Title: Hot channel injection nozzle for injection moulding machine - has increased useful life and develops low amt. of frictional heat
IPC: B29C45/27
Filed: 1979-10-09
Abstract: A hot channel injection nozzle for a plastics injection moulding machine comprises a cylindrical nozzle body, having an outlet opening at one end and a cover at the other end, which is mounted coaxially about a tubular nozzle core which carries an external annular electrical heating element. The core has a tip, with one or more openings for passage of plastics, which projects into the nozzle body outlet opening. Small surface area abutments clamp the core at its ends, leaving an annular air gap between the nozzle body outlet opening and the cover. The novelty is that (a) the core consists of two parts, a main core made of electrolessly nickel plated beryllium alloy of hardness 70-75 HRC and a core tip which, together with the nozzle body, is made of high chromium steel of hardness 57-64 HRC; (b) an air gap is formed between the inner wall of the nozzle body and the end face of the main core nearest the nozzle body outlet opening; (c) the inner wall of the nozzle body is paraboloidally concave in the region of the core tip and merges into a tapering outlet opening with sharp terminal edges; and (d) the core tip projects beyond the outlet opening. The nozzle is scratch and acid resistant. Local overheating of the plastics by frictional heat developed in the nozzle is avoided and the heat produced by the nozzle is carried forward as far as possible in the region of its outlet opening. The nozzle has a useful life of up to 400,000 injections compared with about 3,000 injections for conventional nozzles.

Title: Encoded data transmission over line switching junction - sequentially coding message or address data independently in new, single phase processing train
Inventor: RAUCH WALTER DIPL ING
IPC: H04L9/00
Filed: 1980-05-08
Abstract: Data are transmitted in ciphered form from a sending unit (DEE1) over a line switching junction (KN) to a receiving unit (DEE2) via sending (ST1) and receiving (ST2) trunks. At least the address data are deciphered before they reach the switching junction (KN) where the path to the receiving station is to be set up. This is done by providing a data gating switch in the cipher units (SG11,SG32) as well as in the decipher units (SH22,SG42) responsive to start or finish codes in data groups of the message stream. By means of the data switch the address and routing signals are first ciphered on application of a first instruction code (preamble), whereas the message data are ciphered in a different way by application of a second instruction code which, moreover, is phased into the data stream itself between the address signal group and the message signal group within the cipher unit (SG11) by storing and delaying the latter by at least the number of bits contained in the second instruction code. The address data are recovered in a unit (SG22) but reciphered in another unit (SG32).

Title: Rigid foam esp. polystyrene articles - have almost sintered surface zones of high strength and wear resistance
Inventor: WALSER ALEXANDER
IPC: B29C44/56
Filed: 1980-09-23
Abstract: The surface quality of rigid foam plastics articles, e.g. of polystyrene, is improved by heating the boundary surfaces during the foaming operation to a higher temp. than would be necessary for the foaming. This leads to a commencement of sintering in the outer layer of material. Surfaces produced as above have, in the surface zone, fine granulate pref. of a higher density. This method enables objects to be produced having surfaces which are considerably more resistant, accompanied by a reduction in the raw material required.

Patent DE-3100241-A1 (DE)
Title: Packaging apparatus
Inventor: WELLS ROY EARL
IPC: B65B51/04
Filed: 1981-01-07
Abstract: In a packaging machine, two wires are introduced, pieces of predetermined length of these being cut off and first shaped into U-shaped staples having indented U-shaped transverse webs which are then clamped at a distance from one another around a tie in a tube formed from a flexible packaging foil and filled with the product. The packaging machine has a staple-shaping mechanism which successively forms pairs of U-shaped staples provided with an indentation from wire pieces of predetermined length, each pair of staples being introduced on an anvil into a device for tying the tube and for clamping the staples, where the staples are removed from the anvil and then clamped around the tie in the tube filled with the product. The indentations in the U-shaped staples serve for preventing the foil from being pinched between sharp-edged corners and for affording the possibility of closing off the capillary orifices in the centre of the tie sealingly, without excessive clamping pressures being exerted on the foil by means of the staples. Ejection rams in the device for clamping the staples have a staple-engaging end face, the shape of which is matched to the indented portions of the U-shaped transverse webs, so that it is possible to retain the staples in such a way that they are prevented from tilting or rotating during the clamping operation. <IMAGE>
