Abstract: 1398937 Vehicle detector GEC - ELLIOTT TRAFFIC AUTOMATION Ltd 6 May 1974 [4 May 1973] 21310/73 HeadingGlN [Also in Division G4] In a vehicle detector system utilizing the fall in inductance as the vehicle passes over a loop L, pulse generating means produces a number of pulses in a marked period dependent on loop inductance and means for determining that number at intervals and affording a representation of vehicle presence in dependence on a comparison of that number at different times. In the embodiment loop L is longer than a normal motor, and may extend over every lane is no discrimination between lanes is required. Oscillator 3 generates a sinusoidal signal of frequency dependent on loop inductance and a selector 5 counts the oscillation cycles to produce a marked period (say 100 oscillation periods) followed by an interval (say 50 oscillation periods). A counter 8 counts pulses from a clock 6 in the marked period and is reset before each count, the count being lower when a vehicle is present. Low counts are stored in store 1 and high counts in store 2, and a store 9 controls traffic signals. A logic chart for determining current count transfer is described, Fig. 2 (not shown).

Title: Thermally controlled fan apparatus
IPC: F01P7/06
Filed: 1963-05-30
Abstract: 994,754. Axial-flow fans; cooling fans. STANDARD THOMSON CORPORATION. May 30, 1963, No. 21589/63. Headings FIB and F1C. [Also in Division G1 A fan comprises a number of blades carried by a support structure, and a separate thermally responsive means connected to each blade to rotate the blade with respect to the support structure and thereby vary the blade pitch. A cooling fan for an I.C. engine comprises a hub 60 in the form of a pair of discs 64, 66 secured together by bolts 72 and attached to a shaft 62 by bolts 63. Pairs of semi-cylindrical bulges 68, 70 in the discs 64, 66 form cylindrical housings for the spindles 74 of the blades 80, bearings 75 being provided. An enlarged end 76 of each spindle 74 engages thrust bearings 78 within enlargements 77 of the bulges 68, 70. When the temperature of the air rises above a predetermined value, a thermally responsive material 81 expands and moves a piston 82 inwardly from the position shown in Fig. 9, the movement being transmitted by a compression spring 99 to a plunger 86 without appreciable compression of the spring. The engagement of cam slots 97 in the end portion 92 of the plunger 86 with pins 98 carried by the hub 60 causes the plunger to turn as it moves inwards. The rotation of the plunger 86 is transmitted to the spindle 74 through the engagement of a square-section part 90 of the plunger with a square bore in the spindle, whereby the spindle is turned to increase the pitch of the blade 80. After the plunger 86 has reached the limit of its inward movement as shown in Fig. 12, any further inward movement of the piston 82 merely compresses the spring 99. When the fan speed increases above a certain amount, centrifugal force moves the plunger 86 outwardly, compressing the spring 99. The resultant rotation of the plunger 86 and the spindle 74 decreases the blade pitch. A sealing means may be provided between the material 81 and the piston 82. In a modification,' the piston 82 and its spindle 84, together with the spring 99, are omitted, and the plunger 86 is acted on directly by the thermally responsive material 81. Resilient means may be provided to urge each plunger radially outwardly.

Title: Simultaneous read-write addressing
IPC: G06F13/16
Filed: 1963-05-30
Abstract: 978, 649. Digital computers. SPERRY RAND CORPORATION. May 30, 1963 [June 13. 1962], No. 21669/63. Heading G4A. A data-storage system comprises a destructive readout memory having two address registers, the second address register controlling restoring or writing in of data while simultaneously the first address register can receive a new address. The arrangement described comprises a 3-dimensional magnetic core or thin film memory 10 having N planes of X rows and Y columns, a first address register 16 (G register), a second address register 24 (H register) and a data input/output register 50 (Z register; only one stage shown). The timing of the memory input and output operations is under the control of a tapped delay line 62 which receives an inserted pulse at the commencement of the operation. In a READ operation cycle the desired address is placed in the G register 16 and a signal applied to a line 64 initiates the operation. The address in the G register is translated at 18 and drivers 12 cause the addressed data word to be read out to the Z register 50. The address in the G register is now transferred via an enabled AND gate 28 to the H register 24. During the subsequent part of the READ cycle, the H register is effective to control the restoration of the read out data from the Z-register 50 via and AND gate 56 to the address from which it was read out; and concurrently with the restoration, the G register is cleared and can receive a new address on line 14. A WRITE operation is generally similar to a READ operation and provides similar overlapping.

Title: Door closer
IPC: F16F9/16
Filed: 1965-05-24
Abstract: 1,103,857. Door closers. P. ZAHN. 24 May, 1965 [25 May, 1964], No. 21815/65. Heading E2M. A fluid-check door closer comprises a housing 11 insertable in a door and having its interior divided into two fluid spaces 35, 20 by a valve body 18, one space 20 being formed by the interior of a hose 19 affixed to valve body 18, valve 18 permitting rapid flow of fluid in one direction but throttled flow in the other direction between the two spaces, and a piston 15 being provided for moving fluid through the valve. As shown, the valve body 18 and hose 19 are formed in piston 15 which runs in housing 11. An end member 12 of the piston is connected via linkage to the door frame to load a spring 28 as the door is opened, fluid flowing from hose 19 into space 35 via bore 22 and past a flexible valve ring 26. As the door closes under the action of spring 28, it is checked by fluid throttling through a groove 27 between ring 26 and body 18, and through a one-way ball valve 23 into hose 19, bore 22 being blocked by ring 26 forced against body 18. When the door is almost closed, it encounters a further damping force provided by ring 26 meeting a damping member 32 and loading spring 34 as member 32 slides along pin 31. Pin 31 is longitudinally adjustable to ensure that when the door is closed, ring 26 is forced against member 32 and member 32 is forced against flange 31a of pin 31. The door is then subjected to a locking force because it must be moved against a vacuum in chamber 35 until ring 26 is freed from member 32 for bore 22 to be opened. In a further embodiment (Fig. 5, not shown), the valve body and hose are stationary in housing 11, and the varying length in the housing of a spring loaded plunger causes fluid flow through the valve. Also, the bore 22 and the ball-valve in bore 21 are dispensed with, the throttle action being provided by groove 27. Ring 26 may be biased toward bores 21, 22 by fixing it in the concaved face of body 18 (Figs. 8, 9, not shown).
