Patent DE-2426076-A1 (DE)
Title: Casting mould for automatic casting machine - pressed by tie rods to supporting block with thrust faces
Inventor: STAMP THOMAS BLACKLEDGE
IPC: B22D25/04
Filed: 1974-05-30
Abstract: The casting mould, for use in automatic casting machines for thin plates (lead grid plates for accumulators), consists of two halves, one stationary and one movable, which are pressed against each other by tie rods between supporting blocks. The tie rods are arranged near the filler spout and act on thrust faces on opposite sides from the tie rods, near the two upper corners, and near the bottom. This prevents thermal distortion and consequent flash formation on the castings. It is a simple way of producing this casting of complicated shape.

Title: Rhenium extn. from dilute acid solns. - copper and iron powder addn. increases rhenium yield in the ppte.
Inventor: WRIGHT CRAIG NELLIS
IPC: C22B3/24
Filed: 1974-06-21
Abstract: The process consists of adding particles of a metal which sufficiently electropositive to ppte. all the Re from the soln. followed by sepn. of the ppte. and recovery of the Re. Either a soluble sulphide, or particles of a collector-metal which is more electro-negative than Re, are pref. present during the reaction. The presence of a sulphide or a collector metal give very high yield even from dil. solns. contg. only 0.000033 g/l Re. The copper can be either in the soln. or present as powder. The process is esp. applicable to the winning of Re at copper mines where the acid-leaching of wastes results in solns. contg. e.g. 0.00001 g Re and 1 g Cu per litre. Copper and iron powders can be used or a soluble sulphide, Na2S or H2S with iron or zinc.
Patent DE-2436997-A1 (DE)
Title: Sewing thread material - is composed of synthetic filament core cladded with staple fibre material to withstand friction heat of high-speed needles
IPC: D02G3/36
Filed: 1974-08-01
Abstract: Sewing thread in the form of a core yarn, where the core is of continuous, stretched and fixed synthetic spun material and the cladding uses fibres of vegetable or semi- or full-synthetic origin. The cladding is twisted at the same rate as the core so that it is fully cladded. Two or more of these cored threads, which have been twisted in opposite directions, are twisted together so that the end product is free of loops. The process allows a two-component thread to be formed from a mixture of continuous filament and staple fibres to increase the range of effects, withstanding friction heat up to 400 degrees C at the needles of high-speed sewing machines.

Title: Rolling head to profile cylindrical work pieces - uses hydraulically or pneumatically driven actuator
Inventor: ABELE JUERGEN
IPC: B21H3/04
Filed: 1974-08-13
Abstract: The rolling head has two rollers, which are retained in pivoted arms, and, during the rolling procedure, may be moved towards each other, up to a final measurement, radial to the workpiece. The head has a hydraulically or pneumatically driven actuator (40, 42), acting onto the free ends (41) of the pivoted arms. The actuator contains a hydraulic piston (38) to operate an expanding wedge (40), and a hydraulic cylinder (17), which may be screwed into the rolling head frame (16). The piston has a stop, acting with an additional surface on the cylinder, so that the closing movement of the rollers is limited by the screw-in adjustment of the cylinder, corresponding to the desired and diameter of the profile.

Title: Self-adjusting device for drum brake - takes up lining wear with spring loaded lever and ratchet wheel
Inventor: NEWSTEAD CHARLES
IPC: F16D65/09
Filed: 1974-08-30
Abstract: The device (11) is used with a two leading shoe drum brake. The housing of the device (11) is fixed to the brake backplate so that the web of one brake shoe fits in the slot in the rod (22) and transmits a force, through internal members which are screwed together, to the rod (12) which abuts against the other brake shoe. As the brake linings wear, the ratchet wheel (30) is pushed towards the right and pushes the bar (34) in the same direction. The bar (34) has a projection which engages the lever (31) and moves the end (35) over one of the ratchet teeth. When the brake is relased the ratchet (30) rotates to take up the wear.

Title: Spring loaded folding tow bar - with links braced by outer sleeve to form rigid rod
Inventor: BASTUBBE KARL-HEINZ
IPC: B60D1/155
Filed: 1974-10-25
Abstract: The tow bar is made in two or more sections which are linked by coupling pieces (4) to form chain type links between the tow bar sections (1). This enables the tow bar to be folded into a manageable length to be stowed in a car boot. The outside of the tow bar is fitted with a sliding sleeve (6) which is spring loaded to push the sleeve over the link section to form a rigid structure. The extent of the sleeve movement is limited by a stop (9) on the tow bar. To fold the two bar the sleeves are pushed back and the links folded. To erect the bar the ends are pulled apart and the sleeves move into place automatically.

Title: Counter stroke forge with equal weight hammers - has hydraulic and pneumatic actuation system for ensuring high blow energy
Inventor: BECHE HANS DIPL ING
IPC: B21J7/34
Filed: 1974-11-29
Abstract: The counter stroke forge with coupled hammers of equal weight, in which the damaging effects of hard blows due to small deformations in the finishing stage of workpiece are avoided. The lower hammer is lowered hydraulically and hydraulic coupling is used for lifting the upper hammer. A piston compresses a gas bolster with a pressure which subsequently produces impact energy for the blow. The die forged workpieces are produced in one blow due to the higher energy. The piston generating the pressurised gas bolster is connected with the upper hammer by a spherical joint whose centre is at the centre of gravity of the upper hammer. An infrared controlled instrument prevents a full blow if no hot workpiece blank has been placed between the hammers.

Title: Shaft furnace for roasting lumps of lime, dolomite etc. - using baffles to sort lumps when they enter the shaft
Inventor: BECKENBACH KARL DIPL ING
IPC: F27B1/20
Filed: 1975-09-20
Abstract: Process for calcining and roasting lump materials,e.g. lime, dolomite, magnesite, cement, etc. in a shaft furnace heated by gas or oil, where the charge travels down through a preheating zone to a calcining zone, contg. burners in the side walls round the longitudinal axis of the shaft, and followed by a cooling zone; the larger lumps pref. travel down a central column whereas the smaller lumps travel downwards near the wall. The novelty is that the charge is not previously sorted but slides down a slope for automatically sepg. the lumps according to their size on entering the furnace, and a channel is formed on the furnace axis down which the larger lumps travel. No prior sorting of the charge is required and there is optimum use of the combustion gasses and the cooling air.

Patent DE-2613874-A1 (DE)
Title: Interference monitor for radio communications link - reduces carrier interference by shutting down transmitter in absence of modulation
Inventor: CHRISTIANSEN HANS-MARTIN DIPL
IPC: H04B17/18
Filed: 1976-03-31
Abstract: The interference monitor, for a radio communications link, monitors the interference caused by other transmitters operating at adjacent frequencies. Such interference is reduced by increasing the degree of modulation of the carrier. A carrier without modulation causes the greatest interference. The monitor therefore measures the degree to which a carrier is modulated. Part of the signal is bled off after the transmitter modulator and passed to a local demodulator (HD). The demodulator's output operates a switch (SE) that reduces carrier power or prevents the carrier being transmitted at all. The monitor is especially applicable to PCM systems where PSK modulation of an RF carrier is employed.
