Title: Cover plate fixing assembly for electric installations - has locking ridges in parallel elastic strips engaging recesses in installations
Inventor: STUMPF HEINRICH
IPC: H02G3/14
Filed: 1974-05-29
Abstract: The cover plate fixing assembly, for electrical installations, has a central locking ridge (3) formed around the inside of two parallel elastic strips (4) cutting diametrally across the cover plate (2). The ridges are semicircular and lie in semicircular cut-outs in the strips, and lock into corresponding recesses around the collar of the electrical installation.

Patent DE-2431813-A1 (DE)
Title: Diffusion inhibiting barrier layers - produced in semiconductor zones by nitrogen or oxygen ion implantation and heat treatment
Inventor: GRAUL JUERGEN DIPL ING DR
IPC: H01L21/74
Filed: 1974-07-02
Abstract: A diffusion-inhibiting layer in a semiconductor slab prevents a diffusion from an already doped zone during a heat treatment required in a subsequent process stage. Ions (N2) are implanted into the surface layer of the already doped zone and these enter into a chemical combination with the semiconductor material during heat treatment. This produces a diffusion-inhibiting layer for dopants. This is a simple way of producing integrated circuits with special qualities such as a reduced capacitance.

Title: Clip for securing container loads - with spring secured U-profile to clip into holes in track
IPC: B60P7/08
Filed: 1974-07-25
Abstract: The inside of the container, or even the inside of the lorry, is fitted out with reinforcement rails provided with arrays of rectangular holes. Special U-shaped clips (1) are looped at the ends of securing straps, with the free ends of the U clips bent outwards. This enables them to be clipped into pairs of square holes for snap fittings. One limb of each clip is fitted with a flat spring (9) which prevents the clip from dropping out of the holes. The system is simple to operate single handed and enables loads to be secured inside the containers.

Title: Wide-radius-curve high-speed railway junction points - have fixed-mounting tongues and movable elastically bending stock-rail sections
Inventor: KAIS ALFRED
IPC: E01B7/00
Filed: 1974-08-13
Abstract: The system is designed for use on railways carrying very high-speed traffic, where curves in junction points must be very gradual and on a wide radius, normally calling for long slender tongues which cannot easily be made sufficiently stab le, where a control mechanism moves tongues and stock-rails from a close-fitting to a diverging setting and vice-versa. Here the tongues (10, 11) are on fixed mountings and the stock-rails have movable sections (12, 13) in the vicinity of the tongues, which are made to bend outwards elasticity under the action of the control mechanism, so as to fit against the tongues or move away from them. The bending sections of the stock-rails may be connected by cross-struts.

Pref. for a constant pressure the temperature is gradually increased to a desired level and then decreased. Pref. the temperature gradient in the board is below 0.50 degrees C/S.
Patent DE-2445918-A1 (DE)
Title: Dough cutting and moulding machine - has dough thickness detector, and conveyor which stops when set thickness is exceeded
IPC: A21C3/10
Filed: 1974-09-26
Abstract: A dough cutting and moulding machine comprises a roll system and conveyor belts for feeding the dough; upstream of the entry roll there is a conveyor belt connected via a coupling to its drive; in the effective region of the entry roll there is a sensor which detects the thickness of the dough and, if this thickness exceeds a predetermined value, disconnects the coupling and thus stops the conveyor. In a preferred arrangement, there is also a lower limit switch; if the dough is too thin, actuation of this limit switch disconnects the doupling and also switches off the drive motor. The surfaces of the conveyor are pref. inclined towards one another. The roll system may be such that the dough s conveyed generally horizontally right as far as the cutting roll, or alternatively as shown. The sensing device may comprise a smoothing roll extending transversely right across the path of the dough, and pivoted about a support limited in its movement by upper and lower stops associated with the limit switches. In the continuous production of dough, if the mass becomes too thick the top becomes scraped, with consequent disruption to the later cutting process. Present arrangement prevents this happening.

Title: Slit plastics sheet for weaving into fabric - has edges curled inwards before reeling onto drum to prevent tangling
Inventor: HITE CORRIE ATKINS
IPC: D02H3/00
Filed: 1974-10-25
Abstract: A method of making reeled strips by longitudinally slitting plastic sheet and then winding the strps onto a long revolving drum, consists of rolling or folding the lateral edges of each strip to form it into a closed section, before the strip is wound onto the drum. Pref. the folding or rolling in is carried out as the strips are stretched, by passing them through slots or openings in a board extending across the width of the set of strips, the width of each slit being less than that of the strip passing through it. In particular, two successive boards each having slits in their edges may be used. Esp. for longitudinally slitting polyethylene or polypropylene sheet to form strips to be used instead of conventional fibres for making, e.g., by weaving or knitting packaging material bags, e.g. vegetable containers and the like.

Title: Volume control counteracting noisy surroundings - alters dynamic characteristics or volume in accordance with background noise level
Inventor: BECKSTEIN HELLMUT DIPL ING DR
IPC: H03G3/32
Filed: 1976-02-09
Abstract: The volume control, for making acoustic signals clearly audible in noisy environments, compresses the signal's dynamic characteristics and/or increases its volume depending on background noise. The background noise is measured by one or more transducers which then control circuitry altering the dynamic characteristics and/or volume. The degree to which compression and/or volume are affected by the background noise can be adjusted by a special control knob.
