Patent GB-2014752-A (GB)
Title: Element for use in optical multiplexer or de-multiplexer
IPC: G02B6/34
Filed: 1979-01-31
Abstract: Optical multiplexers and demultiplexers join together, and separate, light of different frequencies particularly so that they can be transmitted down a common optical wave guide. An element for use in a multiplexer or demultiplexer (shown) comprises a transparent dielectric substrate (60) and at least two transmission filters, (11, 12, 13, 14, 15, and 16) each of which transmits light of a predetermined wavelength and reflects light of other wavelengths. The optical filters are arranged so that an optical beam is transmitted or reflected via each optical filter in turn and in a zigzag fashion with light of a particular wavelength being subtracted or added at each filter in dependence of whether the element is being used as a demultiplexer or multiplexer. When the element is being used as a multiplexer a source of light is provided behind each filter and when the element is used as a demultiplexer a photosensitive detector (71, 72, 73, 74, 75 and 76) is provided behind each filter. <IMAGE>

Title: Decorating Candles
IPC: B44C1/24
Filed: 1979-03-02
Abstract: Candle decorations are produced by rolling wax foil on matrices of plastics, in which a design is indented, thus raising parts of the wax into relief. The matrix is produced by pressing a photo-engraved metal block bearing the required design into a sheet of a heated thermo-setting plastic. The uniformity and surface finish achieved on the wax permits the use of a roller to apply paint to the raised parts. Preferably, the paint used is printers ink.
Patent GB-2017303-A (GB)
Title: Improvements in or relating to vertical seismometers
IPC: G01V1/18
Filed: 1979-03-19
Abstract: A vertical seismometer comprises a horizontal boom 2 carrying a mass 1 frictionlessly pivoted about a horizontal axis 3. The boom is supported by a pre-stressed vertically extending flat spring 4 having one end rigidly attached to the boom adjacent to and intersecting this axis so that movement of the boom applies a turning moment to the flat spring at its attachment end. A further pre- stressed flat spring 5 pivoted at right angles to the other end of the first- mentioned flat spring has its other end rigidly connected to the frame 13 of the seismometer and applies a constant force along the longitudinal axis of the latter spring towards the end attached to the boom. The seismometer may incorporate a negative feedback system (1, 16, 16', 19, 22) that opposes movement of the mass 1 whereby the operating frequency range of the instrument is extended. <IMAGE>
Patent GB-2020866-A (GB)
Title: Memory incorporating error detection and correction
IPC: H03M13/13
Filed: 1979-04-27
Abstract: A memory in which each word location for a user word not only contains the bit locations for the actual data but also one parity bit for the parity over the entire word location and one correction bit. A fixed number of word locations are grouped to form a memory location for the storage of a memory word. When a word location is read by a data user, the parity bit indicates whether the word location contains none or one bit error. If the user word contains an error, the other word locations of the same memory location and also the associated correction bits are read to correct one arbitrary bit error in the memory word. In given cases, a plurality of bit errors can be corrected if they are situated in bit positions of the same rank within the word locations for the user words. The chance that a multiple error has exactly this configuration can be enhanced by a suitable arrangement of the bit locations in a memory. Thus, a limited amount of redundancy suffices in many cases. Memory words in different memory banks may have correction bits in common.

Title: Arrangement for protection against damage due to connection of a battery with incorrect polarity
IPC: H02H11/00
Filed: 1979-08-16
Abstract: An arrangement for protecting a generator and/or the load against damage due to incorrect battery polarity includes an electronic sensor g whose output controls a switching path 5'. One of the battery connection terminals a is coupled to the generator terminal (B+) by way of a switching path 3' controlled by a further relay 3 in series with the switching path 5' and a further switching path 4' controlled by a solenoid 4 connected across the generator terminals. The switching path 5' is opened when the battery is disconnected or is connected with the incorrect polarity and the switching path 4' is opened when the generator is not operating, whereby the switching path 3' is opened to isolate the battery from the generator and from the load whenever any one or more of the latter three conditions is present.

Title: NMR imaging
IPC: G01R33/48
Filed: 1980-07-22
Abstract: The invention relates to small nuclear magnetic resonance pulse head 12 applicable to a body part in the manner of ultrasonic systems.

Title: Air brake system
Inventor: GRAHAM JOHN MACKAY
IPC: B60T13/38
Filed: 1981-11-23
Abstract: A service brake system augments the braking force available while parking without interfering with the operation of the parking brakes.   A pilot check valve (40), connected to the exhaust outlet (48) of a relay valve (18) of the service brake system (10, 14, 16, 20, 21, 22) is controlled by pressure in the spring brake line (28, 46). As long as pressure exists in line (28, 46), the pilot check valve (40) allows unhindered flow between the exhaust outlet (48) and an exhaust port (64) of the pilot check valve. When pressure in line (28, 46) is reduced below a predetermined value to allow spring brake applications the check valve closes to trap residual pressure in the service brake by blocking the service brake exhaust. Pressurizing the service brake line pressurizes the service brake regardless of the condition of the spring brake line. Safety valves may be incorporated in the brake systems to insure that the pressure within the service brake chamber does not exceed a predetermined value (fig. 5, not shown). <IMAGE>

Further pickups in bores 72, 73 are sensitive to axial shifting of shaft 49 which can slide through a central bore of disc 64 and can act on the electronic circuit to divert the data from pickups C1, C2 to other devices. <IMAGE>
