Abstract: 172,641. Seigneur, L. Dec. 9, 1920, [Convention date]. Addition to 145,695. Clutches, friction.-In expanding-band friction clutches, balls or rollers d are carried in slots in a sleeve c secured to the driven shaft a and are pressed by a sliding cone sleeve connected by rods i to the clutch collar g into contact with 7 cam surfaces x on loose blocks e retained laterally in position by an encircling wire k and bearing against one or more clutch bands f engaging the driving-pulley b, the elasticity of the bands f being so calculated as to balance the action of centrifugal force. The bands are forced against the pulley b, the clutching action being increased automatically if slip occurs by the action of the cam surfaces x. The sleeve c is secured to the shaft bv grub screws and is moved into and out of working position on a sliding ball-race. The Specification as open to inspection under Sect. 91 (3) (a) states that two or more concentric bands f may be used, or a single band may be subdivided into several parts. This subjectmatter does not appear in the Specification as accepted.

Title: Electrolytic plating
Inventor: MANSON WALTER J
IPC: B21C47/26
Filed: 1963-05-06
Abstract: In the electroplating e.g. with copper of linear conducting material such as steel wire or strip formed into a helix supported on at least two similar parallel rotating metal rollers which continuously advance the helix axially as in Specification 857,351, the cathodic connection to the helix is made through at least one of the rollers at points spaced by several turns of the helix through sliding contacts, the rollers being continuously supplied with water as by spraying e.g. from pipe 71 Fig. 5 (not shown) adjacent the contacts and wetted with the plating bath, again as by spraying from pipes 39, 40 Figs. 1, 3, 5 (not shown), elsewhere. As described the rollers are of steel wrapped with a brass tape.  The helix travels through anodic cleaning, detergent cleaning, and dilute sulphuric acid baths with intermediate rinsing baths before entering the plating bath.  Over the pretreatment baths the rollers are sprayed with water from pipes 30, 31 and the drips are directed by pans into the rinsing baths (see Figs. 1, 4 not shown). Between the dilute sulphuric acid and plating baths the rinsing bath container 25-1 is formed of an elastomeric material and provided with an arched bottom to permit deformation to assist in aligning the bath containers.  On leaving the electroplating bath the helix is sprayed with water to wash off adhering plating electrolyte.

Abstract: 445,072. Rotary engines. HOLZKNECHT, F., 509, Richards Street, Vancouver, Canada. June 22, 1935, No. 18005. [Class 110 (ii)] A rotary engine comprises a rotor 5 with pistons 22 which move around an annular chamber 6, and co-operate with recesses 17 in abutments 15. Pinions 17 on the latter are geared to a toothed driving wheel 21. An annular space 7 in the rotor allows working fluid to pass from an inlet 9 to passages 10 into the chamber 6. A similar space 8 allows exhaust fluid to flow from the chamber 6 through passages 11 to an exhaust port 13. Segmental casing walls 23 act as seals when the pistons are passing through recesses 17. Spring-pressed packing rings 20 are provided. The working fluid, which may be steam, exerts a force on the teeth of pinions 17 helping to drive them in an anticlockwise direction. In a modification the spaces 7, 8, communicate with each other through ports in the rotor. Conduits in the pistons allow working fluid to pass from the spaces 7, 8, to the chamber 6, and exhaust ports from the latter lead to an exhaust manifold.

[Class 40 (ii).] Apparatus for reproducing combined sound and picture films is provided with a sound gate m which is adapted to be reversed so that light may be projected through the sound record when the latter is on the right-hand side or left-hand side of the film according to whether the film is turned to suit projection of the picture on the front or rear of the screen. The gate m is connected by spring bolts n at each side to a member l which is slidably mounted on a dovetail guide k on a bracket h, as shown in Figs. 1, 2, and 3. A light slit m<1> in the gate in coincides with an aperture l<1> in the member l, and these apertures are adapted to be aligned with either of two apertures i, j in the bracket h. The spring bolts n enable the gate m to be swung to either side by releasing the corresponding bolts. The lens system is mounted on a plate o slidable on the opposite side of the bracket h to that on which the film gate m and member l are mounted. When the projection of the picture is changed from one side of the screen to the other, the member l and gate m are withdrawn and also the plate o, and these members are reversed end for end and replaced so that the apertures l<1>, m<1> become coaxial with the correct apertures i, j.

Abstract: 959,467. Opening, cleaning and drawing fibres; depositing fibres in containers. H. TRUTZSCHLER, and H. TRUTZSCHLER, [trading as TRUTZSCHLER & CO.]. May 18, 1961, No. 18190/61. Headings D1D, D1F and D1N. A machine for opening and cleaning cotton has a plurality of striker cylinders operating in parallel, each cylinder being fed from an individual feed trunk arranged to receive cotton from a common conveyer. The feed trunks 5 receive fibres from a spiked lattice 4 that, in turn, receives material from a hopper 1 equipped with a photocell 2 that controlls the stopping and starting of a preceding conveyer according to the height of the material in the hopper 1. Another photo-cell 6 is mounted in the final trunk 5 to be filled by the lattice 4 and, when this trunk is full, the lattice 4 is stopped. From the trunks 5 the fibres are fed by rollers 7 and cylinder and shoe units 8, 9 to the striker cylinders 11 with which are associated bars 12 that intercept ejected dirt while the fibres pass on to suction cages 15 from which they are stripped by rollers 18 delivering to a lattice 19 on which fibre webs are superimposed. The lap of superimposed webs is subjected to a draft of from 10 to 40% or more and uniformity of lap may be obtained by controlling the roller speeds by a condenser tester 22. As the lap leaves the rollers 24, it is deposited in a bin 27 that has a movable floor 26 which is initially raised to the upper edge of the bin and is lowered as lap is deposited. At the sar e time, the bin 27 is reciprocated on rails 29. When the bin is full it is moved under another bin 30 closed at the top but with a sliding bottom that can be opened for the reception of the contents of the bin 27.
