Title: Device for applying strips to wrappers
IPC: B31B1/90
Filed: 1953-08-24
Abstract: 734,910. Wrapping-machines. PACKAGE MACHINERY CO. Aug. 24, 1953 [Jan. 16, 1953], No. 23268/53. Class 94 (1). [Also in Groups XV and XVI] In a wrapping-machine in which the wrappers are provided with tearing strips, a web of tearing strip t is fed by rollers 33, 34 through a groove I in a pivoted guide block 10 and over a roller 12 which applies adhesive to the underside thereof, the block 10 being swung about its pivot 40 periodically by a camoperated arm 39 to lift the web from the roller so that spaced portions thereof are left free of adhesive. The upper surface of the web is then engaged by the run of a perforated end less belt 13 which travels in engagement with the slotted under surface of a suction box 15, the suction applied through the perforations holding the web against the belt. A bar 17 carried by a spring-loaded arm 18 is arranged to hold the web away from the belt while a rotary knife 19 cuts through the portions which are free of adhesive. The belt is driven at a greater speed than the rollers 33, 34 so that slip occurs between the belt and web prior to the severing operation and the severed tearing strips are spaced one from another on the belt. A web w of wrapping material is fed over guide rollers 65-68 so as to pass transversely and substantially horizontally below the lower run of the belt 13, and as each tearing strip is positioned over the web, the latter is lifted into contact therewith by a roller 20, carried by cam-operated arms, so that the strip is adhesively secured to the web and removed from the belt. The web w is formed with slits 80, Fig. 13, at intervals by knives 82 and the tearing strips are attached between the slits. The web t passes from a supply roll 21 between adjustable tensioning members 24, 25 and then through a heated ironing device 27-29 which removes twist or curl. The timing of the various mechanisms is adjustable to vary the length of the tearing strips cut from the web.

Title: Improvements in or relating to the separation of the components of mixtures
IPC: B01D11/04
Filed: 1951-10-10
Abstract: <PICT:0707919/IV (b)/1> <PICT:0707919/IV (b)/2> In the separation of mixtures of substances' e.g. proteins or amino-acids, by distribution between two immiscible phases, the mixture is introduced into at least one of the phases and the two phases are brought into intimate contact for the purpose of adjusting the partition equilibrium in a plurality of adjacent chambers communicating with each other through apertures, whilst maintaining a substantially uninterrupted phase boundary in the individual chambers, the portions of the phases in contact at the phase boundary surfaces being continuously renewed in the individual chambers by maintaining a constant movement within the individual phases, at least one of the phases being allowed to flow in horizontal direction from one chamber to the next.  As shown in Fig. 1, a heavy phase 3 and a light phase 4 continuously flow in countercurrent through a slowly rotating horizontal cylinder 1 subdivided into a plurality of chambers of transverse partitions 2 provided with small apertures 2a.  The mixture to be separated is continuously introduced into the central chamber through a funnel 11. The slow rotation of the cylinder causes a continuous intensive formation of the boundary face between the two phases without producing an emulsification of the two phases. As an alternative, the cylinder may be stationary, the stirring being effected by rotating discs.  In the modification shown in Fig. 9, the mixture to be separated, dissolved in the heavier phase, is introduced into a container 15 and is allowed to flow via a pipe 16 into the first chamber of cylinder 1 and is then pumped out of this chamber via a pipe 17 back into container 15. The cylinder 1 is continuously traversed from the last chamber to the first by fresh quantities of the heavier phase so that the total volume of liquid circulating through chamber 15 is increased.  Means (not shown) for continuously removing (e.g. by evaporation) solvent from the circulating phase is provided.  The second (light) phase continuously flows from the first chamber to the last.  Examples describe the separation of a mixture of leucine and valine with butanol and water or phenol and water, the separation of casein into a - and b -casein with a two-phase system made by mixing water, glacial acetic acid, phenol and acetylene tetrachloride; and the extraction of protein hydrolysates with butanol/water or phenol/water.

Title: Improvements in or relating to the suspension of electric cables
Inventor: SMART WILLIAM HENRY JAMES
IPC: H02G7/10
Filed: 1955-08-17
Abstract: 798,699. Erecting cables. BRITISH RELAY WIRELESS, Ltd. Aug. 17, 1956 [Aug. 17, 1955], No. 23683/55. Class 36. Electric cables are lashed to a catenary wire by putting a coil of binding wire loosely around the cables and catenary, securing one end, then extending the coil until the turns bind tightly around the cables and catenary. A machine for this purpose comprises a forming head 23 to juxtapose the cables and catenary wire, a carrier 20 and 21 for the binding wire, and an extruder 22 through which cables 11 (not shown in Fig. 1) catenary 10 and binding wire 12 pass in such a way that the wire binds around the cables and catenary as the machine is moved in the direction indicated by the arrow " C " in Fig. 2. The carrier consists of an inner cylinder 20, which is longitudinally split and hinged to pass around the cables, and an outer cylinder 21 having a longitudinal gap for the same purpose. The binding wire 12 is engaged in a hole 25 at one end, wound around the inner cylinder, and the outer cylinder is slipped over it. The forming head comprises a partial cylinder 48 secured around the end of the outer cylinder by a hinged screw-clip 50 and extended to form two side plates which carry horizontal rollers 63 to 67 and 69 to 72 and have brackets carrying vertical rollers 55 to 60. Some of the rollers are adjustably mounted in slots and some are hinged at one end so that they may be swung open, as, e.g., roller 67 in Fig. 2, to enable the forming head to be fitted into position around the cables which are spaced apart by the rollers. A bracket 30 is also fitted and carries a wheel 31 to travel along the catenary wire. The extruder comprises several resilient rubber discs 40 slit from the centre to the lower edge, with short radial slits extending part way from the centre to the edge, and having central apertures to allow passage of the cables. A split steel washer 39 is bolted to one end of the rubber disc assembly and a leather washer 43 to the other end, whilst attached to the steel washer are projecting lugs 44 which may be grasped and pulled apart thus opening up the washers and discs which can then be placed around the cables. A part cylinder 36 is attached to the washer 39, fits over the cylinder 21 and is locked by a bayonet coupling 37 and 38. A steel reinforcing ring 34 fits inside the end of cylinder 21 and buts against the leather washer 43 whilst a rubber ring 35 fits between the steel ring and the end of the inner cylinder 20 and is so dimensioned and tapered internally that the binding wire is restrained and thus drawn off the cylinder evenly. A collector plate to be used in conjunction with the forming head to reverse the binding process and collect the wire into a coil as it unwinds is described.

Patent GB-669031-A (GB)
Title: Improvements in pulse discriminating circuits
IPC: G01R29/027
Filed: 1947-08-28
Abstract: 669,031. Pulse discriminating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 28, 1947 [Aug. 28, 1946], No. 23802/47. Class 40 (vi). A circuit for discriminating between pulses of different duration comprises means for differentiating the pulses and applying the differentiated pulses directly and via a delaying means to the two control electrodes respectively of a control device which only passes current when the voltages applied to its control electrodes occur simultaneously and have a given polarity. In this way an output pulse is obtained only when pulses are applied to the input whose duration is equal to the delay introduced by the delaying means. The discriminator may be used to improve the signal-to-noise ratio in pulse communication or object detecting systems. Fig. 1 shows a discriminator in which negative-going input pulses applied from unit 1 are differentiated by network 2, 3 and applied to control electrode 5 of valve 4 and in which the input pulses are also differentiated by network 9, 10, phase reversed and applied via the delay network 11 to the second control electrode 14 of valve 4. When a negativegoing input pulse is applied which has a duration equal to the delay introduced by network 11, positive-going pulses are applied simultaneously to the two control electrodes of valve 4, the two sections of the valve are both rendered conducting and a negative-going pulse is applied to the utilizing device 24. In a modification, Fig. 6 (not shown), for use with positive-going input pulses, a differentiated and phase-reversed pulse is applied directly to one control electrode of the valve 4 and a differentiated input pulse is applied to the other control electrode via a delay network. Specification 610,655 is referred to.

Title: Improvements in or relating to cathode ray tubes and the like
IPC: H01J29/43
Filed: 1932-08-25
Abstract: 406,353. Cathode-ray tubes; photoelectric cells. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, TEDHAM, W. F., 267, Woolwich Road, Abbey Wood, and McGEE, J. D., 184, Haverstock Hill, both in London. Aug. 25, 1932, No. 23841. [Class 39 (i).] A cathode-ray tube for use in television or a photo-electric cell contains an electrode the construction of which comprises the step of depositing a substance thereon through a screen such as a wire mesh in order to obtain a number of insulated photo-electric elements. The photo-electric electrode 3, Fig. 1, comprises a glass disc mounted at an angle of forty-five degrees to the axis of the tube. It is coated on one side with a conducting layer and is provided on the other side, by means of clips, with a mesh 4 of three hundred lines to the inch. The narrow portion 5 of the tube is provided with a tungsten helix carrying a silver pellet. The tube is exhausted and a current passed through the helix to vaporize the silver on to the glass plate and at the same time the tube is cooled by a surrounding layer of cotton wool on to which liquid air is poured. The helix and the screen are removed, and the tube is baked and evacuated and the silver deposits are then oxidized by passing a highfrequency discharge in oxygen at a pressure of 0.3 mm. Excess oxygen is removed and caesium is distilled over on to the oxidized silver elements from a side tube containing calcium turnings and caesium bromide powder. The introduction of the caesium is carried out in stages, the tube being baked between each stage. In a modification, the elements are formed on an oxide coating on a metal plate such as an aluminium plate 11, Figs. 5 and 6, at least one face of which is oxidized by making the disc the anode of an electrolytic cell containing chromic acid. The thickness of the coating should be about 0.002 ins. The disc is mounted through wires 12, 13 upon a pinch 14. A ring 17, formed in the same way as the elements, facilitates testing of the photo-electric material. The elements may be square or circular in shape. The conducting layer of the electrode is connected through a condenser to the grid of an amplifying valve and through a resistance to earth.

Filed: 1975-09-01
Abstract: 1514913 Fluid-operated vibrator E FENTON 1 Sept 1975 [30 May 1974 13 June 1974] 23923/74 and 26186/74 Heading F1M In a piston-cylinder fluid vibrator of the type where the piston 42 co-operates with inlet and exhaust ports 47, 49 in the cylinder 43 to supply pressurized fluid alternately to each of the two cylinder chambers defined by the piston to cause the piston to oscillate, the exhaust ports 49 are in communication with an expansion chamber comprising an axially extending cylindrical bore 30 in the wall of the vibrator, and this chamber communicates with a fluid outlet 34 extending radially from the wall. The expansion chamber enables the pressure differential between the cylinder chambers to be more rapidly established. The inlet ports 47 are in communication with a reservoir chamber 46 supplied from a fluid source along pipe 48. The piston 42 has two circumferential grooves 44 which communicate via axial grooves 45 with the cylinder chambers, and are brought into communication with the inlet ports 47 as the piston oscillates. In the position shown the piston closes off both inlet and both outlet ports. If the piston is moving to the left, fluid is supplied to the left hand chamber and exhausted from the right hand chamber to the expansion chamber 30 and outlet pipe 34. The piston therefore rebounds to the right causing fluid to be supplied to the right hand chamber and exhausted from the left hand chamber. In the embodiment of Fig. 2 (not shown), there is no reservoir chamber supplying the inlet ports and the fluid supply pipe (14) communicates directly with a single circumferential groove (13) in the piston. This groove communicates (depending on piston position) with one of the two inlet ports, which communicate with the cylinder chambers (19, 20) via axial passages (15) in the cylinder wall. The exhaust ports (17) communicate with an expansion chamber (16).  These vibrators provide a rapid deceleration of the piston at the ends of its stroke, resulting in a more rounded (approximately sinusoidal) waveform for the vibration than is usual. The vibrator is used to vibrate a bowl feeder.
