Title: Suture loading apparatus
Inventor: WHITE GEORGE W
IPC: A61B17/04
Filed: 2009-06-25
Abstract: A suture loading device 90 for mounting on a bone anchor insertion device (10, figure 1) has suture retaining means 94 which pivot to expose or cover an aperture 98 in the loading device in which is disposed a suture snare. The body of the device defines a passage leading away from the aperture through which the snare can pass. As it does so, the snare is compressed, causing it to grip the suture. The loading device may have two retaining members covering two apertures housing two snares so that it is suitable for use with two independent lengths of suture. Also disclosed is a closed loop snare (100, figure 12A) having teeth at one end to grip the suture when the snare is compressed. The teeth may project in the plane of the loop (as in figure 12A) or perpendicular to it (as in figure 14).

Title: Roller ski with steerable truck
Inventor: DUDGEON TIMOTHY
IPC: A63C5/06
Filed: 2009-12-09
Abstract: A roller ski comprises a binding attached to the upper surface of the ski with two or more trucks 22,23 mounted to the underside of the ski, one or more of which trucks are steerable. The invention has the advantage in that the skis can be steered by the application of a force to an edge of the ski, thereby simulating skiing on a hard surface such as a road or skate park. Downward pressure on the edge of the roller ski generates a sideways moment around boss (56, figure 5) causing steering bar (54) to turn sideways so enabling turning of the roller ski. The degree of turning and suspension aspects of the truck can be adjusted.

Filed: 1960-03-23
Abstract: 897,416. Cam mechanisms. SULZER FRERES S.A. March 23, 1960 [March 24, 1959], No. 10327/60. Class 80 (3). [Also in Groups XIII, XXVI and XL (a)] A valve 130 controlling injection of water into a steam pipe 121 is operated by cam 127. The rate of flow of steam is measured by an orifice and a differential pressure gauge 123 which rotates the cam. The steam temperature is measured by a beam 124 provided with a pivoted knife-edge, which detects thermal expansion or contraction of the pipe, and which through a mechanical linkage moves the cam axially. The angular and axial position of the cam and hence the valve setting thus depend on steam flow and steam temperature.

Title: Improvements in or relating to devices for synchronising a rotating system
IPC: H04N5/04
Filed: 1961-03-22
Abstract: 981, 754. Automatic speed control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 22,1961 [March 25, 1960], No. 10444/61. Heading G3R. For phase control, positive control pulses from a rotating member and negative reference pulses are separately applied to terminals 1, 2, associated with the input of a multivibrator 5 having its square wave output voltage applied to the grid of triode 14. A square wave voltage having the same polarity as the input pulse is developed at the cathode of the triode 14. When a positive pulse appears, capacitor 22 is charged through rectifier 21, a negative pulse causing the capacitor to discharge through resistor 23. In this manner, a sawtooth voltage is developed across capacitor 22 which is connected to capacitor 25 through rectifier 24, the capacitor 25 being connected to a positive supply terminal through resistor 19. The average voltage across the capacitor 25 is a measure of the phase difference between the two pulse series and forms a control voltage for maintaining synchronizm. If the positive pulses tend to lag the negative pulses, the voltage across capacitor 25 decreases so that more current is passed through coil 32 which is in circuit with double triode 26. The rotating member is driven by a motor through a magnetic coupling whose energizing coil 32 increases the speed of the member when the excitation of the coil is increased. When the control pulses lead in phase, the reverse effect occurs. Upon starting the rotating member, a capacitor 11 in circuit with the multivibrator 5 is charged to such a voltage that the positive pulses applied to terminal 1 do not become effective, and the output of the multivibrator is such that the member is driven with maximum torque and its speed rapidly approaches the desired value. The control voltage across the capacitor 25 becomes operative only when synchronizm is reached and the phase control becomes effective. During starting, the voltage across the capacitor 25 is always so low that the current through the coupling coil 32 is at a maximum.

Abstract: 110,768. Fritsch, G. A. Aug. 2, 1916. Clock-work actuation; switches, quick-make.- In a clock-controlled switch mechanism for use in electric lighting and heating installations, two gaps 52<1>, 53 in the circuit are closed and opened respectively at predetermined times by plungers 48, 49 carried by casings 42, 43 rotated by spiral springs 59 enclosed therein. The clock dial 11 is fixed upon the front of the box 10, but the two dials 12, 13 rotate with wheels 22, 23 which are driven from the wheel 20 of the clock mechanism in such a manner that the hour-hand wheel 21 and the two wheels 22, 23 rotate at the same rate and in the same direction. Fingers 26, 27 are carried by spindles 24, 25 which are fitted with arms 32, 33 carrying pawls 30, 31 engaging with ratchet-wheels 28, 29 upon the wheels 22, 23. The springs 59 tend to turn both casings 42, 43 in an anti-clockwise direction, and when the apparatus is set, pawls 36, 37 prevent rotation of the casings. To set the apparatus, the finger 26 is turned over its dial 12 to the time at which it is desired the circuit shall be closed, and the finger 27 is correspondingly moved to the time at which the circuit is to be opened again; by the aid of finger grips 44a, 45<a> the casings are turned to the position shown in Fig. 1 so that the plungers 48, 49 are up and down respectively and the gap 52' is open and the gap 53 closed. When the clock indicates the time shown by the finger 26, arm 32 trips the pawl 36 so that the casing 42 is turned by its spring to close the gap 52' and complete the circuit, and the lamps &c. remain lighted until the arm 33 trips the pawl 37 to allow the casing 43 to be turned by its spring to break the circuit at 53. A hand-operated switch 58 permits of the installation being used in the interval between the time of setting the apparatus and that at which it comes into operation. According to the Provisional Specification, there are other contacts between the plungers and the upper contacts of the gaps 52<1>, 53.
