Title: Deep well rotary drill rig - with hydraulically superimposed percussive and/or rotary oscillating motion
Inventor: SIEKE HELMUT DIPL ING
IPC: E21B7/24
Filed: 1975-09-19
Abstract: In a rotary drilling system for deep wells an oscillating motion is superimposed to the rotary motion acting on the drill bit. The frequency of the oscillations varies continuously from a lower to a higher threshold. The oscillating motion is an axially acting percussive and/or a peripherally acting rotary action. This enables the rotary drilling system to be applied to the hardest rocks. A frequency passing quickly through the resonance range produces optimum rock breakage conditions.

Title: Rotating shaft monitoring system using direction discriminator - uses pulse counting system which eliminates superposed interference movements
Inventor: KUGLER ROLAND ING GRAD
IPC: G01D5/244
Filed: 1975-12-05
Abstract: A monitoring system for a rotating shaft of a machine employs a scanning system which eliminates errors caused by e.g. superposed interference movements while scanning a scale checking its direction of movement with a direction discriminator. In case of movement opposite to the specified direction delivery of counting pulses is blocked, and incoming pulses are added. When the movement changes to the specified direction, delivery of counting pulses starts only after the number of delivered pulses exceeds the sum of pulses delivered during movement in the opposite direction.

Title: Combined heat pump and refrigeration system - uses two liquids in outside and inside air contact to control evaporator and condenser
Inventor: BURGER MANFRED R
IPC: F25B30/02
Filed: 1975-12-11
Abstract: A combined heat pump and refrigeration system for air conditioning a building, where the heat from the heat pump is used to drive accessories and the compressor of the refrigeration, has the refrigeration circuit operating under constant conditions in the same directions while two opposed flows of liquid are alternately used for heat exchange with the evaporator and condenser for heating and cooling operations, one flow in contact with external air, the other in contact with air inside the building. For internal cooling. the internal flow is directed to outside, and vice versa for heating, the flows passing through tubes to the evaporator and condenser. The refrigerating circuit of the heat pump is located inside a space which is cooled to lower the temperature of the condenser.

Title: Antilipolytic theophylline-7-acetic acid acyloxyalkyl esters - prepd. e.g. by esterifying hydroxyalkyl theophylline-7-acetate
IPC: C07D473/08
Filed: 1975-03-24
Abstract: New esters of theophylline-7-acetic acids are cpds. of formula (I). In this formula, R is H or CH3; n is 1,2,3 or 4; and "Acyl" is 3-methyl-pyrazol-5-carboyl, 5-n butyl-pyridine-2-carboyl,2 (4-chlorophenoxy)-2-methyl propionyl, 2-acetoxybenzoyl or theophylline-7-acetal. (I) have a range of pharmacological and biochemical properties. In partic. they have highly significant lipolysis-inhibiting activity with the advantage of not giving rise to a rebound effect. Since the esters are only very slowly hydrolysed in vivo, (I) have a prolonged action. Specific cpds. (I) include that in which n is 1, R is H and "Acyl" is 5-n-butyl-pyridine-2-carboyl. This is prepd. e.g. by refluxing 5-n-butyl-2-pyridine carboxylic acid chloride hydrochloride with 2-hydroxyethyl-theophylline-7-acetate in benzene in the presence of pyridine.

Title: Adaptive positional control system - is used for large electric motor and uses signals representing gearing backlash and motor inertia
Inventor: EWE KURT ING GRAD
IPC: G05B19/40
Filed: 1976-01-15
Abstract: An adaptive control method is used for positional drive equipment with a motor (1) and mechanical gearing. It is designed to obviate the need for a braking device and hence the use of parts subject to considerable mechanical wear. The method is partic applicable where large motors are used. For each displacement signals are generated and stored. A quantity is used to represent the drive mechanism delay between a motor switch on a shaft movement to the start of the position element or coupling element motion. A further signal represents the time between motor switch-off and position element or coupling rest condition.

Title: Interlocking ceramic roof tile - has bottle neck shaped indrawn cover fold at tile head to allow extensive lengthways movement
Inventor: LUDOWICI MICHAEL CHRISTIAN
IPC: E04D1/04
Filed: 1976-02-13
Abstract: The interlocking roof tile, pref. made of ceramic substances, has base and cover folded sections, and a head folded section permitting a relatively extensive lengthways displacement. Provision for such movement in rows across the rafters simplifies laying, which can then be carried out by building craftsmen other than roof specialists, and also makes it easier to renovate the roofs of old buildings. The cover folded section is drawn in the shape of a bottle neck in the area of the tile head. In the area of the outer cover fold flank this bottle neck section pref. produces a prepared sunken cover fold plateau. The head folding may incorporate an outside head fold rib, extending beyond the apex line of the bottle neck section in this plateau area.
