Title: Thread wt determination - independently of thread speed on thread processing machines
Inventor: RAUH BERNHARD
IPC: D01H13/32
Filed: 1971-10-19
Abstract: Continuous weight determination of the amount of thread produced on thread-making machines and registering of the performance of thread-making and processing machines uses a screening mechanism at each of a number of working stations.

Title: Wedge shaped cooling and firing grates - having nozzles for air in staged vertical faces and ribs
Inventor: KAYATZ KARL-HEINZ
IPC: F23H17/00
Filed: 1973-11-22
Abstract: Grate for incineration of waste or cooling clinker is wedge shaped to allow mixing of material as it flows in direction 6 up the face of the grate from plate 1. The grate is formed as a series of steps on the vertical faces of which are air nozzles for combustion or cooling air. At regular intervals along the grate are ribs which run from the lip to the base. Further nozzles are present on the back of the lid. The grate is used for incinerator hearths and cement clinker coolers. In the wedge type grate, fires are often blown to the surface on simple inclined hearths and move rapidly over the rim without effective treatment. The stepwise construction without ribbing avoids this.
Patent DE-2358328-A1 (DE)
Title: Multi-purpose roller-blind-type wall-opening infill - with ribs on two or more opening-sealing tracks led in U-rails

There may be two cross-roller shafts at an interval corresponding to the length of a sheet; or more than two, close together, for one track each. The ribs on two tracks may be mutually offset. The front track may be transparent and waterproof.
Patent DE-2359428-A1 (DE)
Title: Continuous, automatic mfr. of prefabricated walls - by assembling and applying mortar to moulded blocks immediately after pressing
Inventor: GUNZELMANN RUDOLF
IPC: E04C2/04
Filed: 1973-11-29
Abstract: The device manufactures wall elements from snad lime- or concrete-blocks posesseing mating ends and cavities for mortar; the blocks are moulded in an automatic press and are ejected at press-stable height from where they are picked up by a clamp moving vertically and then horizontally to deposit the block on a prefabricated wall which is assembled on a trolley alongside the press. The clamp can be rotated 90 degrees on its vertical axis when required and the trolley can be moved along rails in steps, each step being the length of a block. After depositing each layer, a device feeding mortar travels over the blocks in accordance with a prescribed programme so both the cross-joints and the cavities are filled with mortar before the next layer of blocks is deposited on the wall. There is a substantial rend. in cost by making the blocks and walls at the same time.

Title: Optical scanning of rate of revolution of vehicle wheels - involves disc rotating synchronously with wheel
Inventor: LESTER WALDEMAR
IPC: G01P3/486
Filed: 1974-01-29
Abstract: Light is shone onto the toothed rim of the disc and the chopped light falls on a phototransistor which emits voltage pulses and no-voltage pulses alternatively via a resistor. The teeth or tooth gaps of the perforated or toothed disc are so shaped in a radial direction that they have a rectangular form whose width corresponds to the mean width between the lower and upper edges of the spaces/teeth or openings/tooth gaps. The lamp and the phototransistor are arranged in a holder which can be adjusted radially to the disc, in order to compensate the delay times of the phototransistor and to receive voltage pulses and no-voltage pulses of identical duration.
Patent DE-2407603-A1 (DE)
Title: Static mixer for belt conveyors - being trough shaped plough mounted to pick up material and then return it to belt
Inventor: MATUSZCZAK THEODOR
IPC: B01F13/00
Filed: 1974-02-16
Abstract: Static mixing device for mixing solids on a flat belt conveyor consists of a chute located on the belt with a leading edge on the belt surface followed by a converging section with walled edges. Material rises up the chute and flows over the edges. Distributor plates ensure that an even coverage of material leaves the mixer. The mixer can be formed like a ploughshare. The mixer has a wedge section and the material flows over the edges as with the wide front type. Several units can be placed side by side across the belt. They can be in a wedge shaped array with the tip of the wedge as a point into the material flow or with the wedge as a funnel into which the material flows. All the chutes need not be of the same but can be a combination of different types. For use where particulate material is being cooled, or dried during a conveying operation. Screw type conveyors do mix solids but tend to cause attrition with dust formation. Passage of air through the bed can also be used but without forming over the bed. Uniformity is not achieved. The device described overcomes these problems without resorting to complex mechanical devices.

Title: Terminal connector for HF coaxial cable - has captive collar in screw cap with ring strap engaging in internal slot
Inventor: GNUECHWITZ HELMUT
IPC: H01R9/05
Filed: 1974-03-02
Abstract: Terminal connector for high frequency coaxial cable with mechanical clamping. The joint is made to an instrument or armature by a captive tightening collar which engages with the screw cap. The cable is first stripped to the appropriate length while the inner conductor is made slightly pointed. It is then fed from the rear through a pair of sealing rings and the collar, till the outer conductor fits into the connector and the inner conductor into the bush. The screw cap is then tightened. The collar has a split and is cone shaped towards the two ends. The tightening of the cap will cause the collar to grip by an external ring strip seating in a slot on the inside of the socket.
