is proposed that a switch is actuated by the workpiece at a defined distance behind the start signal in the direction of the workpiece longitudinal movement, forming as a result an intermediate length which is compared with the defined distance, corrected and used to correct the subsequent measured longitudinal speed and length passed through, or to adjust the path measuring direction. <IMAGE>

Patent DE-3325245-A1 (DE)
Title: Prestressed support post
Inventor: BERGER WOLFGANG DR ING
IPC: E21D11/14
Filed: 1983-07-13
Abstract: In mining, tunnelling and gallery construction, a support system is necessary during the driving. On account of the immediate bearing capacity, steel is especially suitable as a support material. The correct choice of the driving cross-section makes it possible to keep the bending-moment stress very low and to remove the loads mainly via normal forces (compressive forces). The bearing capacity of the steel is thus only half utilised, since the tensile strength remains unutilised. In the case of a hollow cross-section which is set under internal pressure, the steel is stressed in tension. If the cross-section is then loaded in compression, the bearing capacity is determined by the overcoming of the tensile stresses produced by the internal pressure and the permissible compressive stresses. Since the permissible tensile and compressive stresses of the steel are the same size, it is possible to reduce the requisite steel cross-section almost by half.
