Title: Providing access to passenger vehicles and ventilation arrangement therefor
Inventor: PEPALL GRAHAM EDWIN
IPC: B60J7/08
Filed: 1988-07-19
Abstract: An automobile comprises a body shell, the interior of which is divided into a passenger compartment (5) containing front and rear seats (17 and 18) and a luggage compartment (7), aft of the rear seats (17). Rear doors (15) close doorways which extend from adjacent the rear of the front seats (17) to the rear of the vehicle and which thus provide access to both the luggage compartment (7) and the rear portion of the passenger compartment (5) aft of the front seats (17). A rectangular opening (22) which is formed in the rear part of the roof (8) of the body shell, is provided with two hatch covers (23) which are hinged about axes which run fore and aft. A deflector (24) is mounted to extend above the opening and between the hatch covers (22) when they are open so as to deflect airflow down through the opening (22) when the vehicle is travelling forwards. The deflector (24) lies flush with the covers (23) within the confines of the roof lining when the covers (23) are closed. <IMAGE>

Abstract: A rail trolley having four wheels includes a manually operated brake system having brake means 20 disposed to brake the wheels on one side only of the trolley. Spring means are operative to urge brake pads into braking engagement with the associated wheels 14. On rotation of shaft 32a, 32b about its axis, the pads are moved, via connecting means 34a, 36a; 34b, 36b, against the action of the springs to release the brakes. An operating lever 42 rotating the shaft 32A, 32B to control the brakes can be mounted at either end of the trolley. As illustrated, the trolley is split transversely into two parts 10a, 10b each carrying part of the brake system including a respective one of the two shaft portions 32a, 32b which are connected upon assembly by coupling means. The trolley may alternatively be split longitudinally, with a one-piece shaft extending the full length of the trolley. <IMAGE>
Patent GB-886710-A (GB)
IPC: C10G61/06
Abstract: 886,710. Benzene. BRITISH PETROLEUM CO. Ltd., MOY, J. A. E., and BURBIDGE, B. W. May 16, 1960 [May 28, 1959], No. 18202/59. Class 2 (3). Nitration grade benzene is obtained from feedstocks also containing paraffins and 5 %- 30% by volume of olefins obtained by reforming a petroleum fraction boiling in the range 35‹C.- 200‹C. at 840‹F.-1,075‹F. over a supported chromium oxide catalyst by solvent extraction to obtain an aromatic extract free from paraffins which, freed of solvent, is treated with sulphuric acid and benzene is recovered. The feed may contain other aromatics but preferably contains only benzene, e.g. boiling in the range 60‹C.- 90‹C. The preferred feed is obtained from a catalytic reformate, e.g. using a promoted chromia-alumina catalyst at 840‹F.-1,075‹F., up to 50 p.s.i.g., 0.1-1 vol./vol./hr. in the absence of added or recycled hydrogen. The solvent is suitably diethylene and/or triethylene glycol containing up to 20% by volume of water, the extraction being controlled to obtain an extract free from paraffins and containing less than 5% of olefins. The extract is treated with up to 10% of its weight of sulphuric acid and may be rerun.

Patent GB-2236923-A (GB)
Title: Signal conditioning circuit
Inventor: RAMSAY JAMES
IPC: G01T1/36
Filed: 1989-10-02
Abstract: A circuit for use in gamma-ray spectrometry which conditions the output of a photomultiplier tube for digital signal processing and functions as a multi-channel pulse-height analyser. Current pulses from the photomultiplier are fed into a double integrating amplifier (1 and 2) which provides gain and pulse shaping to give approximately constant width pulses whose amplitudes are proportional to the energies of the pulses from the photomultiplier tube. This signal is buffered (3) to provide a low impedance drive to an analogue-to-digital converter (5) (ADC) which also receives clock signals derived from one of the stages (1 or 2) of the amplifier. In one embodiment the external taps on the internal resistor chain of the ADC (5) are forced to specific voltages by amplifiers (15-19) whose reference inputs are held at a precise voltage by means of a voltage reference diode (20). The tap voltages are trimmed by selection of the amplifier feedback resistors. The effect of forcing these taps to specific voltages is to vary channel width from one channel to the next in order to aid identification of radioactive sources. <IMAGE>

Title: Method and apparatus for waveform digitization
Inventor: POVENMIRE RICHARD M
IPC: G01R13/34
Filed: 1989-11-02
Abstract: An input waveform Vin is shown on a display device 50 such as an oscilloscope as a high density sequence of either horizontal or vertical line segments which track the overall shape of the waveform. This digitization technique includes determining minimum and maximum values of the input waveform and storing 7, 17 these as sets. As these minimum and maximum samples are collected, each sample is compared 12 with a previous minimum and maximum value that had been found during a current line period. The minimum and maximum values for the total line period are stored in a memory. Under processor control 40 these sets of minimum and maximum samples determine the length of a line and are displayed 303 on a visual display device 50 such as an oscilloscope. <IMAGE>

Title: Brushless direct-current motor operating method
Inventor: MEYER HELMUT
IPC: H02P6/15
Filed: 1991-03-18
Abstract: With so-called single-current measurement in the direct-current link of a brushless direct-current motor, there is the problem that current peaks occur in the phase windings during commutation. said current peaks not being detected by single-current measurement in the direct-current link. Consequently, current regulation during commutation is based on an incorrect actual value of the current. The invention proposes a method that, firstly, measures the motor current in low-cost manner by means of single-current measurement at 4 in the direct-current link and, secondly, suppresses the current peaks that occur during commutation. This is achieved in that, in the phase windings, the current buildup is delayed by time period (tv, Fig. 2) in relation to the current decay. <IMAGE>

Title: Television receiver
Inventor: STRACHAN J
IPC: H04N7/167
Filed: 1991-05-24
Abstract: An interface circuit is shown for a television signal receiver which includes decoding means for decoding scrambled or encrypted signals. An input interface circuit supplies the demodulated base-band video signal to the video de-scrambler and an output interface circuit supplies the de-scrambled signal to a video output port. The functions of the interface circuits are very similar in that they both provide, essentially, low pass filtering, the first to remove audio signals above the video base- band and the second to remove spurious signals produced by the de-scrambling process. The low pass filters are designed to provide optimum amplitude response over the video band and the resulting phase delays are compensated by a delay compensating circuit. <IMAGE>
