Title: Serrated metal ski attachment - is used to remove packed snow from ski boot soles
Inventor: OBENAUS ERWIN
IPC: A63C5/06
Filed: 1975-04-19
Abstract: The ski has an attachment added for removing packed snow or ice from the soles of ski boots to ensure simple entry of the boot into the harness. The attachment consists of a metal U shaped profile (1) which is fixed by screws to the upper surface of the ski (2) so that the unturned flanges of the profile run either across the width or down the edges of the ski so that while the ski is held by one foot in the harness the sole of the other boot is drawn across the front flange to remove the packed snow. This shorter front flange can also be given a toothed edge to assist in the removal of ice from the boot sole. In alternative forms the attachments can be in the form of a T profile or a simple angle iron screwed to the ski either of which can be provided with a toothed edge.

Title: Conveyor for horizontal transport of rollable workpieces - ensures alignment of workpieces between processing machines
Inventor: VORTMANN WALTER
IPC: B65G47/26
Filed: 1975-05-02
Abstract: The conveyor ensures that the cylindrical workpieces such as shafts, which are transported between processing machines, are properly aligned. The conveyor has a sequence of support arms (3) for the workpiece. These arms extend in the direction of movement and swivel about horizontal axes (1) some distance from their centres of gravity. The top of each arm has a flattened recess (11) for the workpiece (10) while its lower surface has two fixed stops (5, 6). A shaft (8) located below the support arms has cams (9) which act cyclically on the support arms and move them from one position (6) in which a workpiece rests in a recess to a second position in which the workpiece rolls from the rest position in the direction of transport into a third position determined by the other stop (5) or rolls back into the first position.

Title: Elastic securing bolt for windscreen - having rivet shaped stud with spreading end to secure glass
Inventor: BUCHHOLZ PETER
IPC: B60J1/00
Filed: 1975-06-27
Abstract: The glass pane (3) of the vehicle is provied with fitting holes aligned with similar holes in the window frame (1). A special elastic covered stud (2) is fitted through the two holes, from the inside of the vehicle. The glass rests on a flange (5) of the elastic cover to cushion it on the window frame.

Patent DE-2628101-A1 (DE)
Inventor: MISZAK PAWEL DIPL ING
IPC: F22B35/10
Filed: 1976-06-23
Abstract: Between economiser (4) and evaporator (6), a spraying line (25), which has a valve (30) and opens into the pipe system of the steam generator at a spraying point (12) between two superheaters (10, 13), branches off. A control unit (73), which responds to a temperature-dependent actual-value signal, from the region of incipient superheating, and a load-dependent desired-value signal, influences the quantity of water supplied to the evaporator (6), by adjusting the valve (30) in the spraying line (25).

Title: Intermediate tube plate formed on tubes with expanded ends - by slow-setting adhesive beadings around tubes which merge on contact
Inventor: RICHTER DIETRICH
IPC: F28F21/06
Filed: 1977-03-11
Abstract: Mfr. >=1 intermediate tube plate between the top and bottom tube plates of a heat exchanger is used where these main top and bottom tube plates are formed by connecting together the expanded and flattened (typically hexagonal) ends of the tubes. For each intermediate tube plate, an annular beading of an air-setting plastics or adhesive material is formed around each tube at the appropriate height. When all the tubes are packed together to form the exchanger assembly, these beadings come into contact and combine to form a continuous tube plate which then sets. The material used is a non-drip adhesive or plastics, esp. very slow-setting. By forming a beading of plastics material, intermediate tube plates can readily be produced at the desired position.

Title: Precious stones optical support - has tube with bevelled surface on which stone rests for examination by transmitted light
Inventor: HEIBERG AXEL LEOPOLD
IPC: G02B27/00
Filed: 1977-04-05
Abstract: A support is used for the examination of cut diamonds or other precious stones, pref. by illuminating them in the transmission mode. It has a bevelled surface (40) in a metallic tube (31) for a tube made from some other material impermable to light whose cross section and the circumference of the precious stone under examination are similar. The internal dimension of the tube is slightly less than that of the precious stone and the tube is fitted with a grooved collar (38). The support is able to be rotated through 360 or more and can be inclined, in some cases, up to 45, thus making it possible to examine the precious stone under every angle of interest.
Patent DE-2715869-A1 (DE)
Title: Tennis racquet with double stringing - has spacing between strings increasing progressively from centre to edges
Inventor: KOPF HELMUT PROF DR
IPC: A63B51/06
Filed: 1977-04-09
Abstract: A tennis racquet has strings (131, 132) which form two layers, one on each side of the frame (12). The strings of the two layers form continuous loops which are located in grooves cut in the edges of the frame. The spacing between consecutive strings is widest in the central area of the racquet and decreases progressively towards the edges. The variation of the spacing of the strings has the effect that the energy absorbed by the racquet is roughly the same no matter which part of the surface is struck by the ball. This means that the rebound velocity of the ball is largely independent of the location of the area of contact with the racquet.
