Patent FR-1323261-A (FR)
IPC: G01R31/36
Filed: 1962-05-10
Granted: 1963-04-05
Abstract: 971, 128. Testing batteries GLOBEUNION Inc. May 18, 1962, No. 19193/62. Heading G1U. In an apparatus for indicating undercharge of a storage battery 10 a voltage sensitive relay 26 in series with a switch 16 is connected across the battery, normally closed contacts 28 operated by the relay are connected in series with the switch and in parallel with the relay and connected in series with an indicator lamp 20, and a temperature compensating means consisting of a thermister 30 in parallel with a resistance 32 is connected in series with the relay to compensate at least partly for variations in the operating voltage of the relay with temperature. The arrangement is such that the voltage sensitive relay is energized on closing the switch 16 only if the battery voltage is above a predetermined amount, otherwise the contacts 28 remain closed and the indicator light is illuminated to show an under-charged condition- The apparatus is particularly applicable for use with a battery in the ignition circuit of an internal combustion engine having a generator 12 and a regulator 14 and as described may also include an arrangement for dissipating surface charge on the plates of the battery prior to making the test so as to avoid errors due to this cause. An additional set of contacts 34 operated by the relay are included, and a thermal switch 58 energized by the generator 12. With the engine running, the thermal switch 58 is closed, but the contacts 34 will be open. If the switch 16 is now opened to switch off the engine, the contacts 34 close and the surface charge on the battery plates discharges through the thermal switch, until this has cooled sufficiently to open, into the 75 watt resistor 38. With the surface charge thus dissipated, operation of the switch 16 will enable the true electrochemical condition of the battery to be determined.

Filed: 1954-01-15
Abstract: 755,107. Syphons. BALFOUR, BEATTY & CO., Ltd., and MACKICHAN, R. W. A. Dec. 16, 1954 [Jan. 15, 1954], No. 1296/54. Class 69(1). In syphon apparatus arranged to come into operation automatically when the water level in a reservoir, pond or tank 11 rises to a certain high level and to stop when it falls to a lower level, a mechanism is adapted to open a gate 15 through a, cable 23 at the high level to admit water to seal the throat 20 of the syphon which then primes itself, and to close the gate at the lower level thereby shutting off the water from the sealing basin 12 and admitting air to the syphon throat to stop the flow. The movement of the gate 15 may be controlled by a hollow piston moving in a cylinder and being partially filled with water overflowing from a weir; as the water level rises the rate of overflow increases to increase the weight of water in the piston and cause it to fall under the increased weight to open the gate. When the gate 15 is subsequently closed, the basin 12 empties through a drain 36.

Title: An improved process of forming cakes of soap
IPC: C11D13/12
Filed: 1922-01-18
Abstract: 174,349. Crouch, M. La F. Jan. 20, 1921, [Convention date]. Endless-chain machines; casting soap; cooling-apparatus. -- Soap is formed into cakes by dividing a batch of hot semi-liquid soap into appropriate porticns, congealing or freezing the exterior layer of each portion, by subjecting it to surrounding conditions of progressively lower temperature preferably followed by surrounding conditions of progressively higher temperature, and allowing the interior to congeal by heat transference to the outer layer. An apparatus for carrying out the process comprises an endless chain of moulds B adapted to receive molten soap from a crutcher A and which traverse a divided casing G where, firstly, a spray of brine at a temperature of about 38‹ F. is directed through pipes I against the bottoms and sides of the moulds, next, a stream of brine at a temperature of about 18‹ F. is allowed to flow over a baffle H on to the upper surface of the moulds and into direct contact with the soap, and finally the top and bottom sides and ends are sprayed with brine at a temperature of about 18‹ F. through pipes I<1>, I<2>. The brine falls on to the return run of the mould chain which traverses a tank S from which the brine is withdrawn and again circulated through the pipes I, I<1>, I<2>. The brine in the tank S also serves to retain the cakes in the moulds. The brine sprayed through the pipes I falling into the tank S warms the moulds prior to discharge and re-filling. The congealed cakes of soap are delivered on to a carrier &c., where they are first washed with fresh water sprayed through a pipe P', then subjected to an air blast to remove surface water, and are finally delivered to a tempering chamber, where the cakes are allowed to set and are also dried by air currents. The cakes may then be pressed.
Patent GB-468969-A (GB)
Title: Improvements in or relating to variable-speed gearing
IPC: B62M9/12
Filed: 1936-01-17
Abstract: 468,969. Variable-speed gearing. FROST, S. J. Jan. 17, 1936, Nos. 1610 and 23652. [Class 80 (ii)] A two-speed gear particularly for cycles comprises two chain sprockets 12, 17 driven at different speeds from a pedal crank having two co-operating sprockets and connecting chains. The high-speed sprocket 17 drives, through dogs 19 and 20 allowing a certain amount of lost motion, a ratchet wheel 18, with teeth 21, which drives the wheel hub 8 of the bicycle by means of a spring-loaded pawl 34. The low-speed sprocket 12 drives through. a freewheel device 14, a sleeve 10 carrying a cam member 16 with cam slopes 28 and 37. For the low-speed drive a pocket 41 in the cam slope 28 engages a roller 27 on a lever 26 pivotally mounted on the hub 8, the high-speed pawl being lifted from engagement by the cam 37 when this occurs. The lever 26 is biassed against a stop 31 by a tension spring 30 and a considerable force is required to force the roller 27 up the cam slope 28, against the spring 30 for the positive engagement of the low speed drive. Thus, on backpedalling or momentarily free-wheeling in high or low gear, the driving force is relieved and the pawl 34 overruns or due to the lostmotion connection of the dogs 19, 20 the roller 27 moves down the cam slope 28, until the lever 26 comes against the stop 31. On resuming the drive, if high gear is desired a comparatively gentle pedalling effort is made which is insufficient to lift the lever 26 and therefore the pawl 34 so that the high-speed pawl 34 drives, the cam 16 being carried around by a shoulder 40 on the lever 26 at a greater speed than the sprocket 12, which is allowed by the freewheel 14. The drive is then positive and any effort can be exerted on the pedals without effecting a change of speed. If however, on resuming the drive, a considerable pedalling effort is made, the roller 27 is forced up the cam slope 28 into its low-speed driving position and the pawl 34 is lifted out of engagement by the cam 37, the sprocket 12 thus taking up the low-speed drive, which is maintained until another freewheeling or back-pedalling movement is made. The freewheel device 14 and the pawl 34 provide freewheeling from either gear and to enable a fixed wheel action to be obtained when desired a set of dogs 22 is provided on the ratchet wheel 18 which are adapted to be engaged by a tongue 29 on the lever 26 when the stop 31 is removed. High or low gear can still be engaged in the normal manner, but on attempting to freewheel the tongue 29 positively engages the dogs 22.
