Title: Improved method of concreting shafts, bore holes and the like
IPC: E02D5/36
Filed: 1927-12-21
Abstract: 301,222. Blandford, T., and Gee, A. Dec. 21, 1927. Excavating.-Relates to concreting shafts, bore holes, and the like, and particularly to a method of forming a concrete plug at the bottom of a flooded shaft and sealing it. Cement is first deposited at the bottom of a shaft, preferably by injecting a thick slurry through pipes reaching to the bottom of the shaft, and rubble or like relatively large pieces of material are allowed to drop and sink into the cement. The mass is then allowed to stand, and the operations are repeated until a plug of sufficient size is obtained. After de-watering the shaft, bore holes are driven through the plug and into the fissures &c. whence comes the water, and they are sealed by injecting cement slurry. The cement plug is then removed, and the shaft is sunk further. In a modification of the process, a mixture of rubble and cement is placed on the plug after the first portion has set.

Abstract: 1.030,016. Radio signalling. SIEMENS & HALSKE A.G. Sept. 9, 1963 [Sept. 19, 1962], No. 35450/63. Heading H4L. In a radio relay station having a common local oscillator for the receiver and the transmitter frequency-changers, additional signals are transmitted from the relay station by frequency-modulation of a stagger-frequency oscillator which is provided to introduce a difference between the received and transmitted frequencies, a portion of the baseband being reserved for this purpose. As shown in Fig. 1, an incoming frequency-modulated multiplex signal 1 is supplied to a frequency-changer 2 whose output is fed via a band-pass filter 3 and I.F. amplifier 4 to the transmitter frequencychanger 5 for retransmission via amplifier 6 and filter 23. A common local oscillator 8 co-operates with the frequency-changer 5 via a decoupling circuit 9 and also supplies a frequency-changer 10 receiving a further input from the stagger-frequency free-running oscillator 11. A filter 12 selects the required sideband signal from the frequency-changer 10 for application to the frequency-changer 2 so that the received and transmitted frequencies differ by the required amount. The additional input signals are supplied via a frequency-modulator 24 to the oscillator 11 and in order to maintain the centre frequency of the oscillator 11 constant a portion of its output is supplied to a frequency discriminator 15. The resulting error signal voltage is supplied through a low-pass filter 16, which prevents the output of the modulator 24 from affecting the discriminator 15, to a device 17 controlling the frequency of the oscillator 11. In a modified frequency control circuit, Fig. 2 (not shown), a further frequency-changer receiving the output from the oscillator 11 and the output of a frequency multiplying circuit fed by the oscillator 8 is included in the control loop prior to the frequency discriminator 15 and enables the discriminator 15 to operate at a more suitable lower frequency.
