Patent DE-2237912-A1 (DE)
Title: Cylindrical back-wash filter energised by fluid stream - filter casing rotated by fluid stream hitting impact plates with cam disc controlling back-wash
IPC: B01D33/00
Filed: 1972-08-02
Abstract: Within a housing a screen type cylindrical filter casing can be rotated around a central shaft. Impingement plates are fitted tangentially at an angle external to the casing. Flow energy generated by the pump turns the casing whenever there is feed. A dog fitted to the casing operates a dog plate at each turn, and via a mechanical linkage opens the discharge valve of the back-wash compartment at preset intervals. An auxiliary flow guide ring may be used to assist rotation. Advantage of regular washing independent of the degree of contamination makes smaller filter areas possible, and absence of auxiliary equipment reduces down-time.
Patent DE-2249903-A1 (DE)
Title: Mechanically-operated mould for applying soles to shoes - using eccentrics to open it for foaming materials
IPC: B29D35/00
Filed: 1972-10-12
Abstract: The shoe upper is positioned in a mould. Below it the spring-loaded base tool rests indirectly on eccentric shafts. The cavity between shoe and base tool is injected by a fixed unit which feeds consecutively a number of moulds arranged round a rotating table. Toggles rotate the eccentrics and are synchronised with injection so that, at a suitable moment after the mould has been filled the eccentrics revolve and the base tool drops, thus permitting the mould to expand downwards. The system is simpler than one using a press. cylinder.

Title: Jolipeptin - antibiotic prepd from aerobacillus species
Inventor: ITO MIKIKO
IPC: C07G11/00
Filed: 1972-11-09
Abstract: The antibiotic jolipeptin (I) m.p. >300 degrees (decompn.) was isolated from a culture medium of Aerobacillus colistinus. For example, benzaldehyde was added to a 200 ml filtrate of the culture medium at pH 8.0-8.6. The ppt. formed was isolated by centrifugation, and extd. with acidic BuOH. The ext. was treated with water to eliminate colistin coexisting in the extd. material. Et2O was then added to the mother liquor, and the ppt. formed was dissolved in MeOH. Insol. contaminants were eliminated by filtration. Addn. of Et2O to the filtrate produced a ppt. which was isolated and dried. I in the dried powder was further purified by Sephadex LH-20 chromatog. using MeOH as the developing agent.

Title: Injection pressure control - by sensing mould pressure and heater or obstructing material flow accordingly
Inventor: PAULSON DONALD C
IPC: B29C45/30
Filed: 1974-01-10
Abstract: The injection pressure in a mould for fluid synthetic resins is controlled by sensing the pressure within the mould and either controlling the temp. of the incoming material or its flow rate accordingly. Temp. may be controlled by heaters located around or projecting into the sprue and flow rate may be controlled by a plug which projects into the sprue. Such control produces highly uniform batches of articles and is simple compared with the prior cut. The pressure sensing means is pref. a plug slidable, in response to the pressure of the injecte material, in a bore leading into the mould cavity.
Patent DE-2404540-A1 (DE)
Title: Burner nozzle cleaner - is operated pneumatically and includes two magnetic valves
Inventor: BATANJAC NEMANJA
IPC: F23D11/38
Filed: 1974-01-31
Abstract: Pneumatic cleaner for burner nozzles includes a magnetic valve which becomes operative in case of power cut, and a magnetic valve which allows passage of compressed air only through no-return valves. Air is introduced at 7-4 atm. absolute pressure, below which the no-return valve is automatically closed by spring action. The employment of air at this pressure helps to ensure that all residues of heavy oil are entirely removed from the system.
Patent DE-2407434-A1 (DE)
Title: Flanged joint for pipe clamping and sealing - uses plain ended pipe without need for screw thread and clamping and seal rings
Inventor: SCHULZ GUENTER
IPC: F16L23/18

Abstract: The flange has a cylindrical extension with a tapered bore. The member to which the pipe is to be attached has a recess which matches the extension, a recess for the seal ring and a smaller concentric bore to match the outside diameter of the pipe. A clamping ring has a bore which matches the pipe and a tapered outside diameter which matches the tapered bore of the flange. When the flange securing bolts are tightened, the flange bore is pushed over the tapered ring compressing it against the pipe. At the same time, the seal ring is compressed so that the pipe is both clamped and sealed.

Title: Height-adjustable draughtsman chair with drop-down sides - also forms saddle-type bench for better support when semi-standing
Inventor: RABAS EDUARD
IPC: A47C9/02
Filed: 1974-05-13
Abstract: The designer or draughtsman's stool is designed in three parts which in the normal sitting position form a square or rectangular seat surface. The two outer parts are hinged to the middle part so that on letting down the outer parts a saddle type bench seat is formed which may be more comfortable for the designer when he is working with large-scale plans, etc. This hinged seat surface is mounted on a height adjustable central column. The height may be adjusted either by means of a hand lever mounted on the column itself or by means of a foot pedal. In plan view the three sections separately have longitudinally tapering sides which are complementary to each other to form the overall rectangular shape.

Title: Heat exchanger with thin walled channels - has thin material strips folded over support rods forming parallel channels (SW221275)
Inventor: HAKOTIE JUHA
IPC: F28D9/00
Filed: 1975-05-24
Abstract: The heat exchanger is used for heating or cooling of fresh air by spent air. Extremely thin metal or plastics foils are used and low pressure differences are involved. The strips held apart by end guides are folded over these guides in a zig zag manner in which the strips are parallel. Every other gap forms a channel for spent air and every other gap between these gaps forms a channel for fresh air flowing in the opposite direction (2, 4). The air, or spent air enters spaces between the thin plates and fresh air or spent air leaves gaps at the other end sideways. The outlet ends for different air types are at opposite ends and point at the opposite lateral direction. The supporting rods are held by springs and compensation elements for accommodating thermal expansions and for ensuring that the strips are held tight.

Title: Microwave oven with controlled power distribution - uses geometrical or electrical change of feed point to vary oven power distribution
Inventor: FRITZ KARL DR
IPC: H05B6/80
Filed: 1975-06-03
Abstract: A microwave oven, in which the power is fed to the cooking area through sets of pairs of oppositely located slots, provided with means to control the relative phases of the groups so as to be able to vary the concentration of the field over the oven space. The generator feed into the centre of the distribution waveguide feeding the two sets of slots is used to effect a concentration of power at the centre of the oven, and a feed antenna is used when a minimum is desired at the centre. By shifting the feed-point by geometrical or electrical means the distribution can be varied between these extremes.
