Patent GB-957404-A (GB)
Title: Improvements in or relating to teleprinter apparatus
IPC: H04L12/06
Filed: 1963-03-29
Abstract: 957,404. Telegraphy. SIEMENS & HALSKE A.G. March 29, 1963 [March 30, 1962], No. 12470/63. Heading H4P. In a telex system, when a station calls a subscriber the subscriber replies with its identity and automatically follows this with a preset message such as " subscriber absent until . . .". The Figure shows part of the subscriber circuitry, consisting of switching unit Fg, telex apparatus Tn, and the automatic call-answering transmitter LS. When a calling signal is received by unit Fg over the exchange line, energization of receiving relay ER causes h1, h2 to be closed and motor M and relay U to be energized. This results in the subscriber sending its identity to the calling station, during which period Ng is closed whereby capacitor C is charged. When the subscriber has stopped transmitting Ng opens and C, in discharging, energizes relays B, V which lock up. Relay V controls the transport of a loop of perforated (or magnetic) tape containing the preset message, preferably preceded by ringing symbols. The preset message is thus sent to the caller, and at the end of the message a particular character results in energization of relay A so that the transport relay V is de-energized. Since B is locked up, b is open so capacitor C can not re-charge when, at the end of message, the calling station and subscriber exchange identities. When the caller sends an end-ofmessage signal, h1, h2 open so that teleprinter motor M is stopped. If desired, instead of providing a contact Ng controlled by the answer-back unit the unit LS may include means for recognizing the WRU calling signal which causes automatic transmission of the preset message after a time delay of about 7 seconds.

Title: Improvements in adhesive applicators
IPC: B65H35/00
Filed: 1969-03-10
Abstract: 1,211,182. Laminating apparatus. WOOD INDUSTRIES Inc. 10 March, 1969 [8 March, 1968], No. 12475/69. Heading B5N. Double-faced pressure-sensitive sheet drawn from a supply roll having a paper backing separating adjacent layers of adhesive sheet is applied to an article by apparatus comprising a rotatable shaft for carrying the supply roll, a rotatable mandrel about which the paper backing stripped from the sheet may be wound, drive means operatively connecting said shaft with said mandrel, and speed-changing means so associated with the drive means that the peripheral speed of the paper backing when being wound on the mandrel is higher than the peripheral speed of adhesive sheet being unwound from the supply roll in order to tension the backing being wound on the mandrel. A rotary shaft 17 supports a roll 18 comprising a web 19 of double-faced pressure-sensitive adhesive interleaved with a web 20 of backing paper. In use, the combined webs are drawn around a roller 23 and over a fired finger 26. The webs are then separated from one another and web 20 is led through the nip of rollers 28 and 29, around a roller 30, and on to a mandrel 31 to be wound thereon into a roll 33, mandrel 31 being mounted on a shaft 31<SP>1</SP> received in vertical slots 32. The surplus portion of web 19 projecting beyond finger 26 is removed thereat, roller 23 is adjusted by screw means 24, 25 to remove wrinkles from the webs passing thereover, and structure 15 supporting the shafts 17, 31<SP>1</SP>, and finger 26 is shifted by a fluid motor 16 until finger 26 engages a printing saddle S releasably secured to a rotary cylinder 5. The latter is then rotated via a driving chain 4, and web 19 is thereby progressively attached to saddle S. A roller 35, driven by engagement with roll 18, is coupled by gearing with roller 29 for driving the latter at a peripheral speed greater than that of web 19 to tension web 20 for stripping the latter from web 19. Roller 29 is coupled by gearing to a roller 41 engaging roll 33 to rotate the latter at a peripheral speed greater than that of web 19 to ensure tight winding of roll 33, shaft 31<SP>1</SP> moving upwardly to accommodate the increasing diameter of roll 33. When saddle S is completely covered by web 19, cylinder 5 is halted and web 19 is severed transversely by a knife 61 mounted on a carrier 62 slidable transversely on a guide bar 63. The free end of web 19 adheres to a strip provided adjacent to nose 26, and motor 16 is actuated to retract nose 26. A carrier 10, slidable on rods 13, is then advanced to engage a thin flexible printing plate P, adjustably secured to carrier 10, with the leading edge of saddle S. Cylinder 5 is then rotated, whereby plate P progressively adheres to saddle S, which is then removed from cylinder 5 for use in a rotary printing press.

Title: Vibrator devices
IPC: B65G27/22
Filed: 1972-03-17
Abstract: 1389068 Vibrators A J WESTWOOD 17 March 1972 12535/72 Heading F2X A vibrator for use with apparatus such as vibratory conveyers comprises a piston 10 slidable in a cylinder 11 in which there are inlet ports 14, 15 and outlet ports 16, 17 through which air or other gaseous fluid under pressure is supplied to and exhausted from the ends of the cylinder 11, the control of fluid flow through the ports being determined by the position of the piston 10 in the cylinder 11. The spacing of the two outlet ports 16, 17 is rather less than the length of the piston 10, so that as shown in Fig. 1, the piston can block both the outlet ports when it is mid-way between the ends of the cylinder. The piston 10 has two L-shaped passages 18, 19, the axially extending portions of which extend to opposite ends of the piston. The spacing of the radial portions of the passages 18, 19 is such that in the position shown, neither of the passages 18, 19 is in direct communication with its associated inlet port 14, 15. The piston 10, however, has an additional passage 20 formed as a groove in its outer surface and communicating with the passage 18, also with the inlet port 14 when the piston is in the position shown. The purpose of this additional passage 20 is to facilitate starting of the device. It is common for the piston 10 to come to rest in the position shown and application of fluid under pressure to inlet ports 14, 15 would create no tendency for the piston to move, were it not for the passage 20 which allows a restricted flow into the passage 18. This in turn causes an increase in pressure at one end of the cylinder, thus moving the piston and beginning the vibrating cycle. The inlet ports 14, 15 are connected by an annular internal groove within the cylinder and the passage 20 which is disposed at an angle to the axis of the piston 10 causes incremental rotation of the piston each time the passage 20 passes the inlet groove. In an alternative construction (Fig. 3, not shown), the additional passage (22) is a groove in the cylinder wall communicating directly with the outlet port 17.

Filed: 1964-03-26
Abstract: 1,010,520. Valves. CONTROLS CO. OF AMERICA. March 26, 1964 [May 31, 1963]. No. 12792/64. Heading F2V. [Also in Division F4] A constant level of liquid fuel for a burner is maintained in a housing 10 by a float operated inlet valve 20 and the flow of fuel to the burner is controlled by an outlet valve 52. The inlet valve is biased by a spring 22 into open position and is held closed by a lever 42. A float 24 actuates a lever 38 pivoted at 36 and having an end (not shown) bearing on a washer 40 resting on a guide member 30 held by a spring 34 in abutment with a nut 28 screwed on to the stem of the valve. The lower end of the spring 34 seats on a cup 32 seated on a flange on the valve stem. When a solenoid 96 is energized by a switch actuated by the temperature at the burner an arm 110 is pivoted in opposition to a spring 100 away from the lever 42 which is therefore moved away from the upper end of the valve stem; the valve is then controlled by the float 24. A further float 50 closes the valve upon the occurrence of an excessive oil level. The outlet valve 52 is biased upwardly by a spring 54 to expose a metering slot 56 beyond the bore of a guide 60. The upward movement may be limited by a stop. When another solenoid 82 is energized by a centrifugal switch on a fan providing air to the burner it lifts an arm 88 in opposition to a spring 86 away from the stem of the valve to allow the valve to open.

Multiple - furrow ploughs; adjusting and lifting parts; wheels, arrangement of. - Lifting and lowering mechanism for ploughs &c. comprises a crank associated with gearing adapted to be operated when desired by the travel of the implement to enable it to be moved angularly for effecting relative movement between the travelling wheels and the frame or part carrying the plough bodies &c., the gearing comprising an internally toothed ring rotatable around the axis of a travelling wheel and engaged by planet pinions in mesh with a gear wheel operatively connected to the wheel, the pinions being carried by a part adapted to impart rotational movement to the shaft carrying the crank. The plough shown is provided with a rear wheel 2 carried by a vertical pillar 3, a furrow wheel 4 carried by a cranked axle 5, and a land wheel 6 carried by a cranked axle 7. The lifting-mechanism forms a self-contained unit in a casing mounted on the cranked part of the axle 7. The gearing in the casing 8 operates a crank shaft 9 the crank pin 11 of which is connected by a link 12 to a relatively fixed pin 13 on the lower end of a depth-regulating lever 14. A gear wheel 17 on the axle 7 is driven for the land wheel 6 by dogs 22 and gears with planet pinions 18, 19 meshing with an internally toothed ring 20 rotatably mounted on the wheel hub 21. The planet pinions 18, 19 are mounted on a flanged gear wheel 26 meshing with a pinion 27 forming part of a disc 28 fixed on the crank shaft 9. The casing 8 comprises a sleeve surrounding the lower part of the axle 7 and is clamped to the upwardly projecting part. An end cover forms a support for the outer end of the double crank arm 10. A roller 31 carried by a pivoted locking-member 32 engages with one or other of two notches 29, 30 in the disc 28. The member 32 is also provided with a projection 34 to engage with one of a number of notches 35 in the toothed ring 20. The arrangement is such that the locking- member 32 releases the ring 20 when it locks the disc 28 fixed on the shaft 9, and locks the ring when it releases the disc, the gearing being inoperative when the ring 20 is free to rotate. The locking-member 32 is operated by a lever 36 linked to an arm 38 moving with a lever 39 adapted to be pulled by a cord to move the lever 36 against the action of a spring 41.

Abstract: 733,392. Projection screens. BEARD, E. G. May 12, 1953 [May 14, 1952], No. 13242/53. Drawings to Specification. Class 97 (1). [Also in Group XXIII] A screen comprises a surface, for example of an opaque or transparent sheet, carrying sets of fine parallel grooves of random spacing and/or cross-section, at least one set being in the form of concentric circles having a centre outside the area of the screen itself. Superposed sets may be applied to a single member or several superposed transparent members may each carry at least one set covering part or all its surface. Where the whole screen is translucent it may be used for rear projection, or may be backed by a mirror. When used for rear projection groups of viewers are located on axes joining the projector to centres of groups of concentric screen grooves. Groups of grooves may be formed by brushes, combs or pads with or without abrasives. A number of such devices may each rotate about a separate centre outside the screen area and may be coupled so as to sweep the whole screen area simultaneously. Some groups of straight grooves may be used or the brushes &c. may have movements about two centres simultaneously to produce a non- circular resultant. By using a comb in conjunction with abrasive there may be. produced grooves of relatively large cross-section with walls carrying finer grooves. Specification 675,364 is referred to.
