Abstract: 1302153 Automatic exchange equipment; D.C. signalling INTERNATIONAL STANDARD ELECTRIC CORP 19 April 1971 [21 April 1970] 27146/71 Headings H4K and H4R] A two-way D.C. signalling system includes units at each end of a junction each with a receiving relay and transmitting circuit connected to the junction so that when a signal is transmitted the receiving relay in that unit is short circuited. Since the signals, e.g. meter pulses, may be transmitted during a conversation an induction coil S couples the signal to both lines symmetrically. As shown an earth signal within junctor EU1 is applied at M and passes without delay through diode D1 and resistor R1 to coil S and lines L1, L2. The signal is also applied through diode D2 so that no signal can appear across relay ri which remains inoperative. In unit RE<SP>1</SP> the signal passes through coil S<SP>1</SP>, diode D<SP>1</SP> 3  and causes relay ri<SP>1</SP> to operate thus closing contact ri<SP>1</SP>l to apply an earth to junctor EU2 at E<SP>1</SP>. Similarly if a signal is transmitted in the opposite direction from junctor EU2 to junctor EU1 relay contact ri1 will be operated. In a modified system, Fig. 2 (not shown), an initial sizing signal is transmitted along one line of the line pair and an acknowledgment signal transmitted along the other line. Operation of additional relays in the signalling units in response to these signals connects the units as shown in Fig. 1 so that transmission along both lines is obtained. In this modified system faults on the loop will be indicated by non-receipt of one of these by signals.

In a rake-wheel type haymaking machine wherein a row of rake-wheels 17 are arranged in an oblique row on a frame 1, the central rake-wheel of the row is capable of being turned, into a longitudinallyextending position 19 so that the row is converted into two independent groups, for swath-turning, and the central rake-wheel constitutes a rotary guide-member displacing crop from the first group rearwardly out of reach of the rake-wheels of the second group. For side-delivery (Fig. 1, not shown), all the rake-wheels are parallel and set at an acute angle to the frame, but for swath-turning, the foremost rake-wheel in each group extends parallel: to the frame 1. All the rake-wheels are mounted on cranks 16 carried by stub-shafts 13 pivoted on vertical pins 14 on arms, such as 9, forming part of the frame 1, locking pins 15 and sectors being provided to maintain any adjusted position. In addition, the central rake-wheel is also adjustable about a horizontal longitudinal axis 22 so that the plane of the rake-wheel 19 need not be vertical when the rake-whell constitutes a guide-member. The frame 1 is mounted on hitch-links and includes an attachment-frame 4, 6, with pins 5 to receive the hitch-link ends. For transport, the foremost rake-wheel can be swung, on an arm 10, about a pivot pin 11 which extends obliquely in a longitudinal plane, so that the arm can be stowed close to the towing tractor. The rear part 18 of the frame is detachable, for the same purpose.

Abstract: 497,593. Analysing concrete. WINGET, Ltd., and STANCLIFFE, C. W. June 21, 1937, No. 17229. [Class 82 (ii)] [Also in Group V] A method for the analysis of concrete to enable the proportions of the constituents to be determined comprises washing a sample of the concrete before hardening through a series of sieves of successively decreasing size of mesh so as to separate the sample into portions consisting of cement, sand or fine aggregate, and one or more grades of coarser aggregate respectively. In the apparatus shown in Fig. 1, graded sieves 1, 2, 3 are supported by a cradle 4, and the whole suspended by a spring 8, within a. container 6. A known quantity of cement is placed on the top sieve and the container filled with a known weight of water. The cradle 4 is agitated so that the grades become separated on the sieves and the cement passes through. The proportions may be estimated by weight or volume. The container may be of glass or transparent material or may comprise a glass window, and may be supported from the balance 5 or from a stand or may rest on the ground. Means may be provided for raising the sieves above water for weighing purposes. In the apparatus shown in Fig. 2 the sample of concrete is introduced into the inner sieve through the chamber 20 and the cover 22 is replaced. The sieves are rotated by the crank 26. After separation the grades are dried and weighed. They may be removed by means of the plugs 16, 17, 18, 19. The fine sand which has passed through the finest sieve may be separated by further washing. The bearing 25 is such as to allow substantially universal movement of the sieves.' Either form may be arranged as a battery of units.

Title: Method and apapratus for correcting statics in seismic data
IPC: G01V1/00
Filed: 1973-04-11
Abstract: 1422657 Seismic signal processing TEXAS INSTRUMENTS Inc 11 April 1973 [17 May 1972] 17330/73 Heading H4D Static corrections, for seismic trace data having subsurface redundancy, are determined by selecting and grouping event-representative wavelets on the traces, summing those wavelets associated with common shot points, summing those wavelets associated with common receiver positions, and determining the time intervals each between a selected peak of a resulting summation wavelet and the centre of the summation wavelet. In the Fig. 2 embodiment the input data at 20 are common depth point (CDP) trace gathers filtered and prior-processed for approximate static correction. Travel-time and velocity data for reflector segments are input or calculated at 22. The "beat" segments are selected at 24 (on a length, velocity, position and amplitude basis), smoothed at 44, and used to calculate the associated event travel-times on individual traces of the CDP gathers. Wavelets in timegates centred on these calculated times are then picked from the traces and grouped at 46 according to CDP, shot-receiver offset, shot point and receiver position, thereby defining wavelet "maps". Wavelets picked from a common trace may be stacked at 72 (since they have a common static error) to condense the data and to enhance the signal-to-noise ratio (Fig. 9, not shown). The wavelet maps or stacked wavelet maps are input to stages 90, 92 where wavelets associated with common receiver positions are summed and wavelets associated with common shot points are summed. Peaks in the summation wavelets are selected (Fig. 10, not shown) and their time separation from the wavelet centres are determined at 94, 96 to obtain the receiver and shot stator corrections respectively. The corrections are applied to the wavelet maps and the summation and determination stages 90-96 are iterated to obtain improved corrections. These are then applied at 134 to the CDP traces and stages 20-134 are iterated to improve the corrections further. A file of the final corrections is obtained at 136.

Filed: 1969-04-02
Abstract: 1,218,304. A yarn breakage detector. TEIJIN Ltd. 2 April, 1969, No. 17396/69. Heading B5B. A broken yarn detector is shown schematically in Fig. 1 in which yarn 2 from spinneret 1 passes under tension through a broken yarncollector 6, over an oiling roller 3 and thence via roller 4 to a tensioning roller 5. Breakage of the yarn can occur either before or after roller 4.  If the breakage occurs before roller 4, the tension is relaxed and yarn begins to build up on the collecting device 6. As a result of the build-up a light beam from the source 8 is broken, the output signal from the photodetector 9 is reduced, the output current of the amplifier 10 is reduced and the electromagnet 11 is de-energized. In this manner switch 12 is thrown. This sequence of events can be used to activate buzzer 13, light warning lamps or stop the spinning process. If the breakage occurs after the roller 4, the yarn wraps itself around roller 4 and begins to build up. When the build-up of yarn reaches peg (16) on the flange (15) which is rigidly attached to the fixed shaft (14) (Fig. 3, not shown), the roller 4 is halted as a result of the friction between the yarn and the peg (16). From this instant the apparatus functions as explained above.

Abstract: 612,958. Control systems for discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. June 11, 1946, No. 17473. Convention date, June 7, 1945. [Class 38 (iv)] A circuit for starting and running discharge lamps or fluorescent lamps has an inductance 10 and a resistance 11 of high negative temperature coefficient in series with the electrodes 2 (at least one of which is thermionic) and in shunt with the discharge path, and a condenser 9 is included either in this portion of the circuit or in series with the stabilizing inductance (as shown), according as the lamp is to run on lagging or leading current. The circuit is arranged to resonate at the supply frequency and the resistance 11 prevents effective resonance until the electrode (or electrodes) has time to heat sufficiently for ionization. After striking, the resistance 11 cools and substantially reduces the shunt current. Modifications for the running of two tubes in series are described, in one of which adjacent electrodes of the tubes are heated by a winding inductively related to the inductance 10. The resistance 11 need not be heated by its own current.
