Title: Improvements in or relating to vertical grinding machines
IPC: B24B7/08
Filed: 1939-07-27
Abstract: 531,584. Grinding machines. WRIGHT ELECTRIC MOTORS (HALIFAX), Ltd., and WRIGHT, H. H. July 27, 1939, No. 21801. [Class 60] [Also in Group XXVIII] In a vertical grinding machine of the kind having an annular grinding wheel h on the upper end of the spindle c of an electric motor and rotating in the opening j<SP>2</SP> in a vertically adjustable work table j, the work table or a part connected therewith rests on a nut member i working on an externally-threaded portion a<SP>1</SP> of the bar member a carrying the motor. The nut is provided with a series of balls i<SP>3</SP> held in position by screws i<SP>4</SP> and a ball or roller bearing may be provided between the nut and the sleeve j<SP>1</SP> projecting from the table. The upper end of the bar a is closed by a domed plate f<SP>1</SP> provided with a sealing device n of felt &c. to prevent dust forming between the abutting surfaces of the sleeve j<SP>1</SP> and the base a. The sleeve j<SP>1</SP> has a lug a<SP>2</SP> and the nut and flange i<SP>5</SP> for a similar purpose. The spindle c rotates between a roller bearing f and a combined radial and thrust bearing e. The grinding wheel has an annular lug h<SP>1</SP> by which it is secured by a plate h<SP>2</SP> to a plate g on the spindle c. The space within the grinding wheel is filled by a central work support k carried by a bridge member k' secured to the work table, the inner face k<SP>2</SP> of the bridge forming a chord across the table and serving as a work guide. The bridge has openings k3 through which the dust produced during grinding may be drawn. In the form shown the member k<SP>1</SP> communicates by a duct m with a chamber m<SP>1</SP> containing a fan m <SP>2</SP> driven by an electric motor m<SP>3</SP> and having an outlet over which is secured an air porous bag and filter. The motors may be started or stopped simultaneously. The fan may alternatively be carried by the plate g and the work table provided with openings so that the space between the plate g and plate f<SP>1</SP> forms the dust chamber which communicates with a dust receptacle and filter. In another form the air stream may carry the dust away through a pipe to an outlet open to the atmosphere.

Title: Method of transmitting information within a continuous wave train by means of a serial code
IPC: G01S13/76
Filed: 1963-05-31
Abstract: 1,039,174. Data transmission; radar. STANDARD TELEPHONES & CABLES Ltd. May 31, 1963 [June 7, 1962], No. 21857/63. Headings H4D and H4P. Serial data is transmitted by blanking halfcycles of a continuous wave train. In the case of binary data, a Space is indicated by the unblanked wavetrain or by blanking the negative-going half-cycle of a cycle, and a Mark by blanking the positive going half-cycle. For ternary data the three conditions are respectively indicated by a blanked positive-going half-cycle, a blanked negative-going half-cycle, and an unblanked negative- or positive-going half - cycle. The data - modulated wavetrain amplitude modulates a carrier for radio transmission. As applied to radar-interrogator technique, the pulse radiated from the interrogator is modulated by data as described above. The responder derives the carrier wave from the received pulse and modulates this with other data, transmitting the resultant modulated pulse. A coarse distance measurement is obtained by measuring the time difference between the leading edges of radiated and received pulses, and a fine measurement by comparing the phase of the modulating waveforms.

Title: Improvements in and relating to apparatus for recording the speed of working of machine or other revolving shafts
IPC: G01P1/12
Filed: 1931-07-31
Abstract: 382,664. Recording-apparatus. TOLNAI, G. K., 13, Ivester U., and HER. MANN, P., 45, Buda÷rsi Ut., both in Budapest. July 31, 1931, No. 21869. [Class 106 (iv).] An apparatus for recording the speed or working of a machine comprises a recording member periodically restored to and started anew from a definite position under the control of the machine, the recording member being driven from a constant speed shaft through the intermediary of a cam surface. In the form shown a shaft 1, driven by the machine under observation, operates a pair of contacts 5, 6 in circuit with a battery B and electromagnet M<1>. The magnet M<1> when energized withdraws a locking pawl 7 from a projection 73 on a disc 10 frictionally mounted on a constantly rotating shaft 9 thereby allowing the disc to rotate. The disc is made of insulating material and carries segmental contacts 11, 111 adapted to co-operate with brushes 112, 113, 114 in circuit with a battery C and electromagnet M<2> .. M<5>. When the pawl 7 is withdrawn it closes a circuit through contact 8, battery C, brushes 112, 113, contact plate 11, and electromagnets M<2>, M3, M4. The magnet M<2> serves as a holding magnet for the pawl 7. The magnet M<3> co-operates with an armature 20 guided in blocks 201, 202 and through which passes a spindle 14 that is tilted when the magnet is excited to disengage a worm wheel 13 frictionally mounted thereon from a worm 12 on the shaft 9. The magnet M<4> controls a clutch lever 24 adapted to couple the clutch part 22 to the shaft 9 during the time the worm gearing is disconnected. The shaft 14 carries a cvlindrical drum 15 on which is mounted a spiral curve 16 with which cooperates a roller 18 on a rod 17 carrying a marking member 171 adapted to engage a clock-driven record surface 26. When the worm gearing on the spindle 14 is freed a spring 19 surrounding the spindle rotates it in the direction of the arrow 151 until a stop 281 is engaged by a locking arm 28. Simultaneously therewith the rod 17 which is suspended by a cord 173 passing over a pulley 25 and attached to the clutch part 22 is raised to its starting position. As soon as the circuit is broken at the bushes 112, 113 the locking pawl is returned to locking position, the worm gearing is engaged, and the rod is lowered until the roller meets the part 16<1> of the cam surface. A circuit is thereafter completed through the contact 111, and brush 114 to energize the magnet M<5> so as to free the stop 281 whereupon the cylinder 15 is rotated in the direction of the arrow 152 and the marking member 171 is displaced an amount which is inversely proportional to the time.

[Also in Group XXXVI] For generating the first time derivative of a signal (e.g. a control signal) amplitude modulated on a carrier frequency, the input at 1, 2 is connected over capacitance C 1  in series with resistance R 2  to fixed contact k 1  of a vibrator operating at the frequency and phase of the carrier, whose fixed contact k 2  is connected to the output across resistance R 1 . The vibrator moving contact p oscillating between k 1 , k 2  is grounded over capacitance C 2  and on alternate half cycles charges C 2  from the instantaneous amplitude of the modulated input in series with C 1  and R 2 , and on the remaining half cycles discharges into R 1  to develop there-across a train of rectangular pulses at carrier frequency whose amplitude envelope represents the first derivative of the input modulation envelope. In a modification (Fig. 2 not shown) the mechanical switching vibrator is replaced by a switching rectifier bridge controlled by a reference voltage at the carrier phase and frequency. The device is stated to operate on a D.C. input, and a mathematical analysis is given.
