Patent GB-898961-A (GB)
Abstract: 898,961. Jet propulsion plant. GENERAL ELECTRIC CO. May 12, 1959 [June 5, 1958 (2)], No. 16228/59. Class 110 (3). A supersonic jet propulsion power plant has a jet propulsion engine 12 in a duct or casing 10, the casing having an upstream section of convergent-divergent configuration with an air inlet of fixed capture area and a downstream section of convergent-divergent configuration with a fixed exit area nozzle, the jet propulsion engine 12 being positioned to provide a by-pass duct 14 and wherein variable means 20, 22, 25 are provided in the inlet and outlet sections to direct air selectively through the power plant and by-pass duct simultaneously or through the power plant only except for some air leakage through the by-pass duct. For supersonic flight at the design speed, the inlet and outlet ducts are set as shown by solid lines in Fig. 1 and only a small amount of the air taken in is by-passed around the power plant, if required for cooling purposes. When the operating speed is lower than the design speed, the inlet flaps 20, 22 are moved to the positions indicated by dotted lines as are the outlet flaps 25. Instead of hinged flaps sliding flaps may be used. The power plant in Fig. 1 has a variable area nozzle 19 or the exit nozzle may be fixed and the throat formed by an adjustable flap 25 (Fig. 5).

Inventor: PRITCHARD JOSEPH
IPC: E06B7/14
Filed: 1990-03-30
Abstract: A drainage device comprises a channel section member (10) and two stop-ends (12) of corresponding cross-section. An assembly of the member (10) and stop-ends (12) is fixed to the bottom interior edge of a window pane (36). The member (10) serves to collect condensation which may form on, and run off, the interior of the window pane (36). The stop-ends (12) each have a drainage pipe (26) through which collected water is drained e.g. via flexible PVC tubing (33) to the outside of the window frame. To cope with the drainage of condensation from wide windows a bridging member with its own drainage pipe can be spliced into the middle of the member (10). <IMAGE>

Title: Vehicle control system
Inventor: MAKINO NOBUHIKO
IPC: B60T8/66
Filed: 1990-05-16
Abstract: A plurality of speed sensors 5-8 sense rotational speeds of respective vehicle wheels and the speeds of the vehicle wheels are calculated in a microcomputer 36 on the basis of detection signals of the speed sensors. A judgment is made as to whether or not a vehicle wheel having a small tire is present in the vehicle wheels on the basis of the calculated speeds of the vehicle wheels. In cases where a vehicle wheel having a small tire is judged to be absent, a control quantity is calculated by use of all the detection signals of the speed sensors and fed to drive circuits 46-49 e.g. for controlling braking. In cases where a vehicle wheel having a small tire is judged to be present, the control quantity is calculated by use of the detection signals of the speed sensors except the detection signal of the speed sensor of the vehicle wheel having the small tire. <IMAGE>

Title: Balancing method and product
Inventor: EHRICH FREDRIC FRANKLIN
IPC: F16F15/32
Filed: 1990-06-29
Abstract: A low-speed balancing method is provided for balancing a rotor to introduce balance corrections, eg by removing material from lands 56, 58, 74, for reducing unbalance due to operation of the rotor at or near critical speeds without actually balancing the rotor at such critical speeds. The method is applicable for balancing a rotor in three, four or more correction planes 52, 54, 72 by utilizing combinations of generic unbalance distributions of the rotor and predetermined mode shapes of the rotor at critical speeds. A simple method is presented which allows an operator using a low-speed balancing machine to determine measured corrections applicable to two plane of the rotor and then the operator effects at least a third correction to the rotor which is proportional to the first and second measured corrections and the unbalance/mode shape combustion. The operator then repeats the low-speed balancing sequence to determine final corrections at the first and second planes, which are then made for finally balancing the rotor. <IMAGE>

Title: Synchronisation of digital audio signals
Inventor: FLETCHER WILLIAM HAROLD
IPC: G06F5/12
Filed: 1991-03-25
Abstract: A digital audio signal which is subject to sample-to-sample jitter is synchronised with local reference pulses (READ) by the use of a read-write buffer memory (12). Timing pulses (80) are associated with the input samples. The input samples are applied through a one-sample latch store (36) to the main memory, and the timing pulses are applied by switches (66,68) either directly or a short delay (38) to the write control input of the main memory. A phase comparator (24; Fig. 3) detects sample-by-sample when the write pulses are near to the read pulses and causes the switches to change state in response thereto, and they retain their changed state until a danger of potential read-write contention is again detected when they revert to their original state. <IMAGE>

Inventor: HIROKI ITO
IPC: C23C14/22
Filed: 1991-12-13
Abstract: A film forming apparatus which utilizes cluster ion beam deposition to form thin films on a substrate. In one embodiment as illustrated in Fig 1, the electrons which ionize the vapor clusters are generated by a cathode 22 which is located inside the corresponding anode 23. The position of the anode avoids electrons being captured by the electron- drawing electrode which occurs in prior art apparatus. The cathode serves not only as a source of electrons but also as a means for heating the crucible 3 containing the substance to be deposited. An acceleration device 25 for accelerating ionized clusters towards the substrate comprises an acceleration electrode 26, an attraction electrode 27 having a negative potential with respect to the acceleration electrode and a control electrode 28 having a potential intermediate between those of said acceleration electrode and said attraction electrode. A magnetic field may be applied to the field of electrons emitted by the ionization device. In another embodiment (Fig 3), an electron emitter 43 located at a position remote from the vapor flow in the apparatus is utilized as the source of electrons to form the ionized clusters. The material deposited may be aluminium, titanium, gold, copper, silica, alumina, titania or superconductive barium- yttrium- copper oxides. <IMAGE>

Title: Locating device
Inventor: KIRK ALAN WILLIAM
IPC: B63B22/00
Filed: 1992-04-27
Abstract: Deck cargo is often lost at sea, either by breaking free from its stowage lines and falling overboard or as the result of some accident such as a collision, and can cause serious problems, not only because of the expense involved but also because it may result in damage both to the environment (it may be, or contain, toxic materials) and to subsequently passing shipping (it can be a navigation hazard, or it may result, say, in torn or damaged fishing nets). The invention proposes a simple and inexpensive way of locating lost cargoes, namely a marker buoy (22) that is detachably secured to a support (14) mounted on and carried by the cargo (10), and is releasable therefrom (when the cargo is lost overboard) to float to and on the surface while remaining tethered (by line 23) so as to mark the position of the cargo.

Inventor: ROSS VICTOR E
IPC: B03B5/62
Filed: 1992-08-03
Abstract: A particulate mass is separated into different classes according to the oleophilicity of the particles. This is achieved by pretreating the particles in a manner to selectively render one class of particles, e.g. diamonds, more hydrophobic (e.g. using an oily component) than another class of particles and introducing the treated particles into a body of aqueous froth (37). The particles are recovered in fractions according to the rate at which the particles sink in the froth (37). The froth upper surface is restrained by a screen deck comprising flexible parallel rods (38) that are individually transversely flexed (48, 48). <IMAGE>
