Title: Improvements in helicopter aircraft
IPC: B64C27/82
Filed: 1944-07-07
Abstract: 600,013. Helicopters. DEHN, F. B. (Bell Aircraft Corporation). July 7, 1944, No. 13024. [Class 4] In a helicopter rotor incorporating a stabilizing inertia member, cyclical pitch variations are imparted to the rotor blades by a pilot-operated control member which reacts against the inertia member. In the form shown in Fig. 3, the rotor hub 34 is mounted for universal tilting movement on the driving shaft 30, the upper end of which carries the inertia member comprising a rod 32 with enlarged ends. A link 39 carried by the rotor hub is connected by vertical links 36, 42, to the rod 32 and the outer race 43 of a saturn ring, respectively. In the event of the shaft 30 being displaced from the vertical, the member 32 tends to maintain its horizontal plane of rotation and, acting through the links 36, 39, feathers the rotor blades to restore the shaft to the vertical. The pilot may impart cyclical feathering movements to the rotor blades by tilting the saturn ring 43, 44, by a control member 35, the link 39 pivoting about the point 38 as fulcrum. In the embodiment according to Fig. 5, a flywheel 55 driven by a shaft 57 passing through the main rotor shaft 30 engages a disc 59 connected by links 60 to a lower saturn ring 62, through the race of which pass pilot-operated control screws 70, 75, connected to an upper saturn ring 64, the outer race of which is attached to a vertical link 66 connected to the rotor hub 69. According to a further modification, Fig. 6 (not shown), the inertia member is placed below the lifting rotor and is connected to the pilot-operated control member by cables passing over pulleys mounted on the rotor hub. Figs. 7 and 8 show a construction in which the pitch of the rotor blades may,be varied simultaneously by equal amounts by means of a pilot-operated bell-crank 154 connected to a tiltable member 145 which actuates a verticallyslidable sleeve 138, connected to the inertia member 133 which operates the pitch control arms 124 of the rotor blades through links 131, 128, 129, 126. Cyclical pitch variations are imparted to the blades by a gimbal 168 actuated through control arms 175. Specification 580,231 is referred to.

Title: Improvements in the means for holding and positioning sensitised paper or card when enlarging
IPC: G03B27/58
Filed: 1928-05-03
Abstract: 316,913. Pearson & Co., Ltd., E. T., and Lowen, C. G. May 3, 1928. Enlarging.-A holder for the sensitized paper or card comprises two hingedly-connected interfitting frames. The outer frame 1 has inner dimensions to fit the card used, the inner walls being preferably inclined to the plane of the frame. The inner frame 2 fits into the outer frame and, when it rests on the card, masks the outer edge. The inner frame is raised automatically, for example by means of a spring 4, when a finger-catch 7 releases the tongue 8. A stop 13 limits the rise of the inner frame, and may also turn to one side to allow this frame to swing right over. To enable the cards to be easily removed from the frame, a finger 9 having a lip 10 fitting underneath the card is pivotally mounted on the outer frame. The finger 9 may be spring actuated, causing the card to rise automatically with the rise of the inner frame. Means for affixing the frame 1 to the baseboard of the enlarger in any required position are described. The device may be connected to the lighting circuit of the enlarger in such a way as to switch on the exposure lamp when the inner frame is pressed down, and switch off when it is raised.

Abstract: 1,040,839. Indicators for switches. TECH DEL Ltd. March 22, 1965 [March 26, 1964], No. 13047/64. Heading H2B. [Also in Division G1] Indicating-apparatus comprises a pointer 2 fitted to a knob 1 so that one grips the other and the resilience of an annular disc-like portion 7 of the pointer 2 serves to restrain relative rotational movement between the knob 1 and the pointer 2, which has an indicating portion 10 projecting beyond the circular periphery of the disc 7. The knob 1 and the pointer 2 are each moulded in one piece from a synthetic plastic material in which the strain produced in the material if it is stressed up to half the ultimate tensile stress, disappears when the material is relieved of the applied stress. By applying a sufficient relative force between the pointer and knob they can be relatively rotated to set the pointer to the zero point of a scale when the knob has turned a D-sectioned shaft 3, e.g. of a potentiometer to an initial position. In modifications the portion 10 is omitted and either (a) the diameter of the face 9 of the pointer disc 7 is greater than that of the face 5 of the knob and the outer projecting part of the face bears graduations on a single line, or (q) the faces 9, 5 have the same diameter but a part of the knob 1 is cut away to expose graduations on a line inscribed on the outer part of the face 9. To assist the shoulder 8 of the pointer 2 to enter the cylindrical recess 6 of the knob 1, the outer edge 12 is chamfered. The free end of the shoulder 8 may be formed with a circumferential rib to engage a corresponding recess in the surface 6. The knob may be mounted on the shaft of a rotary switch.

[Class 38 (ii).] In vacuum - dis. charge apparatus such as mercury arc rectifiers in which risk of back ignition due tc excess voltage on the anodes 2 is reduced by the association with each main anode of a protective anode 3, the main and protective anodes being fed respectively through in-ductance 4 and resistance 7, continuous ionization of the discharge paths of the protective anodes is ensured by arranging a continuously burning normally directed arc to impinge thereon. This effect may be produced by causing each of a pair of protective anodes to ionize the discharge path of the other, or by associating with the protective anodes an auxiliary electrode 8 or a group of such electrodes fed by a source 9 or from a potential divider in parallel with the load 6. Alternatively, the exciter anodes of the rectifier may be used for causing ionization of the discharge paths of the protective anodes. Specification 388,808 is referred to.

Abstract: 1,180,184. Catheter placement device. BRUNSWICK CORP. 19 March, 1968 [24 May, 1967], No. 13322/68. Heading A5R. A catheter placement device comprises a cannula 12, a stylet or needle 10 seated in said cannula with its piercing point extending forwardly of the cannula 12, a catheter 16 for inserting through said cannula when the needle is removed therefrom and a ferrule 18 slidably carried on the catheter 16 for locking the catheter relative to the cannula. As shown, a flexible plastics cannula 12 has a tapered distal end portion 34 and a flared proximal end portion 38. A polyvinyl ferrule 18 has a tapered body portion 54 extending from a wide-mouthed proximal end 56 to a narrowmouthed distal end 58, the size of which approximates to the diameter 45 of the catheter 16. To lock the device, the ferrule 18 is moved along the catheter until the distal end portion 58 wedges between the inner slope 40 of the cannula (Fig. 6) and the outer surface 45 of the catheter 16. To release the lock, the ferrule is twisted and moved towards the proximal end of the catheter, whereupon the catheter can be moved in or out relative to the cannula.
