Title: Rounding sharp edges of bricks before firing - by applying oblique rollers to the extruded clay, before, during or after cutting
Inventor: ROEBEN WILHELM
IPC: B28B11/08
Filed: 1975-07-25
Abstract: The method may be applied to produce bricks with definitely-rounded edges, but is thought of also as merely taking away the excessive sharpness of a too-square corner. Thus the rollers may be almost V-shaped or, as in the illustration, rather more rounded. Bricks may be treated singly or grouped into blocks: the blocks may or may not be already cut. In the illustration a number of rollers (15) driven from a common axle (13) are combined with knife blades (14): these blades may perform the actual cutting or may move withint cuts already made. The spaces between the rollers which shape the corners, can accommodate profile rollers to apply a surface finish to the face of the bricks.

Title: Car seat belt tensioner - has single friction charges acting in sequence to raise belt force steadily in sudden stopping
Inventor: HOFFMANN GUENTER
IPC: B60R22/195
Filed: 1975-09-13
Abstract: The car set belt tensioner consists of a tensioner piston engaging the belt from inside a cylinder in a response to a propellant ignited by a sensor. The propulsion is supplied by a number of single friction charges (11, 12) which act in sequence to produce a steady increase in belt force in the event of the vehicle suddenly stopping or pulling up short. Preferably there should be two charges which ignite at an interval. It is also possible to use two charges which, though ignited at the same time, operate at a timed interval. If this is done, the first charge should be powder and the second charge operating later should be a powder charge which produces a propelling gas.

Title: Control system for model electric railway - has pulsed DC which controls speed and direction of trains drawn by three different locomotives
Inventor: INGBERT BASTIAN DIPL ING
IPC: A63H19/24
Filed: 1976-01-20
Abstract: The model railway consists of loops of interconnected tracks (S) with three locomotives (L1,L2,L3) running on different parts of the track simultaneously. Mains current is supplied to the control box (St) which transforms the a.c into a pulsed d.c of 0.5 milli-second duration. These 0.5 milli-second pulses can be combined to give pulses of different durations up to 4 milli-seconds. Two players (A) and (B) can operate the controls (R1,R2) and (R3,R4) respectively to control different sections of the track. Each of the locomotives (L1,L2,L3) respond only to a particular pulse frequency. This frequency depends on which of the switches (S1 to S8) is operated and in this way each locomotive can be separately controlled.
