Abstract: 1,202,574. Rear view mirrors. DESMO Ltd. 14 Oct., 1968 [23 Aug., 1967], No. 38808/67. Heading B7J. A rear view mirror comprises a mounting plate member 13, which is adapted to be secured by screws 17 wholly on the exterior surface of a vehicle, and is housed and substantially concealed with a peripheral skirt portion 20 of a base 12, the base 12 being detachably mounted on plate 13 by a locating engagement between a camming end 14 of plate 13 and a cooperating recessed portion 21, 22 in the base, and also by a locking engagement formed by a screw 24 passing through a clearance hole 23 in the skirt 20 and threaded into the other end 15 of the plate 13, so that upon locking engagement, the locating engagement is also locked and, in use, the base cannnot be separated from the plate 13 along a path normal to a plane tangential to the vehicle surface. The mirror head 10 is attached to a stem 11 integral with the base 12. In a first arrangement, the recess 22 tapers inwardly and the plate end 14 is similarly tapered so that locking occurs where the sides of the tapes engage. Alternatively, the end 14 is a clearance fit in recess 22 and locking occurs when the edge of skirt 20 engages the vehicle surface via a rubber or plastics gasket. In a second embodiment, a rectangular opening in the plate end 14 cams with either a tapered or clearance fitting torque on the base, Fig. 3 (not shown). Similarly, a frusto-conical or cylindrical peg on the base may engage in an opening in the plate end 14, Fig. 4 (not shown). In a further embodiment, skirt 20 flares outwardly and an inner inclined surface of plate end 14 engages a cylindrical peg mounted transversely in the base, Fig. 6 (not shown). Fig. 7 (not shown) shows a toe and heel projection on the base engaging a hook-shaped plate end 14, the axis of the locking screw 24 being arranged at right angles to the plane of plate 13. In the embodiment of Fig. 5 (not shown), the plate end. 14 cams above an inclined surface projecting from the free edge of the skirt, and the locking screw 24 is threaded through the base to bear in a recess in the locking end 15 of plate 13.

Title: Multichannel signal system

Abstract: 806,087. Multiplex systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 21, 1956 [Dec. 22, 1955], No. 39002/56. Class 40 (4). [Also in Group XL (c)] In an eight channel, single-sideband, frequency division multiplex signalling system, the upper sideband of one channel is paired with the lower sideband of a second channel, by causing their lower and upper sidebands respectively to coincide, and removing this coincident band by a filter; other pairs of channels being similarly treated and arranged so as to interleave with the "gaps" left by the filters between the sidebands of the other pairs. The input of channel a is mixed in a balanced modulator 3a with the output f2 of a local oscillator, and channel b is similarly mixed with f3. Frequency f3 is higher than f2 by the bandwidth of the signal channels so the upper sideband of channel a coincides with the lower sideband of channel b. This unwanted band is removed by a filter 4a leaving the lower sideband of channel a and the upper sideband of channel b with a " gap " in the spectrum between them. The local oscillation f3 is also mixed with channel e, this time in modulator 3e, and channel f is mixed with f4. Frequency f4 is higher than f3 by one bandwidth and filter 4c removes the overlapping sidebands. The lower sideband of channel e fits into the "gap" between the selected sidebands of channels a and b and the upper sideband of channel f continues the spectrum above the upper sideband of channel b. The remaining 4 channels are similarly paired and interleaved.

Abstract: 844,451. Tea concentrates. UNILEVER Ltd. Dec. 21, 1956 [Dec. 21, 1955], No. 39075/56. Class 129. A hot aqueous extract of tea leaves substantially free from undissolved material is cooled to a temperature at which an insoluble precipitate of 5 to 25 % by weight of the total tea solids dissolved in the hot extract is formed which is then separated from the solution by centrifuging. Preferably the hot extract contains at least 3 % soluble tea solids of which 10 to 20% is precipitated and is preferably cooled to between 7‹C. and 40 ‹C. the temperature being held for at least half an hour. The centrifuge is preferably operated with no air space. The leaves are introduced into a counter current extractor at 12 and are steeped in a hot solvent, introduced at 15 until an extract is produced having a concentration of at least 3 % soluble tea solids when the extracted leaves are removed at 11. The dilute extract, usually containing 3 to 5 % tea solids withdrawn from extractor 10 through pipe 16, may be passed through strainer 21 or may be centrifuged e.g. at about 60 ‹C. It is then pumped through jacketed heater 22 into vacuum flash chamber 251 maintained at 630 to 730 mm mercury. In chamber 25<1>, about 20 % of the water is evaporated along with volatile tea constituents and is removed through pipe 26 leaving behind the dearomatized extract which is collected in tank 27, precooled at 28 and pumped to storage vessel 30 and contains about 4 to 6 % soluble tea solids. This extract is fed to cooler 31 where the temperature is reduced to produce precipitation and then passed to a centrifuge 32 from which the insoluble precipitate is withdrawn periodically at 35. The extract flows through pipe 36 to vacuum concentrator 37 e.g. one having an evaporation chamber 37<1>. Effluent from concentrator 37 flows through pipe 40 to vessel 41 and the distillate is condensed in condenser 42 and withdrawn. Dilute vapour flows through pipe 26 and is introduced at an intermediate point of fractionating column 47 through a pump and a pipe. Examples are given using Ceylon, Sumatra, Java and South India black tea.

Abstract: 338,416. Barr & Stroud, Ltd., and MacGill, C. D. Dec. 27, 1929. Indicating. - An apparatus for determining the mean of two values comprises a pair of transmitting and storing-up devices whereby the values can be imimediately or subsequently transmitted to two elements of a differential mechanism the third element of which has a movement imparted to it in accordance with the mean of the two values. As shown applied to the determination of the mean range from the range readings communicated from two range finders through worms 1 and 12, each worm drives a wheel 2 provided with a pin 7 lying between a pair of arms 8, 9, associated with the members 3, and 6 of a transmitting and storing up device as described in Specification 129,124, wherein the said members are connected to the opposite ends of a coiled spring. A second pin 10 resting between each of the pairs of arms 8, 9, is secured to a wheel 11 to transmit the movement through a pinion 18 to the corresponding element 19, and 21 of a differential mechanism the third or jockey element 22 of which receives a movement proportional to the mean of the other movements. The elements 19, 21, and 22 are associated with pointers 24, 25 and 23, co-operating with a single scale plate. When desired a pointer 26 can be made to follow the movement of the mean pointer 23 by rotation of the handle 27 to transmit the movement to a distant station. This transmission if desired may be effected automatically by gearing 31, 32 associated with the jockey element. 22 driving a transmitter 33. The wheels 11 may be locked by electromagnetically operated pawls 34 to prevent actuation of the pointers until such time as the observations are desired.
