Title: Burglar alarm network
Inventor: ZEE LESLIE LOONG
IPC: G08B27/00
Filed: 1993-07-28
Abstract: The network consists of one host house and supporting houses around it. When the alarm of the host house is triggered off and the sirens and the flashing lights are activated, a signal will be sent off to activate the receiver in the supporting houses thus to prompt the supporters to act quickly to do the following:     A. Inform the police, and   B. Watch the host house with special attention.   A plurality of individual networks (one host house and its supporting houses) can be combined to form a large scale network to fight burglar crime more effectively. All member houses of the network are protecting themselves by protecting the other members rather than depending upon a commercial firm's efficiency.

Title: Pallets for use in load handling.
Inventor: GILMOUR JOHN
IPC: B65D19/00
Filed: 1993-08-13
Abstract: A pallet comprises a rectangular sheet aluminium panel 10 of corrugated configuration and having in plan view sides parallel with the corrugations and stiffening bars 15 attached one to each end of the panel and disposed substantially flush with one face of the panel 10 and extending from side-to-side of the panel. The corrugated configuration provides for accommodation of lifting forks B for handling, and the stiffening bars 15 improve the loading capacity of the panel. The ends of the panel 10 are configured to lie in respective planes which are mutually convergent towards the other face of the panel so enabling the pellet to be stacked with other pellets of the same construction, when not in use, easily and without jamming together. Aluminium or aluminium alloy hollow section bars are used for the stiffening bars 15. On the underside of the panel 10 are welded stiffeners 18 in the form of half-round stock material (see figure 2, not shown). In a modification the stiffeners 18 are formed by indentations in the panel 10. <IMAGE>

Patent GB-2271869-A (GB)
Title: A hydrostatic drive system
Inventor: KROPP WALTER
IPC: E02F9/22
Filed: 1993-10-11
Abstract: A hydrostatic drive system, particularly for an excavator, comprises a required-flow regulated pump and a plurality of consumers (6, 8) actuated by respective directional control valves (5, 7) which perform a throttling function in intermediate positions. For load-independent delivered flow allocation, when consumers (6, 8) are simultaneously actuated, each valve (5, 7) is assigned an auxiliary valve (9, 10) which is controlled by a signal difference formed from a load pressure signal and a delivered pressure signal. The load pressure signal is derived from the highest of the load pressures occurring downstream of the valves (5, 7), and the delivered pressure signal is derived from the pressure upstream of the valves (5, 7). To limit the driving force and driving moment of at least one of the consumers, the signal difference across the valve (9) of that consumer (6) is influenced by the output signal of a control valve (20) so as to limit the flow through the valve (9). For this purpose the valve (9) has a control surface which is operative in the closing direction and which is selectively exposed to the highest load pressure or pump pressure. The control valve (20) is acted upon by a preferably adjustable spring and via a line (21), by a variable control signal to urge it towards an operating position which connects the highest load pressure from a line (12) to the output, and it is acted upon by an opposing signal derived from the individual load pressure of the consumer (6). An undersired rise in this load pressure moves the valve (20) to an operating position which connects the pump pressure from a line (4a) to the output. <IMAGE>

Title: Toaster
Inventor: YEUNG MIU CHOY
IPC: A47J37/08
Filed: 1993-12-16
Abstract: A toaster (10) has a casing (11), a cavity (12) in the casing, a heating element on opposite sides of the cavity, a cartridge (15) in the cavity for supporting a slice of bread to be toasted by the heating element, said cartridge being movable between an upper position in which a said slice is partially extending outside the cavity (12) and a lower position in which the slice is wholly within the cavity and being biassed towards its upper position by a spring (29), a timer to determine the toasting time of the slice, and holding means (23) to hold the cartridge against moving upwards into the upper position before and after completion of the bread toasting, the means (23) being manually releasable. The slice is thus held within the toaster at completion of toasting and allows crispness to be maintained for longer periods compared to conventional ejection. <IMAGE>
Patent GB-938656-A (GB)
Abstract: 938,656. Phase measurement. LOSENHAUSENWERK DUSSELDORFER MASCHINENBAU A.G. Feb. 2, 1960 [Feb. 11, 1959], No. 3606/60. Class 37. [Also in Group XL (b)] In a balancing machine the phase of the output from transducers 10, 11 detecting variation of pressure on the mountings for the rotating body is compared with a reference signal generated photo-electrically by scanning angularly spaced marks on the body. The transducers 10, 11 feed voltage dividers 15, 16, connected in opposition and the signal obtained is amplified and fed to parallel bi-stable switch circuits 18, 19. Photo-transistor 14 forms a voltage divider with resistor 20 to give a reference signal input in pulse form. The pulses are differentiated and fed through rectifier 22 to the cathodes of bi-stable switch circuit 23 comprising valves 24, 25. The square-wave output from this switch is prevented from locking in out of phase by selecting the pulses caused by one mark longer than the rest and applying them to the grid of valve 24. The waveform from circuit 23, which is normally of double the rotation frequency is differentiated and the positive and negative pulses separated and fed respectively to the grid of stage 19 and the cathode of stage 18. The stages 18 and 19 thus switch over, with a phase shift of 90 degrees between them every 180 degrees of body rotation and voltages tapped off one of the anode resistors of each stage and indicated at 32, 33 correspond to two components of the direction of unbalance with reference to orthogonal axes. The switches 18, 19 may alternatively be energized by D.C. to produce square waveforms applied respectively together with the signal voltage to two wattmeters or phase-sensitive rectifiers to give similar outputs.

IPC: B41J2/025
Filed: 1995-08-09
Abstract: An apparatus and method for producing a stream of ink drops in a continuous ink jet printer (20) having a maximum allowable number of fast satellite drops. An ink, which may be a hot-melt in its liquid phase, is pressurized for continuous flow to a nozzle (26) and a rectangular or triangular waveform is generated at a fixed frequency. The waveform is applied to a transducer (30) coupled to the nozzle (26) such that nozzle vibrates and the ink flow is perturbed and discharged from the nozzle as primary drops with satellite drops formed therewith. The harmonic content of the rectangular or triangular waveform is adjusted until the desired number of fast satellite drops suitable for desired image formation are formed in the stream of primary drops. In a preferred embodiment, the desired number of fast satellites is a maximum of three.
