Title: Medicament intake control appts. - has clock operating signal and making vessel ready at preset times, reset only after use
Inventor: SIEGEL MAX
IPC: A61J7/04
Filed: 1978-05-03
Abstract: The apparatus which gives exact intake of medicaments in precise doses and at predetermined times, incorporates a timing clock which can be set to operate several times within a 24-hour period, when it activates an acoustic and/or optical signal, simultaneously making ready a medicament vessel for use each time. Only after the prepared medicament has been removed can the clock be reset to operate at the next appropriate time, to allow the process to be repeated. The clock can be arranged to operate at least once and at the most eight times in a 24-hour period, the number of medicament vesses varying between 1 and 45 inclusive.

Title: Brake for swivel castor - has swivel brake independent of wheel brake for manoeuvring in confined spaces
IPC: B60B33/02
Filed: 1978-05-13
Abstract: The swivel castor is fitted with a wheel brake as well as a swivel brake, with both brakes applied by a common brake lever (22). A separate pedal lever (36) serves to operate the swivel brake independently of the common brake. The independent operation of the brakes enables the castor supported vehicle to be moved out of confined spaces after the swivel brake is released. It can then be stabilised for a set direction by applying the swivel brake.

Title: Dual purpose luggage combination lock - has grooved bolt through casing and slide holes for attachment to fixture
Inventor: LEHMANN RUDOLF
IPC: E05B37/02
Filed: 1978-06-16
Abstract: The lock, especially for luggage, has a mechanism in a housing with a set of numbered rolls and an adjustable slide fixing or releasing an insertable closing unit, according to the way the rolls are set. One or more holes (11, 14) in both housing (10) and slide (13) are accessible from the front.

Title: Static inverter supplying small compressor from battery - has PTC resistor in series with resonant circuit tuning resistor
Inventor: SCHIRP WILHELM DR ING
IPC: H02M7/539
Filed: 1978-07-12
Abstract: The static inverter has a PTC resistor (8) in series with the resistor (4) that determines the frequency of oscillation. Alternatively the resistor determining the frequency of oscillation may be shunted by a variable resistor in series with a PTC resistor. The two series resistors may be shunted by a triac switch that turns on and off as the voltage across the resonant circuit's coil rises and falls. The two series resistors are connected between a tapping on one primary winding of an output transformer and one pole of the battery. The ends of this primary are connected to the bases of the oscillating transistors. The inverter may be used for driving small compressors in coolers for caravans, etc.

Title: Addressing circuit for store in telephone system - has decoder selecting several memory modules simultaneously during testing to reduce test time
Inventor: FAKLER WOLFGANG DIPL ING
IPC: G11C8/14
Filed: 1978-12-07
Abstract: The addressing circuit has a decoder (Q) decoding the incoming addresses for the column lines (1-8) of the store. The store consists of orthogonal column and row lines with memory modules (Sa) at their cross-points. The decoder executes different functions during testing and normal operation. In normal operation, the decoder selects a memory module. In the test mode, the decoder selects several memory modules simultaneously via several column lines in order to keep the time required for testing as short as possible. The decoder is therefore best realised as a memory itself and responding to control words.

Title: Replaceable cutting edge for turning tool - has clamping bolt for transverse locking screw to exert force on main bolt
Inventor: ECKLE OTTO
IPC: B23B27/16
Filed: 1978-12-09
Abstract: A turning tool has a body (1) with a replaceable cutting edge (3) which fits in a recess (2).

A locking screw (11) is screwed into a transverse hole (10) in the bolt (4). The end of the locking screw abuts against a sloping face (14) so that a downward force is exerted on the bolt (4). At the same time the axial force exerted by the screw (11) tends to swing the bolt (4) about the edge of its maximum diameter (8) and press the cutting edge (3) against the side of the recess (2).
Patent DE-2853808-A1 (DE)
Title: Hydraulic trailer brake for utility vehicle - has priority for brake circuit and pressure-controlled supply to other circuits
IPC: B60T17/18
Filed: 1978-12-13
Abstract: A hydraulic brake control valve for a trailer has a spring-loaded distribution valve (1) which is sprung into the brake priority setting. Here the fluid from the pump (P) is fed into the pressure reservoir (2) via a non-return valve (R) and to other hydraulic accessories (H) via a flow restriction. When the reservoir has sufficient pressure a monitoring valve (6) operates a solenoid (8) to pull the distribution valve into a second setting in which the brakes and other circuits are equally supplied. The spring distribution valves provide a rapid acting control to ensure that as soon as the reservoir loses pressure, through braking, the brake priority setting is activated.

Title: Pressure control for hydraulic steering servo - includes supply to servo pumps progressively restricted with increasing speed
Inventor: DEININGER HORST DIPL ING
IPC: B62D5/32
Filed: 1978-08-05
Abstract: The control valve is for a hydraulic steering servo. There are two pumps which draw fluid from a double reservoir and with a control valve (17) in the line between the reservoir and the pumps (4, 5). The valve has a single sliding element with differential valve seats and a single control spring (38). The return lines to the reservoirs have simple flow restrictions (18, 19). The flow of fluid to the pumps is continuously restricted as the vehicle speed increases by the increase in the return flow pressure displacing the valve and thereby preventing undue pressure build up from the pumps.
Patent DE-2857588-A1 (DE)
Title: Pole arrangement for synchronous electric motor - has opposed pairs of stator poles chamfered at air gap region to improve running action of rotor
Inventor: DROEGE CARSTEN ING GRAD
IPC: H02K21/16
Filed: 1978-09-28
Abstract: The synchronous electric motor is for control and measuring purposes and also for the drive for a labelling machine or for an indexing drive. It has a permanent magnet rotor (7) with poles which are two less in number than the pole pieces carrying the windings (8, 9) for the stator. Thus the rotor can have six poles and the stator has eight. Two (3) adjacent stator poles are chamfered at one side, and the two stator poles opposite them are also chamfered. This increases the air gap, and the chamfers of each pair are on the outer corners. This improves the running action of the rotor, and when the power supply is cut off, there is a stronger holding force on the rotor.

Title: Low temp. heat treated spheroidal graphite cast iron - is given pearlite-sorbite structure by austenising treatment
Inventor: MUEHLBERGER HORST DIPL PHYS DR
IPC: C21D5/00
Filed: 1979-02-06
Abstract: Spheroidal graphite cast iron having a ferritic structure is given a pearlitic-sorbitic structure by applying an austentistic heat treatment at 760-910 degrees C (820-840 degrees C) using a holding time of 10-60 min. (20-40 min.). The cast iron is subsequently cooled in moving air. Method does not involve high temps. for the heat treatment which is carried out 150-180 degrees lower than usually required. The holding time is only 25% of the min. time required when using conventional methods. This prevents a reduction in energy consumption, while throughput is increased fourfold. Scale formation is also reduced.
