Title: Apparatus for separating nested containers
IPC: B65G59/10
Filed: 1972-03-17
Abstract: 1391721 Discharging containers; feeding containers on to endless conveyers G R BOWD 14 March 1973 [17 March 1972] 12641/72 Headings B8S and B8A A stack 1 of containers is fed by means of a feed magazine 2 to a de-nesting station at which the leading container in the stack is de-nested and passes to a conveyer 15, the arrangement being such that a buffer plate 3, which is movable by virtue of being mounted on a wheeled trolley 4 which is operable by means of a crank mechanism 6, cam 13 and electric motor 5, is moved towards the stack and a jet of air from a nozzle 11 impinges on and spreads over the surface of the approaching buffer plate 3 thus creating a low pressure region across the face of the leading container which causes the leading container to be sucked towards and then into engagement with the buffer plate 3 and on movement of the buffer plate 3 away from the stack 1 the de-nested container moves down on to the conveyer 15. Latch members 9 mounted on the frame of the magazine 2 are biased into their operative condition in which they engage with the leading container in the stack 1, said latches 9 being moved to their inoperative condition by means of ramps 10 mounted on the buffer plate 3, so that when the leading container in the stack 1 has been fully denested on withdrawal of the buffer plate 3, the latches 9 hold the remainder of the stack pending the arrival of the buffer plate 3 prior to the de-nesting of the next leading container in the stack 4. The position of the air nozzle 11 is adjustable within the limits 11a, and the supply of air to the nozzle 11 is synchronized with the movement of the buffer plate 3 so that air is passed through the nozzle 11 only when the buffer plate 3 is in the region of the position for de-nesting a container.

Title: Microwave filters
IPC: H01P1/205
Filed: 1971-06-15
Abstract: 1358980 Microwave filters FERRANTI Ltd 15 June 1971 [17 March 1970] 12681/70 Heading H1W A narrow-band microwave filter comprises a number of electrically non-commensurate resonators separated by coupling sections of lengths not necessarily equal to an odd number of quarter wavelengths, the element values of the filter being in accordance with formulae comprising realizations of either inverse Chebychev or Elliptic junction approximations. Such filters may be of odd or even order and may provide symmetrical or asymmetrical characterestics. An outline of the theory of such filters is given in the Specification and the method of determining the dimensions of the resonators and coupling sections of the described embodiments is explained. In the fifth-order digital line filter shown in Fig. 4(a), the bar resonators 7-11 approximate to a half-wavelength and are short-circuited at either end. They may have different lengths and/or different cross-sections and/or different dielectric properties. The broken lines indicate the positions of tuning screws for the resonators and coupling sections. In a filter using resonators approximating to a quarter wave, the bars are open-circuited at one end. The even degree (fourth degree) waveguide filter of Fig. 7(a), comprises four stubs of different cross-sections arranged symmetrically about an impedance discontinuity 37 and coupled to the broad side of a rectangular waveguide 32. The positions of tuning screws are indicated by broken lines. An odd-numbered degree waveguide filter would have two impedance discontinuities.

Title: A method of, and apparatus for, driving a step-by-step conveyor hearth
IPC: F27B9/20
Filed: 1962-04-03
Abstract: 942,633. Drive for step-by-step conveyer. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 3, 1962 [April 5, 1961], No. 12737/62. Heading B8A. [Also in Division F4] The motion imparted to the moving supports of a step-by-step conveyer in a kiln for firing, e.g. ceramic ware, is such that all points on the supports move with circular motion but with non-uniform velocity such that at the instant of lifting and depositing the ware from and on to the fixed supports the moving supports are at a velocity minimum. By this means damage to the materials being conveyed through the kiln is avoided. Each mobile support is arranged longitudinally in the kiln between fixed supports and is supported by at least two eccentrics 9 carried on transverse shafts 10 which are driven through worm gearing 13, 14 by a longitudinal shaft 15. The latter is driven through multiplying gearing 16<SP>1</SP>, 16 from a Geneva cross mechanism 17, 18. The four stud wheel 18 rotating at constant angular velocity imparts to the Geneva cross 17 a rotary movement with four velocity minima per revolu tion. Gearing 16<SP>1</SP>, 16 and 13, 14 converts this movement to a rotation of shafts 10 having two velocity minima per revolution which can be arranged to coincide with the instants of lifting and depositing the materials from and on to the fixed supports.

Title: Improvements in or relating to ejection seats for aircraft
IPC: B64D25/10
Filed: 1950-05-22
Abstract: 679,063. Ejectable seats for aircraft. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO., Ltd. May 16, 1951 [May 22, 1950], No. 12820/50. Class 4. An ejection seat for aircraft is provided with thigh guards which remain in a retracted position during normal flight and on ejection of the seat are automatically or manually caused to take up an extended position. The seat 1 includes a seat pan 2 to the forward corners of which are pivoted port and starboard swinging arms 3 each carrying a curved strip or quadrant 4 having at its lower end a projection 5. The arms 3 are mounted on short spindles 6 the ends of which engage in torsion springs within a tubular casing, the inner ends of the springs being fixed to the seat pan 2. Each arm carries a pivoted catch 8 which is urged into engagement with a pin 10 on the seat structure by means of a spring loaded rod 12. The lower end of the rod 12 is spaced from one arm of a bell-crank 14 held in the position shown against the action of a spring 17 by means of a pivoted lever 19 which may be actuated by the occupant of the seat to release the bell-crank 14 and the catch 8 so that the members 3 and 4 may be urged into their operative positions by the torsion springs. The shock of release is absorbed by the projection 5 engaging a spring 9. The member 14 is connected to a rod 16 and a lever 28 which may be coupled to a mechanism actuated by the hood jettison control or other operative part of the seat ejection apparatus in order that the members 3 and 4 may be extended automatically when the seat is ejected. In a further embodiment, Figs. 5 and 6 (not shown), the member 3 may consist of a forwardly and upwardly inclined spring-loaded telescopic tubular member connected to a further tubular telescopic member which is substantially horizontal when the first mentioned telescopic member is extended. A manually or automatically controlled release mechanism is described for this latter embodiment.

Title: Contactor mechanism controlled by an electric meter
IPC: G01R11/60
Filed: 1947-05-12
Abstract: 627,445. Momentary-contact switches; actuation of switches. LANDIS & GYR SOC. ANON. May 12, 1947, No. 12826. Convention date, May 20, 1946..[class 38(v)] A contactor mechanism controlled by an electric meter comprises a feeler actuated by the meter 1 through reduction gearing 2, a momentary contactor 22 dependent on an auxiliary force, e.g. a motor 6, independent of the meter, and a step-by-step mechanism 11, 12, arranged between the contactor 22 and the motor 6 and operated by the motor 6, coacting with the feeler to control the contactor 22. The feeler comprises a disc 3 having peripheral recesses 4 and impact edges 5. The motor 6 drives a shaft 7 to which is secured a plate 8 carrying a relatively rotatable shaft 10 which carries a cam 13, two two-armed levers 11, 12 forming the step-by-step mechanism, and a fourarmed resetting member 14. The arms of the levers 11, 12 are offset by 90 degrees relatively to each other, and the arms of the member 14 are displaced by 45 degrees relatively to the levers 11, 12. The plate 8 also carries a spring-urged, bell-crank lever 16 co-operating with the cam 13 and having an arm co-operating with a spring 18 se- 'cured to a rotatable tilting plate 9, which is rotatable on shaft 7 and carries a cam 21, controlling the contactor 22. In the position shown, on clockwise rotation of shaft 7, the arm of lever 11 which is nearest to the disc 3 passes through a recess 4 and the contactor is undisturbed since the lever 16 moves on path 23 and does not engage the spring 18. Eventually, after continued rotation of the disc 3, an edge 5 thereon lies in the path of lever 11 which thereby rotates the shaft 10 through 45 degrees counter-clockwise. This causes the end of lever 16 to move into a recess in the cain 13, so that on continued rotation of shaft 7, the spring 18 is engaged by lever 16 to rotate the member 9 and actuate the contactor 22. The rotation of shaft 10 also causes the member 14 to move into the dotted position so that one arm thereof engages a fixed guide 15 which rotates the shaft 10 through a further 45 degrees, thereby putting an arm of the lever 12 in the path of the disc 3, and moving the lever 16 so that on rotation it does not engage the, spring 18. When the said edge 5 lies in the path of the lever 12, the contactor is actuated again, the cycle of operations being repeated. Since each edge 5 of the feeler operates the contactor twice twelve operations per revolution are obtained, but, by changing the gearing, up to about 120 operations per minute may be obtained.

Abstract: 1,062,692. Self-processing cameras. INTERNATIONAL POLAROID CORPORATION. March 26, 1964 [March 29, 1963], No.12872/64. Heading G2A. In self-processing cameras of the type illustrated by Figs. (not shown) 1 and 2, the image transfer process is effected by drawing the two sheets between pressure rollers (6) and (7), which rupture a capsule of processing liquid mounted between them, and thence out of the camera. The present invention is directed towards the mounting and arrangement of the said rollers, one of these being so mounted that it is biased towards the other, and is carried at its extremities by a pair of arms pivoted on a supporting surface, and which are long enough for the relative movement of the rollers to be substantially normal to the path of the sheet movement between them. Preferably, both rollers are so mounted. The rollers are assembled on a supporting frame 62 (see Figs. 3 and 4 not shown), the latter being an exploded view showing all the parts in detail. This comprises a transverse plate-like member (64) having side flanges 66, and is hinged at (68) by pivots 72 to the flanged sides 70 of a mounting plate 30. The front roller 6 is carried by a pair of side arms 84, which are hinged at (86) to the same pivots 72. The rear roller 7 is mounted between lugs (80) at the ends of the flanges 66 of member (64). Roller 6 has a flange 6a at each end, which bears against roller 7 to form a guide slot between them. Each side arm 84 is cranked inwards for most of its length, so that there is a long narrow space (87) Fig. 4 (not shown) between this cranked part and the flanges 66. In each of these spaces is located a U-shaped spring 96, its closed end (96a) adjacent the pivot 72. The open ends (96b, 96c) of each spring bear against lugs 90 and (92) on flanges 66 and side arms 84 respectively, so that the effect is to bias the rollers towards each other.

Abstract: 500,944. Automatic control systems ; driving-arrangements for ships. WOODWARD GOVERNOR CO. May 10, 1937, No. 13290. Convention date, May 9, 1936. [Class 38 (iv)] [Also in Group XXXIII] Relative speed synchronism of mechanical elements.-In a system for controlling the synchronism and phase relationship of rotary prime movers 6, 7, speed control of the prime movers is effected by control of the governors 8 by motors 6b, 7b, generators 6d, 7d driven by the prime movers being connected respectively to the stator and rotor of a motor 31 driving a pointer 35 over a scale to indicate the speed and phase relationship of the prime movers. The motors 6b, 7b have their rotors supplied from the respective generators 6d, 7d, and are controlled by " selsyn " motors 6c, 7c so arranged that when relay 50 is energized and switch 51 is in the right-hand position the motors 6b, 7b have their stators energized from the respective generators 7d, 6d through the " selsyh " motors 6c, 7c. The motors 66, 7b then operate to bring the prime movers 6, 7 into synchronism. The prime mover speeds may be regulated simultaneously by turning the member 21 manually to adjust the rotors of 6c and 7c together. The prime mover speeds may be adjusted independently when relay 50 is de-energized as when the governors are under manual control and contacts 6e, 7e are open. When manual control is removed and lamp 48<1> is energized the speed of either engine may be adjusted by turning knob 14 of motor 6c or 7c in series with its governor motor. The speeds may thus be adjusted until stoppage of the pointer 35 indicates that the prime movers 6, 7 are in synchronism the position of the pointer 35 indicating the phase relationship between them. Switch 49 may then be closed to energize relay 50 and lamp 49<1> so that the switch 51 is thrown over to cross connect the governor motors with the generators whereby the synchronization and phase relationship of the prime movers can be maintained. The system may be applied to the prime movers driving ships, aeroplanes, pumps or the parts of a paper making machine.
