Title: Apparatus for cracking a melon seed
Inventor: WU HANS
IPC: A47J43/26
Filed: 1989-04-12
Abstract: An apparatus for cracking the hull of a melon seed includes a flat plate (31) and a pair of cracking members (20) pivoted to the flat plate (31), each member (20) having a handle portion (22). A protrusion (33) projects from the surface of plate (31) at which the cracking members (20) are located. Members (20) have clamping edges (211) which face each other and clamp the tapered end of the melon seed to be cracked when the cracking members (20) are moved toward each other, while the round end of the melon seed abuts the protrusion (33). The two spring members (24) urge the cracking members (20) away from each other to a position at which the melon seed may be released.

Title: Weathershield
Inventor: GILCHRIST DAVID
IPC: B60J1/20
Filed: 1990-03-24
Abstract: A weathershield comprises a consertina folded board which, when opened, covens a vehicle windscreen (inside or out) and also folds to fit the rear window. Its design enables the shield to fit varying sizes of windscreens and rear windows in height and width. In summer when the shield is opened and placed inside the vehicle windscreen, it reflects the sun's ultra violet rays and therefore keeps the inside of the vehicle cool. In the winter when the shield is opened and placed outside the vehicle windscreen, all ice, frost and snow lays onto the shield and does not come into contact with the windscreen. When shaken all deposits will fall away. The shield can also be reversed and folded in such a way that it fits into the rear window. Once in position it displays a luminous warning sign for those vehicles which have broken down. <IMAGE>

Title: Clutch operating system including signal transmitter
Inventor: BOSS FRANZ
IPC: F16D48/06
Filed: 1990-05-15
Abstract: In a clutch operating system, a signal transmitter device (1) is connected via pressure medium in a pressure-medium circuit (5) between a clutch pedal (3) with the master piston unit (31) and the slave piston unit (41) of the clutch (4). This signal transmitter device generates a pressure signal (11) when, after a gear-change, a gear is again engaged in the gearbox causing an electromagnet (15) to be energised. This signal is transmitted via the pressure-medium circuit (5) to the master piston (32) and thus to the clutch pedal (3) as a tactile signal. To match this signal to the driver's requirements, an adjusting device (13), with which the signal strength can be regulated, is fitted to a pressure piston (12). The pressure piston may be connected to a larger piston (Fig 2) actuated pneumatically from an air reservior via a pressure reducing valve and under the control of a solenoid valve. <IMAGE>

Title: Sheet sorting apparatus
Inventor: CHUNG JAE HEON
IPC: B65H39/11
Filed: 1991-10-02
Abstract: In apparatus for sorting sheets into movable trays (not shown), the trays having pins (not shown) which are moved along slots 20 (one shown in figure 3), wheels 40 are provided for propelling the pins along a central kinked slot section. Each wheel includes three 120 DEG - spaced channels 44 for receiving end portions of successive pins and moving them along the slots as the wheel rotates about axle 31. Between each adjacent pair of channels is an insert 46 and an insert 47. As the wheel rotates, cams 32 determine the axial positions of the inserts 46, 47 on stubs 43. This determines which of two axially-spaced outer curved surfaces of each insert contacts the pins for guiding same at entry into and exit from the channels. The effective guidance surface geometry is thus changed to match requirements which differ according to whether pin movement is up or down the slots and whether the pin is entering or leaving a channel. <IMAGE>

Title: Sigma-delta converters
Inventor: PEARCE TIMOTHY HALCOMBE BROOK
IPC: H03M3/02
Filed: 1992-04-10
Abstract: In order to improve the signal-to-noise ratio of a known sigma-delta analogue-to-digital converter A, the input to the loop filters 3, 4 (which can be regarded as an error signal between the analogue input and, ignoring imperfections in the digital-to-analogue converter 8, the analogue equivalent of the digital output), is filtered, 10, amplified, 11, and converted to a digital signal in a second sigma-delta converter B. This digital signal is combined with the digital output of the analogue- to-digital converter A to produce an output of the two stage converter with improved signal-to-noise ratio. Phase and amplitude errors introduced before the signals are recombined are corrected for by an equalisation network which is calibrated at regular intervals by means of a test generator 18. The same technique can be employed to produce a digital-to-analogue converter, and a digital modulator, with improved signal-to-noise ratio. <IMAGE>
Patent GB-2254946-A (GB)
Title: Alarm system
Inventor: AMLANI MANHER
IPC: G08B29/04
Filed: 1992-04-16
Abstract: An alarm signal assembly includes alarm units 12 each having a signal device e.g. an electrical sounder (12) and a holder (2), Fig 1 (not shown). The sounders are connected in series in a circuit 38, 38. Each includes disruption means 18 eg a microswitch such that separating a sounder from its holder detectably alters the circuit characteristics but without preventing actuation of the sounders. Thus a sounder may have two conduction paths, one containing a diode 28 and the other containing a microswitch 18. Separation from the holder causes the microswitch to break a conduction path. The other is still available, and the diode characteristic is detectable by the circuit. The circuit may have two branches 32, 34 which are maintained at different polarities, and one of which provides the pairs of conduction paths. Actuation of the sounders is effected by reversing the polarities, which can be done even if one or more microswitches 18 has broken a respective path. <IMAGE>
