Title: Improvements in or relating to high-frequency heating generators
IPC: H05B6/04
Filed: 1952-09-23
Abstract: 708,796. Transformers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 23, 1952 [Sept. 26, 1951], No. 23835/52. Class 38(2) In a high-frequency heating generator incorporating a discharge tube oscillator, the output transformer comprises a secondary winding 3 of bent metal strip surrounding a primary winding 1 which is in the form of a tube through which passes cooling water which is cut off by an electrically controlled valve 29 when the generator is switched off. Condensation on the winding during non-working periods resulting in flashover is thereby avoided. The supply of cooling water to the tube anode is not affected thereby. The valve 29 of known construction, Fig. 2 (not shown), is opened against a spring by an electromagnet which is energized through a contact of the relay which controls the supply to the tube anode. To cut off the water when the tube fails, the electromagnet may alternatively be operated by a voltage derived from or controlled by the output of the tube. The cooling water is arranged to pass through blocks 5, 7 on ends 3<SP>1</SP>, 3" of the secondary winding 3, to which blocks the heating coil (not shown) is connected. To control the output energy the primary winding 1 is moved axially relative to the secondary winding.

Title: Improvements in local oscillator controlling systems
IPC: H03J7/02
Filed: 1962-06-20
Abstract: 970,750. Automatic frequency control. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. June 20, 1962 [June 29, 1961; Feb. 22, 1962], No. 23849/62. Heading H3A. In a local oscillator control arrangement for obtaining an I.F. signal of constant frequency in a radio link receiver which incorporates a discriminator in which the phase of the incoming signal is compared with that of the local oscillator signal and means for converting the discriminator output signal to a local oscillator correction signal, means are provided in the event of the received signal falling below a threshold value for making the converting means inoperative and for controlling the local oscillator by the last stored correction signal pending increase of the received signal above the threshold value. The signal from local oscillator 6 and the incoming signal on line 1 are supplied to phase discriminator 2 to provide a phase difference signal which is amplified to form one input to an amplitude comparator 411. The local oscillator correction signal supplied from digital-analogue converter 45 is applied as the second input to the comparator and any difference signal is applied to a threshold amplifier 412 which provides an output on either line 12 or 12<SP>1</SP> depending on whether the difference is above a first set value or below a second set value. AND circuits 413, 413<SP>1</SP>, 415 and 415<SP>1</SP>, bi-stable circuits 414 and 414<SP>1</SP> and monostable circuits 416- 418 are controlled by a clock pulse generator 400 and the difference signal when present, to step a counter 43 forward or backward in dependence on the difference being above or below the thresholds set by circuit 412. The count in unit 43 is converted in digital-analogue converter 45 to provide the L.O. correction signal. In the event that the incoming signal drops below a set value a threshold circuit 7 releases a relay 47 which opens the circuit to the counter 43. The count is stored and provides the correction signal until the incoming signal again exceeds the threshold value.

Title: Cigarette making machine for mouthpiece cigarettes
IPC: B22D18/06
Filed: 1959-07-13
Abstract: 930,803. Making mouthpiece cigarettes. AMERICAN MACHINE & FOUNDRY CO. July 13, 1959 [July 14, 1958], No. 23993/59. Class 130. [Also in Groups XVI and XXIV] When a respective one of triple photo-electric cells 28, Fig. 1, detects a deficiency in the feed of double-length filter plugs or flanking cigarettes on a mouthpiece machine assembly belt 27 formed as described in Specification 920,409, the feed of cork uniting band material 24 is interrupted. The cells 28 operate via an electrical circuit 30 described in detail (Fig. 9, not shown) and are effectively in series with (a) a centrifugal switch 31 which interrupts the material feed below a given machine speed and (b) a manual switch 32 depression of which interrupts the material feed. Feed interruption is effected by de-energization of a solenoid 33 which, as shown in broken lines in Fig. 8, normally causes rollers 35, 35A to hold the material 24 in contact with drive and gluing rolls 34, 34A, respectively, the material being released and brought into contact with a braking anvil 36 as the solenoid cuts out. Deficiency in the feed of cigarettes from a cigarette-making machine is detected by a further photo-electric cell 2, Fig. 1, which operates via electrical circuits 6, 10 described in detail (Fig. 5, not shown) to disconnect via a solenoid 3, and for the period of deficiency only, a plug feed dog clutch 7 (see Group XXIV) which on plug feed jamming also overrides and is then held disconnected by its actuation of a detector switch 5 which operates the solenoid 3. Actuation of a manual switch 11 de-energizes the solenoid 3 and re-connects the clutch 7 whether disconnection has been due to jamming or cigarette deficiency. To operate the mouthpiece machine without feeding plugs a manual switch 12 is provided which when operated disconnects the clutch 7 and prevents its reconnection even if the switch 11 is actuated. The switches 12, 32 are mechanically linked for simultaneous actuation. The material 24 is fed to a vacuum drum 15 electrically heated as in Specification 919,847 and which, to prevent scorching of cigarettemouthpiece assemblies, is lifted from and returned to the belt 27 on machine stoppage and starting respectively. To effect this, a main clutch lever 13, which controls the cigarettemaking machine as well as the mouthpiece machine and which is movable from a slowrunning through a neutral to a fast-running position, operates a micro-switch 14 which in combination with upper and lower limit switches 20, 21 actuates the control circuit 17 (Fig. 7, not shown) of a reversible motor 16 moving the drum 15 vertically through a link 18. A twosecond delay circuit 23 is incorporated to allow the lever 13 to be passed rapidly through neutral without initiating raising of the drum 15. The motor 16 has electrical braking means 22.

Title: Emergency or safety device for escalators, inclined conveyors and the like
IPC: B66B29/00
Filed: 1922-09-06
Abstract: 204,197. Waygood-Otis, Ltd., (Otis Elevator Co.). Sept. 6, 1922. Moving stairways.-Moving stairways of the kind having two chains driven by an electric motor are provided with a safety device which cuts off the current when the chains travel at different rates or when the stairway moves backwards. The chains 2 drive two sprockets 9, one of which is fast on the shaft 24 and the other of which is attached to a curved arm 11 free on the shaft. When the chains are driven at the same speed, a roller 12 on the arm 11 engages a recess in a member 14 which turns with the shaft, but on a difference of speed occurring, the roller leaves the recess and forces the member 14 to the left, Fig. 2. The movement of the membr 14 trips the trigger 19 of a switch 18 and cuts off the current. Springs 21 surround the bolts which connect the member 14 to a V-grooved drum 23 fast on the shaft 24. A pair of arms 40 are maintained in engagement with the drum 23 by rods 41 and are prevented from turning by the engagement of a projection 48 with a fixed part of the stairway. A finger 44 on one arm holds up the trigger 45 of a switch 46. When the stairway reverses, the arms will turn with the drum, the trigger will lose its support, and falling will cut off the current. In a modification, one sprocket is attached to a hub 30 loose on the shaft and formed with slots 31. Fingers 34 on the member 32 controlling the switch normally engage the full part of the hub, but when relative movement occurs the fingers pass into the slots and the consequent movement of the member 32 cuts off the current.
