Title: Tool for mfg. overmoulded tapering knife handles - by supporting a flat shank with key profiles near the free end
IPC: B29C45/14
Filed: 1975-07-28
Abstract: Complementary knife blade and moulding tool designs are for shaping secure moulded plastic (polyamide) handles which taper in profile towards the root of the blade. The knife blades incorporates an integral flat metallic shank. The free end of the shank has peripheral recesses and a tab end which can be clamped and supported between the two halves of the mould tool. The handle is securely anchored by the recesses. Differential thermal contraction/expansion occurs preferentially parallel to the taper over the shank so that any consequent exposure occurs at the blade root, where it is less obvious than it would be at the free end of the handle. Because the shank is clamped at both ends to inhibit deflection, the handle cross-section is symmetrical and not prone to subsequent lateral warping.

Title: Bearing race chipless forming - uses blanks with plain inner surface shaped outer surface and profile roller acting from inside
Inventor: LAPIN V V
IPC: B21H1/12
Filed: 1975-11-20
Abstract: The chipless forming of bearing races uses blanks with plain ineer surface, but with the outer surface of approximately the same shape as the expected inner surface of the finished product. The formin tools are chosen in such manner that, under pressure, applied from outside, the inner surface is given the desired shape. Preferably the rolled blank is produced in a roller mill with rotary rolls adjustable in radial direction. The outer roll provides the inner surface shape, while the outer surface is shaped by the inner roll so that only relatively small deformation force is needed for polishing.

Title: Mixing process for red wine-making tank - with immersed pump for intense mixing without rupture of marc layer
IPC: C12G1/032
Filed: 1975-12-10
Abstract: Mixing process for grapes in a wine-making tank is effected by means of ahigh power pump. The grapes soon separate into a lower layer of juice covered by a layer of floating skins. In making red wine the substances contd. in the skins esp. the colouring matter and the tannins, must be extracted as completely as possible. The pump is lowered by the mobile lifting block through a hole in the top of the tank. The pump inlet is situated above the floor while the outlet is connected to an ejector which carries an adjustable yoke with a deflecting cone fixed to its centre. When the pump is started, the juice is sucked into the pump and forced out in a cone-shaped stream against the base of the layer of skins. All the intense agitation and percolation of the skins by the juice is effected without breaking into the CO2 atmos. which surmounts the layer continuous protection from the air is thus assured. As only the liq. passes through the pump, the skins are not ground by passage through the pump or by contact with a bladed or paddle wheel. The layer of marc is not disturbed by the mixing process and seals off the air. The treatment improves and facilities the process and a high quality wine is obtd. having constant properties.

Title: Heating and air conditioning system with storage vessel - utilises constant temp. heat storage using latent heat of fusion
IPC: F25B30/02
Filed: 1976-10-04
Abstract: The system is used esp. for heating or air conditioning of rooms, and for generating hot water and for drying purposes, in industry or agriculture.

Title: Building thermal insulation panel support - uses aluminium sections which interlock with point contact to minimise heat conduction
IPC: E06B3/263
Filed: 1976-10-22
Abstract: The thermal insulation panels forming part of the wall of a building are covered with metal sheets (12). The panels are connected to each other and supported by the aluminium sections which interlock but make only point contact with each other.
