Patent GB-156267-A (GB)
Title: Improvements in or relating to servomotors
IPC: G05D3/12
Filed: 1917-11-22
Abstract: 156,267. Weismann, C. Nov. 22, 1916, [Convention date]. Steering and manoeuvring automatically. - A servo-motor comprises a clutch member adapted to be coupled to a continuously moving part when an electric circuit is completed through a contact carried by the clutch member and a brush connected to the control element, the brush and the contact moving over a series of contacts arranged in a circular track so that movement of the clutch member causes the contact to break the circuit again at the point determined by the adjusted position of the brush. The servo-motor may be used for operating steering-gear under the control of a gyroscope or magnetic needle. Fig. 2 shows diagrammatically a servo-motor adapted to operate in either direction, the clutch member being shown displaced from its position coaxial with the contact circle. A brush b carried by a pin d connected to the control element moves over the inner surface of a ring of insulated contacts a, on the outside of which move contacts l, l<1> carried by the clutch member. The clutch member comprises two opposed ratchet wheels e, e<1> mounted on a shaft d‹ coaxial with the pin d and connected to the part to be operated. A lever f, continuously vibrated by an eccentric g on a shaft h, carries two pawls i, i<1> which are normally held out of engagement with the ratchet-wheels e, e<1> by springs j, j<1>, but are adapted to co-operate with them when electromagnets k, k<1> are energized. When the brush b, which normally lies between the contacts l, l<1>, is moved beneath one of them, a circuit is completed which energizes one or other of the electromagnets k, k<1>, either directly or through the relay devices q, q<1> which permit of a smaller current through the brush b. The movement continues until the contact is no longer opposite the brush. To prevent the circuit from being broken by the brush over-running the contact l or l<1>, the latter are preferably extended to cover several of the ring contacts a. When used on aircraft under control of a Bourdon-tube type barometer, the shaft h may be driven by the engine or by a wind vane. A single direction motor is described having only one ratchet wheel, pawl, electromagnet, and contact. The brush b is preferably rendered non-oxidizable by being plated with platinum. The ring contacts a may be of magnetic material and the brush b a small magnet so as to increase the pressure of contact; or the brush may be permanently clear of the contacts and a high-tension current used, in which case the insulation between the contacts a projects slightly inwards. A modification is described in which a reversible electromotor is used instead of the clutch member to drive a wormwheel carrying the contacts l, l<1>. Preferably the electromotor remains always excited, the armature being short-circuited when the armatures of the relays q, q<1> are released.

Abstract: 745,752. Cigarette-making machines. FILTER TIPS, Ltd. June 23, 1954 [June 26, 1953; Aug. 19, 1953], Nos. 17818/53 and 22902/53. Class 130. A uniting band is wrapped around an assembly of a double length stub and flanking cigarette rod lengths, partly by rolling the assembly on the band while the band is supported on a surface and partly by moving the assembly laterally towards an abutment extending from the surface to press an end portion of the band against the abutment and assembly. A stub may include filtering material, a hollow tube and/or tobacco differing from that of the cigarette rod lengths. Uniting bands B, cut by knives 4 from a web 2 forwarded on a suction drum 1, have their leading ends wrapped round assemblies A by relative movement between the assemblies A and slides 9, laterally of the assemblies and whilst they are not rotated, wrapping being continued by rolling of the assemblies rearwardly on the drum 1 due to their co-action with a ramp 14, and completed by relative movement between the assemblies and the slides 9 behind them, laterally of the assemblies, as they roll into contact with these slides. The knives 4 are mounted in a rotary member 3 and spring-urged radially outwardly to co-act with hard ends of the slides 9. Suction is applied to an annular chamber 5, partitioned by the slides 9, via holes in a fixed wall end 7 which extend round the chamber 5 only to the position where the slides 9 are radially projected from the drum 1 under the action of a stationary cam 11 to cause the relative movement for leading- end wrapping, at which position suction is consequently cut off. The assemblies A are deposited on the bands B by arms 12 of a rotating spider, as suction through ports 13 is cut off. The wrapped assemblies are delivered by a guide 15 to a conveyer 16 and are divided into individual composite cigarettes. In a modification, the slides are dispensed with, the assemblies merely picking up bands from the drum and the spider further transferring the assemblies and bands to means comprising a second drum, an endless chain conveyer or, according to the second Provisional Specification, an endless belt conveyer, and having fixed teeth which act in the manner of the slides as the assemblies and bands pass to and beneath a ramp as before. The spacing of the fixed teeth may be sufficient for completion of wrapping by rolling before the assemblies contact the teeth behind them, or for the teeth before them not to contact them at all. According to the first Provisional Specification, the uniting bands may be of cork or replaced by spraying of the assemblies with adhesive, the slides may have arcuate grooves which receive the assemblies, and the ramp and slides may be slotted to receive a rotary circular knife dividing the assemblies. According to the second Provisional Specification, the ramp may be replaced by a movable surface.
