Title: Sensor for fluid level - uses electrically heated thermistor with sudden change from high to low resistance at temperature rise
Inventor: KAHN DAVID
IPC: G01F23/24
Filed: 1974-09-13
Abstract: A level sensor for producing a warning signal if the brake fluid for motor cars drops below a danger level consists of an electrical heating element (22) which is coupled by a heat transmitting connector (27) to a resistor (24). The latter is made of a material which suddenly changes from a high to a low resistance at a certain temperature. The sensor is attached by the fitting (26) to the brake fluid container. The preferred material for the resistor (24) is Ti3O5 which has a transition temperature of 165 deg.C. This eliminates the high temperature rise required by ordinary thermistors and has a desirable self-locking effect once a dropping fluid level has caused it to respond.

Patent DE-2457073-A1 (DE)
Title: Pattern generator having tactile pins - supported in projected position by oblique locking pins
Inventor: SCHOENHERR KLAUS-PETER DIPL IN
IPC: G09B21/00
Filed: 1974-12-03
Abstract: In apparatus for generating tactile signals, e.g. Braille patterns, reading pins (K.1) are arranged so that their upper ends project above or lie below a reading surface. The lower ends of the reading pins engage upper ends of respective locking pins (K2) which lie on axes oblique to the axes of the reading pins. When a reading pin is raised electromagnetically (S1) the associated locking pin rises against spring pressure (F1) and the lower end of the reading pin becomes lodged against the side of the locking pin which thereby prevents the return of the reading pin. When the locking pin is withdrawn electromagnetically (S2) the reading pin lowers under gravity (F1) into the withdrawn position.

Title: Belt-type casting machine control - using heat detectors insulated from coolant for the belt
Inventor: PETRY CHARLES JOHN
IPC: B22D11/06
Filed: 1974-12-11
Abstract: In a method and appts. for controlling a belt-type continuous casting machine, in which the back of the belt(s) is cooled by a continuous high velocity flow of cooling liquid and the casting surface of the belt(s) has an insulating protective coating, the improvement is that the desired range of the molten metal pool in the input region of the machine is predetermined, a series of heat detectors are contacted with the back of the belt along the desired range of pool position and arranged to interfere minimally with the coolant flow and to be insulated against the coolant flow, the responses from the detectors are monitored to determine the pool position and the feed rate of the melt is maintained matched with the machine speed to keep the pool position in the desired range. (This is a division of 3864973, 14024W). The method can be used in twin-belt or wheel-and-belt casting machines and allows continuous monitoring of the machine to prevent overflow splashing of the metal.

Title: Flat bed press pulsed feed - has conveyor belt fed charge table to insert into press and withdraw completed charge
Inventor: STEGHERR LUDOLF
IPC: B27N3/22
Filed: 1974-12-28
Abstract: The system is for pulsed input and withdrawal of plate type e.g. hinged pressed articles into a flat or surface press.

Title: Thermoplastics continuously extruded and cooled through nozzle - with eccentric infeed of water giving simplified arrangement
Inventor: HUNKE FRIEDRICH
IPC: B29C48/05
Filed: 1975-01-28
Abstract: An apparatus for the continuous production and cooling of thermoplastics in the form of a thread, which leaves the discharge nozzle and shortly afterwards passes through a cooling nozzle, has the cooling nozzle constructed as follows: the coolant enters the cooling nozzle through a pipe, laterally at an acute angle to the thread of material; the pipe curves round progressively until, when at the centre of the cooling nozzle, its outlet points in the direction of flow of the material, the pipe being pref. tangential to the thread at this point. The arrangement is much simpler and cheaper than a cooling nozzle with an annular coolant channel surrounding the passage for the thermoplastic thread. In spite of the asymmetry, the thread is not disturbed by contact with the mouth of the pipe and does not adhere to the pipe. The contact stabilise longitudinal oscillations of the thread, thus promoting greater uniformity in its cross-section. The consumption of cooling water is reduced, by about 50%, for a given value of pulling force applied to the thread.

Title: Machine for mfr. of plastics foil or coatings - has pair of melt rollers into whose nip preplasticised moulding cpd is charged
Inventor: SCHLOMACH ECKART DR ING
IPC: B29C43/24
Filed: 1975-06-26
Abstract: A machine for the mfr of plastics foil or coatings has a pair of melt rollers defining a nip into which moulding cpd. that has been worked-up by a pre-plasticising unit, is fed. A melt-roller whose circumference protrudes partly into the arcuate opening of a storage tank is arranged above the pair of melt-rollers. Beneath that melt-roller there is a stripper device. The device results in prodn. of plastics foils or coatings that are homogeneous and free from flaws. Suitably a metering or dosing device is arranged at the exit edges of the storage tank, adapted to regulate the amt of moulding cpd. being discharged. The device is esp. suitable for feeding a constant amt of moulding cpd. over the entire length of the melt-roller nip. This reduces unbalanced radial stress on the pair of rollers and ensures even thickness of the resulting foil or coating.

Title: Continuously processing all types of goods, esp. textiles - on outer surface burl woven conveyor, guided by rake
IPC: D06B23/04
Filed: 1975-07-24
Abstract: An arrangement for continuously processing goods of all kinds esp. textiles,w ith fluids or gaseous media, consists of an endless permeable belt turning at each end on guide rollers and supporting the goods during their passage through the treatment zone. The belt is woven with parallel length wave running lines of burls on its surface. These are arranged to lie on the outside surface of the sieve belt and a guide having a row of sawtooth openings which straddle the rows of burls keeps the belt in alignment. On the undersurface, a permeable support such as a perforated plate may be fitted to help support the load on the belt. The belt retains the advantages of belts with burls without the need to machine grooves in the guide rollers and without the rapid wear of the belt when it runs on a support plate in a long machine.

Title: Eyeball contact lens centring support - is of soft material but has opening over pupil for hard contact lens
Inventor: KILB FRIEDRICH
IPC: G02C7/04
Filed: 1975-09-11
Abstract: Eyeball contact lens centring support made of soft material has a free opening over the pupil for a hard contact lens to be fitted.

Title: Screw injection moulding machine - with injection pressure controlled in inverse ratio to hydraulic screw drive motor torque
Inventor: NEUREUTHER JUERGEN
IPC: B29C45/50
Filed: 1975-10-06
Abstract: In machine, partic. for thermosets, the screw which has no return flow blocking device is driven by hydraulic motor. The injection press. exerted by a hydraulic actuator, is adjusted as a function of the motor torque output in such a way that it is reduced when the torque rises and increased when the torque drops. This results in a redn. of the overall cycle time required. No starting phase is needed, resulting in time savings when the batch numbers are small and the machine operates in one or two shifts per day. No complicated control elements are required.
