Title: Improvements relating to methods of casting concrete piles and apparatus therefor
IPC: E02D5/36
Filed: 1948-07-15
Abstract: 650,083. Concrete piles. ARMAND, L. July 15, 1948, No. 19072. Convention date, July 18, 1947. Class 68 (ii)] Concrete piles are cast in situ by compacting concrete around the head of a false pile, driving the false pile with the concrete plug into the ground whilst pouring concrete into the cavity so formed, and when the desired depth is reached, applying vibration to the head of the false pile to reliquefy the concrete and then withdrawing the false pile whilst continuing the vibration. As shown in Fig. 4, the false pile consists in an I-section joist 1 with its upper end 2 reinforced and carrying a point 4 at its lower end. Immediately above the point is mounted a ring 3 of shape corresponding to the cross sectional shape of the pile to be formed and which surrounds a combined ram and vibrator 5 operated by compressed air. In operation, the false pile is supported with its head in funnel 9 containing wet concrete. The vibrator is started, causing concrete to compact into a plug or seal under the ram 5 and within the ring 3. Driving is commenced, concrete flowing into the hole around the joist 1. On reaching firm ground, the vibrator is restarted and the concrete around the head reliquefies and flows through space 31 allowing the false pile to be withdrawn. Locally thickened parts 15 and 16 (Fig. 10) of the in situ pile are produced by stopping the vibrator and resuming driving, the concrete compacting under the ram and forcing the concrete below it outwardly. Metal reinforcement can be embedded in the pile as shown.

Title: Improvements in automatic and semi automatic telephone systems
IPC: H04Q3/00
Filed: 1924-08-19
Abstract: 240,605. Western Electric Co., Ltd., (Western Electric Co., Inc.). Aug. 19, 1924. Automatic exchange systems.-A switch having two or more sets of wipers is so arranged that the number of sets effective during the hunting operation of the switch is dependent upon the level to which the switch shaft has been raised. Thus, in the group selector shown, the digit 5 causes both sets of wipers 30 - - 32, 33 - - 35 to hunt and test simultaneously over the fifth and third levels respectively, whilst in response to the digit O hunting takes place over the tenth level only, the lower set of wipers being ineffective. The invention is stated to be applicable also to group selectors provided with arrangements for an eleventh rotary step, and to connectors. Simultaneous hunting over two levels. The five impulses of the first digit are repeated in the usual manner by the line relay IR to the vertical magnet VM in series with relay C which operates the stepping relay E over off-normal contacts S1. Relay E locks up over contacts 49 of the rotary magnet RM and energizes relay F. Upon the relapse of relay C at the end of the digit, the rotary magnet RM rotates the wipers one step and unlocks relay E. If both wipers 32, 35 engage earthed busy terminals, relay E energizes again over contacts 51, 49, 8 and wiper 35, and relay F remains energized over contacts 77, 11, and wiper 32, so that the wipers take a further step and rotation continues until one or other set of wipers find an idle trunk. Suppose now that wiper 35 reaches an idle terminal 65 at the same time that wiper 32 engages a busy terminal 62. Relay F remains energized over wiper 32, but the absence of earth on wiper 35 prevents the operation of relay E and causes the switching relay D to energize in series therewith to extend the connection. Relay F remains locked up throughout the conversation over contacts 77, 10, 8 and lead 78 earthed by a succeeding switch. If, alternatively, terminal 62 is idle when reached by wiper 32, relay F de-energizes as soon as relay E releases, relay D being. no longer short-circuited over lead 78 energizes and the connection is extended over wipers 30 - - 32. Hunting over a single level. In response to the digit 0, an auxiliary vertical wiper 36 engages a grounded terminal 55 so that a relay Z is energized to disconnect relay F. Wipers 33 - - 35 are thus isolated and hunting takes place in the usual manner over the tenth level only under the joint control of rotary magnet RM, stepping relay E, and test wiper 32. Alternatively, instead of the extra wiper 36 and relay F, relay F might be controlled directly by shaft springs.

Title: Improvements in or relating to radio transmission systems
IPC: H04B1/68
Filed: 1959-06-09
Abstract: 920,026. Automatic frequency control systems; muting. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 9, 1959 [June 12, 1958], No. 19699/59. Class 40 (5). In a single sideband suppressed carrier radio transmission system a pilot frequency higher than the highest signal frequency is transmitted and utilized at the receiver to provide a control voltage for automatic frequency control of a local oscillator. As shown, a microphone 1 is connected via a filter 2 having a pass-band of from 0.3 to 2.7 kc/s., an amplifier 3 producing amplitude compression, and an amplifier 4, to a push-pull modulator 7 which also receives an input from a 250 kc/s. crystal-oscillator 6. A filter 8 selects the upper sideband which in a mixer 9 supplied by a 1150 kc/s. oscillator 13 and mixer 10 supplied by a 10,600 kc/s. oscillator 14 is converted to a single sideband signal in the range 12,000.3 to 12,002.7 kc/s. which is transmitted. A 3 kc/s. pilot frequency from an oscillator 32 is supplied to the modulator 7 whereby a pilot frequency of 12,003 kc/s. is transmitted. At the receiver the signal is amplified at 18 and converted to a lower frequency in the range 250.3 to 252.7 kc/s. in a mixer 19 supplied by a 10,600 kc/s. oscillator and a mixer 20 supplied by a 1,150 kc/s. oscillator. A pilot frequency of 253 kc/s. also is obtained and these signals are amplified at 25 and demodulated at 26. The speech signal of 0.3 to 2.7 kc/s. are supplied through a filter 34 suppressing the pilot signal and via an amplifier 30 to the reproducing device, and the 3 kc/s. pilot frequency is selected by a filter 33, amplified at 35, limited at 36, and supplied to a frequency discriminator 37 which is tuned to the pilot frequency. The output voltage of the discriminator through a low-pass filter 39 and frequency corrector 39, e.g. a reactance valve, controls the oscillator 24. In order to reduce the effect of noise on the communication channel, speech signals at the transmitter are supplied to an amplitude detector 40 followed by a low-pass filter 41 having a cut-off frequency below 100 c/s. and through a modulator 42 the amplitude of the pilot signal is controlled so that in the absence of speech signals a maximum amplitude pilot signal is transmitted, this amplitude decreasing with increasing intensity of the speech signals. At the receiver the pilot signal is supplied to an amplitude detector 43 and low-pass filter 44 to recover the envelope signal and control the amplifier 30 so that it is cut off in the absence of a speech signal.

Abstract: 1,005,109. Knitting-machines. I. & R. MORLEY Ltd. July 30, 1964. No. 19858/63. Heading D1C. Alternate frame needles 3 of a straight-bar rib machine are mounted in a separate needle bar 4 from that 2 in which the intermediate needles 1 are secured. The needle bar 4 is pivotally mounted as at 6 to enable the alternate frame needles 3 to be moved to an inoperative position during the production of rib fabric during which machine knitting elements 11, 12 are introduced to occupy positions between the operative intermediate frame needles. The machine knitting elements comprise a hook portion 11 which slides between the blades of a U-shaped slide 12 the hook portion 11 and slide 12 co-operating to form stitches during the production of the rib fabric. For this purpose the hook portions are mounted in a bar 8 and the slides are mounted in a bar 9 the two bars being moved relatively to each other to cause the hook portion 11 and slides 12 to co-operate. To achieve this the bars 8 and 9 are controlled by cam operated bars through pin and slot connections. When it is desired to resume plain knitting the rib loops are projected by the slides 12 and the frame needles 3 which have been returned to an operative position are raised to penetrate the loops on the slides 12, whereafter the slides are retracted leaving the loops transferred on the frame needles 3. Thereafter plain knitting is resumed. Alternatively the alternate frame needles 3 may be pivotally mounted on a shaft supported by the bar for the intermediate needles 1.
