Abstract: 1,102,779. Recording and playback. WESTERN ELECTRIC CO. Inc. 27 May, 1965 [5 June, 1964], No. 22516/65. Heading G5R. [Also in Division G1] In an apparatus for analysing complex signals carried on a magnetic tape 101 (Fig. 1) a portion of the tape is fed from a reel 10 to a supply reel 21 via sensing head 12 and periodically stopped on the periphery of a drum 17 and repeatedly scanned, by a head rotating inside the drum. During each rotation at a particular stop, the output signal is modulated by a different frequency, the resulting beat frequency being filtered by a fixed frequency filter, to provide an output corresponding to a particular frequency in the spectrum of the original signal. The selected portion of tape is clamped under tension at each step, it being arranged that the operation of the tensioning system is delayed relative to the clamp at each stop. The tensioning and clamping system is released and the record advanced by a preselected interval after the portion has been analysed in order to select the next contiguous portion of the record. The outputs are successively recorded by a stylus 22 on a record 39 carried on a drum 23 rotated in synchronism with the rotating head. The amplitude of a mark on the record 39 corresponds to the signal amplitude at any particular frequency, the frequency corresponding to the position across the medium, while distance along the medium corresponds to time. A more detailed description of the operating system circuitry is given (see Division G1).

Title: Temperature measuring instrument
IPC: G01K7/30
Filed: 1962-01-02
Abstract: 997,181. Measuring temperature electrically. GENERAL PRECISION Inc. Jan. 2, 1962 [Jan. 9, 1961], No. 101/62. Heading G1N. A temperature measuring instrument comprises a heat sensitive probe 10 which generates voltage peaks of the form shown in Fig. 2, a circuit which compares the amplitude of the peaks with a predetermined voltage V and selects only those peaks exceeding V, and means for counting the frequency of occurrence of such peaks. The signal generated by the probe is applied to an amplifier 28 supplying a pulse height discriminator and shaper 30 which supplies to a counting circuit, square pulses corresponding to the selected peaks. A.D.C. voltage from the counting circuit, proportional to the peak frequency, is applied to a pushpull bridge circuit to unbalance it and cause a current to flow which is proportional to that frequency and is indicated by a meter. It is stated that the absolute temperature is given by the relation where B and C are function of amplifier parameters and N is the number per second of selected voltage peaks. The instrument is calibrated against an accurate thermocouple, using an electronic counter to obtain values of N and hence calculating B and C.

Title: Improvements in metal reinforcements, more particularly for reinforced concrete structures
IPC: E04C5/18
Filed: 1946-01-02
Abstract: 606,288. Reinforcements for concrete. JONES, W. T., and HODGSON, E. S. Jan. 2, 1946, No. 133. [Class 20(iv)] A metal reinforcement for concrete consists of a strip 10 which is bent backwards and forwards upon itself and is provided with holes 13 or open ended slots 14 near the folds to accommodate longitudinal reinforcing rods 12. When holes 13 are provided, the strip, which is closely folded, is threaded on to the rods 12 and then expanded to an extent which determines the spacing of the bars 12. When slots 14, which may be of bayonet form, are provided, the strip is expanded before hooking on the rods 12. The rods 12 may be curved to provide curved reinforcements, e.g.,- for bridges or balconies. The lower parts of the strip may be bent to form feet 11 to support the reinforcement when it is, for example, used in road making. In this case the rods 12 are threaded through straight strips at right angles thereto, which strips support additional rods intermediate the rods 12. In making a pillar or the like. Fig. 5, four strips 10 in box form tie together four rods 12.

Title: Document scanning apparatus
IPC: G06V30/10
Filed: 1970-01-01
Abstract: 1,271,631. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 1 Jan., 1970 [13 Jan., 1969], No. 134/70. Heading G4R. Document-scanning apparatus scans the document with a beam along a plurality of raster lines extending parallel to a line of data printed on the document, and includes calculating means for producing video signals corresponding to the interception of the beam with the line of data and combining the video signals into a single composite signal, analysing means for deriving from the composite signal representations of selected characteristics of an intercepted line of data, and means for storing a representation of the position of each characteristic. During a format pre-scan in a character recognition system using a vidicon or C.R.T. scanner, video from the scanner is gated to an R.C. filter whenever the scan position is within a preselected window as determined by four voltage discriminators. The time constant of the filter equals that requirzd for the beam to make the plurality of parallel scans along the line of data so its output is a single pulse. Respective capacitor stores receive the value of the vertical deflection voltage when the first derivative of this pulse is zero (middle of vertical height of line of data), when the second derivative is zero and the third derivative is negative (top of line of data), and when the second derivative is zero and the third derivative is positive (bottom of line of data). It is mentioned that line skew can be dealt with by comparing the positions of the middle of the vertical height in two halves of the line of data.

Title: Machine tools
IPC: B23C1/02
Filed: 1961-01-03
Abstract: 902,069. Chucks; machine-tool details. NEW BRITAIN MACHINE CO. Jan. 3, 1961 [April 27, 1960], No. 200/61. Class 83 (3). A machine tool having tool and work-carrying members C, D, E, movable lengthwise of the axis of a rotary tool comprises means for stopping the tool in a particular angular position and for depositing it in a rack K under punched or magnetic tape control. The machine includes a reversible electric motor in the base for rotating and feeding the spindle 17, a reversible rapid-traverse motor for the spindle mounted on the spindle head C and separate multi-speed reversible motors for the feed movements of the spindle head C, the saddle D and the table E, all controlled from a pendant G or a tape-control unit H. The tapecontrol causes the tool spindle to be moved successively to pick-up and replace the tools in the rack K and to machine a workpiece W, the machine being stopped with no tools in the spindle. To stop the spindle in the correct angular position to ensure that a key 18, Fig. 2, thereon engages a recess in the tool, a collar 21 on the spindle has a V-groove 22 engageable by a roller 24 on a fluid-operated plunger 26. The plunger is operated by a solenoid controlled by magnet-type proximity switches 40, 42, 41, 43 which also control the stopping of the spindle motor. When the roller 24 is correctly positioned in the groove 22, an arm 50 on the plunger 26 operates a switch to illuminate a visual indicator. The spindle is held in position by a brake N on a drive-shaft 60. The tools are retained in the rack K by spring-pressed detents engaging the tool-shanks. The front portion 71 of the magazine is movable resiliently relatively to the rear fixed portion 70. If the front portion is moved while tools are being picked up or deposited, switches are closed to stop the machine. The draw-bar mechanism for clamping and unclamping each tool is as described in Specification 852,459.

Title: Improvements in or relating to tuning controls for radio receivers
IPC: H03J7/02
Filed: 1937-01-04
Abstract: 488,266. Adjusting wireless apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 4, 1937, No. 214. Convention date, Jan. 3, 1936. Addition to 487,687. [Class 37] The invention relates to a receiver with automatic frequency control and a push button type of rotating dial for manual adjustment of the tuning element as in the parent Specifica,- tion. The circuit system is identical with that of the parent ; the improvement relating to a modified construction of finger-operated tuning dial. This comprises a hollow cylindrical member carrying press-buttons spaced round its periphery exactly as described in the parent Specification. Fig. 6b shows the construction of press-button employed, the button head 96 being normally fixed laterally by two opposed springs 93, 94 separated by a member 90 in which the button shaft slides. The button carries a stop member 87 which projects from the rear face 53 of the tuning dial when the button is depressed, and, on rotation of the dial strikes a switch-stop which arrests the dial in the position at which the station whose call sign is marked on the press button is tuned in. The present invention provides a ready means of adjusting this position by the arrangements shown in Figs. 5 and 7. The member 87 may be engaged in any one of the holes x, ] ... 9 by pulling the button 96 outwards. These holes have their centres at the intersection of the circle 101 and radii two degrees apart, Fig. 7, the switch member 76 and switch 84 are shown in Fig. 5. In the above arrangements the tuning condenser spindle is driven from the dial 53 by a 2: 1 gearing. This may be dispensed with by arranging the tuning condensers to operate effectively over about 320 instead of 180 by giving the rotor vanes a spiral contour. The tuning dial may then be illuminated by a central lamp mounted on a dyed insulating tube inside the hollow condenser spindle, the connections to the lamp being taken through the tube, Figs. 8 and 9 (not shown). Specifications 489,094 and 471,738 are referred to.

Abstract: 733,658. Sewing-machines. REGINA SEWING MACHINE CORPORATION. Jan. 5, 1953 [Feb. 26, 1952], No. 236/53. Class 112. Needles, vibrating laterally. Provision is made for automatic variation of the width of a zig-zag seam, to produce fancy stitching, by a cam the insertion of which disconnects and locks the normal manual device for controlling the width of seam. In the machine shown the needle-vibrating link 8 is actuated by a slotted lever 5 oscillated by a switch-cam 3 on the shaft 1, the link 8 being shiftable along the lever 5 to vary the amplitude of vibration, by a link 11 connecting it to a member 16 rotatably mounted in the standard of the machine and normally connected to a manually-operable member 15 on the face of the standard. A transverse spindle 17, driven by worm-gear from the shaft 1, is adapted to receive a cam 20 which engages a lever 22 pivoted to the frame at 23 and provided with a slot receiving a block 34 carried by the link 11, so that the cam shifts the link longitudinally and thus varies the amplitude of vibration of the needle. A cover for the opening in the standard through which the cam is inserted is pivoted at 32 and carries a pin 33 which moves in the path shown chain-dotted and engages the lever 22 to lift it to its highest position when the cover is opened. When the cam is placed on the spindle 17, it engages one end of a resilient member 26 and displaces it to move the other end into a notch in disc 13, inside the standard, rigid with the control member 15, so that the latter is locked; an intermediate part of the member 26 releases the engagement between the member 16 and the control member 15, 13, so that the former member is free to move with the link 11, being cut away to avoid contact with the end of the member 26.

Title: Improvements in signalling or indicating apparatus
IPC: G01D5/20
Filed: 1937-01-07
Abstract: 488,498. Electric signalling systems. BARTON, H. W. Jan. 7, 1937, No. 494. [Class 40 (i)] The extent of movement of a primary member is signalled by a characteristic number of impulses generated by a secondary member which follows the primary member with delayed movement at a predetermined constant speed. As shown in Fig. I, a primary member 5 is connected by a spring 6 to a secondary member comprising a piston 7 operating in a cylinder 8. When the member 5 is moved the piston 7 follows up the movement with a delay caused by the gradual leakage of air into the vacuum produced behind the piston. The piston or cylinder may be formed with surface grooves to permit air leakage or a valve-controlled duct may be provided in the body of the piston. A contact 16 on the piston rod 18 co-operates with a plurality of contacts 17 in the circuit of a bell or lamp to produce a number of responses indicative of the extent of movement of the primary member 5. A valve 23 is provided to allow for the quick release of the leakage air when the piston 7 restores to normal. In a modification, the cylinder is arranged vertically, the piston following the member 5 under the action of gravity. In further modifications, a liquid or gaseous medium may be used instead of air and the follow up action may be controlled by compressing a medium instead of by the leakage of a medium into a vacuum. The cylinder 8 may be fixed or movable against spring or weight control when the force tending to make the piston follow the primary member exceeds a predetermined value. The spring 6 may be replaced by a rubber or like member.
