Title: Improvements in or relating to apparatus for obtaining a displacement proportional to a variable rate of movement
IPC: G06G3/08
Filed: 1945-03-26
Abstract: 594,793. Gun fire control devices. STEVENS, A. H. (Sperry Gyroscope Co., Inc.). March 26, 1945, No. 7586. [Class 92 (ii)] Relates to a smoothing, differentiating and predicting circuit particularly adapted for use in gun fire control systems, and consists in an arrangement of variable speed devices whereby the displacement of the control member 16 of a predicting variable speed device 17 is proportional to the rate of displacement xo of an input shaft 1 giving, for instance, a target's position xo. In the construction shown, present target position xo is supplied to the apparatus by shaft 1 which leads to a differential 2 whose output displaces the ball carriage 4 of a variable speed device 5, the disc 9 of which is driven by a constant speed motor 7. Carriage 4 drives a cylinder 8 on a shaft 10 leading to a differential 11 whose output shaft 12 displaces a ball carriage 16 of a variable speed device 17 whose disc 18 is driven at a speed 1/tp, where tp represents the time of flight of a projectile. Carriage 16 drives cylinder 21 on a shaft 20 which leads, as shown, to both of the differentials 2, 11 which serve to produce on the output shafts 3, 12 the differences between the rotations of their respective input shafts. In operation, if shafts 1 and 19 rotate at constant speeds and the apparatus is in equilibrium, then shafts 1, 10 and 20 will rotate at the same speed xo, and it can be shown that shaft 12 provides the required measure of prediction xotp which is added by differential to xo data supplied by shaft 1. The result xo+xotp appearing in shaft 31 gives the target's future position. The apparatus ensures that a smooth measure of prediction is supplied by shaft 12 when spurious perturbations appear in shaft 1. Further, a true measure of prediction is given by shaft 12 when the time of flight is changing at a constant rate. In such a case, the shaft 20 still rotates at the same speed as shaft 1, and the ball carriage 4 remains in a position in which shaft 10 differs in speed by shaft 20 just sufficiently to produce the required motion of ball carriage 16. Specifications 494,172 and 494,288 are referred to.

Title: Improvements in or relating to ventilating systems
Inventor: GILBERT DANIEL
IPC: F24F11/75
Filed: 1961-03-02
Abstract: 936,164. Ventilating. CARRIER ENGINEERING CO. Ltd. Jan. 30, 1962 [March 2, 1961], No. 7725/61. Class 137. In a ventilating system comprising a plurality of enclosures arranged in groups, and an air-conditioning unit individual to each group, each unit being arranged to deliver a constant volume of air and having its input connected with sources of air to be conditioned, the delivery of air to each unit from one source is selectively controlled through a common control device in accordance with the requirements of the individual groups. The invention is applied to a ship and is aimed at reducing the load on the air-conditioning plant at times when cabins and other enclosures are likely to be unoccupied. As shown, a group of enclosures 1, 2, 3 receive air through reheaters 4 from a conditioning unit 5 which includes means for controlling both the humidity and temperature of the air supplied at a constant rate by a fan 9. Fresh air and return air are supplied to the unit from sources 7, 8, respectively and the delivery of the fresh air is controlled by a damper 10. The position of this damper is controlled by an electric timer which actuates valve 12 to allow compressed air from a source 13 to pass to damper-operating pneumatic motor 11. The timer similarly actuates valves 12a, 12b at predetermined times to control the air supply to other groups of enclosures. In a modification, the motor 11 operates a damper in a recirculating duct which returns a proportion of air from the output directly to the input of the conditioning unit. Other modifications are referred to, e.g. the timer 14 may be replaced by a manual control device.

Title: Improvements in means for securing airscrew spinners, aircraft cowlings and other like parts
IPC: B64C11/14
Filed: 1945-04-03
Abstract: 589,767. Fastenings. DE HAVILLAND AIRCRAFT CO., Ltd., and DOVE, E. B. April 3, 1945, No. 8222. [Class 44] In means for securing two separable parts, particularly airscrew fairings and aircraft cowlings, comprising a bolt or stud 20, Fig. 1, and a spring-pressed latch 10 engaging the stud, with manually operated means movable to actuate the latch and lock it in the engaged position, a trip member 52 is housed in the latch and spring-pressed outwardly to a latch detaining position, but is prevented from assuming that position until the latch has moved to the disengaged position, whereupon, when the parts are separated, the act of bringing the parts together causes the trip member to be pushed in to free the latch and allow it to engage the bolt. The trip member 52 has an outer part of reduced diameter, and a part 64 of intermediate diameter, which work in a slot in the body member 12 having narrower and wider parts 56, 62, Fig. 3. When the parts are assembled, the nose of the member 52 bears on a flange 60 of the stud 20, and the trip member is pressed inwardly. When the latch is retracted to face the stud, the end 54 of the trip member rides off the edge of the flange 60, and the member moves outwardly. As the parts are separated, the latch moves forwardly to a slight extent until the part 64 of the trip member comes up to the narrower part of the slot in the body 12. The latch is thus held retracted, so that the stud can be inserted easily on reassembly, when the trip member is pushed inwardly by the flange 60, allowing the reduced part 54 to move in the narrower part of the slot, and the latch 10 to engage the stud. The means for manually moving and positively locking the latch comprise a member 30, Figs. 4 and 5, which can rotate and slide in a bore in the body 12, and which has a flanged head 28 engaged in a notch in the latch 10. The member 30 is normally retained in the locking position shown in Fig. 4 by a pin 38 engaging in a part-annular groove therein, but on rotation, by means of a screwdriver inserted in a slot 34, to the position in which the pin 38 is in line with a key-way 40, can be pushed down, carrying the latch with it. A ball catch 46 yieldingly holds the member 30 in the locking and unlocking positions. Specification 570,278 is referred to.
