Patent DE-2921408-A1 (DE)
Inventor: DUERR HERBERT DIPL ING
IPC: B02C17/16
Filed: 1979-05-26
Abstract: A de-aerating agitating mill, especially for paints, pigments and the like in which the mixing chamber is closed off from a discharge chamber which may be subjected to reduced pressure. The closure is effected by a separator device consisting of a central disk which is attached to the stirrer or agitator shaft and rotates in a hole within a stationary part of the casing. A narrow, annular gap between the periphery of the disk and the rim of the hole acts as an outlet channel through which the ground or mixed stock is extruded. The shear stresses exerted on the stock rupture the material and burst any air bubbles which are then removed by the vacuum.

Patent DE-2930344-A1 (DE)
Title: Folding machine for textiles - having hinged shutters which handle large items without preparatory straightening and spreading
Inventor: STEINERT EBERHARD
IPC: D06F89/02
Filed: 1979-07-26
Abstract: Appts. for folding textiles of varying shapes and dimensions comprises a pair of longitudinal shutters which hang down on either side of a central working surface at an acute angle from the horizontal, which swivel to a horizontal position around axes alongside the fold axes, where a series of clamps hold the incipient folds produced by swords moving vertically downwards at right angles to the fabric surface; the shutters, at slightly different heights, slide horizontally across the full width of the working surface to produce two longitudinal double folds, then withdraw to allow a series of transverslyy-hinged flaps between the shutters to effect the transverse folds synchronously with the phased released of the longitudinal clamps. The machine handles large, awkward items with relative ease, and in a small space, as they are not laid out flat before folding commences. It is not restricted to one type or size of goods and works at high speed with a single operative.

Patent DE-2951172-A1 (DE)
Title: Magnetic tape speed discriminator - allows tape speed to be controlled during replay for recordings made at different speeds
Inventor: NIWA YOSHIKAZU
IPC: G11B15/087
Filed: 1979-12-19
Abstract: A frequency discriminator circuit is used with tape recording systems to provide automatic identification and control of tape speed. The system allows a tape recorded at one speed to be identified and played back at a different speed. The system uses a reference oscillator (1) that is controlled by one tuning stage (1) that refers to one tape speed and another tuning state (1a) that refers to a second tape speed. A control stage (2) operates over a servo to control the oscillator. A frequency divider (3) consisting of two coupled counter stages generates output frequency based upon the tape recorded control frequency. The control signal is amplified (4) and is compared with the divider output. Depending upon whether the tape has been recorded at a faster or a slower speed than the replay speed, the comparator output will be high or low. This signal may be used to provide automatic speed control.

Patent DE-3007422-A1 (DE)
Title: Telephone tariff system - produces tariff pulses from stored control commands to eliminate effect of delays
Inventor: FRANK REINHARD DIPL ING
IPC: H04M15/04
Filed: 1980-02-27
Abstract: The telephone system has time data stored in memories and specifying a time point lying within the selection time interval at which the selection of the affected memory should occur to form a tariff count pulse. A memory adds a time value to this time data which is stored assigned to a connection-specific switching device and specifies the wanted time spacing between two consecutive tariff count pulses. The memory stores the resulting sum. This sum is selected at a latter moment by the selection device. The advantage of storing these times lies in eliminating the effects of delays.

Title: Hot foil embossing appts. - has adjustable feed obtained by variable position of stops in oscillating mechanism
Inventor: SCHNEIDER GEORG
IPC: B41F19/02
Filed: 1980-11-26
Abstract: Device for infinitely adjusting the feed of a strip-shaped hot embossing foil in a hot foil embossing appratus is designed to produce an adjustable idling zone or backlash in the drive connection. A variable speed motor drives an endless belt, which in turn drives a crank wheel carrying a crank pin connected by a link (116) to a second crank pin (114) on a cam disc (113). This cam disc and a gear wheel (102) are mounted freely rotatable on a shaft (17, 101), which also carries, keyed to it, a drive disc (111); the drive disc is in the form of two symmetrical actuating segments (108, 109) with vacant segments between them. A pin or dog (112) fixed in the cam disc (113) penetrates into one of these vacant segments, while another pin or dog (104) fixed to the adjustable gearwheel (102) penetrates into the other vacant segment. A return lever (119) keyed to the shaft (101) is connected to a tension spring anchored to the machine frame. The shaft also carries, idling on it, a coloured foil conveyor roller (6). The device enables an infinitely variable feed to be achieved while at the same time excessive loading of the foil is avoided.

The other end of this drilling is connected by a second valve (20,22,23) and a transverse drilling (25) to the first ram chamber (4). The second valve is mounted in the drilling (18) and is pressure-operated by a control piston (28) working in a chamber connected by a drilling in the piston rod (29) to the second ram chamber (3), on the other side of the piston. The first valve is formed by the mouth (15) of a transverse drilling (25) in the first ram chamber and a sealing ring (30) fitting round the piston rod.
