Title: Ultrasonic pulse method for product testing - radiation is directed on tested object at angle
Inventor: SCHRAIBER DAWID SOLOMONOWICH
IPC: G01N29/28
Filed: 1973-08-21
Abstract: The object is immersed into a transmission medium, and reflected pulses, containing information on the presence of a defect, are received. The radiation is applied to the object in the form of a convergent beam, focussed after reflection on the reception plane; rays reflected from the object surface and from a defect are separate in space; radiation reflected from the object surface is screened off; the ultrasonic oscillations are radiated by the concave side of a spherical surface. The method increases the possibility of accurate measurement and the "dead" zone is reduced down to 2mm.

Title: Impact type of pipe connector - allows play between pipe ends using sealing rings and connector with muff coupling
Inventor: GIERSE BENNO
IPC: F16L19/02
Filed: 1973-12-15
Abstract: The connection can be used for a wide range of temperatures and can accept wide temperature fluctuations. Unlike normal designs there is no direct metal to metal contact but radial sealing rings are used allowing play between the pipe ends. There is a union with impact shoulder that moves on the end of each pipe. The shoulder has an inner flange and the muff coupling forces a first radial sealing ring against it. In the overlap zone between the muff coupling and the union, a second seal is inserted. This fits in a circular groove in the union or the muff coupling. An impact ring holds the shoulders together and is secured by shear bolts.
Patent DE-2364208-A1 (DE)
Title: Twin-wire papermaking appts. - with stock inlet passageway having straight and parallel walls
Inventor: WARD GEORGE T
IPC: D21F9/02
Filed: 1973-12-22
Abstract: The inlet to the papermaking machine consists of a relatively long passageway formed from approx. parallel impervious walls. The stock flow is accelerated in this passageway until equilibrium conditions are established and the entire flow of the suspension is moving uniformly in the same direction at the same speed. A pair of forming carrier wires enter the inlet section, and run along the terminal sections of the walls of the passageway. They capture the flowing stock, without any web formation, and transport it to the forming section where water is removed from the suspension to form a paper web. By controlling the uniformity of the stock flow a better quality paper is produced.

Title: Hydraulic accumulator charging valve - contains spring-loaded control slide and connected switching slide
Inventor: STAISCH DIETHER
IPC: F15B1/027
Filed: 1974-05-24
Abstract: The system is particularly for use with plastic sacks, and as a first lot of sacks arrive one after the other their left-hand sides are folded over on top of the right-hand ones by guides and folder plates. They are then deposited in a stack until the desired number has been assembled, whereupon guides and plates are reset to fold the ensuing ones over in the opposite direction and deposit them on a further stack. While this is taking place the completed first stack is conveyed away. The conveyor can discharge into a shaft with a removable interemdiate stack support in it and can incorporate suction belts in the centre of which are two spiral mirror-image folder plates directing the sacks towards opposite sides of the conveyor. The vacuum to the two sets of belts is separately controlled.

Title: Additional braking device for eccentric presses - in which eccentric shaft is braked after each revolution has contact bar and disc
Inventor: JUNGINGER GEORG
IPC: B30B15/10
Filed: 1974-11-07
Abstract: The press is driven by a rotating shaft with an eccentric and the shaft with the eccentric abruptly stops when the brake machinery fails because the rotating contact bar (9), which is arranged for displacement on a relative contact disc during longitudinal displacement, acts upon an energy suppressing element which dissipates heat produced by friction. The bar (9) has a recess which can permit the through-passage of contact disc and it has a set of teeth which engage with the rack (17) of an operating lever (18). In normal operation the eccentric shaft is stopped at the end of each revolution with the press raised.
