Title: Power drill coolant feed - has tube dipped into coolant reservoir when drill is inoperative for subsequent feed
Inventor: STIERLE WILHELM
IPC: G01F11/22
Filed: 1974-06-22
Abstract: Coolant to be fed to the bit of a drill is held in a tank partitioned into two sections, the smaller (5) of which communicates with the drip (or spray) feed (6) supplying the drill. The liquid in the reservoir (3) is in turn replenished from a large inverted flask whose neck dips into it. The object of the device is to transfer coolant from the larger to the smaller compartment of the tank at a measured rate, just while the drill bit is in contact with the workpiece. This is done with a tube (4) which has an opening at each end and is mounted as a lever. When the drill is raised, out of contact with the workpiece, the tube (4) dips into the reservoir and fills up.

Title: Brake pad retainer for disc brakes - retaining pins are held by clamping rings
Inventor: SCHULTE HERBERT DIPL ING
IPC: F16D65/095
Filed: 1974-06-26
Abstract: Retaining pins pass through the support plates of the brake pads, and are guided in bores of the brake saddle. The retaining pins (1) are held by clamping rings (7), which are pressed into a recess (5) in the brake saddle (4). The internal diameter of the rings engage with friction around the external diameter of the pins (1), at a point, the size of which prevent the pins from leaving their positions during driving. The rings consist of resilient plastics, and have radial slots (6), extending from their inner surfaces, and are pressed into the recesses. Each ring engages on a collar (8) on the recess, and is secured against falling out by a metal ring (9), which is a push fit.

The valve seat is fastened axially adjustable via distance rods (10) to a disc (1), which seals the aperture of a gas channel. The side of the disc away from the valve seat carries a housing (3), to which is fastened the unit (9) for producing the valve stroke.

Patent DE-2451136-A1 (DE)
Title: Stator winding arrangement for explosion proof motors - has slot contents designed to transfer thermal limitations from rotor
Inventor: ELENDER JOSEF DIPL ING
IPC: H02K11/25
Filed: 1974-10-28
Abstract: The application is to explosion-proof induction motors with main (2) and auxiliary (4) windings in the same slot as in 2434705, and meeting given thermal limits. For two and four pole wound rotor motors the thermal limitation with locked rotor is normally set by the rotor winding. By rearranging the stator configuration so that the part of the slot (1) nearest the air gap, and containing the main winding (2), has a smaller height to width (7/8) ratio than that part (3) holding the auxiliary winding (4), and by suitable choice of conductor cross sections, the limitation can be transferred to the stator without loss of performance. The normal winding temperature detectors can then be used to operate the protection.
Patent DE-2451962-A1 (DE)
Title: Analogue computing circuit for quarz oscillator - noise problems associated with small amplitude input by using comparator controlled stage
Inventor: ALLENSTEIN KLAUS
IPC: G06G7/16
Filed: 1974-10-29
Abstract: An analogue control circuit for the determination of the characteristic of a quartz oscillator performs either multiplication or division of two A.C. signals followed by multiplication or division by a constant. The solution provides a greater dynamic operational range, high computing speed and accuracy particularly in the situation where one input is of a very much smaller amplitude than the other. The larger amplitude input (A) is amplified (1) and the R.M.S. value generated by a rectifier (2) before the logarithmic function is generated (3). Signal (B) is transmitted through a similar arrangement except the rectifier (6) and a second amplifier are controlled by a comparator stage (8). The comparator ensures a constant gain factor through the second stage amplifier and rectifier and avoids any problem due to noise. The logarithmic output (9) is compared with Log A (10) to generate the required outputs (A/B.V, A.B.V.).

Title: Radioactive waste storage using ion exchange resin
Inventor: CUAZ DANIEL
IPC: G21F9/30
Filed: 1974-11-08
Abstract: The parent patent described a process for conditioning radioactive waste by incorporating the latter in powder form into a room temp. polymerisable resin and copolymerising the latter with a monomer to form a solid block. In the patent of addn. the radioactive waste comprises radioactive elements fixed into an ion exchange resin which has been used for purifying contaminated waters and/or radioactive elements incorporated into filtration and/or flocculation adjuvants (I). The process allows storage of ion exchange resin used, e.g. in purifying cell waters, and contg. radioactive elements, the radioactivity of the resin is also retained during storage. The ion exchange resin may be anionic (IRN 78, RTM) cationic (IRN 77, RTM) and it may be mixed with an equal amt. of a polymerisable resin e.g. an unsatd. polyester or an epoxy resin. (I) may be diatomaceous earth, cellulose or perlite. The polymerisable resin pref. contains a catalyst, e.g. MEK peroxide, and an accelerator, e.g. Co naphthenate.

Patent DE-2455741-A1 (DE)
Title: Articulated trailer with steered axle - uses independent suspension for twin wheels for added stability
Inventor: HILDEBRANDT WILLI
IPC: B62D13/02
Filed: 1974-11-25
Abstract: The articulated trailer has two or more rear axles with the front axle of each set arranged rigidly on the chassis. The other axles are linked to a steering control which follows the cornering of the vehicle and alters the setting of those axles using separately mounted axle supports. For added stability the rigid axle has each set of twin wheels separately mounted on elastic springs which enable those wheels to negotiate bumps etc., without placing all the load on one wheel. The trailer steering control can be used for short vehicles such as cement lorries etc.

Title: Forming strongly adhering metal coating on glass or ceramic - by applying intermediate layer contg. copper and its oxides, and heating
Inventor: STEINER INGO DR RER NAT
IPC: C03C17/06
Filed: 1975-07-26
Abstract: Intermediate layer is formed from copper and Cu2O and/or CuO. The copper oxide(s) is formed before, during or after the application of the intermediate layer. The assembly is heated to such a temp. that there is no formation of a liquid phase, and only diffusion or a chemical reaction takes place, e.g. Al2O3 and Cu2O giving 2 CuHO2. Since Cu can form mixed crystals with copper oxides, the whole intermediate layer strongly adheres to an oxidic substrate and also to any further metallic coating (pref. Cu) that can be applied galvanically (pref) or by electroless deposition (pref) or deposition from the vapour phase or cathodic sputtering. Method is useful in electronic, microwave technologies etc. Very firmly adhering metal coatings can be applied even onto very smooth and clean surfaces. Process is simple and inexpensive.

IPC: E04H4/12
Filed: 1975-11-11
Abstract: The swimming pool edge is esp. suitable or use with self-assembled pools lined with a layer of plastics sheeting. It incorporates an H-section overflow gutter, around at least part of the periphery, with one or more water outlets.
