Title: Controlling an electromechanical stepping mechanism
IPC: G06K15/22
Filed: 1965-10-19
Abstract: 1,130,142. Recording - apparatus. CALIFORNIA COMPUTER PRODUCTS Inc. Oct.19, 1965 [Oct. 26, 1964], No.44287/65. Heading G1J. A reversible electro-mechanical stepping mechanism is controlled in response to digital data which, in the case of, say, the x-axis motor 12 (or y-axis motor 13) of an x-y plotter 10, comprises a time sequence of commands-in register 25 - each of which is normally passed by decoder 26 to logic circuit 17 to specify a forward +x, reverse -x or nil increment of movement of a drum (or carriage) on the x-axis (or y-axis). The motor control apparatus also includes means responsive to a special command inserted into the data when the motor 12 (13) is required to step continuously in one direction for a certain interval of time and responsive to a further special command terminating the interval to cause the sequence of commands in each such interval to be treated as specifying a positive, negative or nil increment of velocity of the motor. To this end, the control apparatus includes means 40, 42, 43 for averaging and integrating the increment commands to provide command signals to the motor 12 (13) to step the drum (carriage) at a rate which can substantially exceed the rate of supply of digital data commands. This mode of operation is termed "slewing" and produces faster plotting over intervals where the motors are not required to reverse.

The apertures in the mask are equally spaced and the area of the aperture 12 for the central zone is such that the light from the central partial image is equal to that from either of the lateral partial images. In the case where there are more than three filter zones, the aperture of the objective is such as to cover all the zones completely except the two lateral zones which are only partially covered. An aperture of f/2À5 is specified.

The centrifugal separators, 11, are held against the pipes, 10, by the clamps, 13. Steam is generated in the core 3 within the moderator tank, 2 and flows through the passages, 9, in the lid, 8, to the separators. The steam is forced to the longitudinal axis of the riser pipe, 14, by the oblique blades, 18, which rotate the steam-water mixture. The separated water is forced through the perforated conical part, 15 and falls in the gap between 14 and the bell-shaped casing 23. Vibration of the arrangement is prevented by the grids 25, 26, 27. A further water separation is effected by the domed deflection caps, 28. The clamp, 13, comprises a rod, 35, which is screwed at its lower end into the pipes, 10, or 41.

In the tube illustrated an optical input is applied to a photocathode 18 and a grid 32 is disposed adjacent the surface 30 to collect any secondary emission. In operation the surface 28 is maintained at + 500 volts to shield the storage surface 30 from the field from the screen 16, which is at 8 KV, during the steps of erasure, priming and writing. For reading a flooding beam is produced from the photo-cathode, and the potential of surface 28 is increased to 800 volts. The storage surface 30 may be charged either positively or negatively according to the potentials applied to the photocathode, the grid 32, and the conductive layer 26 (Fig. 5, not shown). In the tube shown both the input and the output are optical, but neither need be.

The apex of the triangular cross section of the vent channel 7 extends close to the upper surface of said flange. The nipple 1 passes through an opening in the retainer cap 4 which is screwed onto the outer wall of the neck 5 of the bottle 6, the shape of the screw threads allowing air to flow past them and into the vent channel 7 on the creation of a low pressure in the bottle. On tightening the retainer cap 4 on to the upper rim of the neck 5, the elastic flange 2 is compressed and clamped between cap 4 and neck 5. The dimensions of the vent channel 7 are sufficient to prevent liquid from flowing out of the bottle through said channel, but allow air to enter said channel when a low pressure is produced in the bottle.

Hydraulic cylinders effect pressure control of the wheels 15,16 of a mulling machine of the kind comprising of flat-bottomed open-topped cylindrical crib 10, a mulling assembly including a cross head 21 carrying mulling wheels and plough blades 17, 18, and means for turning the assembly about a vertical axis. A horizontal shaft 29 is rotatably mounted on the cross head 21 with a trailing link 31 coupled to the shaft and pivotable therewith, and an axle (not shown) for the mulling wheel 16 is carried by the trailing link, with a double-acting piston-cylinder unit 35 mounted on the cross head with the piston movable in a horizontal direction and coupled to the shaft via a link 33. For the wheel 15 a similar arrangement comprising a rock-shaft 38 carrying a link 40 for the axle 41 of the wheel 15 is operated by a piston/cylinder unit 44, which acts in opposite sense to the unit 35. A control device comprising a pressure gauge 55 an adjustable valve 56 and an adjustable restrictor 54 changes the degree and direction of application of pressure fluid to the cylinder, so that the latter rotates the shaft 29, 38 to a controlled extent in one or other direction, and thus applies the wheels 15,16 downwards at a selected pressure, or raises them. Compressed air is applied to the cylinders via a distributor 49 which rotates with the mulling assembly.

A synthetic resin tube having a helical reinforcement material embedded in its wall is formed by winding wire 10 under tension about a rotating spindle 4, releasing the tension and then applying a synthetic resin band 13a over the helically coiled wire and heat sealing the abutting edges of the band. The reinforcement wire 10 is located in grooves 5 in driven rollers R 1 , R 2  located on opposite sides of the rotating spindle 4 and oppositely inclined thereto so that the wire 10 is wound under stress in the form of a helical coil on to the spindle 4. The pitch of the helical coil is determined by the inclination of the axes of the rollers R 1 , R 2  to the spindle 4. When the coil leaves the rollers R 1 , R 2 , the winding stress is removed and the band 13a of thermoplastic material is wound over the coil, the abutting edges of adjoining turns of the band being heat sealed to one another thereby forming a continuous inner covering layer. A further reinforcement material 14 such as thread or wire is wound on the inner covering layer which in turn is covered by a further covering layer of thermoplastic material 13b. The tube thus constituted is fed to a conveying section comprising grooved rollers 20 arranged with their axes inclined to the axis of the spindle 4 and driven in the opposite direction but at the same circumferential speed as the spindle. The angle of the axes of the rollers with respect to, and their distance from, the spindle 4 can be individually adjusted. Oscillation of the tube T about the spindle 4 is prevented by guide rollers 38a, 38b, 38c, Fig. 7, maintained in contact with the outer surface of the tube T and a roller 37 rotatably supported on an arm 36 attached to the end face of the spindle 4 and engaging the inside surface of the tube T.
