Title: Improvements in or relating to stylographic pens
IPC: B43K8/16
Filed: 1920-06-21
Abstract: 165,654. Dalzell, H. D. June 21, 1920. Reservoir pens.-In a stylographic pen of the kind in which the point-section 1 has an annular air chamber 3 in communication with the air and the ink reservoir, a short hollow sleeve 11 carries an elastic sac 10 for filling purposes and fits into the barrel 14 of the pen so that the sac, sleeve and point-section form a complete ink-carrying unit, the point-section fitting into the sleeve 11 so as to form the air chamber 3 between the interior of the sleeve and an annular recess 4 in the point-section. A screw-on safety cap 22 is used, having an internal air chamber 21, the face 20 of which contacts with an annular shoulder 19 on the pointsection, the writing-point being received by a rubber pad 25. The air chamber 3 preferably communicates with the air by a longitudinal hole 2, and with the ink-passage 7 by a radial hole 6 at the end of the chamber 3 remote from the writing- point.

Title: Process and arrangement for the production of cables and conductors having a corrugated sheathing
IPC: B21D15/04

Abstract: 762,029. Sheathing cables; corrugating. OSNABRUCKER KUPFERUND DRAHTWERK. June 9, 1954 [June 29, 1953], No. 16909/54. Classes 83 (2) and 83 (4). [Also in Group V] In a method of corrugating a cable sheath 3, Fig. 4, the length of the troughs 7, Fig. 3, is so arranged that the increase in length resulting from the reduction in diameter is equal to the shortening in the crests 8 so that the sheath has no overall change in length. An extruded sheath 3 containing a core 4 and cooled by a spray 5 is fed over a large diameter draw-off drum 11 directly from the press 1 and passes to a corrugating tool 9 before winding on a drum 10. The corrugating tool 9 is longitudinally movable so that the differences in the corrugating and winding speeds may be taken up and means may be provided so that small movements of the tool 9 control the speeds. In an alternative arrangement the extruded cable may be coiled on a drum and subsequently corrugated. The sheathing may also be formed from sheet metal strips joined by welding &c. and may be of lead, aluminium, copper, titanium or their alloys or of steel or of plastic materials.

Title: Digital code detectors
IPC: H04L1/00
Filed: 1972-04-17
Abstract: 1413671 Digital error correction MARCONI CO Ltd 26 March 1973 [17 April 1972] 17516/72 Heading G4A [Also in Division H4] A digital code detector for recognizing a predetermined code combination includes a feedback register for performing a modulo-2 division on the code. The code represents a polynomial p(x) where p(x) = f(x)+r(x). Polynomial r(x) is the remainder resulting when f(x) is divided by g(x), where g(x) is the polynomial represented by the divider. The divider divides p(x) by g(x) and the resulting remainder digits, which should all be zero, are monitored as they occur to determine whether the code has been correctly received.  The divider described comprises 15 bi-stable stages S and modulo-2 adders (EXCL-OR) G. It represents the polynomial The code to be detected, shown in the column marked INPUT, comprises a 4-bit part f(x) in rows 1-4 and a 16-bit part r(x) in rows 5-20. As the code is shifted in to the divider the first 4 stages are monitored. When f(x) is detected in these stages, i.e. after shift 4, associated circuitry is enabled to monitor the remainder bits which will now appear successively in stage 0. These should be all zero. However if a 1-bit appears an error counter is incremented and the content of stages 0, 5 and 12, i.e. those following an adder G, is complemented. If the number of 1-bits appearing in the remainder exceeds a preset value the received code is regarded as faulty. If the value is not exceeded the code is regarded as correct and may be used as a synchronizing signal.
Patent GB-1139261-A (GB)
Title: Improvements relating to multi-digit counters
IPC: H03K25/00
Filed: 1966-04-21
Abstract: 1,139,261. Electronic predetermined counters. GENERAL TIME CORP. 21 April, 1966 [10 May, 1965], No. 17535/66. Headings G4A and G4D. A variable modulus electronic counter comprises a units count module 10 together with two identical adder modules 12, 14, the counter producing a single output when a pre-set number of input pulses have been received. An initial control pulse from a terminating module 108 is applied via a switch 70h to set a flip-flop 40h and thus enable a variable (1 to 9) counter 28h, the same pulse being also applied to reset two other flip-flops 40t, 40u, which respectively control variable counters 28t, 28u, which are then disabled. Initial pulses received from a source 16 are therefore passed via a pulse former 24u and two cascaded decade counters 54t, 54h to variable counter 28h which therefore records " hundreds " of pulses. All the counters used may be of the magnetic cup and bucket type, the variable counters including means to adjust the volt/second content of input pulses applied to their magnetic cores. Transistors are employed in the control circuits. When counter 28h reaches its preselected value, it emits a pulse to reset flip-flop 40h and so disable the " hundreds " counting stage. The same pulse sets flipflop 40t to begin a " tens " count on variable counter 28t, which similarly disables itself upon reaching its preselected value, and enables the " units " counter 28u by setting flip-flop 40u. When the "units" counter reaches its preselected value it applies a pulse to the terminating module 108 which emits a "count completed" pulse on line 109, and also applies a reset current to reset the magnetic cores of all the counters to their " zero " state. The invention may be applied to a liquid-dispensing apparatus (Fig. 3, not shown) in which the amount of liquid to be applied to a container is controlled within rough limiting values by a series of cascaded fixed counters, a final " trim " quantity of liquid being applied under the control of the variable counter whose count value may be changed as the density of the dispensed liquid varies.

Title: A boundary follower
Inventor: KING BRIAN EDMUND
IPC: G06K11/02
Filed: 1964-10-28
Abstract: 1,128,901. Photo-electric edge followers. BRITISH OXYGEN CO. Ltd. Oct. 22, 1965 [Oct. 28, 1964], No. 17648/64. Heading G1A. Apparatus that will follow the boundary between areas of a record which absorb light differently comprises two light sensitive devices mounted a fixed distance apart, means causing relative oscillation between the devices and an image of the boundary, means for combining the outputs of the devices and means responsive to the combined output to steer the apparatus to follow the boundary. As described the cells oscillate in the direction of the line joining them so that they cross the boundary. Their outputs are fed to a difference amplifier to give a sinusoidal signal at twice the scanning frequency when the centre of scan coincides with the boundary. When there is not coincidence a signal at the scanning frequency appears having a phase indicative of the sense of displacement. This signal causes energization of a steering motor. The cells may be mounted on a Piezo-electric crystal as described in Specification 1, 014, 975. The apparatus may be converted to a conventional line follower by disconnecting one of the cells and offsetting the centre of scan either optically or by applying a bias to the Piezo-electric crystal. A mirror directing light on to the cells may be oscillated instead of the cells themselves and an electromagnetic system may replace the Piezoelectric system.

Abstract: 842,919. Determining the frictional properties of yarns. HOSIERY & ALLIED TRADES RESEARCH ASSOCIATION. July 23, 1958 [June 5, 1957], No. 17833/57. Class 106 (2). An apparatus for measuring the frictional properties of yarns and the like comprises a friction pillar 4, means to draw the yarn Y around the pillar at constant speed, means 2 for applying a predetermined tension to the yarn running to the pillar 4 and means 5 for determining the tension of the yarn running from the pillar. The initial tension of the yarn is adjusted by the controller 2 so as to balance a beam 8, as indicated by a pointer 13a. The tension is then equal to half the weight W, with which the beam is loaded. To measure the final tension, a second beam 17, carrying a pulley 19 around which the yarn runs, is balanced by the use of a variable load applied by a chain 22. The tension is then equal to half the weight W 2 , with which the beam is loaded, with the additional load applied by the chain 22. From a knowledge of the initial and final tensions, the frictional force between the yarn and the pillars 4 can be calculated.
