Title: A transmitter of the force balance type having means for zero adjustment
IPC: G01F1/38
Filed: 1966-02-15
Abstract: 1,142,522. Transducers. LEEDS & NORTHRUP CO. Feb.15, 1966 [Feb.23, 1965], No.6646/66. Heading G1N. In a transducer of the force balance type for measuring e. g. the differential pressure across an orifice as a measure of fluid flow, and in which a square law response is required, means are provided to switch to a linear mode to facilitate zero setting. In normal operation, the pressure differences are applied on either side of a diaphragm 14 to cause movement of one plate 27 of a capacitor which is included in an undisclosed oscillator-amplifier circuit 10a, Fig. 3 the output of this circuit energizes a coil 30 moving in the field of an electromagnet 32 so as to pivot a beam 31 and, via a flexible link 42, restore the capacitor plate 27 to its original position. The current through coil 30 is indicated on a meter M. The range of the transducer is set by adjusting the air gap of the electromagnet. The square law response is achieved by connecting the coil 32f of the electromagnet in series with the moving coil 30. To set the zero position, the suitable S is changed over so that the magnet coil 32f is energized from a fixed voltage source and hence gives a linear response. In an alternative embodiment, Fig. 4 (not shown) the linear mode is achieved by short circuiting the moving coil 30 and transferring its signal current to a similar coil 33 which operates in the field of a permanent magnet. Normally the coil 33 is short circuited and provides damping.

Title: Improvements in cathode ray apparatus for portraying intelligence
IPC: H01J29/18
Filed: 1944-04-12
Abstract: 613,105. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 12, 1944, No. 6781. Convention date, Nov. 20, 1942. [Class 39 (i)] A cathode-ray tube for portraying information, such as radar traces, in the form of a dark trace on a luminous background, includes a luminescent material having the property that, at temperatures above the optimum for ultra-violet excitation, the curve connecting its efficiency under electronic bombardment with temperature (CR, Fig 2) lies above the corresponding curve connecting efficiency under ultra-violet irradiation with temperature (UV1, Fig. 2). The screen 4, Fig. 1, is scanned by the electron beam from gun 5 .... 8, is heated to an optimum working temperature by heater 13 or infra-red lamp 14, is uniformly irradiated with ultra-violet light from lamp 15 or 15a and is observed from front, 16a, or back, 16. In the absence of electronic excitation, the screen is at temperature Ta2, Fig. 2, and the light emission is represented in arbitrary units by ordinate Ta2-F. When a given area is first struck by the beam, its emission rises by summation of effects to Ta2-G, giving a bright flash. As the area heats up under electron bombardment, its temperature rises to Tb and its emission declines to Tb-H. Upon removal of electronic excitation the emission drops to Tb-P, giving a dark spot on the luminous background. As the area loses heat by radiation or conduction, its temperature falls to, say, TCR, and its emission increases; thus, the blackness of the dark spot falls off regularly with time, enabling old information to be distinguished from new. Upon again being struck by the beam, however, the intensity again rises to, say, TCR-M, so that an initial flash is superimposed on the old trace, followed by an intersification of the darkening to Tb-P as before. The screen temperature may vary between 50‹ and 400‹ C. and the beam voltage may be from 1000-60,000 volts; for the zinc cadmium-sulphate screen giving the curve UV1 (88 per cent zinc, 12 per cent cadmium, 0.008 per cent copper activator), the optimum values are 200-300‹ C. and 6000 volts. Such a beam at .30 microamps will darken the screen in less than one second when the ultra-violet excitation is mainly at 3650 A. Curves are also given for silver-activated zinc sulphide and manganese-activated zinc silicate. Other suitable materials are cadmium sulphide, zinc or cadmium sulpho-selenide, zinc beryllium silicate, the borates or aluminates of the Group II metals (preferably irradiated by 2537 A), or germanates (irradiated by either 2537 or 3650 A). The material may be on the inside of the envelope as shown, or on a mica sheet within the vacuum, or in air. In the latter case, it is preferably deposited on the outer surface of a Lenard window through which the electrons penetrate to excite the material; curve UV2, Fig. 2, shows, for the same material as curve UV1, how this arrangement modifies the efficiency-temperature curve while still remaining suitable for the invention.

Title: Improved drive mechanism for folding box machines of the plunger and die type
IPC: B31B50/46
Filed: 1963-02-21
Abstract: 955,132. Box making machines. ATLAS GENERAL INDUSTRIES Inc. Feb. 21, 1963 [March 13, 1962], No. 6967/63. Heading B5D. A die and plunger type box erecting machine comprises a reciprocating drive means for moving a plunger 12 into a blank folding die, a pneumatic piston 68 and cylinder 66 between the drive means and the plunger, and an hydraulic piston 85-86 and cylinder 67 containing an inner cylinder 77 arranged in parallel with the pneumatic cylinder. This arrangement obviates the necessity for adjusting the force and motion transmitting device when blanks of different size are erected. Details of the driving means are disclosed in Specification 901,591. The pneumatic cylinder, which is divided into two chambers by the plunger, has its upper chamber 71 vented to the atmosphere, and its lower chamber 72 sealed by a check valve sealing a passage 75 when sub-atmospheric pressure exists in the chamber 72 and open to vent when above-atmospheric pressure exists. During the work stroke atmospheric pressure acting on the top side of the piston 68 pushes the piston downward inside the cylinder 66, and this motion is unrestricted during the initial portion of the stroke and is restrained as soon as the rod piston 86 enters the inner cylinder 77 of the hydraulic unit. The cylinder 77 has means forming a restricted passage for discharging liquid at a controlled rate when the volume is being reduced and a valve means 79-80 provided for admitting liquid when the volume of the chamber is being enlarged. The box blank has its sides S folded against the plunger by folding elements 14 and 15, glue applied to flaps F by applicators 23 which also prefold the flaps at an angle to the side panels so that upon entry of the blank into the die, the flaps F overlie the end surfaces of the plunger, and end panels E lie thereover and become adhesively secured thereto. In a modification the cylinder and piston type may be of the rotary design in which a pivoted vane-piston divides a substantially sector shaped cylinder into the chambers.

Title: Apparatus for wrapping up quantities of small articles
IPC: B65B11/54
Filed: 1925-03-16
Abstract: 252,090. Beecham Estates & Pills, Ltd., and Sumner, W. March 16,1925. Packeting pills and small articles by wrapping- up.-An open-topped receptacle is formed by a hollow plunger which presses a wrapper through a hole in a fixed plate and a number of pills or other small articles are fed through the plunger into the receptacle; the mouth of the receptacle is then closed by two pairs of grippers, one of which holds the upper end of the receptacle stationarv while the other twists the neck of the receptacle. A wrapper thrown from the bottom of a receptacle 12, Fig. 1, is carried by a reciprocating arm 19 until it lies over an aperture 26 in a fixed plate 23, and a plunger 8 operated from a sliding carriage 2 by means of levers 44, 47 then descends and forces the wrapper through the aperture 26, thus forming an open-topped receptacle round the lower end of the plunger. The hollow plunger 8, which receives pills &c. from a hopper 62, is provided with a measuring-device comprising shutters 57, 58 connected to a lever 59 operated by fixed stops 61, 62, movement of the shutter 58 to the left allowing the desired quantity of pills to drop into the paper receptacle when the plunger 8 reaches the bottom of its stroke. When the carriage 2 returns to the left a pair of grippers carried by spring-pressed pivoted rods 29, Figs. 1 and 11. grip the mouth of the receptacle immediately below the aperture 26, and a second pair of grippers 10 carried by spring-pressed arms 35 mounted on a discharge tube grip the neck of the receptacle. As the carriage 2 completes its movement to the left, a rock 50 engaging a pinion 53 rotates the arms 35 and thus twists the neck of the receptacle, which falls down the discharge tube as soon as both pairs of grippers are opened during the subsequent advance of the carriage 2. A free-wheel clutch causes the grippers 10 to rotate in one direction only. Feeding wrappers. The wrappers are drawn from the base of a storage receptacle 12, Figs. 1 and 8, by rubber pads 20 on a resilient arm 19 pivoted to a block 17 mounted on the reciprocating carriage 2. As soon as the arm 19 commences to move away from the receptacle 12, a pawl 21 pivoted on the arm is turned by engagement with the fixed plate 23, thus raising the arm 19 slightly and causing the pads 20 to take the lowest wrapper and carry it forward beneath a resilient plate 24 extending from the receptacle 12. Directly the pads 20 leave the plate 24 the pawl 21 drops in a slot 25 in the plate 23, thus allowing the arm 19 to fall and to deposit the wrapper over the aperture 26.

Abstract: 525,983. Four-stroke engines ; valves. MAWEN MOTOR CORPORATION. March 4, 1939, No. 7169. Convention date, March 5, 1938. [Classes 7 (ii) and 7 (vi)] [Also in Group XXVI] In an engine in which radial or tangential cylinders have ported ends 46 fitted with packing-sleeves 50 bearing against a valve 22 surrounding all the cylinders and formed with inlet ports 40 and exhaust ports 42, relative rotary motion occurring between the cylinders and the valve, the packing-sleeves 50 are so constructed and arranged that they become slightly tilted in order to provide a wedgeshaped lubricant space between each packing- sleeve and the valve opening forwardly in the direction of relative movement of the packing- sleeves. In the engine shown, the valve is stationary, and the crank shaft and cylinders rotate in opposite directions ; but the valve may rotate. The effect desired is obtained by making the bores 98 of the packing-sleeves eccentric, so that the resultant of the cylinder pressures, and also the centrifugal force, acts to one side of the centre of gravity of the sleeves and causes the required tilting, 'the sleeves having slight play in the ports 46, which is taken up by packing-rings 66. Further packing- rings 64 are arranged between the flanged outer ends of the sleeves and holes 62 provided to receive these flanged ends in a circular shoe 58 surrounding all the cylinders. The valve 22 and the sleeves 50 and shoe 58 are spherically curved on their engaging faces. The shoe 58 is connected to one of the cylinders by an adjustable screw coupling 82. Springs 92 press the packing-sleeves outwards.
