Title: Dot coding system for the blind - based on ternary code to facilitate conversion into alpha:numeric characters in machine system
Inventor: CORZILIUS AUGUST
IPC: G09B21/02
Filed: 1975-09-08
Abstract: A dot coding system for the blind is based on a ternary weighted code to permit ease of machine conversion to alpha-numeric character s. A three digit ternary code provides the necessary capacity for representation of alpha beta characters using the symbols 0, 1, 2. The dot code equivalent is represented by a square field with the top row indicating the 1's, the middle row the 2's and the bottom the 0's. For reading, the square field is considered as being composed of three column regions, thus indicating the order of dots. Numbers 0-9 are represented by a single dot. For the numbers 1, 2, 3, the dot occupies top, middle and bottom positions in the first column position. For the other two groups (4, 5, 6 and 7, 8, 9) the column position is moved. A double dot signifies the '0' digit.

Title: Hydraulic support cylinder for loading bridge - is operated and controlled by gear pump and manually operated valve
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1975-10-11
Abstract: A loading bridge has a vertical support leg which consists of a hydraulic cylinder assembly. A hydraulic pump (11), driven by an electric motor (12) supplies the hydraulic pressure to the cylinder through a valve (9). To outstroke the cylinder, the motor switch (14) is closed so that the gear pump (11) produces the required pressure. The oil flows past the nonreturn valve (9) and outstrokes the piston, thus lifting the loading bridge. In order to lower the bridge (1), the motor is switched off and a by-pass (19) inside valve (9) is manually opened. The weight of the bridge (1) forces the oil through the gear pump and back into the oil sump (15).

Title: Rotating carpet shampoo brush producing dry foam - uses bearing action of foam liquid inside brush
Inventor: OTTAHAL RUDOLF DIPL ING
IPC: A46B13/04
Filed: 1975-10-22
Abstract: Rotating disc-shaped brush of the carpet shampoo machine is made up of a rotating part (10) and a fixed part (11) which is mounted inside the machine to form a trough-like housing for the foam liquid and the generation of dry foam. The dry foam emerges through the openings (27) and slides along the inside of the wall (15) to the carpet. This dry foam is produced during operation by the beating of the foam liquid between the circulating ribs (17) and the fixed bristles (26) of the brush, these radially attached upright ribs (17) are normally mounted on the rotating part of the brush. Since only dry foam is produced there is no danger of too much liquid overwetting the carpet, especially as the foam itself is produced inside the brush without the aid of any other external components.

Title: Sliding clasp fastener in halves with buckle - has fittings accurately aligning clasp for buckling and unbuckling
IPC: A44B19/38
Filed: 1976-06-23
Abstract: A sliding clasp fastener, of the type which can be separated into its two halves, has a buckle comprising a tongued-and-grooved section which lock into each other. The two sections of the buckle interlock on a surface at right angles to the plane of the fastener. A clasp with a "Y"-shaped plan and suitably curved flanges fits over the two sections of the buckle, which each have a concave surface corresponding to the curvature of the flanges. Close to the grooves section of the buckle there is a boss provided on the carrier attachment which holds the clasp in its bottom position. This boss also acts as a guide when the clasp is assembled on to the buckle section with the groove, at the bottom end of which there is a stop allowing the clasp to be pushed on but preventing its being slipped off. The two sections of the buckle are produced from synthetic material by injection moulding. In known sepg. fasteners, the plug and socket details have straight backs so that the clasp is not positioned properly for the insertion of the other detail of the coupling, whilst the basic assembly is also complicated and cannot be effected automatically. The present fastener overcomes these difficulties. The clasp is positioned accurately for easy joining and separating.
