Title: Improvements in or relating to means for boring cylinders
IPC: B23Q9/00
Filed: 1940-09-30
Abstract: 542,787. Reboring engine cylinders. BROOKSIDE ENGINEERS, Ltd., and MIDDLETON R. J. Sept. 30, 1940, No. 14718. [Class 83 (iii)] The base of a device for re-boring internal combustion cylinders in situ is provided with magnetic means for holding it to the cylinder block. An electric motor e mounted on the base drives a splined shaft f connected through gears i, k, m, n, in a slidable casing to a gear j on the boring bar d which is carried in a quill guided in a guide portion b. The feed screw h is splined in the gear n and works in a nut r driven at a speed slightly higher than that of the screw through gears o, p, to impart slow downward feed to the casing and boring bar. A clutch operated by tappet mechanism may be used to disconnect the gear m from its spindle while a brake is applied to the feed screw to obtain the quick-return movement of the boring bar. The motor e and the electromagnet coils u are connected in parallel and the circuits are completed by the contacts shown in Fig. 4 arranged so that the motor cannot be started by movement of the sliding contact spindle 18 until the spindle 17 has first been moved to complete the circuit of the electromagnets. In a modification, Fig. 5, the circuits are completed by a switch arm 21 which first bridges the contacts 11, 12 to energize the electromagnets and then bridges contacts 14, 15 to start the motor. In some cases permanent magnets which may be neutralized by pole-piece movement inter-related with the motor switch may be used instead of electromagnets. The magnetic field produced by the magnets attracts some of the cuttings to the base a and lessens the risk of damage to the engine bearings &c.

Abstract: 846,295. Centrifugal casting-machines. TRINDLER, F. May 9, 1957 [May 19, 1956], No. 14738/57. Class 83 (1). A centrifugal casting mould for rings is divided into separable halves in a plane perpendicular to the axis of rotation, said halves being rotated separately and displaceable relatively to one another during the casting, before separating said halves for removal of the cast ring. The mould halves G are mounted in housings 3, 3a on supports 1, 1a respectively, each driven by an electric motor 10 and belt 12, and braked by a band 13 operated by a cylinder 14. The housing 3, with support 1 and the mould half thereon, is displaceable on guide rods 4 rigid with the housing 3a, by pistons 7, Fig. 3, in cylinders 8. The assembly is mounted on pivots 21 so that the axis of rotation of the mould may be inclined at any position between the horizontal and the vertical. Cooling air &c. may be drawn in or blown into parts 17 &c. In a modification, the support for one mould half is mounted so that the distance between the mould parts may be varied radially as well as axially. In operation, after an initial solidification, the mould parts are moved apart slightly in order to separate the contracting casting, at least at one point, from the mould wall. Favourable crystallization may then be produced by the application of coolant through the gap between the mould parts.

Title: Improved apparatus for treating air to be used for food preservation, causing precipitation of atmospheric humidity, therapeutic and other purposes
IPC: A23L3/3409
Filed: 1930-05-17
Abstract: <PICT:0355261/III/1> <PICT:0355261/III/2> Apparatus for treating air for use in preserving food, in causing precipitation of atmospheric moisture, and for therapeutic and other purposes, comprises an electrically and magnetically insulated compartment 4 supported on insulated columns 9 and having an insulated tube 3 maintained at a positive potential, e.g. by means of a valve rectifier 11, air being conducted through tube 3 into compartment 4 positively charged, and a tube 1 through which air at zero or a negative potential is conducted into the compartment 4 where the air currents mix.  A chimney or flue 5, which may have a fan, is provided for escape of the air from the chamber.  In the construction described, the tube 1 is divided within the compartment 4 into several tubes 6 having outlet nozzles 7 all in the same plane, the outlet nozzle 8 of tube 3 being at rightangles to this plane.  A fine copper-wire gauze 10 is provided at the entrance to tube 1 which may have an earth 2 when air at zero potential is desired, or may, together with gauze 10, be charged to negative potential, for example by connection to the negative side of rectifier 11, when negatively charged air is desired.  The orifices of nozzles 7 are arranged at the corners of a regular polygon through the centre of which the axis of nozzle 8 passes, and the intensity of the treatment can be increased by diminishing the distance of the orifices of nozzles 7 from nozzles 8 and by bringing nozzle 8 nearer the plane of nozzles 7, the tube 3 being vertically adjustable. Satisfactory results are obtained when the difference in potential between the tubes 1, 3 is 200 volts.  The intensity of treatment may be regulated by varying the electric charges, the humidity, the temperature, the pressure, the velocity and the volume of the air currents.  The most favourable action is obtained by making the volume and humidity of the air current at zero or negative potential considerably greater than that of the positively charged current, the difference in humidity being obtained by artificially moistening the current by passage through a sprinkler apparatus &c., or by drying the positively charged current, or both.  In treating foodstuffs, the apparatus may be placed in the centre of a room the walls of which have shelves supporting the foodstuffs; the preserving effect is said to be radiated through the walls of the compartment 4, and the best effect obtained at a distance of about 10 metres. p
