Patent GB-1259191-A (GB)
IPC: B65G23/00
Filed: 1969-01-28
Abstract: 1,259,191. Inductive signalling. NATIONAL RESEARCH DEVELOPMENT CORP. 27 Nov., 1969 [28 Jan., 1969], No. 4763/69. Heading H4U. A conveyer, for transferring articles to and from a vertical storage rack with horizontal and/or vertical conductors marking storage positions in the rack and carrying phase signals as control information, comprises a control arrangement receiving phase information from a pick-up coil and comparing it with a phase reference representing a desired storage position and controlling a motor on the conveyer. In one embodiment a pair of parallel vertical wires is provided at each vertical row of storage bins and at the desired row the left-hand wire carries a signal of phase # 1 , and the right a signal of phase # 2 , all pairs to the left of the desired row receiving # 1 , and all pairs to the right # 2 . The reference phase is set at (# 1 +# 2 )/2 and a phase discriminator and servo amplifier cause the motor to move the conveyer until the pick-up coil receives this phase of signal, when it is positioned mid-way between the desired wire pair. A second phase discriminator is provided with a latching circuit to store the detected phase and pass it to the first discriminator to maintain its output between vertical rows. Movement to the desired horizontal row is obtained by a different arrangement where, as shown, a programmer 28 supplies a different phase signal to each wire 17 (corresponding to a horizontal row), and to line 18 a signal corresponding to the desired row. Phase changer 26 controlled by the position of the platform 30 produces an output to discriminator 23 approximately corresponding to the row reached, and this is compared with the signal picked up from line 18 by coil 25 to cause motor 34 to position the platform roughly at the right level. Accurate positioning is then controlled by the output of phase discriminator 20, the input to which from coil 25 is advanced by 45 degrees so that zero output occurs when coils 16, 16a are positioned equidistant from the directed row wire 17. Since independent control systems are provided for horizontal and vertical movement both systems can operate together to move the conveyer diagonally to a desired location. Different horizontal shelving systems in different vertical racks can be accommodated by arranging for the output of programmer 28 to depend on the horizontal position of the conveyer. The invention is described as also suitable for a car-parking system.

The apparatus may comprise two water softeners in parallel so that one may always be in use. In Fig. 2 the metering device comprises a vane wheel 21 driven by softened water passing along conduit 8 which is associated with two softeners (not shown). In use after a given number of revolutions or angle of revolution of vane wheel 21 causes an impulse to be delivered from electrical transformer 25 to pump 27 which is operated to deliver additive from container 19, and to counter 31. After a given number of pulses counter 31 delivers a pulse to a switch (not shown) which causes one softener to be cut off from the water flow and to be regenerated by salt, and the other softener to receive the water flow. In other embodiments the additive container may have level sensing means to control the switching over of the softeners, and the rotation of the wheel may be measured mechanically.

Abstract: 1305432 Semi-conductor devices STANDARD TELEPHONES & CABLES Ltd 9 Dec 1971 [11 Dec 1970] 58936/70 Heading H1K Avalanche breakdown initiated at a rectifying junction, such as that between N type GaAs region 5 and P type Ga x Al 1-x As region 6, spreads throughout the region 5 but is prevented from extending any further by the presence of N type region 4 formed of a material having a larger energy gap than that of the region 5, e.g. Ga x Al 1-x As. This is particularly advantageous in transit-time-limited devices. The doping level in the region 5 should preferably be slightly less than that in the regions 4 and 6, and preferred doping levels and thicknesses are specified for two values of reverse breakdown voltage. In the device shown contact layers 2 and 8 sandwich a structure which includes, in addition to the regions 4, 5 and 6, an N<SP>+</SP> type GaAs region 3 and a P<SP>+</SP> type GaAs region 7. Either one of the regions 6 or 7 may be omitted. The structure is mounted either way up on a heat sink 1. In a modification the regions 6 and 7 and the contact 8 are all replaced by a Schottky contact, which provides the avalanche-initiating rectifying junction on the region 5.

This avoids pressurization of the kiln due to the incoming cold air having a greater density than the outgoing warm air. Heated air is passed between vertically-spaced courses of timber 12 from the fan 30 either firstly through the centre section to the space 28 and then back through the side sections, or vice-versa. Air heaters 26 may comprise lengths or coils of steam pipes, or may be electrical. Steam is admitted through manifold 50 to provide humidification. Fan and damper control circuit (Fig. 3).-The direction of rotation of the fan motor is determined by a timer switch 54, e.g. with contact between L and F, and no signal from controller 74, the damper motors are in closed positions. A signal from controller 74 then energizes the relays 74, 70, and motor 56 is operated to a partially open position set by resistance potentiometer 68 (and then stops) whilst motor 58 opens fully.

In a self-levelling hydro-pneumatic damper when a piston-rod 4 with a piston 17 moves downwardly below the normal load position shown a pump piston 33 moves into an aperture 34 in the piston 17 and pumps fluid from a supply space 23, past a valve 24 in the base of a working cylinder, into the chamber 5 within the pistonrod from which it is forced, past a valve 14, into the operating space 30 of the working cylinder an aperture 25 in the base of the working cylinder, through which fluid flows from the operating space 30 to the supply space 23 on regulation, being closed by a valve 27 during this upward pumping action. The stem 31 of the valve 27 is pressed downward by a spring 12 which is stressed by a sleeve 11 which also surrounds the head 13 of the valve stem, a buffer 3 on the upper end of the sleeve 11 engaging the piston-rod 4 when the piston 17 projects below the desired level. A spring 29, which also presses against the valve 27, closes the latter to prevent drainage of fluid from the operating space 30, e.g. when the wheels are unsupported with the vehicle jacked-up, and the spring 12 is no longer effective. The stroke of the rod 4, after effecting downward movement A, is limited by a plate 37 and a buffer 7 forming a double seal, the upward movement B being limited by a surface 35 on the rod 4 abutting an end plate 36. The volume of fluid displaced by the piston-rod 4 acts upon a gas cushion 22 in an annular space between the working cylinder and a cylinder 19 the open side of the elastically-deformable container 21 for the gas cushion being closed by a seal ring 16. Oil seeping past a rod seal 10 flows through an annular groove 9 and a duct 8 to the supply space 23.
