Patent GB-2071450-A (GB)
Title: Frequency check apparatus
IPC: G01R23/15
Filed: 1981-03-02
Abstract: An apparatus, for example, for a GO/NO GO control function in a chopper controlled traction motor control system is required to permit operation at only the correct chopper frequency and also normal start up from rest when the chopper frequency is zero. A conventional band-pass filter type frequency sensing channel (2) discriminates between operation at correct and incorrect frequencies but cannot respond in the required manner to zero frequency. To permit zero-frequency detection a signal generator (11) is coupled to a second and appropriately responsive channel (3) via a saturable magnetic circuit (13) which is also coupled to the frequency carrying conductor (4). At any operating frequency the magnetic circuit (13) is saturated and the second channel (3) is blocked so that the control function is provided by the first channel (2). At zero operating frequency the signal generator (11) is not blocked and while the first channel (2) is not energised the control function is provided by the second channel (3). The outputs of the first and second channels are connected via an OR gate (1). <IMAGE>

Title: Self-adhesive roofing laminate having self-edge sealing properties
IPC: E04D5/10
Filed: 1981-06-12
Abstract: Improved flexible waterproofing membranes of the preformed pressure- sensitive or self-adhesive bituminous type particularly useful in roofing are described. The membranes are in the form of factory- manufactured, flexible, sheet-like laminates employing (a) a lower layer of waterproofing self-adhesive bituminous composition such as rubberized asphalt non-removably adhered to (b) an upper support layer comprises of a laminate of separate, preformed flexible sheet materials having different coefficients of linear thermal expansion. The uppermost sheet material in the support layer (b) has the higher linear thermal expansion coefficient so that the edges of the applied laminate when exposed to, e.g., solar heating and subsequent cooling, turn downward towards the substrate to be waterproofed, resulting in improved sealability. Additionally, further layers of, e.g., protective films and coatings may be applied to the laminates.

Title: Electro-chemical machining type face characters from solid metal
Inventor: HAYMAN ROBERT
IPC: B23H9/06
Filed: 1981-06-18
Abstract: A print band, daisy wheel or other component carrying type face or embossed detail is made of electrochemically machining the type face or embossed detail from solid metal. The rate of feed of the cathode in relation to the workpiece is controlled in accordance with the cathode-workpiece gap, which is maintained less than 0.010 in (0.25 mm). The gap is measured by metering the volume flow of electrolyte, and the pressure of electrolyte flowing in the gap can be used to clamp the workpiece on a base and maintain good electrical contact therebetween. In print bond manufacture elongate strip 11 is fed in steps to an electrochemical machining area where characters are machined on it, after which it is stepped through the area and a further length of strip is treated. The cathode 15 can slide towards the workpiece in a housing 14 in which it is sealed by O-ring 24 and the leading and trailing ends of the exposed surface of the length of strip being machined are sealed by end clamps 27. <IMAGE>

Title: Indicating device
Inventor: RICHTER HERBERT
IPC: G08B5/14
Filed: 1981-10-16
Abstract: For indicating the proximity of a vehicle to a fixed boundary 14 such as the rear wall of a garage, there is provided a mechanical indicating device comprising a fixed portion such as a housing 1, a feeler bar 13 on one end 3a of a two-armed lever 3 which is mounted at 2 on the fixed portion, and a signal arm 5 which is mounted pivotably at 4 on the fixed portion adjacent the other end 3b of the lever.

Title: Fully enclosed four speed bicycle gearbox
Inventor: HUGHES NOEL LOCKSLEY
IPC: B62M11/06
Filed: 1983-03-29
Abstract: A gearbox has a body 12 which contains a mainshaft 13 driven by pedal cranks 11.

Another gear fixed to this layshaft engages with a gearwheel running on the mainshaft 13 and fixed to a sprocket 10 which is outside the gearbox and which drives the rear wheel by means of a chain. A gearwheel 16 running on a bearing on the mainshaft is in constant mesh with a gear wheel fixed to the layshaft and is brought into operation when dogs on the side of the gear cluster 14 engage with it giving the fourth gear ratio. Gear changes are effected by a normal fork and lever arrangement (not shown in diagram). <IMAGE>

Title: Elimination of interference introduced by switching of the respective channels of a pulse radar
Inventor: DEMAZURE ERIC
IPC: G01S13/64
Filed: 1983-08-09
Abstract: In a pulse radar system comprising several receiving channels (451to 45n) switches (46) are provided to define the distance time gates. These switches produce clutter pulses (76) which are liable to be superimposed on the useful signals (72) when the repetition frequency (fR) is varied to remove doubts regarding the distance measurement. To overcome this problem the signals transposed to intermediate frequency are modulated by a noise signal with a relatively widespread spectrum, upstream of the switches. The intermediate frequency signals are demodulated, downstream of these switches, by means of the same noise signal. The bandwidth of the noise signal used is sufficient to ensure that the level of the spread-spectrum of the clutter is sufficiently low not to interfere with detection of the useful signals, whatever the repetition frequency.
