Patent GB-2040865-A (GB)
Title: Bale loading and transporting machine
IPC: B62D53/06
Filed: 1979-12-31
Abstract: A machine for the loading, transporting and unloading cylindrical bales of forage, has a base frame (A) forming a wheeled trailer connectable behind a tractor. An extendable arm (15,16) is pivotally mounted on one side of the base frame (A), the arm (15,16) being displaceable hydraulically to lie close to the ground and having forwardly extending rods (17,18) for engaging a round bale to be loaded. The spacing between the rods (17, 18) is variable to enable a variety of sizes of bales to be accommodated. When a bale has been positioned between the rods (17,18), the arm (15, 16) is displaced to a substantially vertical position thereby loading the bale on the trailer. The trailer also has a displaceable frame (B) mounted on the base frame (A) and having endless chains (10) for transporting a bale, when loaded, towards the rear of the trailer to enable further bales to be loaded. To secure the bales during transportation a plurality of lateral displaceable tines (25) are provided. The bales may be unloaded individually or as a vertical stack, in which latter case frame (B) is hydraulically displaced on said base frame (A) into a vertical position and then the tines (25) release the stacked bales. <IMAGE>

Title: Signal Lamp Emitting Coloured Light
IPC: F21V9/08
Filed: 1980-03-05
Abstract: A signal lamp, for example for a vehicle, emitting coloured light has, in front of an incandescent lamp (3), a colour filter (7) with a spherical-cap-shaped central region adjacent the incandescent lamp. An optical disc (10) acting as a collecting lens and a cover disc (1) acting as a dispersion lens are disposed in succession in front of the colour filter. To minimise apparent false signals from external light escaping after reflection through the colour filter, the optical disc has an outwardly domed or conical central region into which the colour filter projects little if at all, and refractive prism elements (14) of the collecting lens are formed on the outer face of the domed region. The optical disc has at least one plane surface (11) provided with total-reflection prism elements (13) on its rear face. <IMAGE>
Patent GB-2052915-A (GB)
Title: A system for the television scanning of films
IPC: H04N3/38
Filed: 1980-05-28
Abstract: A system for the television scanning of films in which the film is continuously moved and is scanned without interlacing comprises a frame store into which respective signals belonging to a scanned line are read at an address characterising the position of the line within the film frame and from which are read out once again in accordance with the television standard. In so doing, the respective address is formed either by counting pulses derived from the line and frame frequency of the television standard (coupled operation) or by counting pulses derived from the film speed (uncoupled operation). To prevent cut edges with studio asynchronous film speeds below 50 frames per second, during the reading in of one film frame into one half frame store, the other half frame store is simultaneously completely and frequently read out until the reading in of the one film frame has finished. To prevent cut edges during the scanning of 35 mm Cinemascope films, the frame store is divided into six storage regions each 2 of which belong to one half frame store and are driven alternately from film frame to film frame whereas the 3rd storage region of each half frame store is driven during each film frame. <IMAGE>
Patent GB-2077773-A (GB)
Title: Washing Machine
IPC: D06F23/04
Filed: 1980-06-04
Abstract: An automatic washing machine of the fresh-water, vertical-axis type has a dynamic system which includes a single perforate wash basket 32 arranged to be driven continuously such that its central axis moves in an orbital path about another axis, rotation of the basket 32 about its central axis being restrained. Water is introduced into the basket 32, through a hollow annular fill ring 132 on the tub 36 and through a spout 30 to wash detergent from a cup 48, during orbital motion and that motion is effective to induce a continuous motion of the fabric article load for washing the load. Following washing, preferably the basket's central axis is aligned with the axis about which it was orbiting and is rotated about this axis to centrifugally remove water from the fabric load. The basket may be contoured to enhance toroidal and annular movement of the fabric load, e.g. by the provision of curved vanes 39, rings 53, ribs 58 and vanes 60. The machine transmission has an input shaft 203 driven by a reversible electric motor 20, and an output shaft 78 connected to the basket, the transmission having drive elements 74 for interconnecting the output shaft and the input shaft. The drive elements include eccentric drive members operative to shift the axis of the output shaft laterally from the axis of the input shaft when the input shaft is rotated in one direction, thereby driving the output shaft in an orbital path about the axis of the input shaft, and operative to substantially align the axes of the input and output shafts when the input shaft is rotated in the other direction, thereby rotating the output shaft. A one-way clutch and a disc brake assembly, including an off- center coupling, cooperate with the drive elements to restrain the basket from rotating when in the orbit mode or when the motor is deenergized, and to rotationally drive the basket when in the water extraction mode. <IMAGE>

Patent GB-2083745-A (GB)
Title: Controlled temperature hair dryer
IPC: A45D20/12
Filed: 1980-09-18
Abstract: A hair dryer is provided wherein the temperature of the air stream is automatically controlled by the temperature of the hair being dried. The dryer includes a primary air inlet 16, a fan 17 for blowing inlet air out of the dryer, and a heater 20 by which the blown air is heated before it is directed against a user's hair. The dryer also includes a feedback air duct 25 and a thermistor 26 positioned in the duct to sense the temperature of the air being reflected off the user's hair as it is dried. The thermistor changes resistance in accordance with the temperature of the reflected air. The change in resistance is sensed by an integrated circuit zero crossing switch that electronically signals a thyristor causing the thyristor either to switch off or proportionally reduce the power to the heater, thereby reducing the amount of heat energy input in the blown air. Consequently, the temperature of the air being blown against the user's hair is continuously monitored as the hair dries to avoid overheating of the hair and scalp. <IMAGE>

Patent GB-2097566-A (GB)
Title: Well logging
IPC: E21B47/12
Filed: 1979-09-18
Abstract: The accuracy of well logging data transmitted from a downhole location to the surface of the earth is verified by generating the data at the downhole location, storing the data in a subsurface assembly in the well, transmitting signals corresponding to the data to the surface through a first transmission system while keeping the data stored in the subsurface assembly, and recording the signals transmitted to the surface through the first transmission system. Thereafter, the subsurface assembly is transferred to the surface, and signals corresponding to the stored data are transmitted through a second transmission system from the assembly to an electronic processing system. The signals transmitted through the second transmission system are then compared with the signals transmitted through the first system. To increase the effective transmission rate of data from the downhole location to the surface, a first set of signals corresponding to the magnitude of a downhole condition as a function of time during a discrete time interval are generated and transmitted through a first transmission system to computer means at the downhole location. The first set of signals are analyzed in the computer to determine properties of the function selected from the group consisting of mean value, positive and negative peak values, standard deviation value, and fundamental and harmonic frequencies and amplitudes. A second set of signals corresponding to the selected values are generated and transmitted to the surface through a second transmission system.
