Patent GB-480789-A (GB)
Title: Improvements in and relating to variable speed transmission mechanism
IPC: F16H29/18
Filed: 1936-07-31
Abstract: 480,789. Variable - speed gearing. CAVALLO, F. July 31, 1936, No. 21296. Convention date, Aug. 7, 1935. [Class 80 (ii)] Relates to variable-speed gearing of the kind comprising relatively adjustable parallel discs of which one has an annular groove accommodating ratchet members which carry pins engaging radially disposed guide grooves in the other disc. If the guide grooves are strictly radial, only one ratchet at a time is driving and, further, fluctuations of the speed of the driven disc occur due to varying radial distances of the ratchet members. According to the invention, the radial grooves are so shaped and positioned that a plurality of ratchets participate in the drive, and each of such ratchets imparts a constant velocity to the driven disc. The circle 5, with centre O, represents the annular groove, and the circle 2, with centre M, the disc with the guide grooves. For a given eccentricity a, an angular movement w of the driver 2 corresponds to an angular movement w<1> of the driven disc. If these be divided into equal parts 12, 13 &c. and 20, 21, &c., respectively, and radii be drawn from 12, 13 &c., it will be seen that when the ratchet device is at 11<1> it should be at 19, and when at 12<1> it should be at 20 and so on for ensuring constant speed. A lag therefore occurs represented by the distances 11<1>, 19; 12<1>, 20 &c. By setting off these distances from the radius M, 11 along arcs struck through the points 20, 21, &c. a series of points 19, 27-33 is obtained which gives the centre line of a guide groove to produce the result set out above. In effect, the part of the radial groove along which a decrease in velocity occurs is advanced in the direction of motion. The method is approximate, the shape of the curve depending on the eccentricity of the discs.

Patent GB-1457330-A (GB)
Title: Electric digital data processing systems
IPC: G06F12/00
Filed: 1974-05-16
Abstract: 1457330 Data processing INTERNATIONAL BUSINESS MACHINES CORP 16 May 1974 [26 June 1973] 21688/74 Heading G4A In a data processing system having a high speed, last in-first out stack store for storing operands and operators for a processor, and a lower speed store arranged to store overflow copies of the data in the stack, roll in and roll out operations between the store and the stack store merely transfer a copy of a set of stack entries between the two stores and do not delete the entries from the source store. The arrangement reduces the number of roll operations required since, when an entry is to be made into a full stack, a roll out operation is initiated and the new entry overwrites the oldest stack entry which still remains in the stack. Then if a series of entries have to be removed from the stack, a roll-in is not necessary since the old entries still remain in the stack. Similarly following a roll-in operation, which is initiated when an entry is to be removed from the stack which is empty, entries may be entered into the stack overwriting the rolled-in entries without a roll-out operation since the entries being overwritten still remain in the lower speed store. The Specification describes in some detail the procedures involved in tracking the contents of the stack, and in addressing the lower speed store to ensure that the correct stack copies are accessed (roll-in) and the stack contents are copied into the correct locations in the lower speed store (roll-out). To this end three pointers and three status bits are used.

Abstract: 1,141,170. Steering motor vehicles. C. VAN DER LELY N.V. 17 May, 1966 [31 May 1965], No. 21972/66. Headings B7D and B7H. [Also in Division F2] In a tractor having two rear driving wheels 2, 3 and two steerable front wheels 4, 5 controlled by levers 19, 20 arranged one on each side of a driving seat 6 and rotatable with the seat about a vertical axis, each lever being turnable about a horizontal axis, the levers 19, 20 are so coupled with one another via a shaft 22 that when one lever is turned in one direction about its horizontal pivotal axis the other lever is turned in the opposite direction. Shaft 22 has secured to it a depending arm 30 having at its lower end a ball 31 which is received in the socket of a coupling member 33 which is connected by a pivoted rod 57 to an arm 45 fixed to a vertical shaft 44 and coupled to the wheels 4, 5 by linkage including rods 48, 49, the shaft 44 being connected by rack and pinion to the piston of an hydraulic cylinder 42. The member 33 is also connected to a control valve 60 for the cylinder 42 so that movement of a lever 19 or 20 causes movement of member 33 to operate the valve 60 and cause the shaft 44 to be rotated, this movement causing, through rod 57, movement of member 33 to return the ball to its original position. Since this is on the axis of rotation of the seat the latter can be rotated through 180 degrees without disturbing the steering. In a modification (Fig. 8) a piston-rod 95 carries pins 96, 97 which engage in slots 93, 94 of arms 91, 92 extending rearwardly from arms 52, 53 and a coupling member 105 connected to ball 31 has a pin 106 engaging in a slot 107 in the arm of an angle lever 102 having another slot 103 in which engages a pin 104 carried by the outer end of a piston rod 100 of the control valve. The gauge of the front steerable wheels is adjustable.

Title: Process for float glass manufacture
IPC: C03B18/08
Filed: 1968-05-09
Abstract: 1,217,047. Float glass. FORD MOTOR CO. Ltd. 9 May, 1968 [10 May, [967], No. 22005/68. Heading C1M. In the float process float chamber a gas flow is established by drawing which flow is laterally of the ribbon, and in contact therewith to laterally stretch and/or laterally stabilize the ribbon. In the preferred embodiment the ribbon is both laterally stretched and laterally stabilized. The edges of a ribbon of glass 84 (Fig. 2) pass beneath divergent or convergent exhaust tubes 26, 38 with respect to the feed spout and parallel exhaust tubes 28, 40 of a closed circuit gaseous atmosphere circulating system. Each tube has a longitudinal slit, e.g. 62, 64 (Fig. 2) adjacent the ribbon edge. The gaseous atmosphere is fed into float tank headspace through conduits 82. As the gas is drawn laterally across the ribbon surface as shown by arrows 86, 88 to tubes 38, 40 the ribbon is laterally stretched. Simultaneously gas is drawn round the back of the tubes (arrows 90, 92) which creates a partial vacuum between the ribbon edge and the tank side wall. Thus any lateral movement of the ribbon relative to the side-walls is detected by variations in this pressure which automatically changes to stabilize the position of the ribbon. The divergent tubes are used for active lateral stretching and the convergent tubes for passive lateral stretching, i.e. when the gas flow prevents contraction of ribbon width. The tubes 26, 38, 28, 40 are preferably made of carbon or boron nitride. The drawn off gas is cooled before re-entering the tank through conduit 82. Reference has been directed by the Comptroller to Specification 1,173,656.

Abstract: 1,151,456. Reducing electrostatic charges in liquids flowing through pipes. STANDARD OIL CO. 12 May, 1967 [18 May, 1966], No. 22058/67. Heading F2P.  Apparatus for reducing electrostatic charges in an electrically charged liquid, e.g. military jet fuel which has a relatively low electric conductivity, comprises a capacitor, consisting of a tubular metallic grounded outer cylinder 10, a dielectric 12 of thick, non-conductive, material 12, e.g. polyethylene, polystyrene, of high resistivity and low dielectric constant fixed within said outer cylinder 10, the dielectric having a hollow core the surface of which acts as the other plate of the capacitor, and a plurality of sharply pointed grounded electrodes 14 which are spaced apart axially and have points which slightly protrude into said hollow core, so that liquid having an electrical charge flowing through the hollow core, will contact the points. It is stated that positioning a sharp grounded point in the liquid in a region of high voltage causes an intense electric voltage gradient to be set up in the vicinity of the point to ionize liquid molecules which are of opposite sign to the charged liquid to neutralize the latter. Successive neutralization points reduce the charge of the liquid to a point where it no longer presents a hazard. The internal diameter of the dielectric 12 should match that of the piping in which it is installed so that smooth surfaces are provided at the junctions. As the internal diameter of the dielectric is increased so should its thickness be increased in order to decrease the capacity as the size of the capacitor increases, the small capacity being essential for a short starting transient time before the device becomes effective as liquid commences to flow through the capacitor. The electrodes are arranged in axially-spaced circumferential rows, the electrodes of one row preferably being offset from an adjacent row by 60 degrees and the rows being spaced by an amount which allows mixing of the charge in the liquid and the injected charge before the additional charge is injected. The number of rows is from about 3 to 5. As shown, each electrode comprises a bolt 18 which is threaded into an adaptor ring 24 welded to the cylinder 10 and which carries a pointed electrode 16 which is formed of a hard, non-corroding precious metal, e.g. osmium, the point having a radius of 2-3 mils. A continuous spiral groove in the back of the dielectric 12 forms a keying surface for an epoxy cement used to fix the dielectric 12 to the cylinder 10.
