Inventor: HAID ERICH
IPC: C12N1/08
Filed: 1976-05-21
Abstract: are produced by heating an aq. micro-organism suspension at pH 7-8.5 to 63-67 degrees C, opt. with addn. of a substance, (I), having ribonuclease activity. Heating is continued until 5'-nucleotide content in medium reaches desired concn.

Title: Removal of separating thread from textile prods. - by heating prod. to activate crystals of thread-destroying cpd., e.g. aluminium sulphate, preformed on thread of e.g. viscose rayon
Inventor: HANCOCK MICHAEL TURNER
IPC: D06B11/00
Filed: 1977-08-13
Abstract: Chemical and thermal treatment is used to remove the separating thread in the mfr. of woven, knitted or braided products such as bobbin lace. Before the seperating thread is used, it is immersed in an supersatd. soln. of a crystal-forming cpd. (I) and then subjected to further moisture such as steam to build up water-contg. crystals, and dried. (I) is a cpd. which under suitable conditions can dissolve the thread. The seperating thread is worked into the textile material at the required locations, and the fabric is then subjected to heat in a hermetically sealed chamber to dissolve the crystals and disintegrate the thread. The fabric is then subjected to mechanical vibration or shaking to remove the residual particles of the separating thread. The process allows the fabric to be finished and the seperating threads to be removed fully to give an attractive material. The pref. material for the separating thread is a glossy spun viscose rayon, the super satd. soln. contg. aluminium sulphate and opt. a non-ionic wetting agent.

Title: Improving gliding efficiency of skis - by laminating porous plastics sheet to underside, the pores being subsequently filled with glide wax
Inventor: PENNEKAMP GUENTHER
IPC: A63C5/056
Filed: 1977-10-27
Abstract: Mfr. of plastics runnings surfaces for skis comprises first heat-moulding a semi-finished or intermediate rod. from plastics powder from which thin sheets are then sliced off from which the running surfaces of the skis are cut. The plastics powder is blended with an additive before being hot moulded. The additive is heat-stable or has a structure that it is independent from the plastics matrix when heated, so that it can be removed from or out of the same as the thin sheets are sliced off the semi-prod. The plastics is polyethylene, an endless band being 'pared' and sliced off the intermediate moulding. The heatstable additive is PTFE powder, present at 5-10% based on wt. of the polyethylene matrix. The operation results in a thin sheet with rough or porous surface which will accept and retain a coating of wax thus improving the gliding characteristics of the ski. The thin sheet is finally laminated to the underside of the ski.

Title: Rapid response automatic speed control for vehicle - uses servo control enhanced at higher engine speeds by special circuit
Inventor: FLEISCHER HELMUT
IPC: B60K31/04
Filed: 1977-12-14
Abstract: The speed control for the vehicle uses a monitor to sense the accelerator pedal setting and operate a servo motor on the carburettor. The transmission factor of the servo control is linked to the engine speed so that a larger servo adjustment is provided at higher speeds. The system ensures a rapid response in vehicle speed w.r.t. the accelerator pedal setting, esp. at the higher engine speeds where a set amt. of throttle adjustment produces a smaller torque change than it would at lower speeds.

Title: Hardenable polyurethane compsn. softened with higher alcohol - and ester softener, used esp. for printing rollers
Inventor: ELLIOTT ALPHONSE P
IPC: C08L75/00
Filed: 1978-06-01
Abstract: Compsn. contains (a) a NCO-terminated polyurethane pre-polymer with mol. wt. 400-10,000, (b) a polyol as hardener for the pre-polymer, (c) a 5-26C fatty alcohol, and (d) a phthalate or dibenzoate ester softener.

Use of the compsn. to produce rollers for the printing industry is claimed. The Shore A hardness is 15-35, and remains partially constant. Bleeding of the softener is lessened, and solvent resistance is increased, in comparison with polyurethanes not contg. a fatty acid.
Patent DE-2827158-A1 (DE)
Title: Sausage skin hose clamp - with hinged halves and eccentric cam on hand lever
Inventor: MUDDER HANS
IPC: A22C11/12
Filed: 1978-06-21
Abstract: Sausage skin hoses, made up of a material such as nylon tube, lose their stability if handled without a tubular core on which the hose is gathered in close corrugations. Their transfer to the filler spout requires manual handling and loses productive machine time. This can be saved if the hose is pushed complete with tubular core over the filler spout and is held at the machine end by a split clamp with a hinge at one end and an eccentric cam with operating lever at the othr end. Such a clamp can be readily made by any user to save valuable time.
