Title: Improvements in or relating to apparatus for continuously perforating webs
IPC: B26F1/08
Filed: 1954-12-07
Abstract: 746,738. Perforating-apparatus. DU PONT DE NEMOURS & CO., E. I. Dec. 7, 1954 [March 26, 1954], No. 35450/54. Class 31 (2). In apparatus for continuously perforating a web comprising a plurality of dies and movable coacting perforators, the web is supported by a wheel which lies eccentrically within a ring, the wheel and ring being rotatably driven at the same speed in the same direction, the perforators and dies being carried around with the ring and wheel and being moved into engagement to perforate the web by relative radial movement of the wheel and ring. In the form shown, both side edges of a photographic film 72 are perforated simultaneously by means of apparatus comprising an assembly of perforators 67 and dies 36 spaced circumferentially around, and carried by, a wheel 29 which is journalled eccentrically on a shaft 5. The perforators and dies are surrounded by cam rings 25, 25<SP>1</SP> mounted concentrically on the shaft 5 and each secured to a rotatable bush 19 journalled on the shaft 5. The wheel 29 is rotated from the bushes 19 by means of loose couplings. Each perforator 67 is supported from its associated base 52 by means of a spring metal member 68 and, during rotation of the wheel 29 and cam rings, is moved to engage the die 36 by means of one of the cam rings engaging a leaf spring 69 also carried by the base 52. The wheel 29 may be concentrically mounted and the cam rings eccentrically mounted. The film is bowed slightly before being fed into, and after being withdrawn from, the punching zone by means of pairs of peripherally grooved idling rollers 74. The punched-out portions of the film are removed by means of a pneumatic jet or by suction (e.g. through openings 36, 32, 38, 6), or by both means. The shaft 5 may be vertical or inclined. If it is desired to perforate only one side edge of the film, only one cam ring is provided. In a modification, Figs. 6 to 8 (not shown), each cam ring is formed with a bead which is received in a recess in each of the perforators, the bead moving the perforator towards and away from the associated die on rotation of the wheel and cam ring(s). In this modification, the bowing rollers may be omitted.

Abstract: 1,012,070. Constant tension winches. GENERAL ELECTRIC CO. Ltd. Aug. 21, 1964 [Sept. 11, 1963], No. 35857/63. Heading B8B. [Also in Division F2] A constant tension winch arrangement comprising a winch drum 1 and cable, a casing 5 for input and output shafts 4, 6 in the form of a differential gear, an hydraulic system including an hydraulic motor 7 coupled via spur gears 8 to the input shaft 4, an hydraulic pump 9 coupled via spur gears 10 to the casing 5 and the winch drum 1 being coupled via clutch 12 and spur gears 11, 2 to the output shaft 6, the arrangement being such that when the winch cable is loaded the motor 7 provides a constant torque to the drum 1 and any power in excess of that required to rotate the drum 1 is used to drive the pump 9 via casing 5 due to the differential gear action of the casing 5 and shafts 4, 6. The clutch 12 is selectively disengaged by an hydraulic ram 13 overriding the springs 25. A two-way valve 24 which in one position sup-  plies high pressure fluid to the ram 13 and in the other position exhausts the fluid into a sump return line 27 is mechanically coupled to a gate valve 28 to prevent operation of the motor 7 when the clutch is disengaged. A plurality of these differential drive units 3 are mounted around the winch drum spur gear 2 for engagement therewith and are all coupled with a common hydraulic system. The hydraulic system comprises a low pressure circuit (relatively thin lines) coupled to a low pressure accumulator 15 and a high pressure circuit (relative thick lines) coupled to a high pressure accumulator 18. A pump 31 is provided between the two circuits to make good any pressure losses. The motor 7 is connected in the high pressure circuit downstream of a flow control valve 23 and non-return valve 22, the motor exhaust is coupled with the low pressure circuit. The pump 9 has its inlet connected in the low pressure circuit downstream of a non- return valve 17 and has its outlet of high pressure coupled via a non-return valve 19 and pressure relief valve 20 to the ram 13. Fluid seepage from the motor 7, pump 9 and valve 24 when the clutch is engaged is exhausted via the line 27 to a reservoir 26. A modified hydraulic system A for the differential unit 3 incorporates a two-way valve 33 which permits high pressure fluid to be fed to the motor 7 for driving in either direction. For rapid drive of the drum 1 a gate valve 35 is provided to allow arrest of the pump 9 and hence casing 5. A pressurereducing valve 32 is also inserted upstream of the motor 7 to allow variation of the torque output therefrom.

Title: Doppler effect speed measuring apparatus
IPC: A61B8/06
Filed: 1974-08-16
Abstract: 1472938 Doppler effect speed measurement SIEMENS AG 16 Aug 1974 [16 Aug 1973] 36290/74 Heading G1G The speed of a mass is measured by Dopplereffect apparatus in which two transducers transmit ultrasonic energy over parallel paths to the mass and each receive the reflected energy, the difference between the transmitted and received frequencies is determined, and the difference between the time taken for the energy to pass from one transucer to the mass and back again and the time taken for the energy to pass from the other transducer to the mass and back again is measured. The Fig. 1 embodiment measures blood flow in duct 8, using pulsed transmission by transducers 3, 4. The time difference measurement enables the duct orientation relative to the transducers to be determined and is indicated or used to compute a correction factor by which the mean Doppler frequency is multiplied automatically to allow for the orientation and so provide a true speed measure. If both transducers are pulsed simultaneously the interval between the arrival instants of the respective echo signals provides the required time difference measurement. In view of the sloping leading edge of the echo signal, a point 9, 10, Fig. 2, half-way up the edge is chosen to define the arrival instant. The apparatus includes two servo loops (one for each acoustic path) which sample the echo intensity in respective brief time gates and, by comparing the sampled intensity with the peak or mean echo intensity, automatically centre the gates about the respective half-way points of the two echo signals. A timer then measures the interval between the starts of the gates. From this interval, and knowing the transducer spacing and acoustic velocity, the correction factor is computed. The mean Doppler frequency is derived by demodulation and processing of the signal at one of the transducers, then multiplied by the correction factor. In a modification the time difference measurement is done by separately measuring the echo times for the two acoustic paths and subtracting one time from the other.

Title: Improvements in or relating to devices for stabilising the oscillation frequency of a mechanical oscillator
IPC: G04B17/20
Filed: 1966-08-12
Abstract: 1,142,676. Clocks and watches. FABRIQUES MOVADO S.A. Aug. 12, 1966 [Aug. 12, 1965], No.36315/66. Heading G3T. A mechanical oscillator has two oscillable arms 7, 8 on which magnets are mounted for stabilizing the frequency of oscillation of the oscillator. As shown, the magnets 3, 3' and 4, 4' are mounted in U- shaped wings 5, 6 of the arms. The arms are supported on springs 10, 11 and oscillate in phase opposition about a pivot ring 12. The springs are anchored at 10b, 11b. By arranging the magnets so that like poles face each other, a decrease in frequency which occurs with increasing amplitude of oscillation is compensated whilst if the magnets have opposite poles facing each other an increase in frequency with increase in amplitude of oscillation is compensated. The frequency of oscillation of a tuning fork may be similarly stabilized by fixing a magnet to each tine of the tuning fork, the magnets being positioned on the facing edges of the tines.
