Title: Improvements relating to Caps or Closures for Collapsible and other Tubes, Bottles, and the like.
Inventor: KNASTER IGNATIUS
IPC: B65D35/42
Filed: 1918-04-26
Abstract: 120,000. Knaster, I. April 26, 1918. Stoppers, connexions to prevent loss of; stoppers; spring.-Caps or other closures for collapsible or other tubes, bottles, sprinklers, or other receptacles are permanently secured to the tube &c. by a spring device made of spring wire with one arm attached to the vessel and projecting laterally away from the neck thereof and terminating in a spring coil c, the other end of the wire being attached to the cap, &c. The spring coil c is stressed so that it either tends to spring open with the cap when the latter is released, or tends to hold the cap pressed down on the orifice until it is lifted and turned aside, when the spring holds the cap down and out of the way of the orifice. As shown in Fig. 2, one end of the bent spring wire is fastened at d around the neck of the tube a, while the other end is looped at e around the central knob of the screw cap b. Fig. 3 shows the cap b locked in the closed position by an extension f of the wire beyond the loop e engaging a hook g formed by an extension of the wire beyond the. part d. Figs. 6 and 8 show the device applied to the screwed metal stopper b of a glass phial a, the stopper having a central hole through which the end of the spring wire is passed, as at h. The end of the wire inside the cap b is coiled or flattened, and a disk k of cork &c. is inserted in the cap. Fig. 10 shows the alternative form of the device wherein the spring c tends to hold the closure on the aperture of the vessel a. One end of the spring is looped around a stud l on the shoulder of the vessel, while its other end is soldered to the cap b. When the cap is lifted and turned aside, the spring c holds it against the shoulder of the vessel. Fig. 12 shows a vessel a closed by a diaphragm m which is pierced when the contents of the vessel are to be discharged. The cap h has a. central spike n, and contains a ring o of cork, rubber, &c. To prevent premature perforation of the diaphragm, a cardboard disk p is placed in the cap. For closing a vessel containing co-agulating adhesive, a pin or prong q, Fig. 14, is carried by the end of one arm of the coiled spring e, and a projecting finger-piece r is provided. The collapsible tubes &c. may be mounted on a card by inserting the spring loops c in slots in the card, and a rod may be passed through the loops of a row of springs to secure them to the card.

Title: Improvements in and relating to the tempering of glass
IPC: C03B27/052
Filed: 1936-03-10
Abstract: 471,813. Tempering glass. HERZOGENRATHER GLASWERKE BICHEROUX & CIE, GES. March 10, 1936, No. 7226. Convention date, March 13, 1935. [Class 56] Relates to the method of tempering a glass plate in which the cooling is effected by jets of cooling medium directed from nozzles against both surfaces of the plate. According to the present invention, the plate is introduced between the nozzles while they are separated by a distance greater than that which is suitable for effective cooling, and they are then moved towards the glass until their distance from it gives the rate of cooling necessary for effective tempering. The cooling device may consist of two frames supporting a number of parallel tubes 4 pierced with jet orifices and connected with headers having air supply pipes 3. The two frames are slidable to and from one another along rails 19, 20, and are moved by a crank disc 23 which is connected to the frames by links and is operated by a handle 24. In another construction, the frames are moved by means of screwed rods which are turned simultaneously by means of endless chains. In operation, the frames are separated and the hot glass plate 5 is introduced between them, the plate being suspended by tongs 6 in the usual way. The frames are then moved to bring the jet orifices to the best distance from the plate. The cooling medium may be air or steam, or air or steam holding in suspension water in a finely-divided condition. The frames are preferably oscillated or moved in closed paths in the usual way.

Title: Improvements in or relating to the purification of gases or gas mixtures
Inventor: WEBSTER THOMAS JOHN
IPC: C01B23/00
Filed: 1952-03-21
Abstract: <PICT:0730014/III/1> Oxygen or hydrogen is removed from an inert gas or gas mixture, e.g. nitrogen, argon, krypton, helium, neon, and xenon, by adding to the impure gas or gas mixture an amount of hydrogen or oxygen such that in the resulting gas mixture hydrogen and oxygen are present in approximately the stoichiometric proportions to form water and passing the mixture through a two stage purification system, the first stage being adapted to effect maximum possible conversion of the hydrogen and oxygen to water, and the second stage being adapted to perform the dual function of converting to water any residue of the oxygen-hydrogen mixture and of removing any oxygen or hydrogen in excess of stoichiometric proportions, the amount of hydrogen or oxygen added to the impure gas or gas mixture being automatically controlled in accordance with the content of hydrogen and oxygen in the gas leaving the first stage. Hydrogen or oxygen entering at 3 is mixed with the impure gas entering at 4 and the gas mixture passes to the first stage, where conversion to water takes place in a burner and/or in the presence of a catalyst, e.g. palladium deposited on platinum gauze.  The rate of addition of hydrogen or oxygen is controlled by valve 5 operated by controller 6 coupled to a differentially coupled oxygen-hydrogen analyzer 7 in the outlet 8 from the first stage. The gases then pass to second catalyst stage, e.g. the same catalyst as first stage, followed by an absorbent capable alternatively of oxidizing to water any excess hydrogen or of combining with any excess oxygen, e.g. a mixture of copper and copper oxide.  Alternatively, an absorbent capable of acting as a catalyst for the conversion may be used alone in the second stage, e.g. a mixture manganous and manganousmanganic oxides. The control may be set and re-set to give an excess of oxygen and hydrogen alternately in the gas passing to the absorbent so that the latter is automatically regenerated, and this setting of the control is conditioned by analysis at 10 of the gas passing from the second stage.

Title: Electron Beam Apparatus
Inventor: CAMPBELL ALISTAR JOHN
IPC: G01N23/203
Filed: 1967-02-16
Abstract: 1,195,271. Electron beam apparatus. CAMBRIDGE INSTRUMENT CO. Ltd. 13 Feb., 1968 [16 Feb., 1967], No. 7463/67. Heading H4F. [Also in Division H1] To analyse the surface of a specimen S, Fig. 1, and display the topographical features or the distribution of the various elements present (atomic number distributions), an electron beam B is caused to impinge on the surface of the specimen and the back-scattered electrons are detected by at least three electron dectors D 0 , D 1 , D 2  spaced around the path of the electron beam. The output signals of the detectors are either added to produce a signal dependent on the atomic number of that region of the surface of the specimen on which the beam impinges, or the output signals are mixed in such a way as to produce a signal that is independent of the atomic number but is dependent on the topography of that region of the surface on which the beam impinges. The latter signal may either be preferentially dependent on topographical features whose general direction runs substantially perpendicular to an arbitrary direction which may be controlled without moving either the specimen or the detectors, or is equally dependent on all topographical features whatever their direction. By scanning the electron beam over a small selected area of the specimen and synchronizing therewith a display on a cathode-ray tube screen or on a two-co-ordinate plotter a picture of the element or topographical features is produced. The topographical dependent signal D = d 0  cos # + d 1  cos (120 + #) + d 2  cos (240 + #), where d o , d 1  and d 2  are the outputs of three detectors symmetrically spaced around the path of the electron beam and # is the angle which the projection of the line to the detector D 0  makes on the surface of the specimen with an arbitrary line in the specimen surface which may be described as the direction of apparent illumination. For four symmetrically spaced detectors D = (d o  - d 2 ) cos # - (d 1  -- d 3 ) sin #. In addition to providing a selector switch for plain addition or the combination in accordance with the above equation of the signals, a knob may also be provided for varying the angle # so that irregularities in any selected direction may be examined. In alternative arrangements in which the detectors do not have to be symmetrically arranged, the topographical dependent signal displayed equals (d<SP>1</SP> - d 0 ) + (d<SP>1</SP> - d 1 ) + (d<SP>1</SP> - d 2 ) or (d<SP>1</SP> - d 0 )<SP>2</SP> + (d<SP>1</SP> - d 1 )<SP>2</SP> + (d<SP>1</SP> d 2 )<SP>2</SP>, where d<SP>1</SP> = 1/3(d 0  + d 1  + d 2 ), but these signals make no distinction between hills and valleys.

Title: Improvements in and relating to power shovels
IPC: E02F3/30
Filed: 1920-03-15
Abstract: 153,273. Ball Engine Co., (Assignees of Armstrong, E. J.). Oct. 30, 1919, [Convention date]. Jib cranes.-A scoop-arm or other power shovel comprises a rotatable platform, a boom 8 pivoted to the platform and supported by means such as cables 16, and step-by-step mechanism operating the supporting-means to adjust the boom. The stepby-step mechanism is mounted above the cab 5<b> at the head of struts 6 and is operated by a lever 26 depending into the cab. The mechanism comprises a drum 15 secured to a ratchetwheel 20, a pawl lever 22 carrying a pawl 29 and oscillated about a fixed pivot 22<a> by means of the lever 26 to operate the drum and a check pawl 33 mounted on the pivot 22<a>; an adjustable dog 36 is also provided. In the position shown in Fig. 4, dog 36 is inoperative and oscillation of the lever 26 causes the pawl 29 to rotate the ratchet wheel 20 in a clockwise direction to raise the boom. When the mechanism is to be used to control lowering of the boom under load, a trigger 49 is moved to the position shown in Fig. 6 to act through links 47, 45, 42, 41 and spring 38 to move the dog 36 into operative position to engage either the check pawl 33 or a release finger 51 on the pawl 29; the spring 38 acting on dog 36 can overcome either of the springs 32, 35 acting on pawls 29, 33. In this position, as the lever 22 is lowered, the drum rotates in a counterclockwise direction under control of pawl 29 to lower the boom; during this movement, pawl 33, by engagement with the lower surface of the pawl 29, is forced towards the ratchet wheel 20 and release finger 51 slides along dog 36 which forces the pawl 29 outwards when pawl 33 takes up the load. During the upward movement of lever 22, release finger 51 slides along dog 36 and permits the pawl 29 to re-engage the ratchet-wheel and take the load, the dog 36 then forcing the pawl 33 out of engagement. Each of the supporting-cables has one end secured to one of the struts 6 and the other end to a projection 15<a> in the centre of the drum, whereby when the boom is raised the cables are spread to act as braces, while when the boom is lowered, the cables move together to enter a slot 18 in the cab ; the return ends of the cable are connected by lashings 16a so that they also can enter the slot.

Title: Improvements in or relating to magnetic tape recording and playback systems
IPC: G11B5/00
Filed: 1963-02-26
Abstract: 979,497. Suppressing unwanted signals. AMPEX CORPORATION. Feb. 26,1963 [March 19, 1962], No. 7749/63. Heading G5R. Where signal information is frequency modulated and added to a sinusoidal clock-tone for recording, such as is described in Specification 979,496, the non-linearity of the record/playback system may result in modulation products appearing in the signal frequency-band arising from the clock-tone and the FM carrier. These are eliminated by adding an equal and opposite tone to the signal mixture before demodulation after playback. The opposing tone is generated at 10, controlled in level at 28 phase-shifted up to 170 degrees twice in emitter-follower driven stages 18, 20 and a further 180 degrees if needed at 22 before being added to the modulated information signal over an impedance 64. The state of balance is monitored by an oscilloscope 14. Due to the speed-control effected by the clocktone, only a corresponding sinusoidal wave-form is needed to balance out the unwanted tone.
