Title: Improvements in and relating to pneumatic springs or shock absorbers
IPC: B62J1/26
Filed: 1920-06-04
Abstract: 162,289. Seibel, H. May 7, 1917, [Convention date]. Pneumatic springs. - Consists of a pneumatic spring including a frame forming a chamber having an opening, a pneumatic casing secured to the frame and covering the opening and bulging outwardly to form an extension of the chamber, and a pneumatic inner tube in the chamber and extension. The invention is described as applied to a motor-cycle saddle, one or more pneumatic supports being arranged between the saddle top and a frame bracket 14, the bladders 35 being integral with a reservoir 46 fitted with an inflating valve and secured by a casing to the saddle. The covering 34, made of rubber and fabric, is Banged at 40, the support being secured to the casing by a flanged ring 41 and bolts 44. The neck is stiffened by a metal ring 47 held by an inner liner 48. At the lower end, a deforming member 37 on the bracket 14 engages a pressed-in part 36 of the support. Specification 144,311 is referred to.
Patent GB-1171422-A (GB)
Title: Improvements in or relating to Multiple Station Intercommunication Systems
IPC: H04L12/18
Filed: 1968-03-12
Abstract: 1,171,422. Signalling between a number of stations. HAVALEX Inc. 12 March, 1968 [17 March, 1967], No. 11943/68. Heading G4H. In a system in which a number of stations communicate with each other, each station having one of two conditions and having display means to indicate the conditions of all the other stations, each station has a bi-stable storage device for each station in the system, each storage device being coupled to a corresponding display lamp. The stations may be hotels and the condition to be indicated may be whether or not there are vacancies. At each hotel the vacancy indicator consists of a housing having an array of panels on the front, each corresponding to one of the hotels and being illuminated to indicate that there are vacancies. A switch S 1 on the housing is operated to indicate that there are or are not vacancies in the hotel where it is installed. In each housing is a scanner comprising a rotatable switch arm 18 driven through a single-revolution by motor 43 under the control of a gapped contact ring 14. The outer contact 22 on arm 18 connects ring 13, to which telephone wires are connected, and a series of contacts 1, 2, 3 . . . 30. The contact 23 is a home contact. Each contact except 23 is connected to a storage unit comprising a silicon controlled rectifier triggered by transistor 24 and adapted, when conducting, to light lamp 11. When a switch S1 is operated, a signal is applied to the number 1 contact to light the corresponding lamp. Other contacts of switch S1 connect capacitor 36 across a relay 31 which closes contacts 29 briefly to energize the home contact 23 and operate relay 27 closing contacts 28 and opening contacts 26. These latter contacts reset all the storage devices. Contacts 28 cause the motor relay 21, 41 to operate and the motor starts. The start signal on contact 23 is transmitted to all the other stations to cause scanning to start in synchronism. When the contact arm 18 moves to contact 1, energized by switch S1, this signal is transmitted to all the other stations and causes the appropriate bi-stables to be set. When the contact arm 18 reaches contact 2 the action is opposite, a signal coming from another station over the telephone line is applied to set the corresponding storage element. Subsequent steps are the same. When the contact arm 18 reaches contact 23 contact 19 is in the gap 17 of ring 14 and the motor stops. The stores remain set and the lamps lit until another vacancy switch is operated. Scanning can be initiated at at any time by switch S2.

Title: Improvements in or relating to machines adapted for use in the manufacture of ceramic ware
Inventor: BRADSHAW ARTHUR
IPC: B28B1/02
Filed: 1969-03-07
Abstract: 1,268,521. Ceramic turning machine. SERVICE (ENGS.) Ltd. 6 March, 1970 [7 March, 1969], No. 12067/69. Heading C1H. A machine for turning clay in the manufacture of ceramic ware comprises a rotatable mould support 26, tool supporting means 30 for a rotatable roller shaping tool 28 and means for causing the mould support 26 to be raised towards tool 28 to a distance which determines the thickness of the ceramic article, and means for adjusting the height of the tool supporting means. The mould support 26 comprises a cup-shaped annulus 40 carrying the mould M on which clay P is placed, and is mounted for vertical and rotating movement on spindle 46. Oscillatory vertical movement is caused by cams 88 actuating lever 78 at roller 86 which engage pins 72 attached to a boss 72 enclosing the spindle 72. Rotating motion is provided through a clutch operated pulley 126 freely rotatable on spindle 46 and driven from a variable radius pulley 140 on a motor 142 by belt 138. Cam 166, via lever 160 and follower 164 causes the drive from driven pulley 126 to be transmitted via clutch plates 136 to spindle 46 only at that part of the cycle when clay is being actually turned. Cam 88 contains arcuate slots 94 through which its relative position with respect to the flanged collar 96 can be adjusted and held via bolts 92, enabling the plane of the cam to be changed, or a new cam fitted. The roller shaping tool 28 comprises a circular plate having a conical stub 182 fitting into a recess in rotatable shaft 188 and held in that position by bolt 186 passing through the centre of shaft 188. Electric cartridge heaters 200 are provided in the tool and are powered from slip rings 216. Shaft 188 is driven from a motor (384) via belt 388 and variable radius pulley 390, the displacement of which is controlled by lever 400 and speed adjustment screw 410. The height of the tool 28 is adjustable via a threaded bolt 270 and sliding boss 272 arrangement. The whole head 30 is mounted on shaft 276 which can be raised or lowered by knob 314 acting through gears 310 and 308 and threaded bolts 304, and rocked about its longitudinal axis which is at right angles to the axis of rotation of the mould support by a bushed lever 334 incorporating a worm gear sector 342 meshing with a manually operated worm 354 by which the position of the head 30 relative to the vertical can be adjusted on loosening nuts 348. A motor-driven cam 362, adjustable as cam 88, oscillates the lever 336 via slide 366 and extension 372. A trimming tool is mounted on vertical shaft 432 and arranged for axial reciprocation by driven cam 438.

Abstract: 148,273. Desmoulins, E. July 19, 1919, [Convention date]. Motor power plant.-Relates to a combination of reciprocating internal-combustion engines, the members of the combination differing in power and acting separately or together, and is chiefly applicable to automobiles. A<1> and A<2> are internal-combustion engines, the former of low power and the latter of high power. Each operates an independent shaft a<1> and a<2>. The engine A<1> actuates a clutch member b<1>, the other member d<10> of which is carried by a sleeve f<1> on the main shaft c. The other end of this sleeve carries the central pinion f of an epicyclic gear shown. The planet-pinions g of this gearing are carried by a sleeve h on the sleeve f<1>. The engine A<2> actuates, similarly to the engine A<1>, a sleeve j<2> on the sleeve h, and the sleeve j<2> carries the annular pinion j of the epicyclic gear. The gears f, g carry one clutch member i, the other member k being mounted on a sleeve splined on the shaft c. The member k is also a member of an outer clutch, the other member k<0> of which slides on the sleeve last-mentioned. The member k<0> is in slidable connexion with the gear j. All the clutches are acted on by springs which tend to keep them in operative engagement. The engine clutches are operated by a lever s by which either or both engines can be put in gear. The remaining clutches are actuated by foot levers t and v, which also actuate brakes n and m respectively. A third brake l is actuated by a foot-lever x. By means of the epicyclic gearing, and by using either engine separately, or both together, five different speeds may be obtained. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification wherein the shafts a<1>, a<2> are parallel instead of co-axial, and it is stated that change-speed mechanism of the kind described in Specification 148,272, [Class 80 (ii), Gearing, Variable-speed &c.], may be used with the invention.
