Title: Control apparatus for controlling the movement of a member
IPC: G05B19/23
Filed: 1973-12-31
Abstract: 1457520 Automatic control HYPER-LOOP Inc 31 Dec 1973 [2 Jan 1973] 60258/73 Heading G3N The movement of a member from a first to a second position in response to a train of pulses is effected at a manually selected rate of change whereby the pulse repetition rate is decreased substantially to zero when the member reaches the second position. As shown, clockpulses from a generator 20 are fed to a ramp control 21, set by a manual device 22, producing a variable frequency pulse train to a counter 24. The clockpulses are also fed to a control 25, set by a manual device 26, deriving a pulse train the output frequency of which is proportional to the velocity of a moving web being fed to a punch press, not shown. The output of the control 25 is fed to a repetitive adder 28 where it is multiplied by the contents of the counter 24 to produce a pulse train on a line 29 which, through logic 30, controls the in-feed velocity of the web through a drive 32. The pulses on line 29 are also fed to a main counter 33, initially set to the desired web feed distance signals on a line 35 and to an up-counter 34 initially set to zero by logic 30. During a press-feed operation, the ramp counter 24 fills and is then isolated from control 21 by  logic 30 so that the web velocity is at a maximum. When the contents of up-counter 34 equals the value in counter 33, as indicated by a comparator 39, the counter 24 is re-connected to control 21 and decremented to provide a progressive speed reduction. When the contents of counter 33 reaches zero the web has travelled the set distance and the drive 32 stopped by logic 30. The out-feed drive 43 is controlled by logic 30 through a logic unit 44 which increases the pulse rate to drive 43 and stretches the web in the vicinity of the press. The number of operating cycles is controlled by a counter 46.

Abstract: 612,148. Printing-surfaces. HEINRICH, Inc., H. H. May 10, 1946, No. 14164. Convention date, Dec. 15, 1945. [Class 100(ii)] [Also in Group XX] In a machine for registering the printing- surfaces 6 of a key cylinder 1 with the surfaces of one or more cylinders 12, the cylinders 1, 12 are mounted in bearings 7, 8, 17, 18 in a frame, and the cylinders are geared to a common gear 19 so that they can be rotated in unison, and a spring pin 37<1> normally holds the gears stationary. To register the printing-surfaces 21 of cylinder 12 with corresponding surfaces 6 of the cylinder 1, mirrors 33-37 are arranged to reflect images of the plates 6, 21 so as to be visible in superposed form through a window aperture 25, and any lack of register is corrected by adjusting the printing-surface 21 until exact register is attained. This operation is repeated until all the surfaces 21 are registed accurately, and these surfaces are fixed in registered position. If more than one set of printing-surfaces is to be registered, the casing 23 in which the mirrors are mounted can be adjusted in a direction parallel to the axis of the cylinders 1, 12. To effect this the supports 28, 29, 30, 31 of the casing 23 can slide along guides 26, 27, and a scale 38 and pointer 39 permit of exact adjustment. To permit of access to the cylinders 1, 12 the casing 23 can be turned counterclockwise about the pivotal support 26 of the casing, and a rest 32 holds it in inactive position. The mirror 37 can be angularly adjusted and locked in adjusted position by a screw-and-nut. The mirror 36 may be provided with crossed-hair lines, and electric lamps 43, 44, may illumine the printing-surfaces.

Abstract: 682,711. Cables;cable sleeves; carrying conductors through partitions; mounting terminals. BRITISH THOMSON-HOUSTON CO., Ltd. May 16, 1950 [May 24, 1949], No. 12203/50. Classes 36 and 38 (i). A sheathed cable is made by reducing the cross-sectional area of an insulating body, which is of a material which, after being deformed while cold, returns to its original shape on heating, drilling a hole through the body, inserting a conductor in the hole, placing the body within a sheath and heating to cause the body to expand and tightly engage the conductor and the sheath. Polymerized tetrafluoroethylene, polymerized monochlorotrifluoroethylene and polymerized methyl methacrylate are examples of suitable insulating materials. To make a termination or connection for a fluid-filled cable, a swaged insulating body 4, in which a conductor 5 has been inserted, is positioned within a steel shell 10. On heating the insulation expands against the walls of shell 10, filling the annular space 11, and against conductor 5. Such an assembly may also be used to seal the conductor 5 through the wall of a container. Specification 652,054 is referred to.

Filed: 1978-07-29
Abstract: In order to retain securely in set positions a part (e.g. a net frame or rod-rest cradle) which is angularly adjustable relative to a support (e.g. a stick or handle) the part or the support is provided with a bar having inclined planar surfaces meeting at one or more ridges, a connector on the other one of the part or support having a passage through which the bar passes rotatably, and a locking member on the connector which clamps against the bar to restrain it from rotation in set positions.

Title: Conveyor vibrating with adjustable frequency and amplitude
IPC: B65G27/12
Filed: 1978-08-22
Abstract: A known transport device for cargo has a transport plate 2 mounted on springs 3 which is displaced periodically against the action of the springs so as to throw the cargo along the transport plate. The invention provides such a transport device in which the displacement of the transport plate is adjustable and in which the frequency of the displacement is also adjustable. In this way it is possible to ensure that the thrown cargo lands on the plate at exactly the time the plate reaches its rest position for different types of cargo. The adjustments are made by adjusting the vibrator 4 which may be a hydraulic motor or may be pneumatic, electric or mechanical. Additionally, the rigidity and initial setting of the springs can also be adjusted. <IMAGE>

Title: MFM data encoder with write precompensation
IPC: G11B5/09
Filed: 1979-03-02
Abstract: An encoding circuit for converting an input stream of serial data bits at (12) to an MFM encoded output stream of serial data bits with write precompensation comprises a ROM (4) acting as a look-up table and providing an MFM coding for a current bit at QB the coding depending upon the previous two bits at QC, Q1, as well as the next, at Qa, the encoded signal being provided in serial format 22. With write precompensation, a transition which would be expected at either of the positions "NORMAL" Fig. 2 is shifted to +/-250 nS in dependence on the ROM algorithm. The precompensation corrects for bit shifting which otherwise occurs when MFM data is recorded on the inner tracks of a magnetic disc recorder. The presence or absence of precompensation is controlled by a signal at A4. Use of delay lines for precompensation is thus avoided. <IMAGE>

Title: Endpoint drift measurement and correction for automatic titrations
IPC: G01N27/44
Filed: 1979-05-29
Abstract: In a coulometric titration system, titrant is produced until the end point is reached and the charge and time measured. The system is allowed to stabilise for 5-10 seconds and then, during a monitoring period (30-60 seconds), drift, if present, is detected by generation of titrant to restore the system to its end point. If draft is detected, a third period, starting and ending with titrant generation is determined and, from the amount of titrant added and the duration of the third period, the drift rate is determined. The drift rate is used to correct the titration value. The method may be used for the coulometric titration of water by the Karl Fischer reaction. <IMAGE>
