Patent DE-2166896-A1 (DE)
Title: Appts for conditioning wax - by air free passage into an injection ch
IPC: B29C67/24
Filed: 1971-10-29
Abstract: The apparatus has an air-tight reservoir formed from a material of high thermal conductivity, provided with openings for the introduction of solid wax and a removable air-tight cover blocking the openings. The reservoir has heating and agitating means and vacuum can be applied to it. The lower part of the reservoir is connected to the upper part of the injection vessel which is in the form of a hollow cylinder with a piston. The flow of wax is controlled by a valve. The use of wax free from air makes patterns of improved surface quality in the lost wax process. The wax reservoir is provided with fins to improve heat transfer and agitation is by blades fixed on a rotating shaft which occupy the spaces between the fins. The fins may take the form of diametrally opposed segments.

Patent DE-2204306-A1 (DE)
Title: Mould for foamed articles - with pressure pad to hold half-moulds during foaming action
IPC: B29C33/20
Filed: 1972-01-31
Abstract: Designed particularly for moulding polyurethane foam, the half moulds are clamped together by the contours of the mould shell, and they rest on a pressure pad which is inflated to a pressure greater than that anticipated during foaming in the moulding zone. Before the mould is opened the pressure pad is deflated, so that should foaming not be complete, the increasing pressure is absorbed so that there is no danger to the operators when the mould is opened.
Patent DE-2206868-A1 (DE)
Title: Continuous casting installation guide roll adjusting system - - is self adjusting
Inventor: EISEN JOSEF
IPC: B22D11/20
Filed: 1972-02-14
Abstract: The system comprises drive and straightening rolls between which the casting is passed along a possible curved path with adjustable pressure between the rolls, which is used to control the workpiece thickness. The upper straightening rolls are coupled with displacement probes, the data from which are continuously compared with a set value, servo valves being employed to effect the reqd. adjustments. The lower drive rolls are fitted with pressure measuring probes, the values from which are compared against a set pressure, the pressure difference being corrected by a further set of servo valves. The system ensures close workpiece tolerances and auality and prevents damage to the rolls due to excessive pressure.

Title: Wire rod feeder - accommodating different cycles of shear and subsequent working station
Inventor: SATO HIROKI
IPC: B21F23/00
Filed: 1973-04-26
Abstract: Cut lengths of wire or rod from a shear are fed to the next working station individually by a feeder device that takes account of the relative working speeds of the two machines. Rods from the shear are led singly by a star wheel to an inclined endless sprocket chain with vertical dogs. The sprocket at the lower end of the chain carries weight (W1), and the one at the higher end, mounted on a movable bogey, is tensioned by weight (W2). By choosing W2 > W1 and using limit switches on the movement of the bogey, it is possible to accommodate different working speeds of the shear and the subsequent machine. Entangling of rods is prevented.

Title: Moulding reinforced concrete into U-channels with high walls - carriage-borne upper half of mould having raked leading edge
Inventor: GEIGER HANS
IPC: B28B1/08
Filed: 1974-09-05
Abstract: A U-section channel is formed between a fixed lower mould and a sliding upper mould, with the concrete poured just in front of the upper mould. When the walls of the channel are high, the wet concrete mixture cannot maintain a vertical profile at the leading edge. The inner mould must have a similar profile if the leading edge of the concrete is to be accessible for filling, and the chute (18) which conveys the concrete from the hopper (15) must have its distributing edge directly above this same raked profile. Vertical plates (20a, 20b) at the edges of the upper mould reduce the poured concrete to the required thickness; the section of the upper mould next behind is vibrated to compact the concrete (vibrators 13); behind that again is a non-vibrated section which gives a smooth finish to the work as the carriage slides it forward (rails 2, wheels 5).
