Patent GB-2030415-A (GB)
Title: Focus detection device
IPC: G02B7/36
Filed: 1979-08-10
Abstract: A focus detection device for a photographic camera and of the contrast-sensing type includes a photoelectric element (15) of the self- scanning type driven by a driver circuit (16). The element produces for each scanning cycle a train of time- discontinuous pulses which are amplified (17) and applied alternately to first and second sample holding circuits (18, 19). A difference amplifier (20) provides a signal representing the difference between successive pairs of adjacent pulses in the pulse train. The absolute value (21) of the difference signal is taken, and its peak for each scanning cycle is detected (22). This peak will take a maximum value at the in-focus position. High spatial frequency components are not lost by filtering, and the need for differentiation is avoided, while the accumulation effect of the self- scanning element is employed to advantage. <IMAGE>

Title: Electric generators for waterborne craft
IPC: B63H23/24
Filed: 1979-09-13
Abstract: An electric generator for use on waterborne craft, comprises a stator (10) preferably constituting the magnet and a rotor (11) preferably constituting the coils, a sleeve member (13) carrying aerofoil blades (15) and detachably keyed to the rotor, and a nose member (16) permitting attachment at eye (17) of a torque line for driving the rotor without requiring detachment of the bladed member (12). The rotor (11) can therefore be driven by either, or both, of the blades (15) and the torque line. The torque line is connected either to the craft's propeller, Figure 4 (not shown), or to a screw that is trailed behind the craft, Figures 2, 3 (not shown). <IMAGE>

Title: Pressurization System
IPC: B66F11/04
Filed: 1979-10-05
Abstract: A remotely actuated, battery- powered, auxiliary pressurizing system for hydraulically actuated lift arm devices (HL) is driven independently of the principal power source of a vehicle (V) on which the hydraulic lift arm device may be mounted but utilizes the same hydraulic control system as when the system is being pressurized by the vehicle engine. The system includes radio or light means (T) to activate the battery powered unit (AP) from a working basket or platform (WB) on one end of the arm device without the use of electrical conduits, or pneumatic or hydraulic actuation lines within the lift arms and without in any way interfering with the conventional lift arms control system established in the working basket or platform. The remotely actuated battery powered pressurizing system is mounted on the chassis of the vehicle and comprises a battery operated motor pump assembly, control means for the motor pump assembly which latter includes a receiver for the signals transmitted thereto by the actuator (T) on the work platform by radio waves or light rays. Provision is also made for preventing the simultaneous operation of the auxiliary pressurizing system and the main pressurizing system operated by the vehicle engine. <IMAGE>

Title: Photographic colour diffusion transfer process
IPC: G03C8/52
Filed: 1979-11-29
Abstract: According to U.K. Application 25436/78 (7918823) a decoratable material (e.g. a woven, grained or embossed material) is decorated by allowing a dye image to diffuse, directly or indirectly, from an exposed and developed photographic element to the material which comprises a mordant. However, in the dark, it is difficult to achieve correct positioning of the element on the material. The present invention provides a dye transfer process which can be carried in ambient light and which may be used for decoration. In the invention the photographic element is protected by two opaque layers one of which is applied after exposure and one of which is permeable to the processing liquid. The processing liquid is applied to the permeable opaque layer and the dye image is allowed to transfer through this permeable layer directly or indirectly to an image-receiving material, e.g. a decoratable surface. The imaged material is then stripped from the opaque layer.

Title: Filtering contaminants from a frying etc. fluid
IPC: B01D29/23
Filed: 1980-01-08
Abstract: In a deep frying cooking process, the cooking takes place within the confines of a filter element 40 immersed in the cooking oil or grease in a receptacle 2 and the filter element continually filters the fluid medium to trap contaminants suspended therein, owing to the turbulance imparted to the fluid by the application of heat. The apparatus includes a straining basket 80 located within the element 40. The said element is typically formed as a bag but may exclude integral stiffening portions to allow it to stand upright instead of being supported by the rim of the receptacle 20. <IMAGE>

Title: Rotating biological film contactor
IPC: C12M3/04
Filed: 1980-06-05
Abstract: A rotating biological film contactor intended for use as a fermenter consists of an elongate horizontal chamber through which extends a rotatable shaft and on the shaft there are mounted spaced support plates 17, with a large number of cords or filaments 18 extending between the plates. Nutrient is flooded into the chamber to partially submerge the assembly of cords and leave an air space above. As the assembly of cords is rotated it cyclically dips into the nutrient and is then exposed to air in the air space above. Micro-organisms adhere to the cords and an adherent culture is built up thereon. Fermentation products can be continuously removed from the nutrient by creating a circulating stream of nutrient through the chamber and recovering the products from that stream. <IMAGE>

Title: A method of monitoring the cooking of food in a steam-pressure cooker and means for carrying out said method
IPC: G01K7/24
Filed: 1980-11-26
Abstract: In a method of monitoring the cooking of food in a steam-pressure cooker, the temperature or the pressure, dependent on the temperature, of the interior of the cooker is measured at 15, and there is produced, as a function of this temperature and a cooking curve for the food to be cooked, an electrical signal the value of which is proportional to the "cooking effect" at this temperature. This electrical signal is integrated at 6 and as a result of the integration there is obtained a variable which increases with the degree of completion of cooking of the food to be cooked. This variable is monitored, and can be displayed at 9. Upon the reaching of a specific limiting value for the variable which denotes the end of the cooking time, a warning signal is produced and/or the operation of the cooker is terminated. <IMAGE>

Title: Fluorescent lighting system
IPC: H01J61/02
Filed: 1981-06-19
Abstract: A fluorescent lamp (10) includes a hollow cathode (12) having an external surface (34) coated with electron emissive material 40 which is heated by the discharge from a first anode (14) disposed internally of the cathode (12), and a second anode (16) is located externally of the enclosed cathode (12) to maintain a discharge therebetween.

As shown in Fig. 3 the cathode 12 and first anode 14 mounted on base 24 form an hermetically closed chamber 32 which is filled with an inert gas such as He, Ne, A, Kr, Xe or H2 at a pressure p of 4-6 mm Hg when the cathode diameter is 0.5cm, it generally being required that p x d is between 2.0 and 3.0. A dielectric barrier 42 may protect the anode from cathode sputtering. The specification also discloses other arrangements, Figs. 4-10 (not shown), in which a cathode emissive surface is so shaped, eg by folding a ribbon, or recessed, eg, by providing slots with opposed surfaces, and provided with a work function of less than 3 electron volts that emission of u-v radiation in response to ionisation of the filling is promoted. <IMAGE>

Abstract: An Aldis-type signalling lamp unit (1 to 18) is provided with means (21, 22, 24, 25) for transmitting a modulated infra-red beam along the visible light beam. A light-emitting diode (22) generates infra-red radiation which is intensity-modulated by voice signals received by a microphone (21). The diode (22) is arranged to be effectively in the focus of a concave mirror (3) by a lens (24) and dichroic mirror (25) such that the infra-red beam is coincident with the visible light beam (11) from a lamp (1). The unit receives a modulated infra-red beam from a corresponding distant unit via a lens (18), dichroic mirror (26) and a photo diode (23). The output of the diode (23) is amplified and relayed to a loudspeaker or earpiece (not shown). The arrangement enables two-way voice or data communication over the infra-red beams between two line-of- sight points in addition to the light beam which is used for alignment and cell recognition purposes as well as for visual signalling if required. <IMAGE>
