Title: Mine road support channel strut - has slotted apertures in strut end for bolt and driven wedge connections
Inventor: SMARRA GUENTHER
IPC: E21D11/24
Filed: 1975-09-09
Abstract: The Strutting for mine channel sections consists of bolts with end connections for adjoining sections formed from two slots per section to suit the channel stay and flange border prior to locking by wedges passed through the two slots. Each end connection consists of a strap (10) with the slots and an interposed piece acting as a channel spacer. The lengths of channel section between the slots act as guides for the bolts (6) resting on the stay exterior with their own end faces. Each guide has its allotted wedge (17) whose opposing surfaces lie in the guide and in the end of the bolt. Clamps are fitted to each strap link and bear against the outward endface of the respective channel section stay.

Title: Protection valve for trailer air brakes - has throttle to isolate brakes at set pressure difference for rapid venting and emergency braking
Inventor: UNGER HANS
IPC: B60T17/04
Filed: 1975-10-09
Abstract: The trailer brake supply line is fitted with a flow control valve which has a second input linked to the towing unit brake circuit. The valve has a spring loaded membrane which opens when the differential pressure between the towing unit circuit and the trailer brakes is greater than a set value. The valve then provides a control signal to the main supply manifold for the brakes so as to isolate the trailer brakes. The system provides a fast response to any sudden leaks in the trailer brakes. The trailer system is isolated so that the pressure drop is enhanced, without affecting the towing unit brakes. The emergency hold-off brakes on the trailer are thus activated faster.

Title: Prefabricated component assembled fence - has horizontal units matching flanged triangular posts section, and vertical plate battens
IPC: E04H17/14
Filed: 1975-11-20
Abstract: Fence is made up from fencing sections attachable to triangular-sectioned posts with a T-shaped fixture flange on one of their three sides. It is designed to be less resilient than the usual mesh fences, and to have vertically aligned bar elements, esp. near gates, so as to present an overall aesthetically acceptable appearance. Each of the fencing areas is made up from spaced horizontal shaped-section units (2), matching the posts (1) in cross-section; and plate sections (3), which are batten-shaped, fixed vertically to the horizontal ones. These are reinforced by bent sections (3b) running parallel to their longitudinal sides, and have fixture flanges (3a) lying in a single plane. Clamping units are used for connecting the shaped-section units to the T-shaped fixture flanges. The bend on the batten-shaped units may make up a triangular cross-section between the flat flanges.

Title: Grinder with rotary multi workpiece head - has feed rate transition to contact grinding wheel slowly
Inventor: DAKIN ROLAND PETER
IPC: B24B5/02
Filed: 1975-11-28
Abstract: The workpiece grinder head turns about a shaft. It has a number of workpiece holders at equal spacings about the shaft. The holders can move along a curved path when the head is turned about its shaft. A grinding device close to the head has a grinding surface close to the path to engage a workpiece passing along the path. The head is rotated rapidly at first to move one of the workpiece holders and its workpiece quickly to a position closely adjacent to the grinder. A following period of relatively slow rotation is imparted to the head to move the workpiece into engagement with the grinding surface. The head is prevented from rotating when one of the workpieces is in a grinding position, until grinding is concluded. A final stage of relatively rapid rotation is then imparted to move the holder and the ground workpiece away from the grinding device.

Title: Brake valve for limiting fluid pressure - has opposing valve bodies of pressure limiting and nonreturn valves
Inventor: BRUNNER RUDOLF
IPC: F15B13/01
Filed: 1975-12-29
Abstract: The brake valve is for limiting gluid pressure in a first pipe to which is connected a fluid-driven working unit. It comprises a non-return valve component (7) which allows unobstructed throughflow in one direction only, and a pressure-limiting valve component (8) which allows fluid to flow in the opposite direction only when opened by sufficiently high pilot pressure from a second pipe which is also connected to the working unit. A stationary plate (21) with valve openings (19,20) forms valve seats for the valve bodies (23,24) of the non-return and pressure-limiting valves on opposite sides, the two valve bodies moving in opposite directions to each other.

Title: Steel rings for bearings prodn. - by centrifugal casting with controlled cooling, and heating, followed by rolling to shape
Inventor: SOMMER KAREL
IPC: B22D13/00
Filed: 1976-03-04
Abstract: The prodn. of ring-shaped workpieces of hypereutectoid steel, which after hardening, contains low C martensite with a dislocation substructure, comprises cooling the hollow ingot, or a section of the ingot, obtd. by centrifugal casting, from the casting temp. to is not >100 degrees below the eutectoid transformation, and re-heating the casting to is not >100 degrees C. above the temp. of the eutectoid transformation.

Title: Gauge for measurement of gap between two rollers - has sensors pressed to rollers whose position determines size of gap
Inventor: MEYER ULRICH
IPC: G01B7/14
Filed: 1976-06-12
Abstract: The measured value of the gap is applied to a gap control device as the actual value which may be compared with a stored desired value. The gauge has an electromechanical pickup whose corresponding halves determine the position of the rollers by sensors. Two wiper arms (10, 11) carry at their free ends the sensors (16), and are hinged on a balance beam (12) mounted on a supporting bar (13). A spring (15) on the bar (13) presses the sensors to the rollers (20, 21), so that the two halves (22, 23) of the sensors change their position when the gap changes.

Title: Measurement of deformation properties of materials - using cycling device with compression relax components and means of interpreting signals
Inventor: GADDUM FRIEDBERT ING GRAD
IPC: G01N3/00
Filed: 1976-08-25
Abstract: Process for testing physical properties of material according to DT2522362 permits the measurement of the elastic and non-elastic, reversible and irreversible deformation properties of samples. These can be in solid, liquid or gaseous form. Their variation wrt the initial condition is measured. The purely elastic force component of deformation can be measured on the forward stroke or backward stroke. By variation of the compression time and the speed of measurement, a force spectrum can be measured which is dependent on the relaxation position of the various material components. The time-elastic force component is given by the difference between two force expressions or from the force increase on the return stroke or the force decline on the forward stroke for a stroke velocity of zero.

Title: Transmission of state of motor vehicle tyres, wheels and brakes - using two coupling coils on vehicle belonging to oscillator circuit tuned to same frequency as coupling circuit mounted on wheel rim
Inventor: FRITZE KURT
IPC: F16D66/02
Filed: 1976-11-23
Abstract: The transmission arrangement conveys the state of motor vehicle tyres, wheels and brakes without using wires. Two coupling coils are mounted on the relatively stationary part of the vehicle and near the wheel's inner side, and belong to an oscillator circuit. This circuit is tuned to the same frequency as the coupling oscillating circuit mounted pref. on the rim of the wheel, which can be switched on and off, or mistuned, depending on the state of the tyres and wheels. This frequency can in addition be wobbled. Thus, during each wheel revolution, the h.f. oscillation amplitude and/or frequency is briefly changed. This can be used to control an alarm system.

Title: BONDING METHOD USING RESILIENT HEAT RESISTANT LAMINATE - suitable for ceramics and refractory components subjected to meat cycling
Inventor: WIECZOREK LEONARD
IPC: F28F13/00
Filed: 1977-04-29
Abstract: Bonding ceramic or other refractory components which are subjected to thermal cycling and have different thermal expansions is described. The bonding of two components, at least one of which is ceramic, is achieved by a layer of resilient heat-resistant laminated composites consisting of layers of woven graphite cloth bonded together by silicone rubber layers. Components which have different thermal expansions or which are exposed to different temps. can be bonded together without fracture because of the resulting stress. An additional advantage is that the useful temp. of silicone rubber can be extended from 450 degrees F-600 degrees F.
