Title: Improvements in or relating to galvanic cells
IPC: H01M4/48
Filed: 1926-07-07
Abstract: 255,067. Burgess Laboratories, Inc., C. r., (Assignees of Brown, B. K.). July 7, 1925, [Convention date]. Electrodes.-A dry cell is provided with a depolarizer consisting of solid oxidized carbon or of carbon partially oxidized with or without carbon and manganese dioxide. The oxidized carbon may be prepared by treating graphite, coke, &c. with an oxidizing agent such as a mixture of sulphuric acid with potassium chlorate or chromic acid, or a mixture of potassium chlorate, graphite and fuming nitric acid may be used. Electro-chemical means, e.g. as described in Specification 255,068, [Class 41, Electrolysis], may also be employed. A mixture of carbon and oxide of carbon may be obtained by stopping the above oxidizing processes before complete oxidation is attained. The resulting product may be ground in a ball mill. A depolarizer containing manganese dioxide may be prepared by precipitating the dioxide on to particles of oxidized carbon. This may be done by suspending oxidized carbon in a solution of potassium permanganate, nitric acid and manganese sulphate. The product, when dried, may be mixed with, graphite and ammonium chloride and moulded into shape.

Title: Stabilising system for road vehicles
IPC: B60G17/027
Filed: 1953-06-22
Abstract: 741,899. Spring suspensions; preventing lateral canting. VOGEL, A. E. June 22, 1953, No. 17305/53. Class 108 (2). A vehicle body having supporting wheels and spring means operatively connecting the body with the wheels, is combined with power means adapted to render ineffectual or partially so, the effect of the spring means at whichever side of the vehicle is near to the centre of a curve taken by the vhicle. In the arrangement shown, as applied to an independent front wheel suspension comprising for each wheel, upper and lower links 14, 15, a power cylinder 22 or 23 mounted on the vehicle and associated with a respective wheel 11 or 12, is provided with an inner diaphragm 24 dividing the cylinder into two chambers 25, 26, the diaphragm 24 being connected through a cable 27 to the lower link 15. The chamber 26 is connected to a vacuum source 40 through a valve 44 or 45, supplied from the vehicle engine intake manifold 50 through a check valve 53. The valves 44 and 45 are solenoid-operated through a manuallyoperated three-way switch 60. For automatic operation, the valves are controlled by a detector unit 65, comprising mercury switches which are operated by centrifugal force when the vehicle is rounding a curve. The unit 65 may comprise a pendulum, and preferably is of a multistage type in which the sensitivity of the unit is automatically varied in response to variations in the velocity of the vehicle. In operation, movement of the vehicle into a curve effects operation of the valve 44 or 45 associated with the cylinder on the inside of the curve to prevent the road spring 18 or 19 on that side of the vehicle from expanding to its normal uncompressed length as the vehicle tends to tilt due to centrifugal force. In another arrangement, Figs. 12-14 (not shown), the power cylinders are adapted to completely compress the appropriate road springs, this arrangement effecting a progressive lowering of the centre of gravity of the vehicle during passage of a turn. In a further arrangement, Figs. 15-18 (not shown), the power cylinders are adapted to permit complete expansion of the appropriate. spring, the weight of the vehicle at that point then being taken by engagement of a bumper on the vehicle frame with the lower suspension link. In the limiting position, the spring on the outer side of the curve becomes fully compressed, the bumper on that side of the frame then also engaging the adjacent lower link.

Class 117 A winnowing apparatus comprises a vertical duct through which the air stream rises s and an annular material entry therein, the width of which is adjusted automatically. In one embodiment, air is drawn upward through the duct 1 from a manually adjustable air intake 28 .. 31. The annular material entry is formed by the gap 33 between the lower rim of a hollow member 4, into which the material is fed through a lateral inclined duct 7, and the conical top 18 of a lower hollow member 5. The latter is kept in rotation by an internal motor 20, and is pressed upward by a lever 24 and counterweight 6. The weight of material. falling on to the conical surface 18 automatically adjusts the annular gap 33 according to requirements. The material is separated into three portions, the first heavy fraction falling into the hopper 3. A second fraction falls into an upper hopper 11 when the air velocity falls in the wider region 32 of the tunnel 1, the mouth of the hopper being covered by a perforated hood 25 of triangular semi-elliptic, parabolic &c. cross-section. The exit pipe 8 of hopper 11 is covered by a flap valve 9. The third and lightest fraction is carried by the air stream through the outlet pipe 2. In another embodiment the member 5 is not rotated and the hood 25 is replaced by a series of stepped coaxial cylindrical baffles, Fig. 2 (not shown). In the simplest embodiment the member 5 is urged upwards by a spring and no provision is made for deriving an intermediate fraction from the material, Fig. 1 (not shown).

Title: Improvements in and relating to laundry folding machines
Inventor: WOODWARD STANLEY

Filed: 1952-07-18
Abstract: 763,169. Folding sheets. BAKER PERKINS, Ltd. May 19, 1953 [July 18, 1952], No. 18187/52. Class 42 (2). [Also in Groups XXXVIII and XL (b)] In a laundry folding machine of the type in which each article is advanced to a folding station where its arrival initiates the displacement of folding means which engage the article, the arrival is detected by a photoelectric cell the illumination of which varies in a number of steps by the article to control the folding. The invention is applied to interposing the necessary delay between the detection of the article and the initiation of the folding means commensurate with the conveyer speed and the spacing between the photo-cell and the folding means. As shown, the leading edge of a sheet to be folded carried on a conventional conveyer X interrupts the first (L<SP>1</SP>) of a pair of light beams L<SP>1</SP>, L<SP>2</SP> incident on a photo-electric cell P. The increase in resistance of the cell controls the current in a pair of solenoids SOL2 and SOL3 in the anode circuit of a valve V. SOL3 is saturated and the reduction in current does not reduce its pull, whereas that of SOL2 falls appreciably. Hence, a spring-loaded switch arm is rotated from position I where it is held by SOL2 to position II where it is held by SOL3. A timing circuit commences to charge closes a holding circuit for a solenoid SOLI and continues charging until the leading edge of the sheet interrupts the record beam L<SP>2</SP> when SOL 3 also de-energizes. Switch S now moves to position III energizing relay D which then starts the timer discharging and opens one branch of a supply circuit of SOLI controlling a sheet gripping arm F. When the charge on timing circuit T has leaked away after a period proportional to the time taken by the leading edge to intercept the two light beams, contact T1 is opened, opening the other branch of the circuit of SOL1 which is de-energized. Arm F is now moved by spring M to grip the leading edge of the sheet. The conveyer continues running, thus forming the fold in the sheet. When the trailing edge of the article is carried clear of the first light beam switch S moves back to position II breaking the circuit of relay D energizing solenoid SOL1 which releases the leading edge of the article so that it falls on the trailing edge. When the trailing edge clears beam l<SP>2</SP>, switch S is restored to position I. Specifications 618,157, 754,109 and 763,170, [Group XXXVIII] are referred to.
