Title: Improvements in conveyor mechanism
IPC: C21D1/63
Filed: 1943-07-03
Abstract: 569,882. Metal - heating furnaces. INCANDESCENT HEAT CO., Ltd., and GROVES, H. July 3, 1943; No. 10820. [Class 51 (ii)] [Also in Groups II and XXX] A flexible conveyer especially for heattreatment apparatus has spaced carriers f and is associated with an inclined track h for part of its run on which the carriers automatically bunch together with. the flexible conveyer looped between the carriers, a stationary period being thus permitted to each carrier. The conveyer comprises a pair of endless chains a driven by a sprocket b and connected by spaced rods e with rollers e at each end adapted to run - on a horizontal track j and in the inclined track h. Freely suspended from the rods e are the cradles or baskets f which receive the articles to be treated as the cradles pass downwardly in front of the outlet from a furnace c. The conveyer then passes into a quenching bath d and the rollers e<1> enter the inclining track h within the bath, the weight of the cradle being thus transferred to the track and the rollers running freely down the track so that the cradles are bunched together with the chains looped between them and remain stationary for a predetermined period until the slack is taken up. The cradles are unloaded at g. The invention may be applied to pickling, drying, cleaning or washing operations. The conveyer may be intermittently driven.

Title: Improvements in and relating to electromagnetic recording and reproducing arrangements for acoustic vibrations
IPC: G11B5/004
Filed: 1929-04-09
Abstract: 319,681. Stille, C. Sept. 26, 1928, [Convention, date]. Magnetic machines and records.-Sound is recorded magnetically on a steel tube or bar of small diameter relatively to its length, the tube or bar being rotated whilst the recording or reproducing head is traversed along it. Preferably, two such bars or tubes are provided in one machine, the recorder or reproducer being adapted to be shifted over, after traversing the whole length of one bar, so as to continue operating by acting on the other bar. In the recording apparatus shown, a microphone M is connected through an amplifier V to the recording magnet A. This is mounted on one end of a carrier arm which slides along a guide bar b, the other end of the arm engaging one or other of two feed screws p<1>, p<2>. Steel bars 1, 2 are rotated as the magnet A is traversed along them in turn, the carrier arm being swung over, by means not shown, when the end of the bar 1 is reached, so that the second feed screw operates to move the recording magnet in the reverse direction along the bar 2. The starting and stopping means for operating the bars 1, 2 may be controlled by the magnet-traversing means. Instead of two screws, a, single reversible screw may be provided; or, instead of rocking the magnet, means may be provided for successively pushing two or more steel bars or tubes under the recorder. This may be done, for example, by means of a rotary magazine containing the bars. Fig. 3 shows part of a reproducing-machine, and illustrates the means for mounting the steel bars 1, 2, in either the recording or reproducing aparatus. Each bar has a pointed end, which acts as a bearing centre, the other unpointed end having a groove in which a rib on a driving shaft engages. When one bar has been utilized, it may be removed and replaced by another whilst the second one is in operation. Both bars may be driven continuously, instead of each being started and stopped at the beginning and end of its operation. Specification 541/03 is referred to.

Patent GB-124529-A (GB)
Title: Improvements in or relating to Gyro-compasses.
Inventor: PERRY JOHN
IPC: G01C19/38
Filed: 1916-08-03
Abstract: 124,529. Perry, J., aud Brown, S. G. Aug. 3, 1916. Gyroscopic compasses.-The pendulous or gravitational factor controlling the gyroscope acts through a relay or intermediate source of power. The gyrowheel and associated parts may therefore be mounted in almost neutral equilibrium. In the constructions illustrated in this abridgement, an air blast derived from the air in the gyrocasing is used to effect the displacement of a controlling- weight along a lever arm. Figs. 3 and 4 show, in plan and side elevation respectively, a form in which liquid is transferred from one vessel H to another vessel H by the differential pressure of an air blast controlled by a pendulum F carrying floats f<1> dipping into vessels G carried by the gyrocasing A, on which the vessels H are also carried. The pendulum F carries at its lower end a plate f in front of the air nozzle E, Fig. 5, for distributing the blast between the parts of an air chamber K which are so connected to the vessels H that any inequality in the distribution of the blast causes a difference of pressure in the vessels to effect a transfer of liquid. An auxiliary pair of liquid-containing vessels J, acting in a similar manner but oppositely to, and out of phase with, the vessels H, is provided in order to damp oscillations. Other pendulum devices also adapted to be unaffected by short period movements may be employed, e.g. a pendulum with an auxiliary gyroscope for increasing the period of oscillation, or a pendulum with viscous-fluid damping-means. This latter is illustrated in Figs. 9 and 10, which also show a form in which the righting-torque is produced directly by the differential action of two air nozzles E<1>. The air nozzle E<1> on either side is provided with an air-director f<7> carried on a pendulum F<2>, which is pivoted in brackets m<2> on the gyro-casing A and carries a blade dipping into very viscous fluid contained in a vessel M<1> mounted on the casing A. Relative movements of the pendulums and casing produce displacements of the directors over the nozzles E<1>, and consequently a difference between the air discharges, so that a righting-torque about the horizontal axle of the casing A is produced. In another construction, an air-hlast is caused to act with a differential cooling effect on two electrically heated wires, which are carried on a pendulum device, and by means of which a torque-producing motor is controlled.
