Title: Packaging Machine and Method.
IPC: B65B31/02
Filed: 1968-03-18
Abstract: 1,178,353. Packaging-machines. INTERNATIONAL MACHINERY CORP. S.A. 18 March, 1968 [14 April, 1967], No. 12955/68. Heading B8C. Apparatus for filling the headspace of filled containers with an inert non-condensible gas and sealing on lids comprises means to withdraw air from the containers and replace it by gas while the lids are clinched in position and means to heat the gas within the containers to prevent ingress of air before final sealing. In one embodiment which is an adaptation of the vacuumizing and gassing apparatus described in Specification 1,034,915, vacuum chambers 14 are carried on a rotary head 11, the filled containers C with lids attached being fed on to lower chamber closure members 13 by a star-wheel 21. The members 13 rise to feed the containers into the chambers and seal the base of the latter. Chamber top closures 16 are carried by a chain 17 and seal the chambers during intermittent clockwise rotation of the head (Fig. 2) from adjacent the star wheel 21 to the vicinity of a heating plate 8. During this period, low and then high vacuum are applied followed by infeed of the gas. When the plate 8 is reached, the closures 16 slide off the chambers which are progressively closed by the plate. This heats the gas to about 5‹ F. above ambient temperature and this is sufficient to prevent inflow of air. The containers are then aligned beneath a rotary sealing head 19 which may also be heated for the same purpose and are finally ejected by a star wheel 22. In another continuously-operating embodiment, Figs. 4, 5 (not shown), the filled containers are passed by a star wheel and then an endless conveyer, through a heated tunnel from which they emerge into a rotating lid sealing turret. Reference has been directed by the Comptroller to Specification 1,034,915.

Abstract: 1,195,187. Photo-electric interferometers. HEWLETT-PACKARD CO. March 12, 1969, No. 13092/69. Heading G1A. In an interferometer, the beat frequency of two laser beams of different frequency directed along the interferometer paths is compared with the beat frequency of the two beams directed along relatively fixed paths. Beams at frequencies f 1  and f 2  from lasers 10, 14, Fig. 1, are reflected by the semitransparent mirror 18 to a square law detector to produce a reference frequency # R  = # 1  f 2  and transmitted along the interferometer paths 12b, 16b. The transmitted beams are reflected back to the mirror 18 by a mirror 30 and detected by another square law detector 42 to give a frequency f c  =f 1  - f 2  Œ#f where #f depends upon the speed of movement of the prismatic corner cube reflector 34. The frequencies f R  and f 0  are applied to the up and down inputs of a reversible counter 44 so that the count indicates the position of the corner cube 34. Frequency synthesizers may be provided between the detectors and the counter to increase f c  and f R  to such an extent that the counter reading indicates the position of the reflector 40 directly in well known units. The lasers may be replaced by a single laser Fig. 2 (not shown) producing overlapping beams of orthogonal circular polarization by Zeeman splitting. A quarter wave plate converts the beams to orthogonal plane polarization for splitting by a semi-transparent mirror and crossed polarizers. The reference beams are taken from the opposite end of the laser.

Title: Improvements in or relating to reversing gear mechanisms
IPC: B63H25/20
Filed: 1936-05-08
Abstract: 474,790. Hydro-mechanical forward and reverse driving-gearing. SINCLAIR, H. May 8, 1936, No. 13116. [Class 80 (ii)] [Also in Group XXXIII] Forward and reverse torques in a driven member are generated at will by means of the hydraulic drag in an hydraulic coupling acting through two friction clutches to produce the two opposing torques simultaneously, one of the torques being annulled by opening its clutch so as to leave the other torque effective. Thus, a worm shaft 16 is driven in either direction at will to operate a ship's rudder post 21 by opening a clutch 12 or a clutch 12<1> of one or other of two trains which is to be rendered ineffective. A shunt-controlled motor 1, which runs slowly when its control arm 43 is in the mid-position shown, drives the impeller 2 of an hydraulic coupling of the kind having a reservoir 5 between the back of the runner 3 and a dished casing 6 fixed thereto, as described in Specification 385,086, [Group XXIX], the working liquid being in part transferred to this reservoir when the rotor 3 is stalled. A torque is thus constantly transmitted through the runner shaft 4 to a bevel gear 9 which applies torque to two bevel gears 10, 10<1> to rotate them in opposite directions. Thus opposite torques are imparted simultaneously to two shafts 11, 11<1> which are normally connected through the two friction clutches 12, 12<1> to two pinions 14, 14<1> in mesh with wheels 15, 15<1> on the worm shaft 16 which is constantly geared to a quadrant 20 on the rudder post 21. Since the pinions 14, 14<1> tend to turn oppositely, both are held fast while slip goes on in the hydraulic clutch. When the ship's wheel 27 is turned to pull a screwed rod 29, a floating lever 31 pivots downwards about a pivot 37, thrusting downwards a rod 33 with a cam plate 34. This pulls right a clutch rod 24 with a stop 25 which opens the clutch 12 against its spring 23. As the rod 33 is displaced it turns the lever 43 which accelerates the motor 1 and the hydraulic coupling now responds to a magnified torque which is transmitted through the other clutch 121 and the pair 14<1>, 151 and on to the rudder quadrant moving it clockwise so that the right end pivot 37 of the lever 31 is depressed through a linkage 40, 39, 38 so as to raise the rod 33 and so return the hydraulic coupling and the motor to stalled position with the rudder locked. Arrangements are described each with a separate hydraulic coupling in series with each friction clutch. Instead of friction clutches, equivalent epicyclic trains, each with its controllable brake, may be used.

Abstract: 758,872. Prestressed reinforced concrete. STANTON IRONWORKS CO., Ltd. May 5, 1955 [May 4, 1954], No. 13136/54. Class 20(4). [Also in Group XXVIII] A method of making concrete pipes reinforced by a pre-stressed wire helix embedded therein comprises winding the wire 2 with a tensile stress onto a cast core 4, heating the wire or the wire and the core, such as by a low voltage electric current, torelieve the tensile stress, inserting a mandrel into the core to resist contraction of the latter, disconnecting the heating, applying a coating of concrete over the winding and curing it and then withdrawing the mandrel either by collapsing the mandrel or by re-heating the wire or the complete pipe. As shown the mandrel consists of a tube 12 with a flexible jacket 14, one end 16 of the mandrel being removable. The jacket may be in two layers or a single layer clamped at each end to the mandrel. The annular space 18 is filled with water and when the coating has been applied the water is emptied to enable the mandrel to be withdrawn. In a modification the coating of concrete is applied over the winding whilst the latter is heated, the heating continuing during the application and curing of the coating so that a mandrel is not required.

Abstract: 1,179,625. Lasers. UNION CARBIDE CORP. 21 March, 1967 [5 July, 1966], No. 13234/67. Heading H1C. The output from one laser is used to trigger Q spoiling means in the optical cavity of a second laser to thereby trigger the operation of the second laser. Light 15 from a ruby laser 10 is passed through bleachable dye cell 21 in the optical cavity 19, 20 of a second ruby laser 16, Fig. 1. The bleachable dye cell is bleached by light 15 and thus Q-switches the second ruby laser 16 to cause a light beam 22 at the same frequency as that from laser 10 to be emitted through partially reflecting mirror 20, the two output beams being locked in frequency by the bleachable dye solution. Output beam 15 is delayed by the optical delay 24 to account for the bleaching time of the cell before the two beams 15, 20 are combined in beam splitter 26, operating in a reverse manner, to produce output 27, the beam splitter including a semi-transparent mirror. The laser 10 may be Q-switched by means of a bleachable dye cell in its optical cavity to produce a giant triggering pulse, Fig. 2 (not shown). The two lasers may have a common dye cell in both cavities. Fig. 3 (not shown), in which case one of the lasers is pumped to a level to fire first thereby causing the second laser to fire. Instead of varying the pumping intensities to cause one laser to lase before the other, the dye cell may be rectangular so that it will be bleached by laser radiation passing through the short dimension before radiation passing through the long dimension. In the arrangement of Fig. 4, radiation 50 from laser 49, when triggered, passes in succession through dye cells 51, 52, 53. The output beams 57, 62, 66 are combined as shown by means of reversed beam splitters 61, 65 to produce a large output 67. The optical delays may be omitted.

Abstract: 218,441. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. May 17, 1923. Electromagnetic switches; quick-action.- Successive energizations of the operating solenoid raise a core which acts through a forked lever in a disc carrying two eccentric pins whereby the disc is rotated in opposite directions and, through toggle mechanism, moves a switch member over into opposite extreme positions where it is retained by a spring. As shown, the movable plunger 26 serves to raise a flanged sleeve and thereby raise a double-armed lever 44 pivoted at 23 and carrying at its free end a pivoted forked arm 45 maintained in the position shown by a control spring 48. The switch is shown in one of its extreme positions, and, in rising, the arm 45 engages the eccentric pin 42 on the disc 33 and drives the disc in the clockwise direction, thereby raising the link 35 which is pivoted eccentrically on the disc at 34 and to the movable contact-member 22 at 36. The upward movement of the link 35, which with the disc constitutes a toggle operating-mechanism for the contact-member is continued, against the action of the spring 38, until the vertical dead-centre position of the eccentric pin 34 is passed when the spring forces the toggle and with it the contact-member into the other extreme position. With the second energization of the solenoid, the forked arm engages the second pin 43, which has assumed the lower position, and drives the disc in the anticlockwise direction thereby restoring the switch to the original position.

In an automatic volume control system the variation of collector resistance with base current of a transistor operating below the knee of the collector current-collector voltage characteristic is used to control either the signal level fed to an amplifier or the amplifier gain. Fig. 2 shows the audio stages T1 and T2 of a transistor car radio, negative feedback being applied from the secondary of the output transformer OT to the emitter circuit of transistor T1 via a control circuit incorporating transistor T3. The collector impedance of T3, which forms with resistor R6 a potentiometer across the audio output, is controlled by a potential applied to the base via the terminal B, the potential being derived from a source dependent on the speed of the engine, so that as the engine speed increases the collector resistance of T3 decreases, reducing the feedback voltage and increasing the gain of the amplifier. The D.C. potential for transistor T3 is obtained by rectifying the audio output of the amplifier with diode D.
