Title: Coding system for recording digital audio
Inventor: DIETERICH CHARLES BENJAMIN
IPC: G11B20/00
Filed: 1982-10-12
Abstract: Apparatus is provided for recording and recovering a digital manifestation of an analog signal. The digitized analog signal is time- compressed into successive segments of predetermined duration. Synchronizing signals are interspersed between successive segments. The digitized, time-compressed signal is encoded with an error correcting code. Prescribed segments are replaced by auxiliary digital information, such as frame identification signals. Recording apparatus comprises: a digital signal source (10, 11, 12); means (13) for time-compressing the digital signal; means (14) for error- correcting-encoding the digital signal; and means (17) for multiplexing the encoded digital signal, synchronizing signals, and auxiliary digital information. Playback apparatus comprises: a digital signal detector (31, 32, 40); an error correcting decoder (42) which treats the auxiliary information as a burst error; and means (44, 45) for converting the decoded digital signal to analog. <IMAGE>

Title: A spreading apparatus to be placed on a vehicle
Inventor: PETERSEN JENS
IPC: E01C19/20
Filed: 1982-11-11
Abstract: A spreading apparatus to be placed on a vehicle and comprising a container, from which the spreading material can be distributed through a dosing device, and velocity sensing driving wheel (3) placed at the rear end of the vehicle. The driving wheel may be lowered into contact with the roadway and is adapted to drive the dosing device and possibly also a spreading disc through an energy transferring device. The energy transferring device is provided by means of a hydraulic wheel pump (4) coupled to the wheel (3), said hydraulic wheel pump feeding pressurized liquid through a liquid conduit to one or more hydraulic motors (11) driving a plurality of stirrer and delivery rolls. The pressurized liquid is also fed to a piston (12) in a cylinder, which when the pressure in the conduit has been reduced to a predetermined value due to an empty material container, or as a consequence of the spreading being decoupled, reduces the pressure of the wheel (3) against the roadway. <IMAGE>
Patent GB-2110432-A (GB)
Title: Vegetation cutters
Inventor: MASSEY GRAHAM ALBERT
IPC: A01D69/02
Filed: 1982-11-15
Abstract: A vegetation cutter, e.g. an air- cushion supported lawn mower, driven by an electric motor such as a commutator motor is fitted with an electronic motor control unit effective to limit the maximum no-load speed of the motor, to stabilise motor speed over a predetermined range of motor loads, and preferably to enable the motor to rotate at another lower speed which is also constant over a predetermined range of motor loads. The lower speed produces a reduction in the cutting height of the mower. The speed of the motor is sensed by a Hall effect device, where output is fed to a frequency-to-voltage converter and ramp generator connected in the trigger circuit of a triac. The desired speed is manually set.

Patent GB-2120327-A (GB)
Title: Automatic release mechanism
Inventor: RICHARDS BERNARD OWEN
IPC: B63B23/58
Filed: 1983-05-06
Abstract: This invention relates to a hydraulic means to release a safety catch, and is particularly suitable for use on lifeboats carried on ships. The hydraulic means suitably has a hydraulic master cylinder 8 actuable by hydrostatic force and a hydraulic slave cylinder 10 responsive to the actuation of the master cylinder and connected to the safety catch whereby actuation of the slave cylinder by the master cylinder releases the safety catch. The actuation of the master cylinder by hydrostatic force is achieved by means of a diaphragm 3 or a float 6 or a combination thereof. One of the principal features of the present invention is that the use of a hydraulic means enables a significant mechanical advantage to be achieved by varying the relative diameters of the master and slave cylinders. <IMAGE>

Title: Apparatus for transmitting and receiving infrared signals
Inventor: BAHRING HORST
IPC: H04B10/114
Filed: 1983-06-14
Abstract: The invention relates to an apparatus for transmitting and receiving infrared signals. In the region of the focal point of a concave mirror there is placed a comparatively small infrared sensitive area (9) of an infrared sensitive diode. For the purpose of adjusting said infrared sensitive area its mounting (8) is made longitudinally movable by about 2 to 3 cm along the axis of said concave minor. Several infrared-transmitter-diodes are placed near the edge of the opening of the concave mirror their axes of radiation being generally parallel to the axis of said mirror. Comparatively weak signals incident in the direction of the axes of the mirror can be received by this arrangement. Disturbances by other infrared transmitters, e.g. at transmissions in large workshops by arcs of welding equipment, by lighting up signal lamps, furnaces and incident sun light can be practically fully avoided. <IMAGE>

Patent GB-2161293-A (GB)
Title: Sequence controller
Inventor: GEORGE MARTIN CLEMENT JOHN
IPC: F24D12/02
Filed: 1984-07-03
Abstract: The invention is concerned with the problem of time-lag arising in heating systems using a plurality of boilers (10, 12, 14) which are successively switched in or out according to load requirements, and provides that during times of increasing load when an additional boiler is required, that boiler is initially switched in at a low setting and at the same time a previously switched in boiler is reduced to low setting. This may reduce unnecessary switching in and out particularly when the structure of the previously switched in boiler is not at normal operating temperature at the time when the next boiler is called in. <IMAGE>

Title: Vacuum head for transporting sheet material
Inventor: MULHOLLAND P B
IPC: B65H5/08
Filed: 1985-08-23
Abstract: This invention relates to a vacuum head for the transportation of sheet material 11, such as a sheet made from pastry, which tends to have fissures or tear easily. The head which is used preferably in a pasty making machine comprises a number of compartments 2, 8 separated by airtight walls and a material contacting face 3 having apertures 5. The head is also provided with a cutting edge 6 and the compartments are connected to a source of suction and air pressure. In operation the head cuts out a portion of the material from a continuous sheet made on the machine whilst suction is applied to the head. The latter then transports the portion of the material to a station in the machine where the portion is released by the head by replacing suction with air pressure. The portion is then processed further into a pasty, by the provision of a filling and sealing of the edges of the portion preferably with preheated dies. <IMAGE>

Filed: 1985-08-29
Abstract: A buffered thickening agent, for use in cleansing lotions or in topically applied medicaments or cosmetics, comprises a naturally occurring gum, such as a Xanthan gum, and an orthophosphate buffer. The buffer thus acts to increase the viscosity of the gum in use so that higher ionic concentrations can be tolerated without destabilisation of the emulsion when the buffered thickening agent is formed into a lotion. Preferably the buffered agent constitutes 0.5% to 2% by weight of an oil-in-water protective cleansing lotion which may also comprise 10% to 20% by weight of petrolatum.
