Title: Improvements in and relating to trunk communication electric cables
IPC: H01P3/04
Filed: 1935-02-23
Abstract: 438,560. Cables. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Feb. 23, 1935, No. 5895. Convention date, April 18, 1934. [Class 36] A communication cable, more particularly for high-frequency working, has one or more core groups each comprising two or more conductors separated from one another by air space insulation, the conductors of each core group being supported within a sleeve by distance pieces or supporting members in such a manner that the outer surface of the conductors is mostly or wholly in contact with the air of the air space insulation. The extent to which the distance pieces or supporting members constitute part of the dielectric between the conductors and the sleeve is greater than the extent, if any, to which they constitute part of the dielectric between the conductors themselves. Fig. 1 shows a cable having a single core group consisting of conductors 10, 11 separated from each other and from a surrounding sleeve 14 by spaced insulating washers 12 and insulating strips 15 respectively. The sleeve 14 may be of insulating, conducting, or magnetizable material. A water-tight sheath 16 completes the cable. The washers 12 may be dispensed with if the conductors are cemented to the strips 15 and the strips cemented to the sleeve 14. In a modified construction, the strips 15 are replaced by a cord which is wound helically around the group of conductors. In a further embodiment, tubular conductors 40, 41, Fig. 5, are carried by beaded portions provided on the legs of T-shaped supporting members 42, 43, and the sleeve surrounding the conductors is formed by curved strips 45, 46, the edges of which engage in slots 44 provided in the heads of the T-shaped members. A water-tight sheath 47 completes the cable. An insulating sleeve may be provided immediately under the sheath 47. The conductors 40, 41 may be formed by electrolytic deposition on the beaded portions of the supporting members, or the conductors may be of bent copper strip, the edges of the strip being pressed into cuts or recesses 44 in the beaded portions. The supporting members, which may be provided with recesses or cut-out portions, such as 50, 51, Fig. 6, to reduce the capacity of the cable, are preferably formed of a polyvinyl compound, such as polystyrol, or of a mixture of polystyrol with guttapercha, balata, rubber, artificial resins, or waxes.

Title: Race game apparatus
IPC: A63F9/14
Filed: 1935-02-25
Abstract: 438,097. Race games. GUEYDAN, A., 6, Avenue des Toises, Lausanne, Vaud, Switzerland. Feb. 25, 1935, No. 5906. [Class 132 (ii)] A race game apparatus comprises a reciprocating track, runners which are so shaped that they shuffle backwards and forwards on the track within narrow limits without progressing from one end to the other, and means to indicate the end of the race irrespective of the leading runner's position on the track. The track 3 consists of a plate 14 with transverse slots 15 and parallel bars 13 forming grooves within which move the runners 16 having teeth or roughnesses 17 which coact with the slots 15 as the wooden track is reciprocated so that the runners are shuffled backwards and forwards in the race. The track is reciprocated by a hand crank 12, wheels 7 and 8, cranked axle 9 of wheel 8 and a rod 10 attached to a plate 11 fast with the track. Crank 12 may be actuated by a clockwork, electric or other motor. Above the track is a fixed surface 5 on which is represented most of the sky. Between the surface 5 and the track 3 is a band 4 on which is represented the lower part of the sky, the track barrier, spectators and the starting and winning posts. This scenery band passes round vertical rollers such as 23 and is driven unidirectionally by a strip of panne velvet 21 attached to the side of the track. A fixed strip of panne velvet prevents retrograde movement of the band. There may be a scenery band on each side of the track. The rod 10 may be bent or flexible, or the plate 11 resilient to damp track vibrations. The race may be illuminated and a small size apparatus may be projected and enlarged upon a screen. The end of the race may be signalled (1) by a mechanical bell, the clapper of which is oscillated by holes in the scenery band, or (2) by an electric bell ; two contacts in the bell circuit are separated by the band which has a metal plate to close the circuit at the appropriate time. The apparatus may represent boat, motor, or other races. Instead of the runners having teeth or roughnesses, each one may have a pair of projections which straddle parallel bars reciprocated relatively to the base plate. The apparatus may be combined with coin-freed mechanism. Specification 399,383 is referred to.

Title: Improvements in or relating to pectin jelly compositions
IPC: A23L29/231
Filed: 1947-03-03
Abstract: In making compositions for the jellification of edible mixtures of low sugar type, e.g., for making jellies containing fruits, vegetables or soup stock, such as aspics, madeleines or consomm<\>aes, a pectin which has been de-methoxylated to an extent sufficient to form a jelly in low concentrations of sugar is mixed with a pectin de-methoxylated to a lesser extent to reduce syneresis in a finished jelly, e.g., a pectin of equivalent weight 250-350 is mixed, in the proportion of 5-20 per cent, with a pectin of equivalent weight 400-600, such equivalent weights being determined by titration with standard sodium hydroxide solution.  An edible salt of calcium or magnesium is preferably included in the mixture for jellification.  The examples are concerned with syneresis measurements on jellies consisting of the pectins, tomato juice, salt or a spice mix containing salt, citric acid, and tricalcium phosphate.

Title: Measuring and counting systems
IPC: B24B49/00
Filed: 1971-03-05
Abstract: 1382807 Gear-grinding CRANFIELD INSTITUTE OF TECHNOLOGY 24 Feb 1972 [5 March 1971] 6194/71 Heading B3K [Also in Divisions G4 and G1] In apparatus for sensing the relative displacement between two members one of which carries a scale grating 1 (Fig. 1), the other carrying a sensing head 9, the angle of the scale grating relative to the direction of relative displacement is adjustable to vary the number of output pulses from the sensing head 9 per unit of displacement. As described the scale grating 1 is attached to a member 6 having a number of holes 7 to receive the shank of bolts slidable in a groove 8 in a fixed support. The sensing head 9 which includes a scale grating 10 to produce MoirÚ fringes detected by one or more photodetectors 11 is similarly adjustable relative to movable member 12. In a modification (Fig. 4, not shown) the sensing head moves along a centre line of the grating in a guideway (38) and is biased by a spring (36) against a bracket (37) moving at an angle α to the scale. The apparatus may be used to effect measurements when grinding spiral or helical gears (Fig. 3) in which rotary encoders 20, 25 detect respectively the radial movement of grinding wheel 14, which is of helically ribbed form carried, together with its synchronous A.C. motor 15, in a wheel head 16 and the workpiece 17, carried together with its direct drive servo torque motor 19 in support 18. The encoders each comprise lined discs co-operating with diametrically opposed reading heads (so that eccentricity errors may be eliminated) and feeding output pulses to the up and down inputs of a counter 29 via multiplier/divider circuits 24, 28. Initially circuit 24 is such that its output signal is of the same frequency as the output from encoder 25 when the workpiece 17 is running in correct engagement with grind wheel 14. The counter output is fed via a digital/analogue converter 30 to amplifier circuitry 31, also receiving a voltage signal representing the frequency of the output of circuit 24. The amplifier circuitry 31 controls the servomotor 19 of the workpiece. In the grinding of spiral or helical gears the speed of rotation of the workpiece 17 must be modified by a factor dependent on the lead of the workpiece and the rate of cross feed relative to the grind wheel. This is effected by including the linear encoder of Fig. 1 or Fig. 4 between the support 18 and a frame member, the output pulses from the encoder, after division/multiplication in a circuit 34, being either added to the pulse train from encoder 20 or the pulse train from encoder 25 in dependence on whether the spiral angle of the workpiece gear is righthand or left-hand. The angle α at which the linear encoder is positioned relative to the direction of movement is determined in dependence on the helix angle, the lead of the spiral and the number of grating lines on the linear and rotary encoders.
