Title: Error-correcting data transmission system
IPC: H04L1/00
Filed: 1972-05-15
Abstract: 1349815 Digital transmission; error correction PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 May 1972 [18 May 1971] 22603/72 Heading H4P Improvement of a known error correcting system utilizing two time spaced channels can be effected by replacing fixed switch-over procedure by one adapted to the nature of errors, particularly error burst length. In the known system bits from source 100 are passed directly through channel R also through delay register 105 and mod (2) adder 107 also receiving an input from linear decoder network 106, the resultant being passed through channel I2 which may be time multiplexed with I1. At the receiver 102 channel I1 is passed through delay register 108 to contact A of switch 111 and channel I2 through mod (2) adder 110 also receiving an input from linear decoder network 109, to contact B. A further mod (2) adder 112  produces syndrome digits which control switch 111. Delay registers 105, 108 have the same delay of N digits hence a disturbance on path 104 appears at B contacts N digits before appearance on A hence by appropriately switching 111, which in prior art is actuated according to a determined procedure, disturbance can be eliminated from receiver 103. The improvement is based on an assumption that the minimum distance between two error bursts is smaller than with determined switch over period if the burst is less than N-21. The output from adder 112 is fed to a syndrome analyser 200 which distinguishes between single errors on either channel and error bursts. A signal at the begining and end of error bursts is given on lines 202, 203 respectively and in the absence of such signals a return line 204 provides one input to an AND gate (408, Fig. 4, not shown) the output from which is connected to a mod 2 gate (400) and through delay inverter (409) to reset input (402) of syndrome register (401), this being connected to pattern register (403). Mathematical treatment regarding the development of polynomes governing the conditions and logic circuitry for performing the operations is given in the Specification.

Title: Improvements in or relating to attachments for use in contour and taper turning on lathes
IPC: B23B3/18
Filed: 1951-10-04
Abstract: 691,660. Turning. LAYTON, D. A. and ROGERS, W. E. Oct. 4, 1951, No. 23161/51. Class 83 (iii). A contour and taper turning device for lathes comprises a main bracket, a tool-holding block pivotally carried thereon, a tracer pin secured on the block, a tracer bar rotatably mounted about its longitudinal axis and link means to turn the bar during a machining operation for automatically controlling the angular relationship between the operative edge of the bar and the tracer pin, so that on displacement of the attachment along a lathe bed, a tool carried in the block produces a profile on the work determined by the contour of the operative edge of the tracer bar. A main bracket has a face plate 1 separated by an undercut recess 3, Fig. 3, from an integral rear plate 2. The latter has bolt holes 4 for attachment to a turret. Apertures 5, 6 are provided in the face plate and rear plate, respectively, for the passage of the work, and a tool-carrying block 13 is pivotally mounted on the front face of the face plate 1 by a stub shaft 14. A tool 22 carried in the block overlies the apertures 5, 6 and moves in correspondence with the contoured edge of a tracer bar 11 against which an adjustable tracer pin 12, also carried in the block, is pressed by a spring 18. The bar 11 is held against longitudinal movement during turning and is relatively slidable in a rotatable bush 10 secured in the main bracket. This bush is connected by linkwork 25-28 with the block 13 and as the latter rotates under the influence of the tracer mechanism this rotation is transmitted back to the bush and tracer bar to maintain the latter at right angles to the tracer pin 12. Alternatively the linkwork may be disconnected from the block 13 and controlled by a camshaft driven by the lathe when profiled work of irregular diameter is produced. Rests.-Two bolt-holes 7 are provided in the face plate for a work rest. This may take the form of a bracket with an antifriction bearing 34 and sleeve 33 for supporting the work, and the sleeve may be shaped to suit non-round work. A bracket 35, Fig. 4, with a further tool 38 for sizing the work and a hard-metal part-round supporting bush 36 may be employed. In a further modified form the bracket may support a pair of conventional adjustable steady members. When work such as a casting which cannot be supported in a bush is to be operated upon a steady bracket with an extension arm to engage an overhead pilot bar is used.

Title: Improvements in operating devices for broadcast receiving sets
IPC: A47G9/02
Filed: 1932-08-18
Abstract: 405,716. Adjusting wireless apparatus. FREYTAG, E., 2, Schlossgrabenweg, Zwickau, HAYN, F., Erfenschlag, near Chemnitz, and MUNCH, A., 8, Agricolastrasse, Chemnitz, both in Germany. Aug. 18, 1932, No. 23171. Convention date, June 3. [Class 37.] A broadcast receiving set has a series of push-pins adjustable in effective length to calibrate them for different wavelengths so that when any pin is pushed in to its full extent the rotor of a condenser assembly is directly moved to tune the set to the wanted station. Fig. 4 shows one such push-pin which comprises a sleeve 14 movable in a panel 7 and a bracket 7a thereon against a spring 11 until a hook 10 on the sleeve engages a projection 12 on a detent 8. The projection 12 extends for the whole length of the row of push-pins so that the pushing in of any pin releases any previously depressed pin. Each sleeve 14 has a button 15 connected to an internally screwed sleeve 16 whch engages a threaded pin 17 prevented from rotating relatively to the sleeve by a pin 20 passing through a slot 21 in the sleeve so that rotation of the button varies the amount of projection of the pin 17 beyond the sleeve. The pin 20 also engages a slotted plate 22 to prevent rotation of the sleeve. A locking device is provided to prevent accidental rotation of the button once it has been adjusted to suit local conditions. A modified construction of pin has the hook 10 formed as a groove so that the pin can be readily withdrawn through the panel when a flat restoring spring, similar to the spring 25, Fig. 12, is removed. When any sleeve is depressed the flat end of its pin 17 engages a round bar on the rotor of a condenser to move its plates into the stator to the required amount against a spring tending to withdraw the rotor. Fig. 12 shows a modification in which a wedge 42 is inserted between the pin 17 and the bar on the condenser assembly, the wedge being vertically movable by a screw 43 to vary the adjustment. A modified returning spring 25 also is shown which has a forked end engaging flats 28 on the member 14 to prevent the member from rotating. Where necessary a projection on the push-pin engages a wave change switch during its stroke. Fig. 14 shows push-pins 15, 151 set vertically, and these pins may be arranged in more than one row at different levels and in staggered formation. Each spindle 17 screws into a sleeve provided with a groove engaged by a projection to prevent rotation and a spring detent 38 engages a toothed boss 40 on the pin 17 to prevent accidental rotation of the pin 17 after adjustment. The detents 8 for the two rows are interconnected so that depression of a pin releases any previously depressed pin in either row. In this modification the ends of the pins 17 are rounded and engage flat surfaces f connected to the rotor assembly.

An illuminated push-button switch comprises two identical body parts 1 held together by an outer casing 54 and two rivets 45 which also pass through two micro-switches 41. The parts 1 form a large recess 40 in which the switches 41 and a resilient actuator strip 48 are located, and at their forward ends have recesses accommodating lamps 39 whose connecting elements 21, 22 extend to the rear and form terminals adjacent terminals 43 of the switches 41. Shallow recesses on the mating faces of the forward ends of the body parts 1 (Figs. 5 and 6, not shown) form a slot, in which a plate member 27 is longitudinally slidable, and a cylindrical hole in which a spring 29 is seated. The spring 29 lies in a cut-out 28 in member 27 and urges it outwards. A push-button 37 fits on to the protruding end 33 of member 27 and is removable for access to lamps 39. The member 27 has a bent-up lug 46 at its inner end which engages the actuator 48 and also extends through a slot in the casing to be engaged by known latching means (not shown). A plurality of switches may be assembled with a common latching means (Figs. 13 and 14, not shown) such that depression of any one button releases a previously latched switch, or a special release button may be provided. In the further embodiment of Fig. 16 a ratchet-wheel 65 is moved one tooth by a spring-loaded pawl 71 each time the end 33 is depressed and this revolves a square-section rotor 64 by 45 degrees. Successive actuations thus result in the switches 41 being alternately held open (when a flat on rotor 64 seats as shown) and held closed (when an edge of rotor 64 seats in notch 78).
