Title: Improvements in or relating to devices for cutting into pieces a thin continuous strip
IPC: B26D7/20
Filed: 1935-03-19
Abstract: 440,694. Cutting webs of paper. FROMAGERIE LE CASTEL SOC. ANON., 29, Rue Peillonnex, ChÛne-Bourg, near Geneva, Switzerland. March 19, 1935, No. 8597. Convention date, March 19, 1934.

Patent GB-850198-A (GB)
Title: Visual omnidirectional range station monitor
IPC: G01S1/02
Filed: 1959-03-12
Abstract: 850,198. Radio navigation. BENDIX CORPORATION. March 12, 1959 [March 19, 1958], No. 8634/59. Class 40(7). [Also in Group XXXV] The invention relates to a monitor for detecting the zone of ambiguity over a visual omnidirectional range (VOR) radio beacon and capable of taking appropriate action. If the receiver being monitored is in use to provide control signals for an autopilot the monitor may serve to disconnect the receiver for a predetermined time on entry into the zone of ambiguity and to substitute a preset course signal. Cross-wind compensation may be achieved during this time by maintaining the control system integrator output. The time for which the receiver is disconnected may be fixed or dependant on such flight parameters as height and speed to ensure that sufficient time is allowed for the craft to traverse the zone of ambiguity before normal control by the receiver is restored. The monitor makes use of the signals fed to the To-From flag indicator and in the embodiment described these are fed at 101, 103 to a modulator 104 energized from an A.C. source 105. The modulator output is fed through a two-stage transistor amplifier 107, 111 to a demodulating circuit providing an output across resistors 125, 127 which are centre-tapped to earth. A rectifier bridge 129 converts the output to one of fixed polarity which is applied to the winding 131 of saturable reactor 134. The bias supplied to the reactor winding 133 is such that the core is saturated and current can flow in control windings 135, 137 to control timing and switch circuit 9. The presence of an adequate input, regardless of polarity, causes sufficient current flow through winding 131 to oppose the core flux induced by winding 133 to the extent of unsaturating the core. Negligible current from A.C. source 105 therefore flows in the windings 135, 137 and the relays in the control circuit are in their normal condition allowing receiver signals to be passed to the utilization circuit. When the craft enters the zone of ambiguity the amplitude of the input at 101, 103 drops and allows current to pass through windings 135, 137 to operate the control circuit relays, one (149-151) of which is self-holding for the duration of the predetermined time interval.

Title: Apparatus for producing beams of ions of a given element
Inventor: BARNAS RENE
IPC: H01J27/02
Filed: 1956-03-20
Abstract: 829,783. Ion sources. COMMISSARIAT A. L'ENERGIE ATOMIQUE, and CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 20, 1956 [March 26, 1955], No. 8717/56. Class 39(1). In an ion source comprising a probe electrode composed of the element from which the ions are to be produced or an alloy or compound thereof, a plasma of ions is formed in the vicinity of the electrode and the ions are ejected from the electrode by a sputtering process in which the electrode is bombarded by positive ions of the plasma, the electrode being charged negatively with respect to the plasma. The plasma is formed in a suitable gas e.g. a rare-gas, chlorine, nitrogen or the vapour of the element of which the electrode is made, and may be produced by a beam of electrons on a H.F. discharge. In Fig. 1 the electron beam produced by cathode 2 and anode 3 is confined by an axial magnetic field H. The probe electrode 4 within a casing 1 may be replaced by a graphite cylinder provided with a lining of the element to :be disintegrated or may be in the solid or liquid state and may be a conductor or semi-conductor or made of insulating material. Specific elements mentioned are molybdenum, palladium, iron and copper. In Fig. 6 a H.F. discharge is produced by a coil 17 within a cylinder 11 containing a sheet 12 of the element to be disintegrated. The ion source is suitable for ion accelerators or electro-magnetic isotope separators.

Title: Electronic flash unit with an automatic exposure control
IPC: H05B41/32
Filed: 1975-03-04
Abstract: 1479844 Supply systems for flash tubes FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 4 March 1975 [9 April 1974] 8972/75 Heading H2H [Also in Division G2] An electronic flash unit has a light sensing circuit 24, 25, 19, 20, 21 which, on receipt of a predetermined quantity of light, turns on a quenching thyristor 10 so that a quenching capacitor 9, which has charged through a resistor 11, discharges to turn off a switching thyristor 4 and thereby turn off the flash tube 3; the unit including means for turning quenching thyristor 10 off again so that the unit is quickly readied for re-use. As shown in Fig. 1, on closing a synch, contact 7 an ignition circuit 5, 6 turns on tube 3. Light reflected from the object is detected by a phototransistor 24 and integrated by a capacitor 25 which eventually turns on a thyristor 19. This (a) discharges a capacitor 20 to turn on quenching thyristor 10 whereby capacitor 9 discharges to turn off switching thyristor 4. Capacitor 9 then charges to the opposite polarity through tube 3 and thyristor 10 before tube 3 is finally extinguished, (b) turns on a transistor 33 so that a capacitor 43 charges and then is discharged by a unijunction transistor 40 to turn thyristor 4 on again. This discharges capacitor 9 to turn off quenching thyristor 10. When capacitor 9 has recharged through resistor 11 the unit is ready for use again. The unit may be used with a cine camera for making a plurality of flashes for each frame so that the illumination appears continuous to the human eye, or with a still camera for making a plurality of exposures on a single frame e.g. to demonstrate movement patterns. As shown in Fig. 2, closing a camera synch. contact 63 triggers a monostable circuit 65 and while circuit 65 is in its unstable state, a generator 64 produces pulses each of which turns on a thyristor 90 connected between points A and B of Fig. 1. Thus for each frame, the circuit of Fig. 1 makes a number of flashes, each photo-electrically timed. Fig. 3 (not shown) shows a cine camera having a motor-driven rotary shutter (48) coupled to a cam disc (51) having cams (52a, 52b) for operating a synch. contact (53).

The corrugations may be discontinuous or helical; The crushing may be achieved by using forceps (Fig. 2, not shown) or as shown by two collars 18 which are brought together by screw and nut assemblies. The collars 18 are helical in form so that they can be screwed on to the helical corrugations. The split in the collars tends to close as the collars are drawn together thus tugging a corrugation between the end 26 of the collar forming the split (Figs. 7, 9 not shown). The piece of corrugated tubing may be provided at the end of a plain piece of tubing (Fig. 4 not shown) or at an intermediate portion thereof.
