Title: Reaction time measuring device - has timer releasing weighted needle halted by brake actuated by pedal etc.
IPC: A61B5/16
Filed: 1968-06-28
Granted: 1974-10-31
Abstract: The device measures the physiological reaction time to a visual or acoustic stimulus by the movement of a weighted body, pivoting on an axis not passing through its centre of gravity. A needle (5) moving over a calibrated dial (6), is coupled directly to the spindle (2) of a pivoting body (1). A system of levers, coupled to a timer, holds needle, spindle and body stationary for a time, and then releases them when a bell rings or a lamp lights. The body and needle can then be halted by a braking system actuated by a pedal (38) or button, or from a remote point by switch (40) and solenoid (39). The dial is calibrated by simultaneous high-speed cine-photography of the needle movement and of a stop-watch calibrated in 100ths of a second. The time between resetting and operation of bell or lamp is adjusted by an eccentric acting against the timer resetting lever and thus rewinding it for a variable amount.

Title: Improvements in or relating to means for preventing ice particles from being formed in or carried by the air into the air intakes of aircraft and other fast-moving vehicles
IPC: F02C7/047
Filed: 1947-01-13
Abstract: 620,249. Air inlets for aero engines. NAPIER & SON, Ltd., D., and SAMMONS, H. Jan. 13, 1947, No. 1057. [Class 4] [Also in Group XXVI] A guard is provided in front of the air inlet of a propulsion plant and hot air or gas is directed into the inlet. The guard G5, Fig. 5, carried by the spinner A is impervious and all the air passes through the annular opening J3 between the edge of the guard and the annular air-inlet F1 around the boss of an airscrew B. The guard G2, Fig. 3, is pervious to allow the air to pass directly through it. When the guard is blocked by ice formation, the air passes through the annular opening J1 beyond the guard. Hot air from the compressor, or, hot exhaust gas is directed into the air stream through ports K, Fig. 5, in the outer rotating wall H of the air inlet through ports K1, Fig. 3, in an annular wall N fixed to the screen G2 and the spinner A and through ports L in the airscrew spinner A. The hot gas reaches the hollow wall N by pipes N1. The hot gas is injected into the interior of the spinner and wall H through nozzles M1, M2, in a ring main M. The supply of hot gas may be controlled thermostatically. The annular opening J1, Fig. 3, is provided with flap valves O. In the position shown they close the opening J1. In the dotted line position the opening J1 is open and the flow through the screen is stopped. The impervious guard G5, Fig. 5, is mounted on guides Q and can be moved axially by means of a screw P1 and motor P2 to vary the annular opening J3. The pervious screen may be used without the annular wall N and may be concave towards the airscrew boss. The impervious screen may be fixed axially and the flap valves omitted. The screens may be applied to the full bore inlet to a jet-propulsion plant. Specification 578,769 is referred to.

Filed: 1916-01-24
Abstract: 100,583. Burdahl, C. Jan. 24, 1916. Infantry shields.-A circular shield 5 is adapted to be rolled along the ground and is provided with an auxiliary guard 34 for the feet of the soldier and with standards 51 for supporting the shield in a stationary position. The shield comprises a circular metal plate 5 rigidly secured to a rod 9 and having a rearwardly projecting flange 7. One soldier supports the shield by grasping a sleeve 17 mounted to revolve on the rod 9, whilst a second soldier rolls it along by means of a ring 23 secured to the shield by spacing bolts 24. The guard 34 is supported by a hanger 26 so that it can be moved vertically relatively to the shield; the hanger carries a grooved roller 28 working on the inner edge of the ring 23, and a bracket 30 projecting up behind the outer edge of the ring. A toothed sector 38 is mounted on a bolt 37 secured to the guard 34, and a second toothed sector 42 is attached to the hanger 26; lateral projections 41, Fig. 27, on the sector 38 work in slots 44, 47, Figs. 21 and 19, in the sector 42 and hanger 26 respectively, and a lever 32, pivoted in a bracket 31 on the hanger 26, projects through slots 45, 50 in the sectors 42, 38 respectively, so that by turning the lever the guard may be raised or lowered relatively to the shield. By turning a second lever 49, which is pivoted to the bolt 37 and secured to the guard by a bolt 48 working in a slot 39 in the sector 38, the guard can be tilted to prevent jamming or to facilitate the movement of the shield up an incline. The standards 51 for supporting the shield in a stationary position comprise angle-bars provided with pointed foot-plates 52 and metal blocks 53 having projecting studs 54; the metal blocks 53 are passed through apertures 55 in the shield so that the lugs are disposed on opposite sides of the shield. When not in use, the standards 51 are removably secured to parallel plates 60, Fig. 16, spaced from the shield by bolts 58; the standaids, which are provided with apertures to receive the extremities of the bolts 58, are laid across the plates 60, one on each side of central bolts 68, and hasps 65 are then pressed down on to the bolts 58, the heads 67 of the bolts 68 passing through slots 66 in the hasps; to secure the parts, the heads 67 are turned at right-angles to the slots 66. Loop-holes 72 in the shield are provided with closure plates 74 wording in channelled guides 73 and adapted to be secured in position by spring-controlled pins engaging notches 78 in the guides.

Abstract: 1,149,430. Coke ovens. KOPPERS CO. Inc. 10 Jan., 1967 [18 Jan., 1966], No. 1396/67. Heading F4B. In a regeneratively heated coke oven battery of the Becker type in which crossover flues 26 connect sets of heating flues 20 through headers 24, each heating flue 20 has a lean gas port 58, a rich gas port 56 and an air port 60 in its floor (46), Fig. 1 (not shown) and a lean gas port 54 and rich gas port 52 in the top wall 50 of a laterally extending protuberance. Control of the various supply ducts and connections is such that the lean gas ports are used for air when firing with rich gas, and excess air is supplied through port 60 only when firing with lean gas. A rich gas main 74 running longitudinally below the regenerators 28, 30 supplies the high ports 52 through branches 78 and underjet ducts 92, 94 and supplies low ports 56 through branches 80 and underjet ducts 86.
