Title: Improvements in or relating to change speed gears for motor cars and other power driven vehicles
IPC: F16H61/662
Filed: 1920-08-11
Abstract: 173,813. Santis, S. de. Aug. 11, 1920. Variable-speed friction gearing. - In friction disc-and-roller gearing for motor vehicles, of the kind in which the axis of the roller is moved in a plane parallel to the face of the disc to cause the roller to slide automatically along its shaft to vary the speed, the movement of the roller axis is effected automatically when the balance between the driving and the resisting forces is disturbed. The roller P, Fig. 3, slides on its shaft A, which can rock in a plane parallel to the face of the disc D, this movement being controlled by a spring R. When the vehicle is to be started, the roller P is near the centre of the disc, and the shaft A, under the influence of the spring and of the load resistance, takes up a balancing position such as that shown, in which the roller tends to move toward the periphery of the disc. The gear is thus raised until a balance is effected and the shaft A moves into a plane containing the axis of the disc shaft 0. An increase or decrease of resistance then causes the shaft to move down or up to decrease or increase the gear. The gearing may be applied to a vehicle, as shown in Fig. 4, in which the driving-shaft 0 carries two discs, either of which may be engaged with two rollers P, P<1> for forward and reverse driving. The shaft 0 slides axially to effect this engagement and is controlled by a spring F and a pedal N. The rollers P, P' rotate in opposite directions so that the rotation of one is reversed bv any suitable gearing. In a modification the driving shaft 0 does not slide, but the roller shafts A, A<1> are moved in opposite directions about their outer ends so as to bring each roller into contact with a different disc, the rollers being then driven in the same direction.

Abstract: 1,221,640. Segment addressing system. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 May, 1969 [11 May, 1968], No. 23573/69. Heading G4A. Segment addressing system wherein an address has a first portion indicating a particular segment and a second portion indicating a location in the segment has at least two registers into which the base address determined by the first portion can be entered to obtain an actual address from the base address and the second portion. A logical address LA contains a Segment Number SN and an Address in the Segment AS. SN is passed via register SNR to a comparison device D where it is compared with a value 0 and the numbers in registers SNE and SNT. If SN is not equal to any of the numbers signals SKN<SP>1</SP>, SKE<SP>1</SP>, SKT<SP>1</SP> open gate D 3  to cause the word SW held at the location defined by SN to be read from store M into one of registers SW 2 , SW 3 . SW 1  holds the base address corresponding to SN= 0. A selector D 4  determines which register is used and determines whether the number from SNR is entered into SNE or SNT. Preferably a new number is entered into a register that has held its contents longer. The base address in SW 1 , SW 2  or SW 3  is added to address AS from register ASR in adder X to produce a physical address FA. The words SW contain a base address SB and a segment length SL the latter being compared in LV with a portion of AS to determine whether the address required lies in the defined segment. The words SW can also include accessibility bits. The system can also be used for program addressing, the words SW holding the initial address and the length of a program.

Abstract: 406,320. Cutting tobacco. DEARSLEY, G., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Aug. 23, 1932, No. 23587. [Class 5 (i).] A tobacco-cutting machine of the type having means for automatically grinding a rotatable cutting blade or blades during the rotation thereof by means of a grinding element movable relatively to the knife edge or edges, comprises means for controlling the direction of the initial movement of the particles resulting from the grinding operations so that such particles move away from the tobacco and /or means for deflecting the said particles away from the tobacco. A machine similar to that described in Specification 365,997 comprises a carrier 3 provided with knife blades 4, rotating about an axis 5. A grinder 6 of annular form rotates about an axis 17 inclined to the cutter axis 5, such inclination causing the particles to have an initial movement away from the tobacco. Shields 7, 8 mounted between the front of the machine and the carrier 3 catch the particles produced by the grinding operation, a suction device communicating with the interior of the shields for removal of the particles therefrom ; such shields may, however, be used with a non- inclined grinder. The knife carrier 3 is recessed on its inner face so as to clear the shields but comprises projections coacting with projections on the shields to jolt the latter. Instead of fixed shields, a shield may be provided for each knife and mounted on the knife carrier, the particles being ejected from such shield by centrifugal force or being removed by suction or mechanical means. Instead of employing an inclined grinder, a grinder of large diameter may be used. The knives are arranged and fed forwardly and a diamond 16 automatically reciprocated as described in Specification 365,997 : a shield may be provided between the diamond and grinder and the tobacco, means being provided to remove the particles therefrom.

Abstract: 920,592. Making bows or rosettes. THAYER Inc. June 30, 1961 [July 1, 1960], No. 23655/61. Class 141. A machine for making a bow or rosette from a length of ribbon comprises a rotatable mount on which the bow is formed, an intermittent feed device for feeding ribbon in loops to the mount, means for retaining the loops on the mount, and means for operating the feed device and cooperatively rotating the mount. The machine comprises a carrier 36 which carries at equally spaced positions four rotatable spindles 41, the carrier being intermittently rotatable through an angle of 90 degrees so as to bring each spindle 41 in turn to four successive stations where the various operations are carried out. The loops of the bow are formed on the spindle 41 located at position I at the left-hand side of Fig. 2. To form each loop, a reciprocating shuttle 85 through which the ribbon is fed is moved towards the spindle head 41 on which the previously formed loops are clamped by means of a coaxial presser spindle 78; during the forward movement of the shuttle the spindles 78, 41 together rotate through a predetermined angle to form a loop of ribbon, Fig. 23; a hand member 50b mounted on an adjacent arm of the carrier 36 is rotated and lowered so as to clamp the ribbon against the spindle head as the spindles stop rotating; the presser spindle 78 is then raised and the feeding shuttle 85 completes its approach, oscillating transversely so as to feed the ribbon around the fingers of the hand 50b between the ribbon already clamped and the raised presser foot 83; the presser spindle is again lowered into its clamping position, the hand member is moved away and the feeding shuttle reciprocates to feed another length of ribbon. After formation of the required number of loops, a cutting mechanism 100 is rotated to the position shown in dotted lines and is actuated to sever the bow from the rest of the ribbon. The carrier is rotated through 90 degrees and a second bow is then formed at position I while a stapling apparatus (not shown) at position II is actuated to drive a staple through the first bow which is still held on the spindle head by the hand member 50b. After rotation of the carrier through a further 90 degrees, the arms 106 of a bow-discharge mechanism at position III engage the first bow and remove it from the machine. Specifications 920,593 and 920,594 are referred to.
