Patent GB-2253304-A (GB)
Title: Selective growth of InP in semiconductor fabrication
Inventor: KARLICEK ROBERT FRANK
IPC: H01L21/205
Filed: 1992-02-18
Abstract: A process for selectively depositing a series of indium phosphide layers 7 on a substrate comprises using a gas including an indium-organic gas such as an indium trialkyl, a phosphorus source such as phosphine and an organic halide such as trichloroethane. The layers form an isolation region or planarization for an InP laser 1-4. The organic halide decomposes to release halogen at about the same temperature that the indium-organic precursor decomposes. The laser comprises reactive ion etched mesa stripes coated with SiO2 on which, due to the use of the organic halide, layers 7 do not grow. The SiO2 layer is removed before growing InP and InGaAs layers of the laser structure. <IMAGE>

Title: Cooling process and apparatus
Inventor: MORRIS GEORGE JOHN
IPC: F25C1/00
Filed: 1992-05-07
Abstract: Material to be frozen is subjected to a cooling process which involves the application of sound waves, such as ultrasound. The invention has particular application in the frozen food products as margarine, chocolate and ice cream but may also be applied to freeze drying and cryopreservation processes. The material being frozen may also be subjected to a cooling regimen which efficiently removes the latent heat of freezing, for example by increasing the heat extraction rate when the latent heat of freezing is being given up. The invention may permit shorter freezing times and/or improved viability of the frozen or solid product.

Title: Radio telephone handset with earpiece and speaker.
Inventor: GERSHKOVICH IZIDOR
IPC: H04M1/724
Filed: 1993-05-21
Abstract: Figs. 2 and 3 illustrate communications devices (30) that are operable in both a radio dispatch mode and a telephone interconnect mode. To mitigate the problem of a relatively high level audio signal from being unexpected broadcast from an ear-piece of the device (30) when the ear-piece is proximally located with an ear of a user of the device, the communications device (30) is arranged to ensure that, at least during an initial period of operation in either of the two operating modes, audio signals of relatively high level do not originate from the ear-piece, thereby preventing a change in audio power output from the ear-piece that may potentially cause damage to the hearing of a user of the radio communications device. Switching between the two modes and ramping of the speaker output is also described. <IMAGE>

Title: Submarine Propulsion System
Inventor: ADAMS RICHARD
IPC: B63G8/16
Filed: 1995-09-21
Abstract: A submersible vehicle 2 has mounted at the end of arms 6, 7 thrust units 4,5 which act on the arms in the direction of the arrows 15. The arms 6, 7 are connected to the vehicle 2 by a linkage mechanism 14 which is arranged such that when a difference in thrust is applied to the ends of arms 6, 7 the torque on the arms 6, 7 acts via the linkage mechanism 14 to alter the position of the arms 6, 7 and hence the direction of thrust. This can be arranged to cause rotation of the vehicle 2 by applying a differential thrust to the thrust units mounted on the ends of the arms 6, 7 which thrust would otherwise be in a vertical direction to maintain the vehicle 2 in a stable hover position, the vehicle having a negative buoyancy.

Title: Two band 25 channel cordless telephone system
Inventor: APRAEZ MANUEL
IPC: H04M1/72502
Filed: 1996-04-26
Abstract: In a cordless telephone system for operation on the 25 channel bandwidth allocated by the Federal Communications Commission, in which the channels allocated for communication from the base unit to the handset occupy a lower frequency range (43.72Mhz to 44.48Mhz) and an upper frequency range (46.61Mhz to 46.97Mhz) which are relatively widely spaced from one another, improved noise performance is achieved by means of bandswitching in the base unit transmitter output stage and in the front end of the handset receiver. For operation in the lower frequency band, a controller 130 in the handset turns on a transistor Q2 thereby inserting an additional capacitor C3 into a tuned circuit TF1 of the receiver front end, so that this circuit is retuned from the centre frequency of the upper band to the centre frequency of the lower band. Controller 130 also turns on a transistor Q3 to insert an additional capacitor C4 into a local oscillator circuit. A controller (230, Fig.2) in the base unit similarly turns on a transistor (Q202) to insert an additional capacitor (C203) into a tuned circuit of the transmitter output stage for retuning to the centre frequency of the lower band.
