Patent GB-2093658-A (GB)
Title: X-ray image substracting system
IPC: H05G1/60
Filed: 1981-11-19
Abstract: An x-ray source projects successive high and low energy x-ray beam pulses through a body and the resultant x-ray images are converted to optical images. Two image pick-up devices such as TV cameras that have synchronously operated shutters receive the alternate images and convert them to corresponding analog video signals. In some embodiments, the analog signals are converted to a matrix of digital pixel signals that are variously processed and subtracted and converted to signals for driving a TV monitor display and analog storage devices. In other embodiments the signals are processed and subtracted in analog form for display. The high and low energy pulses can follow each other immediately so good registration between subtracted images is obtainable even though the anatomy is in motion. The energy levels of the x-ray pulses are chosen to maximize the difference in attenuation between the anatomical structure which is to be subtracted out and that which remains. <IMAGE>

Title: Load measurement
IPC: B66D1/58
Filed: 1982-03-19
Abstract: A transmitter element, for use in connection with a lifting device to generate an electric signal corresponding to the load being handled comprises a tensile link (1) to which strain gauges are attached. At least one safety link (3) is disposed in parallel with the tensile link (preferably two safety links, one on each side of the tensile link) and is designed to absorb greater loads than the tensile link. In normal operation the tensile link will absorb the entire load acting on the transmitter element. However, the safety link will take over at least a portion of the load acting on the tensile link if the latter is ruptured or abnormally elongated. The transmitter element can be used in a lifting device with a stationary pulley wheel to support one end of the pulley axle, whereas the opposite end is pivotally supported in the frame of the lifting device. <IMAGE>

Title: Battery charging system
IPC: H02J7/14
Filed: 1982-04-01
Abstract: A battery charging system for a vehicle electrical system includes an alternating current generator (10), a voltage regulator (20) and a charging indicator means for indicating faults including faults in the output stage of the regulator. The charging indicator means is provided with a signal generator for detecting the switching state of the power switch (21) of the voltage regulator, a first threshold stage for detecting a minimum value of the generator voltage, and a second threshold stage for detecting a voltage exceeding the desired regulated value by a predetermined value. One input of the first threshold stage is connected to a terminal (D +) of the generator, decoupled from the battery voltage. The input of the second threshold stage is connected to a point (50 or 57) influenced by the battery voltage. Thus the first threshold stage can correctly evaluate the generator voltage, and the second threshold stage can correctly evaluate the state of charge of the battery. The outputs of the second threshold value stage are fed to a logic circuit (Fig. 2) which controls an indicator means (59). <IMAGE>

Patent GB-2110862-A (GB)
Title: Coin handling apparatus
Inventor: EGLISE DAVID
IPC: G07F5/24
Filed: 1982-09-29
Abstract: A microprocessor-controlled coin handling apparatus, for example for a vending machine, has a plurality of change tubes each of which is provided with a single level sensor for determining whether or not the number of coins in the respective tube is greater than a predetermined number. The microprocessor keeps a count of the coins in the tube. When the power is turned on, the count is set to zero if the sensor indicates that the number of coins is less than the predetermined number, and is set to a predetermined "full" number otherwise. The microprocessor increments and decrements the counts as coins are delivered to and dispensed from the change tubes. Whenever the level of coins rises or falls such that the sensor output changes, the coin count is automatically corrected. Also disclosed is a non-volatile memory for storing parameters determining how the coins are handled. Keys are provided for accessing and altering the contents of the memory. Some contents are accessible in a first mode, whereas other contents are inaccessible in this mode, and require a second or third access mode to be entered. At least one location can be altered in a first manner during one of the access modes, and in a second manner only during a different access mode.

Title: Monitoring the breakoff point of a droplet generation system
Inventor: AUER ROBERT E
IPC: G01N33/483
Filed: 1983-02-08
Abstract: In a particle separator for sorting particles suspended in a liquid according to certain characteristics, a change in the droplet breakoff point of a liquid jet stream which is subjected to vibrations is detected. The vibrations, generated by piezo-electric crystal 24, produce, on the surface of the jet stream 16, undulations, the amplitude of which is monitored at a fixed point 21 on the jet stream prior to the breakoff point, producing a signal voltage which is proportional to the amplitude change and which may be used (1) to alert the operator that the point at which the jet stream is breaking up into droplets has changed, (2) to automatically control the intensity of the vibrations for restoring the amplitude of undulation at point 21, or (3) to automatically disable the sorting portion of the apparatus. The detecting means can be a photodiode 44 sensing the light of laser beam 20 scattered by jet stream 16. <IMAGE>

Title: Locks for sliding doors and windows
Inventor: WILLIAMS HARRY MAPLES
IPC: E05B17/00
Filed: 1984-02-03
Abstract: In a lock, used for example on patio doors, in which a slidable headed stud 3 engages with a retainer to lock the door closed, the retainer comprises a resiliently deflectable, preferably spring-loaded, striker plate 2 having a slot 9 with which the stud engages in a locking position. The striker plate is mounted behind a cover 4 with an end part containing the slot overlapping an aperture 5 in the cover. In its released position the stud can enter the aperture beyond the striker plate and can then be slid into the slot to engage its head behind the striker plate and lock the door to its frame. If the stud is entered into the aperture in any position other than the released position it abuts against the striker plate which can deflect against the spring loading. The arrangement avoids damage to the door or frame by the stud, or to the stud, if the door is slammed closed. In another embodiment two studs are provided, each engaging with its own striker plate. <IMAGE>

Patent GB-2147755-A (GB)
Title: Electromagnet control apparatus
Inventor: HAINICH JORG
IPC: H03K17/74
Filed: 1984-07-31
Abstract: An electromagnet control apparatus, for controlling regulating members in a knitting machine for example, has an electromagnet coil 7 connected in series with a capacitor 8. Current to the coil is switched on and off by logical "1" and "0" signals applied to input E. These logic signals are fed through an optocoupler 2,16. At switch on, transistor 6 is rendered conductive so that current flows from a single source UB to the capacitor 8 and the coil 7. A current pulse is developed through the coil 7 to actuate the electromagnet. As the capacitor 8 becomes charged, the current settles to a steady lower value passing through resistor 9 for holding the electromagnet. At switch off, transistor 6 is switched off and transistor 11 is switched on to discharge the capacitor 8 and produce a current pulse through the coil 7 in opposite direction, to destroy remanance in the coil. <IMAGE>
