Title: Improvements in and relating to stereotaxical methods and apparatus
Inventor: DOBBELEER GILBERT DESIRE PHILO
IPC: A61B19/00
Filed: 1959-04-01
Abstract: 868,657. Stereotaxical apparatus. UNIVERSITE DE LOUVAIN. April 1, 1959, No. 11075/59. Class 81 (2). A stereotaxic apparatus has a device, for holding the head, which is movable about three perpendicular axes. The patient is placed on a chair with the upper part of his head through the central space in a main frame 1, Fig. 1, which is pivoted, at the back of the chair, on an axis 2 which may be raised and lowered vertically. Adjustable holding-arms 7, 8 mounted on pillars 37, 38 are mounted in an arcuate slide adjustable by a screw 17 so as to be movable about a vertical axis 18 and this slide is itself mounted on another arcuate slide 19, controllable by a screw 25 so as to move around a horizontal axis 22. After the head has been positioned by means of the above adjustments it may be finally held by further adjustable rods 23, 24. A scale 26 is then placed in position and an X-ray photograph is taken on a plate 55, so that the vertical and horizontal position of the desired site may be determined. The scale 26 is then removed and a pivoted frame 41, Fig. 2, is placed on the sides of the frame 1. It is set in the desired fore-and-aft position, by scales 39, 40 and its side members are adjusted so that the pivotal axis 42 is at the height of the site. A second X-ray photograph is taken on a plate 60 to determine the position of the site in this plane and this is used in the adjustment of a horizontal slide 46 by means of which an arcuate slide 48 can be arranged to align an adjustable probe 52 with the site. The centre 53 of the arc then coincides with the site and the probe will reach it from whatever point on the arc 48 it may be directed.

Title: Improvements in torque transmission mechanism
IPC: F16H33/08
Filed: 1933-04-18
Abstract: 404,184. Linkwork. ROGER, G., 23, Victoria Road, Macclesfield, Cheshire. April 18, 1933, No. 11230. [Class 80 (iii).] In a torque-transmission mechanism of the type in which centrifugal force is used, a number of radial arms 9 carrying weights 12 are mounted on an axis 8 eccentric to a driven shaft 2, one only of said arms being described. The axis 8 is on an eccentric disc 6 fast on the shaft 2. The arm 9 or weighted part thereof is connected by pivoted links to a driving disc 1, the edge of which may be formed flat to take a belt, and which is loose on the shaft 2. The weight 12 is connected by a series of pivoted links 21-25 to a pin 26 passing through the disc 1 and carrying on the other side of the disc a weight 27. A lever 28 is pivoted to the link 23 at 23a and to the disc 1 at 29. It also carries a bowl 30 bearing on the edge of the disc 6. A bowl on a pin 31 on the disc 1 is adapted to bear against the weight 27 and thus take the thrust due to centrifugal force, which is thus neutralized. When the arm 9 reaches, by counter-clockwise rotation, the position shown in Fig. 2, the weight 12 tends to produce a reverse rotation in the shaft 2. This is prevented by the weight 27 which is turned slightly about the pin 26 by the disc 6 bearing against the bowl 30 and moving the links 21-25. The centrifugal force of the weight 27 is transferred to the arm 9 and overcomes the clockwise torque due to the weight 12. The eccentricity of the disc 6 may be varied ; for example, by passing the shaft 2 through a slot in the disc and through a bearing capable of being fixed to the disc in a plurality of positions. Specification 394,619 is referred to. The weight 12 and lever 28 are shown detached in Figs. 7 and 6 respectively.

Title: Improvements in or relating to tape transport systems
IPC: G11B15/58
Filed: 1964-03-20
Abstract: 1,033,791. Automatic speed and tension control. AMPEX CORPORATION. March 20, 1964 [April 17, 1963], No. 11869/64. Heading G3R. Magnetic tape 11 co-operates with head assembly 21 and is associated with reels 35, 37 as well as a pair of counter-rotating capstans 40, 41. Depending on which actuator 43 or 44 is engaged, the tape is urged into driving contact with one of the capstans. A data processing system provides start and stop signals through circuit 50 to control the operation of the actuators. The transport system further comprises double-ended vacuum chambers 51a-51d having vacuum ports 52a-52d. Rollers 53, 54 are coupled to tachometer generators 55, 56 and sensing holes 60a-61b are associated with pressure-sensitive switches 62a-63b. Servo control arrangements 70, 71 for the reels receive velocity-representative signals from the tachometer generators as a basic means for regulating the loop-lengths. Other signals are derived from actuators 46, 47 and the pressure-sensitive switches so as to bias the loop-lengths towards the optimum positions for reversing from a given operating mode. Thus, when the loop is above hole 61a for forward movement in the chamber 51c-51d the signal from sensor 62a is subtracted from the other signals whereby take-up motor 79 is driven more slowly than the rate of tape-feed into the chamber. When the hole 61a is passed by the loop, however, the signal from sensor 62a is added to the other signals, thereby increasing the speed of motor 79 so as to withdraw tape from the chamber at a greater rate than it is being fed in. The tape thus oscillates about the hole 61a during this mode of operation. When the tape is being withdrawn from the left-hand chamber, the optimum position is at the short-loop location, to protect against sudden reversal at high speed. Additional sensing holes may be placed between the holes 61a, 61b so that the tape is positioned between these intermediate holes when the transport system is at standstill. This safeguards against the possibility of the tape being stopped in the short-loop position, and then being started in the same direction to withdraw tape from the chamber.
