Title: Angular values analogue-digital convertor - with angles defined by trigonometric values which enables low cost digital components to be used
IPC: H03M1/00
Filed: 1973-12-10
Abstract: The method is for converting analogue values of angles into digital values by which a electrical voltage representing the analogue value to be transformed is compared with a time variable voltage in order to permit clock pulse counting up to equality of the representative voltage with the variable voltage. From the electrical voltages representing the side and cosine of an angle, one compares these voltages with a sinusoidal voltage and amplitude of the sinusoidal voltage is maintained at the value for which the sinusoidal value representative of the sine and cosine values of the angle.

Title: Electromagnetic switching of conductor matrixes - matrix junctions set in ferromagnetic pole pieces with pivoted switch arm
IPC: H01H67/26
Filed: 1974-06-07
Abstract: A co-ordinate switching system for a matrix of rows and columns of conductors includes mechanical elements at each intersection. The individual intersection connection is controlled by a circuit associated with the columns and common to each switch element and a second circuit associated with the rows. The matrix is made up of 'GO' and 'RETURN' conductor paths (114, 115) set up at right angles to each other, each junction having a ferromagnetic pole piece (118, 118a', 118b, 118b') in each right angle so formed and set in an overall 'yoke' (117). The pole supporting plate is set in the plane of the matrix as is the armature (111) pivoted at its centre which itself is at the matrix intersection centre. Currents in the conductors energise the armature and reverse it position.

Title: Reinforcement for cementitious building components - or tar or bituminous coatings, is a fibrous network and may be of metal or synth. material
IPC: E01C11/16
Filed: 1974-10-08
Abstract: A reinforcing element for cementitious building components or tar and tibuminous coatings is fibrous and forms a network. It may be of metal (wire) and/or synth. material e.g. polypropylene. The reinforcement takes up tensile or compressive stresses. Any cracks formed, e.g. by variations in temperature are kept very small as they are stopped by the reinforcement during crack propagation and are also relatively evenly distributed throughout the component. The network may be rolled or twisted inside the component. The reinforcement may contain a (water-sol.) adhesion adjuvant. The fibres composing it may be filamentous or tape-shaped. Both they and the network may be "structured".

Title: Roller bearing with inner and outer race - has plastics liner within inner race with a retaining flange
IPC: F16C27/06
Filed: 1975-01-06
Abstract: The roller bearing has two concentric races between which are arranged cylindrical rolling elements. The outer race has inwards turned edges which retain the free ends of the rollers. The pressed steel inner race provides radial support for the roller. This inner race with an end flange can be pushed out of the bearing. An additional plastics sleeve is pushed into the inner face and the retaining flange of this plastics sleeve completes axial restraint for the bearing inner race. This inner lining may be splined so that polygonal shafts such as rectangular, triangular or other cross sections can be inserted into the bearing. The plastics sleeve also compensates for deviations in the tolerances of the shaft. Effective damping is also provided by the plastics sleeve. In another version the outer race may also be covered with a plastics sleeve. The inner plastics sleeve can be inserted for example on fitting while the bearing has been transported separately.

Title: Solar energy heater for house roof mounting - comprising corrugated sheets of steel and an integral water reservoir
IPC: F24S10/50
Filed: 1976-12-30
Abstract: Solar energy heater for fitting into the roof of a building, to be used for heating, air conditioning and the distributing of hot water. The heating element consist of two undulating sheets of steel, 1mm thick, joined together in the valleys. The face exposed to the sun is coated with a preparation to enhance its absorption properties. A reservoir behind the sheets contains a serpentine from which water is distributed through the house. A thermostat interrupts the circuit of the heating part when its temp. drops. An electric heater is incorporated, which comes into operation when the water temp. in the reservoir is too low to heat the water in the serpentine to the required temp. The heating element described can be integrated directly into the roof of a building with very little modification of the framework. Each unit has its own reservoir, thus removing the difficulty of putting a large reservoir in existing framework.

Title: Remote equipment monitoring by two=way telephone lines - involves central unit which determines whether transmitted call are normal or monitoring calls
IPC: H04M11/04
Filed: 1977-02-11
Abstract: The remote supervision system(1) uses two way telephone lines. The system has a central unit and a series of peripheral units which are to be supervised. The central unit has an automatic call detection circuit as well as a call pulse switching system. The switching system routes calls either towards a normal unit in the case of a normal communication or towards a decoding circuit in the case of a coded message. The decoder is followed by a printer for reception of an automatic transmission of a coded message. The coded message identifies the transmitting remote unit and its state. The central unit ensures transmission of a returning end of message signal and or anomaly signal. If the caller is the detection unit of the supervised peripheral unit. The central unit decodes the message and transmits it to the printer with an eventual error indication. The message is retransmitted until the printer receives a correct message.

Title: Reproduction and recording material marking - uses liq. crystal partially to block illumination falling on recording medium
IPC: G03C11/02
Filed: 1977-02-15
Abstract: The method is designed to produce reference marks on reproduction or recording supports. The method uses a surface whose physical or chemical properties vary when they are struck by a luminous beam. An obstacle is placed in the patch of the source of radiation. The obstacle stops at least partially the radiation from the source, striking the support. The obstacle is arranged to correspond to the references that one desires to insert onto the support. The obstacle consists of a liquid crystal which is excited electrically. The transparency of the liquid crystal can be varied by altering the excitation voltage as a function of the reference required to be carried on the support. The liquid crystal excitation is controlled by electrical circuits connected in series or parallel. A second liq. crystal is used to permit visual control of the state of the first.
