Patent DE-4319861-A1 (DE)
Title: Battery charger with detection of fully charged condition - computes second deriv. of measured battery voltage after expiry of waiting time preceding acceleration of charging by increase in current.
Inventor: SHINOHARA SHIGERU
IPC: H02J7/00
Filed: 1993-06-16
Abstract: The battery (2) is charged from an AC supply (1) via a PWM invertor (20) between two rectifying and smoothing circuits (10,30). Its voltage is measured by a resistive divider (40) linked to a single-chip microprocessor (50) controlling a current regulator (60) connected between a measuring resistor (3) and the invertor. The pulse-width is responsive also to the microprocessor which sets (4) the initial charging current before the regulator maintains (5) the continuing current at a reference level. A constant-voltage source (70) resets (57) the microprocessor and supplies a state-of-charge indicator (80). USE/ADVANTAGE - Esp. for charging Ni-Cd rechargeable batteries; the number of cells can be established exactly so that charging can be terminated on attainment of full charge.

IPC: A22C13/00
Filed: 1993-06-23
Abstract: A casing for the encasing of foods, especially sausage products, has a textile carrier layer, on which a layer of food-resistant material is arranged. So that a sausage casing impermeable to water and fat, but at the same time also permeable to gas and steam can be produced in a simple way, it is proposed that the textile carrier layer be provided with a dot coating of a hot-melt adhesive, the said dot coating being arranged in a dot grid, at least the interspaces formed between the dots of the grid being covered with a further coating.

Patent DE-4328097-A1 (DE)
Title: Device for measuring the impedance of sensors with a double-feedback phase locked loop
Inventor: BECKER WOLF-JUERGEN PROF DIPL
IPC: G01D5/243
Filed: 1993-08-20
Abstract: In inductive, capacitive and resistive sensors, the signals are usually evaluated by analog means with resonant LC circuits, measuring bridges or by 4-conductor measuring techniques. A frequency-analogous signal evaluation with a double-feedback phase locked loop (PLL), a measuring phase shifter being arranged as low-pass or high-pass filter with the sensor component in one feedback line, offers significant advantages compared with the usual methods. On the one hand, the sensitivity is much higher and, on the other hand, digitisation of the phase locked loop is possible, with the exception of the measuring phase shifter, so that the output signal can be present both in analog form and digitally in series or parallel form.
Patent DE-4331845-A1 (DE)
Title: Tyre pressure warning signal generation method
Inventor: KREFT JOERG DIPL ING
IPC: B60C23/06
Filed: 1993-09-20
Abstract: The warning signal generation method involves feeding the rotational wheel speed signals to a filter (10) for summing storage. The prevailing summation value is evaluated in a computing stage (11), possibly for generating the warning signal. It is ascertained by means of fuzzy logic (5, 6, 7) in accordance with plausibility principles whether changes in the rotational speed signals are to be associated with acceleration of the vehicle or a tyre defect.In the first case, the signal path to the filter (10) is interrupted, or the signals are subjected to attenuation, so that they are weighted to a lesser extent. However, the summation value previously ascertained in this stage (10) is not erased, so that if need be, a warning signal is generated very rapidly after a travelling operating state with acceleration has ended.

Patent DE-4407627-A1 (DE)
IPC: A63B55/60
Filed: 1994-03-08
Abstract: A motorised three-wheeled golf trolley has two driven side wheels (2, 3) and a rear wheel (4) on a foldable support leg (5, figure 1). The two side wheels are retractable into a storage position so that the golf trolley takes up approximately the same space as its non-motorised counterparts. This is achieved without needing to dismantle the golf trolley. Each wheel is slidably mounted on a drive shaft (20, 21) which has two shaft portions (22, 24; 24, 25) connected by a swivel joint (26, 27). In the operating position, figure 2, the wheels are retained by latches (30, 31) on the wheel hubs (28, 29) which cooperate with slots (32, 33) in the outer shaft portions (23, 25) and the swivel joints are covered by the hubs. To collapse the trolley, figure 3, the wheels (2, 3) are moved inwardly so that the shafts portions (23, 25) are folded upwardly. <IMAGE>

Patent DE-4418216-A1 (DE)
Title: Positioning patients during radiological diagnosis or radiation therapy
Inventor: ROECKSEISEN ARMIN DR
IPC: A61N5/10
Filed: 1994-05-25
Abstract: A process for positioning a patient on an adjustable underlying table for radiological diagnosis or radiation treatment uses one, or preferably three, laser outputs to transmit beams along the length and or across the patient;s body. These should intersect at the position on the patient's body required for the isocentre, which may be pre-marked. The underlay is adjusted along one or three orthogonal axes until the markings are in this required relationship with the laser beams. Three receptor pads, fixed to the patient's skin by means of surgical plasters, reflect the laser beams back to sensors which control an evaluation and steering device. This produces a signal when the pads have attained the chosen distance from the isocentre of the radiation equipment and positioning is complete.

Patent DE-4421773-A1 (DE)
Title: Gas spring as lifting aid for vehicle tailgate
Inventor: FREITAG HERBERT
IPC: F16F9/02
Filed: 1994-06-22
Abstract: The gas spring (G) which supports a lift up door, or tailgate, is clad with an electric heating element (36) covered by a thermal insulating jacket (38). The electric heater maintains the temperature of the gas volume (18) to provide a constant support for the door over a wide range of external temperatures. The heating system is linked to a key operated lock (32) and rapidly heats the gas spring to the operating temperature after the vehicle is started. The gas spring is fitted with an internal temperature sensor (52) and an internal pressure sensor (54) to monitor the state of the spring. A pressure sensor (56) in the spring mounting monitors the operation of the spring. The gas spring heater is also linked to the vehicle electric system to operate when the vehicle is driven. The gas spring pressure is lower than required for normal temperatures and requires some heating for normal temperatures. This provides a control for higher than normal temperatures as well as for low temperatures.

Abstract: Adjoining the nipple (20) where it is pressed into the hose (10) is a projecting part to give a pull-proof join where it drives onto the rear shoulder (13a) of the cap-nut. The projecting part forms a collar (22) and the reduced-diameter head part (20) of the nipple seats and is sealed by a slide ring (30). This ring is fronted by a sealing ring (32) as against the rear of the ring (30) which bears non-rotatably on a front shoulder (41a) of the cap-nut once this is screwed tight. The press join between nipple and plastics hose (10) includes an external sheet metal sleeve (12) complete with locking collar (12a) to bear against a cap-nut shoulder. The curvature of an internal metal sheet sleeve (13) between hose and metal sleeve (11) is pressed into the spiral sleeve turns (11) and the sleeve (13) also has its own locking collar (13a). An O-ring (32a) in a grooved part of the nipple seals this off from the sliding surface (32) of the ring (30).
