Title: Rail clip locating device and concrete foundation therefor
Inventor: ROOKE JOHN DENIS NORIE
IPC: E01B9/18
Filed: 1989-03-09
Abstract: A concrete foundation for a railway rail, the foundation having secured to it first and second clip-anchoring devices 4 and 5 each capable of receiving and anchoring one leg of a rail-fastening clip, and having incorporated in it between said devices a locating means 20 for locating a third clip-anchoring device, which is a hook-in anchoring device, in a first position when desired and in a second position when desired, the arrangement being such that the foot of a rail may be between the first clip-anchoring device and the third clip-anchoring device when the latter is in its first position and the rail may be held down by clips driven into these two clip-anchoring devices and, when it is desired to change the gauge of the railway track, the clips may be withdrawn, the third clip-anchoring device may be withdrawn from the locating means and installed in its second position, the rail may be moved to a new position laterally displaced from the first position, and the clips may be driven in the second and third anchoring devices to hold the rail down in its new position. A locating device 20 for a hook-in clip-anchoring device 45 may be incorporated in a concrete foundation 1 for a railway rail 50 by being inserted in a mould before wet cement mix is poured into it to form the foundation. From a flat and horizontal upper surface 40 of the device 20 extend two vertical passages 25 and 26 which lead to horizontal passages 27 and 28 into either of which a horizontal limb 47 of the device 45 can be inserted via the passage 25 or 26. Insertion and removal of the device 45 requires rotation of the device 45; it cannot be removed purely by upward movement. <IMAGE>

Title: Adjusting the posture of a foot
Inventor: HYVAERINEN TUOMO
IPC: A43D1/02
Filed: 1992-04-09
Abstract: A method and device for the selection of an insole and/or of a shoe that adjusts the posture of the foot and for determination of the biomechanical mode of operation of the foot. In the method, the foot is placed on a measurement base (10), on the symmetry axis (18) of the measurement base, and the load applied by the measurement base to a rigid support base in relation to the symmetry axis (18) of the measurement base (10) is measured. For the measurement, the supported symmetry axis of the foot to be measured is aligned with the symmetry axis (18) of the measurement base (10) by guiding the position of the foot onto said symmetry axis by the heel and by the toes. The measurement of the load is carried out preferably in two stages so that first the load is measured when the person stands on the measurement bases with straight legs, and then the load is measured when the knees have been bent substantially 45 DEG  from the straight posture. <IMAGE>

Title: Vibratory conveyor.
Inventor: MADDOCKS KEITH LEVER
IPC: B65G27/34
Filed: 1992-06-04
Abstract: A distribution system 10 comprising a vibratory conveyor includes a number of conveyor modules 32, 34, 36 to distribute bulk food products to user locations 38, 40, 42 at which are located packaging machines 14. The product is fed using longitudinal vibration of a product carrying tray 44 supported by leaf springs 45 which resist lateral vibration relative to a base 70. At the downstream end only of the conveyor, additional lateral vibration is induced by vibrating the base 70 on which the leaf springs 45 are mounted. First and second electromagnetic drive means 80, 84 for the longitudinal and lateral vibrations are controlled by a clock pulse generator (82 Figure 5) to operate in synchronism either in phase or in anti-phase and are controlled independently of each other as to operation and amplitude. The arrangement enables optimised distribution of fines in the bulk food product. <IMAGE>

Patent GB-2271203-A (GB)
Title: Digital processing system
Inventor: HARPER JOHN ANTHONY
IPC: G06F15/167
Filed: 1992-10-01
Abstract: Two processors 10 and 20 are coupled together. The primary processor 10 initiates operations to be performed. For each operation, it constructs a command which it sends through a buffer 30 for the second 20 to carry out; the first then completes the task of the operation, using information generated by the second. Commands are queued at 40 in the second, which assigns each a sequence number at 42. A sequence number register 13 in processor 10 contains the sequence number of the command whose final task it is completing. It then signals 20 (by a bit in the next command), which sends via 44, 45, and a location 32 in a status register 31 the sequence number of the next command which it has performed. A counter 47 stores the number of performed but unacknowledged commands. The sequence numbers are cyclic to base 2, ie. alternately 0's and 1's. <IMAGE>

Title: Electrical connector with hinged contact holder
Inventor: ENDO TAKAYOSHI
IPC: H01R13/42
Filed: 1992-10-19
Abstract: A connector consists of a housing (A) with terminal accommodating chambers (1) formed therein and a rear holder (B) integrally joined to the housing by hinge straps (2). The housing (A) has openings (1a) extending to the terminal accommodating chambers, and the rear holder includes terminal locking projections (12) insertable into the terminal accommodating chambers (1) through the openings (1a). The rear holder (B) is fittable on the housing in two steps of a preliminary engaged state and a fully engaged state. In the preliminary engaged state (fig. 4), the terminal locking projections (12) are located out of movement paths of terminal lugs in the terminal accommodating chambers and, in the fully engaged state (fig. 6), the terminal locking projections (12) are located in the movement paths to prevent the terminal lugs from slipping off from the rear of the terminal accommodating chambers. In a further embodiment (not shown) the hinged holder can slide on the body, and is formed in two parts attached by a further hinge. The hinged part prevents movement of the terminals. <IMAGE>

Title: Wheel clamps
Inventor: YAMABE HIDEYASU
IPC: B60R25/09
Filed: 1994-02-04
Abstract: The vehicle detention device provides a pair of stopper blocks 1, 2, where one of the stopper blocks 2 is movable relative to the other stopper block 1 secured to a guide shaft 4. A locking means 5, 6, is provided to prevent the movable stopper block 2 from shifting in the direction away from an objective tire 3a in which both the stationary and movable stopper blocks 1, 2 remain in contact with the tire 3a at both sides of the ground contact point of an objective wheel 3. Using a pair of chains 25, 26, the objective wheel 3 is fastened and placed under detention in which the stopper blocks 1, 2 are closely held in contact with the tire. Since mechanical components available for releasing the fastened condition are fully concealed by means of a key-provided cover unit, no one can readily remove the vehicle detention device from the restrained vehicle without operating a proper key, thus securely holding the objective vehicle under the state of detention. <IMAGE>
