Patent GB-588704-A (GB)
Title: Improvements relating to electrically actuated remote-control apparatus
IPC: G05D3/14
Filed: 1945-03-05
Abstract: 588,704. Electric control systems. ROTAX, Ltd., and ARNOT, A. R. E. March 5, 1945, Nos. 5478 and 22759. [Class 40 (i)] [Also in Group XXXVII] In a system in which a receiving potentiometer is driven into correspondence with a sending potentiometer, each potentiometer comprises a main and a subsidiary part which control respectively two polarized relays by which one or other of two motor-controlling contactors is energized. The relays or the contactors also control braking, or other retarding means which comes into action when correspondence is nearly achieved. The retarding means may be an interrupter in the motor circuit. Fig. 1 shows master and followup potentiometers each comprising a main resistance u connected across the supply and having a contact v mounted on spindle w, and a short subsidiary resistance x in parallel and having two sets of alternately arranged contacts mounted on slip rings 2, 3. If the potentiometers are far from a position of correspondence a heavy current flows between the contacts v through winding g of a first relay causing it to operate. Relay windings q or r or both of a second. relay are also energized due to the current lowing between slip rings 2 and 3. Current is applied from one of the contacts p of the first relay to one of contactor wiridings d, depending on the direction of flow of current in winding q, causing its armature e to be pulled up and close contacts f, g and f<1> g<1>. Closure of contacts f, g energizes the motor a through one of its field windings m, and closure of contacts f<1> g<1> energizes a brake release winding k. The motor then drives the potentiometer until it nears a position of correspondence when the current flowing between contacts v is insufficient to energize the first relay and it drops out. Current is then supplied from the contacts p of the second relay through resistances to the windings d so that the armature drops back a little and opens contacts f<1>, g<1> The brake is then applied to the motor causing it to run at a lower speed until a positional correspondence is obtained. In a modification, Fig. 2, a vibratory. interrupter 5, 6 is placed in the motor circuit for retarding the speed of the motor. When both relays are energized, coil 9 of an electromagnet is short-circuited so that closed contacts 7, 8 short circuit the interrupter 5 and current flows continuously to the motor. When the first relay drops out, coil 9 is energized to open contacts 7, 8 and put the interrupter into circuit. The interrupter may be placed in other parts of the motor circuit, e.g. across part of the field winding or across the armature winding. Specification 588,703, [Group XXXVI], is referred to.

Title: Improvements in or relating to instructional and/or practice devices for ball games
IPC: A63B69/36
Filed: 1961-02-15
Abstract: 935,959. Practising appliances. M. V. BLAKE. Feb. 2, 1962 [Feb. 15, 1961], No. 5650/61. Class 132 (2). A device for practising swinging a golf club, bat, or the like, comprises a member attached to a handle and containing a pivoted weight which is restricted to move only when the centrifugal force developed in swinging the device has reached a predetermined value. As particularly described, the invention is applied to a golf club, the housing for the weight simulating the head of the club, and comprises a weight 20 pivoted to the housing at 19, and a latching member 21 pivoted to the housing at 22 and urged towards its weight-latching position by a spring 33 bearing against a member 36 bolted to the housing. In its latched position, a roller 40 on the weight 20 engages a groove 28 in the latching member, the latching member being pivoted by centrifugal force to release the roller as the club is swung. Once the roller is released, the weight 20 moves under the action of gravity to assume the position illustrated in Fig. 7, the roller 40 then preventing forward movement of the latch under the action of spring 33. The device is reset by flicking the club in the opposite direction, thereby freeing the members 20 and 21, allowing member 21 to move towards its weight-latching position and causing the roller 40 to ride back over the surface 30 towards the groove 28. When freed, the weight swings about its pivot to hit against a plate 12 simulating the striking face of the club, and simultaneously the distance of its centre of gravity from the handle of the device increases, thereby providing a retarding effect such as would be experienced upon striking a ball. The force required to free the weight may be varied by adjusting the screw 25 of the latching member, this altering the position of the centre of gravity of the latter relative to its pivot 22. Also, as the device is swung, a thread 50 anchored to the housing takes up a positive determined by the resultant air stream, thus indicating the direction of swing. The thread passes under a clamp 53 which is automatically moved to clamp the thread in position as the weight 20 is released from its latched position.

Title: Improvements in means for attaching metal skins of aircraft components to their supporting structures
IPC: B64C3/26
Filed: 1945-03-15
Abstract: 589,161. Aircraft structures. HAWKER AIRCRAFT, Ltd., BETTERIDGE, P. D., and ROWE, E. T. March 15, 1945, No. 6600. [Class 4] In order to impart a smooth surface, free from irregularities, to the skin of aircraft components, a predetermined tension is imparted to the skin prior to its application to the supporting structure and maintained during the application of the skin. The skin may be stressed by springs, or by heating same, securing its edges to a rigid frame while expanded and then allowing it to cool. Heating may be effected by electric pads, steam, or heated liquid. In the case of components such as ailerons, elevators, or flaps, which are of narrow chord in proportion to their length stress may be applied in the direction of their length only. Fig. 1 shows a jig for the assembly of such a long, narrow, component comprising rib-locating members 18 at the base and spring tensioners 22 passing through side members 12 and connected to rigid clamps 24, secured to the narrow ends of the plate 20. The tensioning members are capable of adjustment to enable the stress applied to the skin to be varied. For stressing larger sheets, holes may be drilled along its edges for the insertion of the ends of springs carried by a jig frame extending around the edges of the sheet (Fig. 7, not shown). Figs. 3 and 6 show an arrangement suitable for the assembly of a fin or rudder, the base 42 of the jig having an opening 44, conforming to the spar contour, and a vertical plate 46 having an opening 48, conforming to the profile of the component. The sides of the jig are formed by inclinedmembers 52. The component is assembled by inserting the ribs 59 and associated structure, laying the skin sheets 66 on opposite sides of the jig, heating the sheets, for example, by electric pads 62, drilling holes at the edges of.the sheets corresponding to holes 56 along the edges of the jig for the reception of securing bolts, allowing the .sheets to cool to induce the desired stress, and then securing them in position by rivets passing through the sheets and internal structural members. An alternative method of inducing stress .in the skin consists in securing its edges to a rigid frame, the latter of which is heated and thereby expanded, (Fig. 8, not shown).
