Filed: 1961-12-22
Abstract: 955,624. Wrapping-machines; endless conveyers. CONTAINER CORPORATION OF AMERICA. Dec. 22, 1961, No. 46023/61. Headings B8A and B8C. In a machine for packaging groups of articles in an open-ended wrapper, wrapper blanks are carried on a chain conveyer 36 over rollers which supply adhesive and non-slip material to the inside of the blank from baths generally indicated at 50, the flat blank then being deposited on support elements 70. The articles are supplied by three parallel conveyers generally indicated at 92 in two adjacent rows, they are then stopped by rollers 112 and lifted by an upending mechanism 115 which moves in a vertical line. The arrangement is such that when the articles are lifted they can pass beyond the roller 112 and are carried by the central conveyer 90 to stop 150 where they are positioned directly below the wrapper blank which is supported on elements 70. A detector arm 147 is supplied to work in comjunction with a hook 144 to arrest the flow of articles in the event of there being any irregularities in the supply. A first folding member 164 in the shape of a rectangular box folds down two sides of the wrapper and carries the articles in the wrapper to a position where they are picked up by the next forming member 165 when a transversely moving flap-folding member 229 folds in a short bottom flap of the wrapper in such a way that support plate 163 is between the bent-over flap and the bottom of the article group. As the partially wrapped articles are carried on by forming member 165 a plow 252 folds up the short flap into contact with the article group. The same process is carried out by forming member 166, flap-folding element 259 and plow 264 to bend over a long bottom flap which overlaps said short flap. The forming boxes are carried by a beam 167 which is counterbalanced by coil spring 214 and guided by the location of a pin in a channel 175 between two parallel rails. The wrapped articles are then deposited on to a conveyer (not shown) which extends perpendicular to the direction of travel of the forming sections. Upright members on the conveyer attached to adjacent links hold the package in a closed position until the adhesive dries. Articles are placed on an endless conveyer 22 at a point above sprocket 271 between members 268, 269; as the conveyer moves, members 268, 269 grip the package and hold it in position while the adhesive, applied by the machine, sets. The conveyer is driven intermittently in one direction by the action of a reciprocal rack 280 on a rotor 284 and the action of a spring-loaded detent 285 in slots 286. The detent grips the face 288a of a slot 286 when driving the conveyer and rides up a sloping face 288b of slot 286 during the return movement of the rack to cause a dwell in the conveyer movement. The final drive is provided from a sprocket on shaft 278 which drives a sprocket 276 on the conveyer by means of a chain 275.

Title: Device for controlling the bleed of air from a gas turbine engine compressor
Inventor: HERBSTRITT KARL
IPC: F04D27/02
Filed: 1966-10-17
Abstract: 1,115,968. Valves. ROLLS-ROYCE Ltd. 17 Oct., 1966, No. 46378/66. Heading F2V. [Also in Division G3] A bleed valve for controlling the bleed of air from a gas turbine compressor comprises a valve closure 33 controlling bleed ports 32, the valve being connected to a piston 28 which is actuated by a pure fluid switch. The pure fluid switch comprises a main jet 20 fed from a second stage compressor 13 and control jets 62, 65 fed from a first stage compressor 12. The jet 62 is fed from a chamber 63 supplied through a restrictor 64 and the pressure at 65 is normally below the pressure at 62 so that the main jet flows through duct 22 and acts in a chamber 24 on piston 28 to close the bleed valve. In the event of surge, the pressure P 2  supplied to the control jets drops suddenly causing a rapid drop at jet 62 and the higher pressure at 65, due to the chamber 63, switches the main jet to duct 23. The main jet then flows past non-return valve 57 to chamber 25, thus opening the bleed valve, while part of the flow in duct 23 flows through passage 66 to provide a further or holding switching action on the main jet. The valve acts as a quick opening, slow closing valve. When the valve opens, the fluid in chamber 24 is exhausted first through a duct 55 and then through non- return valve 41, after the port 55 has been closed by the piston 53. When the valve closes, the fluid in chamber 25 can only exhaust through an adjustable bleed 45. The bleed valve may be actuated for a normal control function instead of as a surge control by the control jets being connected to certain pressure sources such as compressor pressure, down stream pressure or ram pressure. In a modification, the movement of the bleed valve varies a restriction in one of the control jet supplies to oppose closing movement of the bleed valve.

Abstract: 1,220,637. Differential amplifier and pulse detector. INTERNATIONAL BUSINESS MACHINES CORP. 1 Oct., 1968 [11 Oct., 1967], No. 46421/68. Heading H3T. Two transistors 21, 23 of a differential amplifier receive differential signals at 17, 19 and each has a resistance divider 45, 47 and 49, 51 connected to its collector; and a difference detector 15 has its two inputs connected to different points 53, 59 in the respective dividers. A pulse (A, Fig. 2, not shown) from a core store is applied to input terminal 19 and an equal and opposite pulse to terminal 17, so that the normally balanced conduction in transistors 21, 23 is decreased and increased respectively. Consequently the collector potentials, which were equal, move oppositely, and at a stage where the collector 53 potential (c) becomes positive with respect to the intermediate point 59 potential (B), a normally conducting transistor 69 and a normally non-conducting transistor 71 in the detector 15 change states to give an output current at 75. The threshold before this output current appears in response to an input pulse at 17, 19 is adjusted by varying the potential divider ratio. A second identical detector 13 has its two inputs oppositely connected to corresponding points 55, 57 in the dividers, and responds to an input signal at 17, 19 of opposite polarity.

Filed: 1973-10-05
Abstract: 1450923 Adaptive equalisers PLESSEY CO Ltd 23 Sept 1974 [5 Oct 1973] 46733/73 Heading H4R In a data transmission system in which a receiver 3 includes an adaptive equaliser 5 which is selectively adjusted and has its output sampled for distortion equalisation, the sampling time of the equaliser output is varied in accordance with the error rate of the equaliser output in order to provide improved distortion equalisation. As described the equaliser output comprises a multi level analogue signal which is quantised and converted to 5 digit form, the first three digits representing the data information, the fourth digit providing an error signal Ve giving an error direction signal used to adaptively adjust the equaliser 5, while the fifth digit provides a further error signal which indicates whether the received level is nearer the mean value of the particular level or is nearer to the upper or lower limit of that particular level, and which is used to control the adaptive timing of the equaliser output-sampling. The sampling signal is derived from a pilot frequency fp received with the data signal and which is extracted by filter 11, Fig. 2, squared at 12, and used to control a phase locked oscillator 13. The phase of the sampling signal Pt relative the received pilot frequency is controlled by the output of d to a converter 17 connected to counter 16. The counter 16 is stepped each time an output is produced by the fifth bit counter 14, i.e. whenever a predetermined number of "fifth bits" of the quantised received signal have been determined as one, while the stepping direction of counter 16 is controlled to change each time the period between the outputs from the fifth bit counter reduces, indicating an increase in error, and is maintained to count in the same direction, either up or down, when the period between outputs from the fifth bit counter 14 increases, indicating a decrease in error. In order to provide a uniform rate output irrespective of the phase of sampling the sampled signals from the equaliser output are fed into an elastic store 7 and clocked out therefrom by the input Pc to the phase locked oscillator. During periods of gross errors, such as immediately after start-up the normal adaptive variation of timing is interrupted and the timing adjust counter is just scanned successively up and down until the error rate falls to a predetermined level.

Abstract: 1,165,961. Centrifugal and axial-flow pump and compressors; turbines. GARRETT CORP. Oct. 19, 1966 [April 4, 1966], No.46787/66. Headings F1C and F1T. In a machine for transferring energy, a fluid is caused to flow at least twice through a series of blades 16 on a belt 17, to supply energy to or draw energy from at least one of the shafts 10. In the embodiment shown, the machine is a pump having a casing 15, an inlet passage 13 and an outlet passage 14. The inlet and outlet passages and associated casing portions cause the fluid to have uniform energy distribution before its first pass and after its final pass through the blades, and a non-uniform energy distribution between the passes. In Figs. 3a, 3b (not shown), the blade belt is in the form of a ring and mounted on either the periphery of a disc or the ends of an arm to form a rotor, and a substantially toroidal casing surrounds the rotor and internally receives the blades thereof. During operation, the fluid circulates around the interior of the toroidal casing substantially transversely to the direction of rotor rotation and thereby makes several passes through the blades. A toroidal shroud within the toroidal casing is either secured to the tips of the rotor blades or is stationary and closely spaced from the free ends. With compressible fluids, the flow passage area of the casing may decrease in the direction of increased fluid density, but not to a value at which the projected area of the blades in a plane perpendicular to the direction of rotor rotation is less than the projected area of the surrounding portion of the flow passage.
