Title: Method of preparing scrap vehicles for transport - compression of bodies to minimise volume en route to scrapping
Inventor: HENSEN GUENTHER
IPC: B30B9/32
Filed: 1973-09-15
Abstract: The bodies are compressed quickly into a mass of small volume and thus increasing the payload of the transporter vehicle and reducing its turn around time and the time taken at the scrap yard. The equipment includes a semi-trailer. On the towing vehicle is mounted a long jibbed, swivelling crane with a grab. The trailer platform is inclined towards its rear at the end of which is a rack.

Title: Transporter for underground quarries or mines - has extending skip with movable wall as self loader behind single axle vehicle
Inventor: GALIS ALEX J
IPC: B60P9/00
Filed: 1973-12-17
Abstract: The transporter comprises a low profile vehicle with a single axle front end on which the drive unit and driving position are located. This is hinged to a two axled trailer by hydraulic hinges for steering. The trailer has a front section with a movable front wall to press the loaded material towards the rear section. The rear section can be extended hydraulically to take more load. This enables the vehicle to be loaded by positioning it under the end of a conveyor belt, while the loading capacity is increased by not having an integral conveyor floor. The rear of the trailer can be dropped to the floor to act as a scraper, in which case the material is gathered and pressed forwards to fill the load space.

Title: Concrete channel or tunnel inner encasing - mobile structure for concreting base sides and roof in one operation
Inventor: DOMESLE BENNO
IPC: F16L1/038
Filed: 1974-06-05
Abstract: Shuttering for a concrete channel where a truck carries the complete shuttering and travels along the length of the channel. The supports for the frontal truck travel on a set of wheels on the prepared base 2, while the supports for the rear truck travel on their set of wheels on the already concreted bottom 1. The side walls are radially moveable. Supports have height adjusting spindles. Another type of construction has all wheels on the concreted base and the encasement suspended from a strong cantilever in front of the track.

The difference in stroke (19) does not exceed the loading surface of the non-raisable track.
Patent DE-2429510-A1 (DE)
Title: Bypass valve for hydraulic oil filter - being piston valve which opens recycle when pressure drop exceeds set valve
IPC: B01D35/147
Filed: 1974-06-20
Abstract: Bypass valve for hydraulic oil filter is located on a recycle line and opens when the pressure drop across the filter exceeds a preset valve. The pressure drop itself is used to actuate the valve, this being a piston type slide valve with one control port connected to the filter inlet and the other to the filter outlet. The valve is held in the closed posn. by a spring, the tension of which corresponds to the max. allowable pressure drop, which is adjustable. A relief valve is mounted on the control line between the filter outlet and the recycle line and a restrictor is placed in the control line from the outlet to the by-pass. An indication or shut down switch can be coupled to the bypass, of particular application to hydraulic systems. By-pass valve serves to protect both the filter from excess pressure and hydraulic valves from dirty oil. Some bypass valves merely by-pass oil around the filter and allow dirty oil to proceed into the hydraulic system. This is unsatisfactory and the valve described avoids this.

Title: Cutting apparatus using circular knives - cuts squares or cubes out of soft or frozen material using friction drive
Inventor: BAUER KONRAD PROF DR ING
IPC: B26D3/06
Filed: 1974-06-21
Abstract: The drive to produce a straight movement is applied between the material to be cut and the cutter carrier while the rotating knife movement is provided either by friction between the cutter (1) and material or a friction wheel (2) in contact with a driving wheel. Material may move against the knife or the knife may move against the material; backward and forward cuts are possible. For cutting of blocks, squares or cubes several knives may be mounted on one carrier at right angles to each other when the preferred position of the knives to the block should be 45 deg. or parallel. Where a mechanical friction drive is used only one of the knives is driven by it, the other one being driven by the shaft of the knife. The size of shapes to be cut is adjustable.

Patent DE-2436314-A1 (DE)
Title: Protection circuit for class-B output stage amplifier - has electronic fuse controlled by rectified and compensated output from stage
Inventor: KARBOWSKI GEORG DIPL ING
IPC: H03F1/52
Filed: 1974-07-27
Abstract: The protection circuit, for a class-B output stage amplifier, has an electronic 'fuse' whose response curve (frequency against output stage collector current) is controlled by a voltage derived by rectifying the output of the output stage. The output voltage is passed via a frequency-dependent voltage divider (18-21) to the rectifier (5). Before passing to the 'fuse' the rectifier output is connected to an earthed capacitor (2) that compensates for phase shifts between the a.c. output voltage and the a.c. collector current over the amplifier frequency band. The capacitor is chosen small so that compensation only occurs in the upper part of the band and thereby reduces the 'fuse' response time.

Title: Amplitude modulated AC voltage demodulation method - used when difference between carrier and modulation frequencies is small involves low inertia switch
Inventor: THELEN PAUL
IPC: H03D1/22
Filed: 1974-12-19
Abstract: A low inertia switch (S) is connected only briefly in the voltage maximum zone, so as to apply periodic voltage pulses in the rhythm of the alternating voltage of the carrier to a smoothing capacitor (C). These voltage pulses correspond to the maximum valves or peaks of the carrier voltage, and the demodulated voltage is collected from the smoothing capacitor as a modulated direct voltage. The switch (S) has three connections (Do, Di, Ci). The first connection Do is the output and is connected to an amplifier (A2) and the smoothing capacitor in parallel, and the remaining two connections are inputs.
