Title: Injection around metal part - using sealing cone
Inventor: RHEINLAENDER HELMUT
IPC: B29C45/14
Filed: 1973-07-20
Abstract: A method of injecting a plastics surround onto a metal component, e.g. for a suspender clip, uses a number of moulds uniformly spaced on a turntable, each offered in turn to an injecting head. The apex of the sealing cone of the injection head continues as a cylindrical portion, which plugs the nozzle opening, pressurises the material in the nozzle, and ejects the moulding from the mould.

Title: Composite electrodes of lead dioxide on titanium substrates - using intermediate layer of titanium or tantalum carbide
Inventor: HABERMANN WOLFGANG
IPC: C25B11/10
Filed: 1973-09-05
Abstract: The electrodes are made by the anodic deposition of PbO2 on Ti substrates, where the Ti is first provided with an intermediate layer of a carbide or boride of elements in sub-gps. 4 and 5. The layer is pref. applied by plasma-spraying. Suitable carbides and borides are those of Ti and Ta, esp. titanium carbide, tantalum carbide and tantalum boride. The electrodes made by this process are suitable for high current densities without the danger of the PbO2 falling off due to polarisation and the formation of TiO2.

Title: High-efficiency warm air hand drying machine - has upwardly facing basin preventing premature escape of warm air
Inventor: BURGIN GERARD
IPC: A47K10/48
Filed: 1973-12-05
Abstract: The air outlet opening leading from the heater is in communication with an upwardly facing basin so that the warm air is directed into this basin where it is trapped allowing the damp hands to be thoroughly and forcefully enveloped by the warm air, thus speeding up the drying process. The basin is preferably moulded on to the housing containing the hot air blower and the hot air is likely to be trapped longer if the rear wall of the basin is higher than the front wall and if the oval basin opening is narrower than the diameter of the middle of the basin. Several air outlet openings from the heater can be provided to ensure a more concentrated air circulation.

Title: Machine for stacking bricks for transfer to kiln - has continuous conveyors forming rows of bricks on grouping table
Inventor: KAMPHUES HERMANN
IPC: F27D3/00
Filed: 1975-02-20
Abstract: The machine for building up of stacks of brick blanks forms, at first, compact courses of dried blanks which are subsequently stacked for transport into the firing furnace. The blanks form a compact layer of longitudinal and transverse rows, and the layer is subsequently into a stacking layer. The compact blank layer has a smaller number of transverse layers than the compact layer. The remaining transverse rows are temporarily stored and supplied to new compact layers for forming extended compact blanks layers from which further stacking layers are formed. The compact blank layers are forked by an arbitrary number of supply conveyors and a conveyor is not stopped on forming longitudinal rows.

Title: Gear wheel coupling with synchronization lock - has slider blocks to override lock at high speed due to centrifugal force
Inventor: MAGG ALFRED
IPC: F16D23/02
Filed: 1975-03-07
Abstract: A coupling assembly of a vehicle transmission is used to link two independently revolving gear wheels with the common gear shaft. The outer coupling sleeve which is axially movable has an external groove for the location of the switch lever fork. Each gear wheel is provided with a lock ring which are placed axially side by side inside the coupling sleeve. Three equally spaced slider blocks placed between the lock ring pair ensure that at low speeds coupling engagement is only possible when the two gear wheels have synchronized rotation. At high speed centrifugal force disengages slider blocks since synchronization is obtainable by altering the engine speed.

Title: Contact element for edge of printed circuit board - avoids damage to board by using inverted double contact T below upper arm of C-piece
Inventor: MOUISSIE BOB
IPC: H01R13/115
Filed: 1975-04-21
Abstract: The contact element for the edge of a printed circuit board, consists of a C-shaped end whose arms engage over the edge of the printed circuit board and two contact pins at right angles to one another and projecting from the spine of the C. The top arm (2) of the C forks downwards into two branches giving an inverted T structure (4). The lower surfaces of the T's crosspieces make two contact regions (5, 6) that touch two corresponding contacts on the printed circuit board. Each contact element therefore connects with two contacts. The structure and material are such that there is no danger of damage to the board because the contact force is relatively small.

Title: Jet loom jet unit - having a common angled tube for main and fluid channels to prevent turbulence
Inventor: FRICK ERNST
IPC: D03D47/38
Filed: 1975-05-05
Abstract: Appts. carries a weft yarn in a fluid stream, in a jet loom, with the jet main channel and the fluid channel formed as a common angled tube, where one arm is used for each channel to join each other at an obtuse angle, while the yarn channel is an extension of the main channel. The use of a single tube ensures that there is not turbulence in the jet unit which would diminish the power of the fluid stream, allowing longer weft lengths to be carried across the loom, also allowing a number of jets to be assembled in a confined space for multi-weft insertions.
