Abstract: 1,257,062. Railway ballast tamping machines. CANRON Ltd.-CANRON LIMITEE. 3 Jan., 1969 [15 Jan., 1968], No. 622/69. Heading E1G. In a ballast-tamping vehicle comprising first and second tamping heads 21, 22 respectively straddling sleepers T1, T2, the loading head 21 is fixed on the vehicle chassis 24 while the head 22 is movable longitudinally by a motor 30, there being provided automatic first and second control means controlling the vehicle brakes and the motor 30 in response to photo-electric, magnetic or mechanical sleeper-sensing devices so that the machine is automatically stopped with the heads 21, 22 precisely over their sleepers irrespective of variations in sleeper spacing. As shown the movable head 22 is mounted on a wheeled sub-frame 25 actuated by a hydraulic cylinder fed by a pump 32 on the vehicle wheels 33. The control means shown comprises two photo-electric detectors 40, 41 (one for each head) which overlie different rails. Each detector has a light transmitter and a receiver responding to spots of paint which have been applied to the rails by a preceding car 10. The car 10 may be an independent inspection car or a satellite survey car and carrier for each rail a solenoid-valve-controlled paint applicator 13 so that paint spots may be applied - e.g. to alternate rails - either by an operator, or automatically by a sleeper-switch 18. The relative positions of the paint spots, detectors and tamping heads are chosen to allow for vehicle braking distances. As shown the detector 40 is telescopically adjustable in relation to the fixed head 21 to compensate for effects of gradient on braking distances. The paint spot and light detector may, in a modification be replaced by a metal sleepertack and magnetic detector.  In an alternative control means dispensing with the car 10 the vehicle itself carries for each of the two tamping heads a sleeper indexing switch 50, Fig. 2, comprising a vertically retractable frame 51 carrying a pivotal sensing element 52 actuating a micro-switch FT1 through a cam and push rod. The two micro-switches are incorporated in respective counting and time delay circuits, Figs. 5, 6 (not shown) which are energised through contacts (CR1, CR2) closed by the raising of the tamping heads. The vehicle may be provided with automatic inching mechanism and with a third adjustable sleeper-sensing element to detect overshoot.

Abstract: 1,257,231. Electro-statographic processes. ELECTROPRINT Inc. Feb.25, 1969 [March 1, 1968 (2)], No. 10048/69. Heading G2H. An electrostatic latent image comprising two layers of opposite charge is formed on the insulating layer of a screen comprising apertured insulating and conductive layers 21, 23 and the screen is exposed to a source of ions which are repelled by the field of the charged parts of the screen and pass through the apertures in the unchanged parts to form a charge pattern in image configuration which is used to form a reproduction of the image. The latent image is formed on the screen by charging the surface of the insulating layer while holding the conductive layer at a fixed potential whereby the double layer of charge is produced as shown in Fig.3. This provides better field definition than a single charge layer. Preferably the insulating layer is photo-conductive and suitable screen constructions are described with reference to Figs. 4a, b, c (not shown). In the embodiment of Fig.7, an endless screen 51a comprising a photo-conductive layer 50a and an earthed conductive layer 52a is charged at 53a exposed line-by-line or whole frame at 61a and subjected to a further discharge at 63a, whereby a paper sheet 77a receives an electrostatic latent image which is developed by an electrically biased brush 83a through an electrically biased mesh 87a. The short conveyors 57a, 67a are also electrically biased. In Fig.6 (not shown) imagewise exposure and the second charging step are simultaneous. In Fig. 6a (not shown) imagewise exposure and the first charging step, which utilizes a transparent electrode (106) are simultaneous. In Figs.8, 9 (not shown) the charge sprayed through the endless screen is received by a second endless screen. In Fig.8, further charge is sprayed through this second screen onto a receiver which is then developed. In Fig. 9, charged toner particles are sprayed through the second screen onto a receiver. A radioactive source is mentioned as an alternation to corona discharge devices.

A method of producing high resolution images comprises forming a collimated hole structure 10 defined by a body having a plurality of substantially rectilinear, parallel through passages 12 extending between spaced surfaces of the body, the passages having a maximum transverse dimension of under 500 microns and having an aspect ratio of at least 5:1, providing on one of said surfaces a mask 16, Fig. 5, defining an opening 15 of pre-selected shape, said opening exposing a plurality of the passages, and passing radiation through the exposed passages to form a plurality of images corresponding accurately to the cross-sections of said passages. The mask 16 may be plated on to the body or may be formed by exposing and developing a photoresist material. The method may be used in micro-circuitry wherein the images are formed on a radiation-resist layer which is then developed and etched. Desirably the maximum transverse dimension of the passages is under 10 microns. Alternatively the mask may be another collimated hole structure. Also if desired the body 10 may have corresponding masks over body end surfaces. The hole structure comprises a composite formed of a metal matrix and a plurality of substantially rectilinear, parallel filaments formed of a different metal which is leached out to form the passages.

A selection device for a circular or flat machine comprises selectors which pass down a channel 19 which converges to a throat where electromagnetic selection occurs and into a diverging portion whose walls 20, 21 comprise opposing poles of a single permanent magnet. At the throat the selectors are attracted by pole pieces 29, 29' of selectively energised electromagnets 25, 26. The magnetic walls 20, 21 ensure the selected positions of the selectors. In the embodiment shown the selector 12 can be moved to the left so that one arm 9b of a lever 9 controlling the jack position impinges on its step 12a when the spring 11 exerts its influence. In a modification (Fig. 5, not shown) that part (12'b) of the selector moving between the poles is pivoted to the lower part. In an alternative embodiment (Fig. 2, not shown) a tilting jack is pivotally connected to a selector moving between the poles.

In a system with a transmission channel having a bandwidth W and an impulse response including non-zero components at multiples of ¢w, Fig. 1 (part), the binary data d, Fig. 6, to be transmitted and having a bit rate W, is sampled by a bit-rate clock e, the resulting signal f being gated with a ¢-bit-rate clock g. The output h of the gate passes a partial response filter which ensures the impulse response required and outputs two level signal i to the transmission channel. Receiver, Fig. 5 (not shown).-The signal i is fed to a store comprising three stages in series. The first and second stages are fed with clock pulses o and consequently take-up states shown at p and q respectively. The third stage is fed by clock pulses k, and outputs signal r which, once the receiver is synchronized (from A4 onwards), is identical to the data d. Synchronizing.-The signal i is gated with clock signals m from a divider chain. The resulting signal controls a bi-stable circuit which, when synchronism is lost, inserts an additional pulse at the input of the divider chain. To prevent resynchronization on noise pulses the bi-stable can be replaced by a counter.
