Title: Improved electromechanical system for measuring angles
IPC: G01C1/06
Filed: 1960-02-17
Abstract: 915,976. Dividing engines. VYZKUMNY USTAV OBRABECICH STROJU A OBRABENI PRAHA. Feb. 17, 1960 [Feb. 24, 1959], No. 5677/60. Class 97 (3). [Also in Groups XXXVIII and XL (b)] The outputs of four stators coacting with a constantly rotating drum to produce 4 voltages of different frequency are used to obtain an accurate measure of the angular displacement of one of the heads, fixed to a rotatable table, relative to a second fixed head. The four signals of different frequency may be obtained by magnetic recording, optical recording, or by use of multipole generators. As shown in Fig. 1, head hm is attached to the rotatable table 2 and coacts with recorded track zm on drum 1 to produce a signal of 360 cycles per rev. of the drum 1. Head hp is fixed and produces a signal of 381 cycles per rev. of the drum, while head hkl and hk2 are mechanically linked but together rotatable around the drum relative to both heads hm and hp and coact with tracks zkl and zk2 to produce signals of frequencies 380 and 361 cycles per rev. of drum 1, respectively. The drum is rotated at 10 revolutions per second, the output signals from the heads fed to modulators 3 and 4 to form difference frequencies f<SP>1</SP> (=fm - fk1) and f2 (= fp - fk1). The phase difference between these two difference frequencies is then dependent on the relative positions of the heads, one complete revolution of heads hkl and hk2 being equivalent to 1 degree movement of the table and head hm. The position of the table may be determined by reading on scale sm the whole number of degrees movement of the table adjusting the position of heads hk1 and hk2 until the phase meter reads zero when the fraction of a complete revolution of heads hk1 and hk2, read off on scale sk, will indicate the fraction of a degree movement of the table and head hm. Multipole generators.-The signals may be generated by toothed rotors and stators having the appropriate number of coacting teeth, and a modification is shown in Fig. 3 in which the modulator is dispensed with by utilizing a split stator one half of which, 9, has, say, 360 teeth and the other half, 10, having 381 teeth cooperating with a rotor 11 having corresponding numbers of teeth, the output signal of stator 12 will then after rectification and filtering, correspond to the difference signal which can be applied, together with a signal from a similar generator having 361 and 380 teeth, direct to the phase meter.

Title: An improved method of imparting angular motion to a beam of light for scanning purposes for television and the like
IPC: H04N3/10
Filed: 1936-02-26
Abstract: 471,066. Television. SCOPHONY, Ltd., and WIKKENHAUSER, G. Feb. 26, 1936, No. 5686. [Class 40 (iii)] A beam of light is passed through a medium 2 in which are set up supersonic mechanical waves ; the medium acts as a diffraction grating and the emergent light consists of a central beam, focused at 6, flanked by beams, focused at 7, 8, corresponding to spectra ; the beam 8 will normally be very weak and may be neglected ; a shutter 9 cuts off the central beam and those beams on one side of it ; the frequency of the supersonic waves is varied to vary the deviation of the side beams so that the beam 7 executes a linear movement, which is used as one component of scanning. The supersonic waves are generated by a piezo-electric crystal 3 and their frequency is varied in accordance with a saw-tooth wave form. The oscillating beam may be passed through a train of prisms to increase its angular deviation.

Title: Improvements in powder catapults
IPC: B64F1/06
Filed: 1939-02-21
Abstract: 525,476. Launching apparatus. SCHNEIDER & CIE., and FIEUX, J. Feb. 21, 1939, No. 5822. Convention date, Sept. 13, 1938. [Class 4] In launching apparatus in which a piston 15 in a cylinder 40 is driven in a manner similar to that in which a projectile is-driven in a gun by the employment of combustion gases of gunpowder or other explosive products or mixtures, the combustion chamber is subdivided into two distinct chambers connected in series, with an adjustable, regulating pressure-reducing device 26 interposed between them. As shown, a catapult includes chambers 4, 14. A charge or cartridge 22 is adapted to be exploded in a chamber 1. The regulator 26 has a collar 27 adapted to fit an orifice 24 and when the pressure in the chamber 14 has risen to such a value that its action on the lower surface of the collar 27 overcomes the action of the spring 30, the regulator 26 is forced up and the collar clears the orifice 24, causing the pressure to fall due to the forcing out of the piston 15 which is connected to the launching carriage by cables and pulleys. When the carriage reaches the end of its stroke the momentum tends to cause reversal of the movement of the piston which increases the pressure in the chamber 14 and raises the regulator 26 to uncover an exhaust port 35. Movement of the regulator 26 is damped by a dash-pot 37.

Abstract: 728,321. Pit props. REGIE DES MINES DE LA SARRE. March 3, 1953 [March 10, 1952], No. 5921/53. Class 20 (2). A telescopic pit prop consists of a punch 6 extendable from a barrel 1, a lock 2 rigidly secured to the barrel 1, locking wedges 9, 21 in the lock and a wedge 22 disposed transversely between the wedge 21 and the lock. Clamping members 17, 20 which have friction linings 19 are disposed between the wedges 9, 21 and opposed faces of the punch 6. To operate the lock the wedge 21 is driven upwards and is locked by driving in the wedge 22 and the wedge 9 is then driven in. The wedge 9 has a small angle and so exerts a large clamping force. To release the lock the wedge 22 is loosened by a series of gentle taps so that the wedge 21 allows the punch 6 to slip slowly under roof pressure.  When the loosening of the lock is complete the wedge 9 is returned to its inoperative position by a compression spring which acts between the wedge 9 and the lock. In two modifications the wedge 21 is inserted horizontally into the lock and the wedge 22 is arranged in alternative transversely disposed positions.
