Rotating-tool machines; staking; stretching by tension.-A rotary staking-machine has a pair of intermeshing rolls 1, 2 between which the leather &c. is drawn by hand or mechanically, as by wrapping round a draw-roll 22. The rolls are mounted in end frames 3. 4, the upper roll 1 being carried by arms 6 keyed to a short shaft 7 adapted to be rocked to raise the roll by a treadle 12 acting through a link 11, rock-shaft 10 with counterweight 13, connecting-link 9, and arm 8. The upper roll descends by gravity or under the influence of springs and an adjustable stop may regulate the working position. In the end frame 4, the rolls are supported in bearings 14, 15, the upper bearing 14 being supported by a spring 17 and movable up and down within the guide-frame 16. The lower roll is driven by the main shaft 28 through gears 29, 30. A second pinion on the shaft 28 drives the upper roll 1 at the same speed in the opposite direction through an intermediate pinion 32 carried by the arm 6. The blades 18 on the upper roll may be straight or double helical and may engage corresponding grooves 19 in the lower roll, as shown in rigs. 1 and 6 or, alternatively, may intermesh with similarlyshaped blades on the lower roll. The rolls are removable and may be replaced by other rolls having different blades. The draw roll 22 may be formed with a hinged bar 23 having hooks 24 to which the end of the hide may be attached, or a clip or clamp device may be provided on the draw roll for this purpose. The draw roll may be rotated by a handle 25 through worm gearing 26, or it may be driven by gearing and controlled by a treadle in connection with or independently of the working rolls. The Provisional Specification describes also an arrangement in which the draw roll is supported by spring controlled levers or oscillating arms actuated by power or a treadle. Reference has been directed by the Comptroller to Specifications 1961/71, 20273/97, and 15941/12.

Title: Regulation of power supply systems
IPC: H02M3/156
Filed: 1962-08-27
Abstract: 1, 021, 811. Automatic voltage control. WESTERN ELECTRIC CO. Inc. Aug. 27,1962 [Sept. 29,1961 (2)], No. 32793/62. Heading G3R. Also in Division H3] A power supply regulating circuit comprises a voltage source 1, a load 2, a series switching transistor 7, and a regenerative feedback network including a transformer 4 which is associated with an inductor 3 and impedance elements 8, 9, 10 to control the periods of conduction and non-conduction of the transistor 7. In operation, a small current initially flows through the collector/emitter path of transistor 7 and the load when the voltage source is applied to the circuit; this current also flows through transformer winding 5, which has a much lower impedance than inductor 3, whereby a voltage is induced in winding 6 tending to drive transistor 7 further into conduction. The current flowing through inductor 3 then increases with time and the current through winding 5 decreases accordingly until transistor 7 is driven out of the saturation region; the current through inductor 3 then starts to decrease, the associated flux collapses, and a current is induced in winding 5 to oppose the load current, the current flowing through the components 9,10 being such as to bias the transistor 7 to cut-off; the cycle will start again when the energy in inductor 3 is dissipated. The "off" time of transistor 7 is controlled by varying the impedance of the elements associated with the winding 6. The series transistor may be controlled in dependence upon output voltage variations (Fig. 3 not shown), and the circuit may include further amplifying and control transistors associated with a further transformer winding (Figs. 4 and 5, not shown). An embodiment including temperature compensating and protective circuits for the series transistor is described with reference to Fig. 6 (not shown). Mechanical or pnpn switches may replace the series transistor as a switching element.

Title: Improvements in non-spilling electrical accumulators
IPC: H01M50/529
Filed: 1938-11-15
Abstract: 512,741. Batteries. FABBRICA ITALIANA MAGNETI MARELLI. Nov. 15, 1938, No. 33239. Convention date, Nov. 17, 1937. [Class 53] An invertible accumulator, having a vent plug whose inner orifice is always outside the mass of liquid in the container irrespective of the position of the latter, has a channelshaped screen mounted around the plug in a hollow cover without forming a tight closure to prevent too rapid transfer of electrolyte. A container 1, Fig 1, is closed by a hollow lid 2 in which is a vent plug consisting of a collar 9 having an inwardly projecting nosepiece 10 through which passes a conduit 11. Around this nose-piece 10 is a chamber 13 formed by a member 12 in the lower end of which is a communicating hole 14. At the upper end of the plug is a chamber 15 closed by a further member 16 having a hole 19 communicating with a depression 20. Around the plug is a channel-shaped screen 21 so designed as to allow only a small space between itself and the side walls of the container so that, when the cell is inverted, the transfer of the electrolyte takes place comparatively slowly. The position of the vent hole 14 is such that it is always above the levels L, L<1> of the electrolyte in the normal and inverted positions respectively. In order that the upper electrolyte space may be of convenient shape and volume, the cell is made as shallow as possible and for this purpose the plates 4 are made broad in relation to their height and to overcome the resultant increase in resistance additional ribs 4<11> are provided radiating from the terminal post 4. Where a number of cells are employed side by side in one block the electrical connections between adjacent cells may be made through the separating walls, Fig. 4 (not shown). To enable the correct level of electrolyte to be maintained, the screen 21 may have depressions 21<1> formed in its lower surface in which electrolyte will lie when the level is correct and which may be observed by removing the vent plug 9. Alternatively a suitably placed observation window may be mounted in a side wall of the container, Fig. 3 (not shown).
