Title: Carbides with low free-carbon - with improved hardness characteristics
Inventor: MEYER HORST
IPC: C01B31/30
Filed: 1972-03-23
Abstract: Carbides and mixed carbides of Groups IVA, VA, VIA metals are made with a very low free-C content and considerably reduced O2-content, by treating the appropriate carbide(s) with at least the stoichiometric quantity of Sr, Ba or pref. Ca. The products are purer, harder and of lower particle size compared with the initial carbide, hence they are suitable for making hard alloys or for use in reactors and air/space flight technology. Either the temp. of the carbide/metal mixture is raised to above the m.pt. in the absence of air or treatment is carried out directly with metal vapour. The mass is then leached out and the product washed and dried.

Title: Ceramic drier - with alternating low press and hot air zones
Inventor: RIEGER WALTER
IPC: F26B5/04
Filed: 1972-07-28
Abstract: The drier for ceramic briquettes consists of a wire press, a brick cutter, a classifier and a set of two parallel tubular sections and a hot air drying section. The row of briquettes from the cutter go into the classifier contg. two conveyor bands for the rows of briquettes and then on to a tubular section movable perpendicular to the axis. When this section is filled with bricks, it is moved to a radially outward position and is subjected to evacuation. Simultaneously another parallel section moves into the central position to receive the bricks from the classifier and when that is full, moves outward for the evacuating position. The first tubular section returns to the central position and the evacuated bricks.

Title: Service interval alarm indication - is for lorries showing either a warning or an inspection request
Inventor: MASCHKE EDGAR
IPC: G07C5/00
Filed: 1973-07-11
Abstract: The mechanism arranges a counter to trip after a certain distance, measured in revolutions of the wheels, has been made. A reduction gear is arranged to turn a cam which has a non-central rotational axis, consequently each time the cam turns, it produces a count pulse as its tip passes the counter. Once the counter exceeds a predetermined valve an alarm is raised. The tachometer unit is driven by a flexible drive.
Patent DE-2347311-A1 (DE)
Title: Car safety belt quick release fastener - provides secure fixing but requires only small force to release belt
Inventor: STOFFEL ROBERT W
IPC: A44B11/25
Filed: 1973-09-20
Abstract: One half of the belt is attached to a socket and the other half attached to a metal tongue. When the tongue enters the socket, a slot at its end engages a blade-like projection of a pivoting catch which is rotated by the action of the tongue to a vertical position where the tip of the projection enters a slot in a locking member attached to the release button. The locking member normally prevents rotation of the pivoting catch so that it resists any tendency for the tongue to be pulled out of the socket. Pressure on the button lifts the locking member clear of the pivoting catch, permitting the belt to be released.

Title: System for controlling completeness of train - has ultrasonic transmitter on train and receivers on track
Inventor: HOYER GERD
IPC: B61L1/14
Filed: 1974-02-15
Abstract: The system is used to check the completeness of the composition of a travelling tain. The final wagon is provided with an ultrasonic transmitter which emits signals to receivers spaced along the track which in turn transmit the data to a central evaluation centre. The data can be transmitted as electrical signals for forming a report.

Title: Moulding coloured components of integral foam - in split mould with spacer plate restricting formation of flash
Inventor: HOYER EKKEHARDT
IPC: B29C44/14
Filed: 1974-02-16
Abstract: A coloured component of integral foam is produced in a split mould, the inner surfaces of which are coated with a lacquer of the required colour having a greater adhesive affinity for the foam that for the mould; the lacquer is dried, the mould is filled with resin and foamed and when the component is withdrawn, flash formed between the edges of the jointing surfaces of the mould is trimmed off. In the addn., the adjoining surfaces of the mould halves are also coated with the lacquer, and a spacer plate, limiting the extension of the flash, and machined possibly on its inner faces to give the impression of a sewn seam, is also lacquered before assembly into the mould. It is thus only necessary to trim off the overhanging edges of the lacquer coatings. Enables the full possibilities of the parent patent to be exploited. A non-fading colouring of the foam, much better than spraying and cheaper than laying on a plastic film. Ensures a neat finish, easy on the eye. A mould is shown with its upper and lower sections with coatings of lacquer extending over the edges which cannot be kep sharp, on to the jointing surfaces; assembled with the spacer plate. The inner face ensures a positive dimension for the flash and in the product, only the overhang of the lacquer layers needs to be trimmed off.

Title: Cellular brick made from concrete - has transverse and longitudinal ribs projecting beyond brick edge for keying purposes
Inventor: ROHRMOSER HEINZ
IPC: E01C9/00
Filed: 1974-03-12
Abstract: The cellular brick is formed from concrete and it has longitudinal and transverse ribs which cross each other and form rectangular cavities between them. The ends of the ribs project on all sides by half the cavity width beyond the bounding ribs. The edge projections of the longitudinal and transverse ribs have alternately a full depth and about sixty to eighty percent of full depth. The spaces between the projecting ends are slightly wider than the width of the projections. The ratio of the cavity width to the longitudinal and transverse ribs is slightly less tha ninety. These bricks are connected to form mats and are used for reinforcing embankments and especially for reinforcing bottoms of rapidly flowing steams. These bricks are readily joined by keying to form stiff reinforcing mats.

Title: Pressure release valve with external sealing disc - has sealing disc held over housing hole by adhesive for blowing out by excessive pressure
Inventor: KORNER RENZO L
IPC: H02B13/025
Filed: 1974-08-30
Abstract: The pressure release valve for e.g. a nuclear reactor encapsulation consists of a sealing disc which covers a hole in the equipment housing. The disc is glued to the outside of the housing by a permanently soft adhesive, applied around the outside of the hole. When the pressure inside the housing rises suddenly the disc is blown away from the hole, but is prevented from leaving the housing completely by angle brackets extending into the housing and fixed to the disc inside surface. The hooked ends of these brackets come up against the wall region around the hole when the disc has been blown clear of the hole. The internal brackets may be replaced by a cross-shaped bracket on the outside of the housing.

Title: Ink ribbon travel direction reversing unit - has each ribbon spool connected to its own electric motor fed by electronic unit
Inventor: DREHER KARL
IPC: B41J33/51
Filed: 1974-09-12
Abstract: One of the motors (M1, M2) winds the ink ribbon from the spool (S2, S1) of the other motor (M2, M1) to and fro its own spool (S1, S2). If, for example, the motor M2 is winding it consumes approximately 2.5 to 3mA. If the spool S1 is empty, the winding motor M2, as a result of the resistance of the ink ribbon F fixed at the end to the spool S1, draws up to 15 mA because of the locking action. By means of an electronic control system, which reacts to a five times increase in current, the voltage is so reversed that the motor M1 is current, with current and the ribbon is pulled in the reverse direction. This reversing mechanism avoids the noise and complexity of mechanical reversing mechanisms.
