Title: A press for use in conjunction with a container for meat and other foodstuffs
IPC: A22C7/00
Filed: 1934-06-09
Abstract: 439,886. Meat &c. cooking-vessels. CALDWELL, W. J., Rome Hall, Brierfield, Lancashire. June 9, 1934, No. 17117. [Class 66] [See also Group VI] A press for use with a container E for meat and other foodstuffs consists of a bar A fitted with a spring-pressed plate C extending wholly or partly over the top of the container E, the ends of the bar A engaging with ratchet teeth d, projections or other interlocking surfaces formed on spring uprights D<1> attached to or forming part of a base D. In one form, a bar a<1> U-shaped in the centre is riveted to bar A, and passing through holes in both bars are guide rods c and a rod B all attached to plate C between which and bar a<1> a spring b encircling rod B extends. The plate C bears on a plate E<1> placed over the contents of container E. The uprights D<1> extend through holes a in the bar A. The base D may have pivotally attached to it a metal strip which may be turned at right angles to form a stand. When the container E is that in which the foodstuff is to be kept, the plate E<1> is soldered &c. to the container when it contacts with the mouth thereof. In a modification, Fig. 3, the uprights D<1> are riveted &c. to a metal base G formed with annular corrugations g serving to locate containers H of different sizes, The container H may have an internal flange h formed with annular corrugations h<1> to support a loose plate h<2> having corrugations h<3>. Grease-proof paper may be inserted as a seal between plate h<2> and flange h. In a further form, additional adjustment of the pressure is obtained by attaching the spring-pressed plate C to a U-sectioned bar all, Fig. 4, which passes through a U-shaped aperture in bar A and has ratchet teeth a<12> engaging with a spring a<14> pivoted to bar A.

Title: Improvements relating to signalling transformer apparatus for use in dangerous atmospheres
IPC: H01F27/40
Filed: 1950-07-10
Abstract: 700,911. Transformer arrangements. DAVIS & SON DERBY, Ltd., J.. and DAVIS, W. H. Oct. 10, 1951 [July 10, 1950], No. 17146/50. Classes 38 (2) and 38 (4) A signalling transformer apparatus of the intrinsically safe type (as defined in British Standards Specification 1259:1945) has a small wattage indicator lamp 15 connected directly across the secondary winding of the transformer and which is visible through a window in the flame proof casing 13 of the apparatus, the lamp being so arranged that the current which it consumes does not reduce the intrinsically safe output available from the transformer for signalling purposes. The intrinsically safe output is taken from terminals 12, 12a, the secondary winding in series with a current limiting resistor 17 being connected between these terminals. A terminal board 20 may be arranged to carry the indicator lamp ; the resistor 17 may also be wound thereon. Thus a failure is indicated without unnecessary opening of the flame proof casing.

Title: Improvements in or relating to Carburation Systems for Internal Combustion Engines.

Filed: 1917-11-22
Abstract: 120,952. Holley Bros. Co., (Holley, G. M.). Nov. 22, 1917. Vaporizers, external.-A nozzle K, Fig. 3, may be put into communication with either of two float chambers C, Fig. 2, and delivers fuel into air which is admitted through the annular space 0, the mixture formed passing through a pipe F, which is coiled round the exhaust passage, to the induction pipe B through a lateral opening in a removable choketube I below the throttle valve. The bulk of the air to form the mixture is admitted past a hand-controlled valve and a suction-actuated sleeve S sliding over prongs T. The nozzle K is controlled by a conical gravity valve L provided with a slow-running passage N; the lift of the valve is limited by splitting and expanding the lower end of its stem M. The inner wall of the exhaust passage in which the coil F is located is slidable in order to vary the number of coils exposed to, and therefore the heating effect of, the exhaust gases.

Title: Improvements in or relating to carrier-wave telephone transmission systems
IPC: H04B3/04
Filed: 1954-06-11
Abstract: 762,898. Carrier transmission. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 11, 1954 [June 16, 1953], No. 17221/54. Drawings to Specification. Class 40 (4). In a multi-channel carrier system the cable length between repeaters is chosen to be such that the slope of the attenuation/frequency curve is approximately 6 dB. per octave and that the total maximum attenuation between repeater points at the highest frequency transmitted is less than 30 dB. This reduces crosstalk and also permits the use of less complicated equalizers. With the amplification factor of the repeaters being 30 dB. or less, frequencies up to 300 Kc/s. may be employed in normal low-frequency cables in a few side circuits in each direction without the near-end cross-talk exceeding the normally acceptable level, while for phantom circuits of star-quad cables, frequencies of 500-600 Kc/s. may be used. The indirect far-end cross-talk is reduced to such a level that it becomes unimportant compared with the direct far-end crosstalk which can be balanced out in a simple manner. By suitable systematic choice a number of circuits are chosen in conventional low-frequency cables which are satisfactorily free from far-end cross-talk up to high frequencies so that a greater number of channels are made available than would be obtained by using a larger number of pairs with the lower frequencies which would then be necessary owing to the stronger cross-talk couplings between them. The equalization network is included in the negative feed-back path of the repeater, and may be constituted by a dipole formed mainly by a capacitor included in the ,cathode lead of the amplifying tube. The slope of the amplification curve of the amplifier is thus approximately 6 dB. per octave matching that of the cable section. To compensate for the deviation of the cable curve at higher and lower frequencies respectively, a small inductor is connected in series with the capacitor, and a resistor is connected in parallel with the capacitor. The effect of cross-talk is also reduced by arranging that on the lefthand and right-hand side of each repeater point all conductors used for carrier working and having the same twist lengths are connected to the input side of the amplifiers concerned, and the output sides are connected to conductors having different twist length, so that the same level prevails in the conductors of equal twist lengths and the near-end crosstalk therefore occurs between points of equal level and is less disturbing than if it occurs between points having different levels. Filament and anode current is supplied to the repeaters over the cable. The former may be supplied as alternating current and the latter as direct current.

In a device for the automatic removing and stacking of e.g. sewn workpieces from a sewing machine, the workpiece 2 is removed from a clamp 78, Fig. 2, by transfer means 8 on to a horizontal pick-up gate 1, 3, which is actuated to move in a rectangular path to deposit said workpiece on a stack 5 in a magazine 4, 6. As described, stack 5 rests laterally against a gate 6. The pick-up gate 1, 3 is moved in vertical and horizontal directions by compressed-air cylinders 42 and 30, respectively; the transfer means 8 is moved horizontally by a cylinder 10 which is pivotably movable in a vertical plane by a cylinder 25, so that the gripping means 16 can be lowered on to the workpiece 2. Although raisable by cylinder 42, the pick-up 1 falls under gravity and downward movement can be limited by the action of a braking cylinder (59), Fig. 5 (not shown), frictionally on a rod 37. In operation, see also Figs. 7-10 (not shown), the means 8 transfers the workpiece on to the rods 3 of pick-up 1 which is then allowed to fall to rest on stack 5; electromagnetic control means then actuates braking-cylinder 59 to limit vertical movement and cylinder 30 to move pick-up 1 laterally towards the right, whereby the workpiece is deposited on stack 5. The pick-up 1 is subsequently raised and moved back to the left to receive the next workpiece.
