Inventor: NEUMANN SALOMON
IPC: D21H17/25
Filed: 1969-06-04
Abstract: Paper, or similar fibrous sheet materials, can be sized with starch, or a starch-containing material such as flour, and/or hemicellulose, in an economic way by adding an aqs. solution or colloidal dispersion of starch and/or hemicellulose to a paper pulp, and effecting the precipitation of the starch and/or hemicellulose onto the fibres at a neutral or alkaline pH value in the presence of multivalent metal cations capable of forming with starch and/or hemicellulose a complex insoluble at this pH, preferably Ca++, Ba++, Mg++, Sr++, Zn++ or Al+++ cations, introduced in the form of hydroxides, chlorides, nitrates, sulphates or acetates. By this method, losses of the sizing material in water removed from the pulp are eliminated. The pH of the pulp can be adjusted to a neutral or alkaline value by addition of an alkali metal hydroxide or ammonia. The sizing material may be precipated together with a filler.

Title: Indicator for shotgun hits on targets moved on a frame - has an acoustic converter and counting system
IPC: F41J5/12
Filed: 1973-06-06
Abstract: The target for practice shooting is fixed on a moving frame and is actuated by a rope. The target moves against the background of a shot proof wall. Behind the back wall is a microphone connected to a counter assembly at the side of the back wall. The first counter of this assembly is triggered by the microphone when the shot hits the back wall. This counter adds the units or steps through which the target travels to its end point, and is coupled by a comparator switching unit to a second counter for measuring the target travel to the position in front of the wall where it was located when the shot hit the wall. The target can be moved by the actuating mechanism horizontally and vertically and similar counter arrangement is used for travel in this direction. A dye spraying arrangement is fitted above the back wall for covering the back wall with dye after recording the shot. This arrangement facilitates observation of the hit and its position relative to the target.
Patent DE-2333734-A1 (DE)
Title: Conveyor system for handling meat slices - matches supply-demand requirements by using photo-cell monitored double conveyor
Inventor: TOBY EDWARD PRICE
IPC: B65G47/30
Filed: 1973-07-03
Abstract: Two conveyors are used running concurrently with one another, in the form of multiple strips. The strips of the first conveyor are raised above those of the second up to a certain point after which they are lowered so that the strips of the second conveyor form the conveying surface. The point at which this happens can be moved along the conveyor. If meat slices from a cutter are deposited at irregular intervals onto the first conveyor, they can be monitored as they transfer to the second conveyor, by a photo-cell, such that if one slice has transferred and a certain required interval required between items has passed without the arrival of a succeeding slice, the junction of the conveyors can be moved in the direction of motion and at the speed of the second conveyor until a succeeding slice does arrive. Thus a consistent interval can be maintained between slices the reverse operation taking place is a slice arrives too rapidly. Further photo-cells can be used to monitor whether the succeeding process machine is ready to receive the next slice and the preceding machine has produced one, providing complete process control.

Title: Declutching mechanism for vehicles - incorporating a self-centering device for the rotating thrust ring
IPC: F16D23/14
Filed: 1973-09-28
Abstract: To construct a clutch withdrawal mechanism in which the non-rotating withdrawal sleeve is concentric with the operating levers on the rotating clutch is in practice not possible. A solution is to allow the rotating part of the thrust ball-race to be self-centering relative to the non-rotating sleeve. The sleeve, flange and operating fork form the non-rotating withdrawal sleeve. The inner race of the ball bearing is formed from plate material, at least two but preferably three spring tongues being shaped integrally with it. This is held between a spring ring and a rubbing ring. The solid outer race presses against the clutch operating levers. On the first operation of the withdrawal sleeve, the ball race will centralise itself with the rotating clutch operating levers and will remain centralised.

Title: Piston ring for large two stroke diesel - ring ends trapped against piston by radially spring loaded insert
Inventor: STINNER OTTO
IPC: F02B3/06
Filed: 1973-11-09
Abstract: The two ends of a piston ring foru use in a ships engine are scarfed at an angle which allows them to be held against the piston by a trapezoidal insert. The insert has a curved outer surface which corresponds to the curvature of the cylinder bore and includes a radially disposed set screw which is secured to an arcuate U section retaining plate disposed against the radially inner side of the piston ring. The set screw traps a coil spring between itself and the insert which allows the insert to resiliently force the ring ends against the retaining plate. Projections on the inclined faces of the insert locate in corresponding grooves in the ring ends. The construction avoids deformations in the ring due to thermal expansion.

Title: Endless belt centering mechanism - has slewing roller round which belt runs at small angle
Inventor: FRITSCH RUDOLF PAUL
IPC: B65H23/02
Filed: 1974-02-19
Abstract: The mechanism is for centering a belt or web running over a number of rollers, one of which is so positioned that in passing over it the belt encloses a small angle. This roller slews about an axis roughly at right angles to its own and bisecting the angle enclosed by the belt. The roller can also be adjustable in the direction of its slewing axis. Thus the roller can be used for tensioning the belt as well as centering it. The mechanism is entirely automatic in action, needing no detector or adjusting devices, and any deviation of the belt causes it to slew until the slewing axis passes through the belt centre line again.
