Title: Phase locking control loop for digital signals - reception range of control loop in frequency divider limited at certain counts
Inventor: HEGELER WILHELM DIPL PHYS
IPC: H03L7/099
Filed: 1974-11-09
Abstract: An input signal with a frequency (fM) is placed at one input of a first phase comparator. The other input is provided with a signal with a frequency (fL) produced from a constant signal frequency (fF) by means of a frequency divider. The dividing relationships is a variable by means of voltage control. It is controlled by the output signal of the first comparator. The signals of frequencies (fM and fL) are conducted to a second phase comparator. One of the two frequencies is rotated by nearly 90 deg. by means of a 90 deg. phase shift component. The output of the second comparator is fed to a forwards-backwards counter connected to a logic circuit by at least two outputs.

Title: Rotor vibrator for grain conveyor - has unbalanced rotors angularly spaced and restrained by friction washers under plate
IPC: B06B1/16
Filed: 1974-11-29
Abstract: The vibration is used to move grain along a conveyor and is induced by two pairs of unbalanced rotors, one at each end of a common axle. The amount of the vibration is set by adjusting the angle between the two rotors of a pair. They are then kept from relative movement by the pressure exerted on friction washers by a metal ring at the end of the axle. A plate braces the metal ring against the end of the axle under the action of a locking lever eccentrically mounted in forks bearing on the axle, and so holds the unbalanced rotors fast to each other and to the axle.

Title: Shaping of carpet strips with thermoplastic backing - using rubber cloth and evacuation of the press mould
Inventor: BRATSCH KURT ING
IPC: B29C51/08
Filed: 1975-01-15
Abstract: Shaping of carpet strips with thermoplastic coatings e.g. for fitting in automobile bodies, by thermoplastically moulding the carpet blank in an automatic moulding unit, suitably consisting of a wind-off block, an intermittently operating feed and sectioning station, a heating and moulding station, and by automatic removal by a suitable device. More especially, the final shaping in the moulding station is carried out by means of vacuum and a rubber cloth.

Title: Electric controller with selectable manual and automatic modes - has mode selection knob which also adjusts potentiometer
Inventor: GRIEGER PETER DIPL ING
IPC: G05B7/02
Filed: 1975-02-27
Abstract: The controller is mounted in a simple rectangular chassis on the face of which are a set point dial, a controlled variable-amplitude display and a mode selection knob. This knob may be moved laterally to select one of the two modes. The knob is attached to a shaft (10) inside the chassis. At the end of the shaft is a potentiometer. Rotating the knob affects the potentiometer setting, providing an output for the control circuit. Lateral movement of the knob results in the shaft actuating a pair of switches (18, 19) which are connected to a relay driving circuit containing two or more relays, which give the appropriate circuit changes when a manual to automatic change, or vice versa, is made.

Inventor: DEININGER ROLF DR
IPC: A61K36/8962
Filed: 1975-06-24
Abstract: In a process for recovering a therapeutically active substance from garlic (Allium sativum L.), an alcoholic extract of stored, ripe cloves of garlic is converted into an aqueous solution and treated with ions of lead, copper and/or cadmium in excess; the resulting precipitate (contg. excess Pb, Cu or Cd ions) is removed from the solution; and the active substance AA is isolated by adding active charcoal powder to the solution, eluting with alcohol, and concentrating. The substance sativin I can be isolated from active substance AA by adsorption chromatography on cellulose powder with butanol/ethanol/water 10:7:3 v/v/v as eluant. Active substances AA, sativin II (which can also be isolated from AA) have thrombocyte aggregation inhibiting activity (sativin II>sativin I>AA), and can be used for the oral or parenteral treatment of infarct, embolism and thrombosis.

Title: Water stop and waste valve - includes filter with automatic shut-off when filter is removed
Inventor: BOTNICK IRLIN
IPC: F16K24/02
Filed: 1975-06-28
Abstract: A check valve for water has a filter (F) which can be removed from and inserted into the valve body (B) through its open end into the filter position between the section (13C) and the discharge. A system to operate this part of the valve includes a removable sealing closure (P) for the open end of the body.

Title: Ion exchange system for liquids with varying impurity levels - having reserve vol. of resin with fixed amts. of regenerative soln.
Inventor: PALM HANS DIETER
IPC: B01J49/05
Filed: 1975-11-24
Abstract: Continuous treatment of liq. media with fluctuating level of ionic impurities involves passing the liq. through two types of bed to remove anions and cations. These absorb the unwanted ions, the beds subsequently being regenerated with suitable reagents. Each bed contains a certain reserve of exchange resin. The interval in the operating cycle and the vol. of resin are so selected that no variation the output quality occurs. Also the loading interval can be abridged without decline in quality, the same quantity of regenerating reagents being used however in the regeneration phase. Used in purifying liquids e.g. water where marked fluctuations in impurity level can occur. In this process, provided the deagents are set for average conditions, the cycle time can be adjusted for varying feed conditions.

Title: Low pressure pneumatic diaphragm switch - is pressure dependent and has diaphragm only weight loaded
Inventor: PAPP GEORG
IPC: H01H35/34
Filed: 1976-02-27
Abstract: The diaphragm of the pressure-dependent switch for low pressures is completely and/or mostly weight loaded. The diaphragm preferably lifts a magnet and moves it into the sensitive region of a reed contact. Alternately it may lift a conductive surface forming a capacitor electrode, thus bringing it nearer to a stationary counter surface. In such instance the capacitor electrode is pressed against the counter surface without intermediate insulation with a possible galvanic contact. The diaphragm may be, at least partly, in the form of a elastically deformable conductive surface, movable against one or several counter surfaces. A flow bypass may be associated with the diaphragm in an adjustable manner.
