Abstract: 803,497. Applying adhesive tape. RAPINWAX PAPER CO. June 18. 1956 '[June 29, 1955], No. 18774/56. Class 73 [Also in Group XVII] A device for applying a reinforcing band to a web of wrapping material comprises a yoke 19 which is pivotally mounted for rotation about a vertical axis and supports a shaft 21 carrying a guide roller 36 and spaced arms 22 interconnected at their outer ends by a guide bar or roller 24. A pressure roller 27 is rotatable in bearings 25 resiliently mounted on the arms 22, and an electrically-heated roller 31 is carried by arms 30 pivoted on the bar 24. The arms 30 carry stops 32 engageable with the ends or upper surfaces of the arms 22 to support the roller 31 in the alternative positions shown in Figs. 1 and 6. If the roller 31 is positioned as shown in Fig. 1, a roll 12 of wrapping material is mounted on a rotatable support 11 so that a web W may be drawn from its underside and fed to a wrapping machine. Banding material B coated on both sides with a heat-sensitive adhesive is drawn from a roll 15. mounted on a similar support 14, and threaded over the roller 36, under the roller 24, over and around the heated roller 31 and between the pressure roller 27 and the roll 12 so that the wrapping machine is supplied with the web W having the thin forcing band adhered to its underside. If the roller 31 is positioned as shown in Fig. 6, the roll 12 is reversed so that the web is drawn from its upper side, the banding material being threaded over the rollers 36 and 31 and applied to the upper side of the web by the roller 27. The weight of the arms 22 and associated parts is partially supported by a spring 38 connected between one of a series of pins 40 on the yoke 19 and one of a series of pins 39 on an arm 37 secured to the shaft 21, the pressure applied by the roller 27 being variable by changing the position of the spring. The shaft 21 may be rotated by a hand crank 41 to raise the arms 22 to an inoperative position in which they may be retained by a ratchet 43 on the shaft co-operating with a pawl 44 pivoted to the yoke 19. The vertical pivot 20 of the yoke enables the device to be swung to one side for cleaning purposes.

Title: Improvements relating to frame scanning circuits for television and like apparatus
Inventor: WHITE ROBERT CYRIL
IPC: H04N5/12
Filed: 1949-07-19
Abstract: 679,125. Television receivers. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 12, 1950 [July 19, 1949], No. 18920/49. Class 40 (iii). In a television circuit arrangement for interlaced scanning, the instants of termination of each forward stroke and the initiation of the next forward stroke of the frame scanning sawtooth-wave generator are both determined by different portions of the frame-synchronizing signal of slotted form, Fig. 2 (a), the initiation of the forward stroke being controlled directly by the leading edge of one of the frame synchronizing pulses 30. In the arrangement shown in Fig. 1, the demodulated incoming signal is applied to a pentode 3 which only conducts on synchronizing signals. Its output, Fig. 2a, is integrated by network 4, 5 and applied to a valve 6 biased to anode-current saturation so that only the broad frame-synchronizing pulses produce a positive excursion, Fig. 2b, which is fed to the control grid of valve 8 forming, with valve 7, a multi-vibrator producing the frame-deflecting saw-tooth wave across a condenser 18. During the intervals between frame-synchronizing signals, valve 7 is conducting and valve 8 is held non-conducting by the charge on condenser 9 which gradually leaks away so that at the instant 32, Fig. 2b, valve 8 becomes conducting. The increased potential at the anode of valve 7 renders diode 11 conducting; condenser 9 changes rapidly through it and resistance 10, and the potential on the control grids of valves 7, 8 is prepared for a further change-over. The wave shown in Fig. 2a is also applied from the screen grid of valve 3, through a differentiating circuit 20, 21 producing pulses 33, 34, Fig. 2c, to a valve 22 which passes only the negative pulses 34 inverted to positive form, Fig. 2d, to the control grid of valve 7. The last of a predetermined number of these pulses switches valve 7 on to commence the next forward stroke. An even number of leading edges of the pulses 30 occurs between the times of terminating one forward stroke and initiating the next so that the number of line-return strokes during each frame-return stroke is the same in alternate frames. Specification 455,375 is referred to.

Abstract: 1,070,521. Delivering measured quantities of powder. BECORIT (RESEARCH) Ltd. May 4, 1965 [May 7, 1964], No. 18958/64. Heading B8N. An apparatus for dispensing measured quantities of powder to the foot of a person comprises a container 14 for the powder and a dispensing means for delivering a measured quantity of powder in response to actuation of an operating plunger 28. The container 14 is provided with an outlet 16 closed by a closure member 18 which is connected to the operating plunger 28 via rods 22, lever 25 and a stirrup 27. A groove 19 is formed in the closure member 18 so that when the plunger is moved downwardly the closure member is raised, thereby allowing powder to flow into the groove; upon release of the plunger, the closure member drops so as to dispense the powder from the groove on to a person's foot resting on a tray 13. In a modification (Fig. 4), the dispensing operation is effected by placing a foot on to a pedal (65) connected to the closure member (59) by rods (64), the closure member returning under the action of a spring 63.

Title: Improvements in self adjusting tappets
IPC: F01L1/22
Filed: 1954-06-29
Abstract: 747,161. Tappets. SHEPHERD, G. H. June 29, 1954, No. 19094/54. Class 80(3) In cam mechanism wherein a self-adjusting tappet T, Fig. 1, is interposed between a rotating cam d and a reciprocating driven member which is returned by a spring to a stop or seating, such as the valve of an internal combustion engine, the tappet T is slidably keyed against rotation and has screwed therein a head b connected to a torsion spring c which unscrews the head until it bears on a ring f on the cam shaft. Should the tappet head become too far unscrewed, thereby preventing the correct seating of the driven member, the spring loading of the driven member is transferred to the ring f, and the frictional engagement between the head and the rotating ring screws up the head until the driven member is correctly seated. The spring may be contained in a barrel, in the manner of a clock spring. In the valve mechanism shown in Fig. 4 the mass of the reciprocating parts is reduced by mounting the torsion spring in a barrel g on an arbour n which is geared at p to the tappet head b. The barrel g is latched on a pawl p to allow adjustment of the spring torsion. In manufacture, the parts are assembled with the head partly unscrewed and the cashaft then rotated to wind up the torsion spring.

Title: Directive antenna system
IPC: G01S3/08
Filed: 1945-07-26
Abstract: 596,479. Aerials; radio directionfinding. STANDARD TELEPHONES & CABLES, Ltd. July 26, 1945, No. 19227. Convention date, June 2, 1942. [Class 40 (v)] Relates to means for reducing the errors caused by the undesired reception of horizontally polarized waves in a directive aerial comprising one or more pairs of spaced aerial elements responsive to vertically polarized waves, the elements of each pair being differentially coupled, e.g. Adcock or spaced loop systems. According to the invention, the elements of a pair A, B, Fig. 5, are differentially coupled by a screened transmission line comprising two parallel portions 32, 34 extending at right angles to the plane of the elements and coupled together by a third portion 36 at a distance from the aerial such that the parasitic induction produced in the elements by the electrical forces present in the shield of the third portion is negligible ; a suitable distance is one and a half times the element spacing. The field pattern of reception of the horizontally polarized waves by the transmission line shield is then due to the parallel portions 32, 34 only and will be oriented similarly to the aerial reception pattern for the vertically polarized waves, Fig. 6 (not shown). The induction effect of the transmission line portions 32, 34 is reduced by the earthed circular screens 24a, 24b, and the effect may be balanced, Fig. 10, by providing two symmetrical transmission lines 70 and 71 for the elements C and D. In Fig. 12 (not shown), the parallel portions of the transmission line are folded back so that the third portion is in the plane of the elements. The aerial elements may be unipoles or dipoles or coplanar loops, Fig. 14 (not shown), coupled to the transmission line by transformers or valve couplings and the invention is applicable to a single rotatable pair of elements or to fixed crossed pairs operating with a goniometer ; in the latter case the transmission lines may be buried.

[Also in Divisions F2 and G3] Mechanism for controlling the speed of a motor-driven shaft comprises meshing toothed sectors 5, 6, the sector 5 being secured to a shaft 7, to which a bush-rocker 2 of the motor 1 is attached, and the sector 6 being rotatably mounted by means of a shaft 9, on a lever 11 which is pivotally mounted on shaft 7 and is attached to an hydraulic damping member 10. The sector 6 is biased to a neutral position by a leaf spring 12 and is coupled by a link 15 to a knee lever 14 carrying a roller 4 around which passes a web 3 of paper, the tension of which it is desired to maintain constant. If the tension of the web 3 increases slowly, sectors 5, 6 and lever 11 rotate in unison anticlockwise thereby effecting rotation of shaft 7 and gradual regulation of the motor speed. If, however, the displacement of link 15 occurs rapidly, there is relative rotation between the gear sectors 5, 6 causing a rapid acceleration of the motor and flexing of the spring 12 which then causes anticlockwise rotation of lever arm 11 and restoration of the gear sectors 5, 6 to their original relative positions, Fig. 4 (not shown) with consequent adjustment of the motor speed. In a modification, the gear sectors 5, 6 are replaced by a pin 16 on a link 18 secured to shaft 7 engages a radial slot 18 in a link 19 secured to shaft 9, Fig. 5 (not shown).
