Title: Steam dampening unit for shoe mfg. machines - has pressure chamber with safety valve controlling steaming time
Inventor: GRUBER ERNST
IPC: A43D11/14
Filed: 1978-07-29
Abstract: The upper leather material of the shoe receives a moisture content of about 14% to facilitate shaping and production. A pressure chamber (1) is closed by a seal (2) so that it withstands a pressure of about 2 bar. This pressure is accurately measured by a safety valve (8). The steam supply continues until the safety valve (8) opens so that an even damping is possible without additional operations. After placing the uppers on the grids (3) the sealed door (4) is closed and the uppers are moved past a conventional steam producing unit. The counter piece is pressed against the snap coupling (5) and the plastics container holding the uppers is filled with steam until it escapes from the valve (8).

Title: Automatic focus control for camera - has variable angle mirror to reflect received light from subject to photocell
Inventor: STUMPF FRIEDRICH DIPL PHYS
IPC: G02B7/32
Filed: 1978-12-22
Abstract: An automatic focus control for a camera has a measuring beam of light directed at the subject (6) with the reflected beam picked up by a rotating mirror (5) of fset from the axis of the beam. The mirror reflects light to a photocell (2). The angle of the mirror is taken as a measure of the spacing of the subject. A feedback control with phase shift register and flip-flop switching circuits provides a rapid determination of the angle of the mirror corresponding to max. signal, and hence the distance setting. The circuit is designed to reach the setting rapidly without hunting.

Title: Light mineral oil products separator - with inflow stop valve actuated by interface sensor
Inventor: HUNKEL LUDWIG
IPC: B01D17/00
Filed: 1979-07-16
Abstract: Light mineral oil products such as petrol, fuel oil and lubricant from garages and airports are sepd. from water in separate or combined tanks for use as a mud pit, a separator for specific gravity separation of the liquids, and a collector for the light liq. A stop valve at the inflow is closed when either the interface in the second or the level in the third compartment reaches the elevation of a threshold sensor. This prevents contamination of the drainage system by oil or petrol and eliminates turbulence between the liq. layers.

Title: Switching circuit for microprocessor with set memory and register - enabling use of lower programming language to interpret higher programmed language and speed multi-programming branches
Inventor: SCHLANG MANFRED DIPL ING
IPC: G06F9/44
Filed: 1979-09-24
Abstract: The microprocessor contains an interpreter memory (5), to hold a set of commands in a lower programming language, and a user-program memory (4) to hold the statements of a user program in a higher programming language. An interpreter controls the processing of user-program statements in the higher language using sequences of commands in the lower language. A permanent memory (7) holds the addresses for the interpreter and its inputs are connected to those lines of the databus (1) occupied by the operation code of the higher language. The permanent memory's outputs are connected to the data inputs of a transfer memory (8).. Multiprogramming branches are realised more quickly by using a lower programming language to interpret a higher programming language.

Title: Granulation and drying protein and fermentation prods. - by spraying conditioned soln. or suspension into a vortex bed maintained with hot air
Inventor: BERGMANN HORST DIPL ING
IPC: A23J3/20
Filed: 1979-10-13
Abstract: Simultaneous drying and granulation of solns. or suspensions of fermentation prods. or proteins, comprises first conditioning for 60 min at pH 3.5-8(4.5), is not >100 (49) degrees C, then spraying into a vortex bed drier with pressure increase of 0.196-10mPa. The soln. or suspension has solids content not >40 (12) wt. %. The drier is supplied with air at 500 degrees C and fitted with a discharge screen. The resulting granules are cooled to 35 degrees C then subsequently dried to 4 wt. % moisture. Subsequent cooling is pref. with 3 wt. times (on prod. throughput) of air at ambient temp, which is then passed to the main air stream. The granules are useful for animal feeding or, after processing, in human nutrition. Less energy is required (less heat lost in the off gases) and no thermal deterioration of the prod. The granulate is dust, free, free-flowing, of high bulk density and does not tent to block nozzles etc.
Patent DE-2942812-A1 (DE)
Title: Safety cut=out for tumble-drier - with dual-action thermostatic heater switch which also curtails program execution
Inventor: BOECKER HEINRICH ING GRAD
IPC: D06F58/50
Filed: 1979-10-23
Abstract: In a tumble-drier for laundry, having a thermostat in the hot-air conduit which switches off the heater if the temp. exceeds a pre-set value, due, e.g. to throttling of the air-flow, the thermostat is so connected to the machine controls that its operation causes a rapid-return to zero of the program timer, to prevent the heater being switched on again as the thermostat probe cools. This prevents repeated switching off and on of the heater before removal of the blockage and prevents possible damage in the interim, partic. if the machine is long unattended.

All electrodes (7) are pref. fed with electric power via a controller supplied with programmed data, e.g. via punched or magnetic tape. Despite the irregular distribution of paths (4) on board (5), all the paths can be provided with the same thickness of an electroplated metal coating.

Title: Damped mounting for high-speed spindle assembly - has resilient sleeves holding spindle within resiliently-mounted spindle housing
Inventor: KULLMANN HELMUT
IPC: D01H7/04
Filed: 1979-11-08
Abstract: A vertical, high-speed spindle assembly for continuous operation in spinning or twisting frames has a fixed, hollow spindle set in an inner pair of vibration-damping, metal-rubber sleeves of differing hardness within a flanged housing which is seated in an aperture in the spindle rail on an outer pair of flanged, resilient vibration-inhibiting bushes. The bushes are pressed into the aperture from top and bottom and are compressed between the flange of the spindle housing and a washer and nut which secures the housing to the spindle rail. The bobbin is carried on a rotating sleeve mounted in a lower, fixed ball-bearing and an upper, axially-movable, spring loaded ball-bearing by which axial play of the rotor can be eliminated. This construction absorbs horizontal and vertical vibrations, and enables the spindles to run continuously for weeks or months without attention.
