Patent DE-2512138-A1 (DE)
Title: Mechanical speed control for engine - has vacuum servo in throttle linkage to control torque
Inventor: WEIL WOLFGANG
IPC: B60K31/06
Filed: 1975-03-20
Abstract: The throttle linkage from the throttle pedal (17) to the throttle valve (3) is formed by two telescopic shafts (9, 15) which are joined by a vacuum servo cylinder (10). The input side of the vacuum servo is linked to a venturi jet (7) in the throttle manifold so that an automatic speed control is obtained. For every steady setting of the accelerator pedal the vacuum servo provides a set level at a set engine speed. As the engine speed is altered when the vehicle runs up and down inclines, the vacuum level alters. This has a correcting effect on the throttle linkage so that the throttle valve is automatically altered to maintain the engine speed, without the pedal position being moved. The driver can thus drive at a set speed without having to alter his foot position.
Patent DE-2513041-A1 (DE)
Title: Method for detecting changes in machinery running condition - involves use of ultrasonic receivers for determination of shift in frequency pattern of machine
Inventor: SCHAEPER ELARD
IPC: B65H63/032
Filed: 1975-03-25
Abstract: The method enables changes of state, vibration or other movement in vessels containing liquids in rotating machinery or in pipelines, tubing and electric conduits, to be detected. The principle is based upon an ultrasonic receiver operating in the frequency range above 25kHz. The detector can either be fastened to that part of the machinery where movement is occurring or to a stationary part. The pick-up can be fixed to the wall of vessels to detect flow of liquids or even point of boiling or several detectors can be used, each tuned to certain resonant frequencies naturally occurring in the system under observation. Any changes in the state of motion will show as modifications to the frequency spectrum.

Title: Barbed strip for barrier against military vehicles - pressed from steel strip with barbs extended on tensioning
Inventor: WEISS ROLF
IPC: E01F13/12
Filed: 1975-06-10
Abstract: The barbed strip is made by pressing openings into the edge of a metal strip. The zig-zig shaped strip can be placed as a flat material and the radially outwards spreading barbs are generated simply by stretching the strip as it is wound out. The barbed material is readily picked up by the wheels or sprockets of the vehicles attempting to cross the barrier. The strip has basically a zig-zig shape (1a), parts being at an acute angle (alpha) relative to each other. The permanent barbed arrangement is obtained by the mutual relative twisting of the connecting parts (3, 4) of the zig-zag shape and hence there are formed barbs (5, 6) which project outwards.

Inventor: OELTER HEINZ
IPC: B01D53/50
Filed: 1975-07-09
Abstract: The appts. for scrubbing gas enriched in SO2, F2, NOx, N, CO2 and O2, uses a scrubbing liquor contg. () lime and (b) acids and/or salts of the halogen gp., N or P forming soluble Ca salts, which can be exchanged with SO2 in neutral or slightly acid medium and reform water-soluble Ca cpds. in alkaline medium. HCl and/or HCOOH are pref. These compsn. can be used as additives in CasO4 prodn. and (NH4)2SO4 can be produced from them by exchange with NH3, e.g. in liquid form. Carbonate incrustation in the scrubbing equipment is avoided, without detriment to the intensity, e.g. of SO2 absorption. Change of the scrubbing medium allows the prodn. of, e.g. artificial fertiliser (NH4)2SO4 instead of CaSO4. Suitably the appts. includes a scrubber, water separator, ventilator, oxidn. vessel and settler. Additives for CaSO4 prodn. pref. are added to the liquor in the settler and liq. NH3 to the liquor being recycled from the settler to the scrubber.

Title: Rotary piston engines sealing equipment - iisss used with rectangular piston profile, and seal groove is of X:section
Inventor: ESCH PAUL VON
IPC: F01C19/10
Filed: 1975-10-06
Abstract: The sealing equipment for rotary piston machines with rectangular profile pistons, rectangular x-section seal grooves, consists of lengthwise elastic sealing strips (30, 31, 32), one or more for each straight length of sealing groove. Lengthwise elasticity is achieved by making deep cuts (E) into the strips, alternately from top and bottom. The number of cuts is chosen so that the increase in length of the strip between ambient and working temp. equates to the sum of cut widths. Under end press., the strip thus functions as though it had not been cut. Sealing is improved by leaving the ends (x) of the strips uncut, and by having several strips with the cuts staggered side-by-side in each groove. Leaf springs under the strips press them against the casing face.
