IPC: A41H9/02
Filed: 1918-12-24
Abstract: 122,824. Kessler, C. H. Feb. 1, 1918, [Convention date]. Measuring for.-A device by which the required length of a skirt may be correctly indicated by the wearer without assistance consists essentiallv of two combined measuring rods and a spring device for holding a tell-tale, such as a pin, at any desired height, the arrangement being such that by rotating the rod the pin can be driven into the fabric at the desired place and, by pressing on the rods, be left in that position. The rods consist of two similar bars 1, 2, separate from each other but provided with end caps 3, the bar 1 being connected to the bottom cap and the bar 2 to the upper cap. A pin 5 in each bar works in a slot 4 in the cap of the other bar, and a spring 6 connected,to both rods, allows the bars to slide on one another, but normally tends to separate them. Two bands 11, 12 are secured respectively to the two bars at the desired points by set screws 9, 10. The band 11 carries a housing 14 having a central horizontal slot 15 and an end notch 16, and within it is a frame 17 carried by the band 12. The frame has a cross recess 18, a recess 20 at one end, a transverse slot 21 in each side at the other end, and lateral openings 22 in each side, each provided with a seat 23 at its top. A latch 24 pivoted at 25 to the housing has arms lying in the slot 21, and a free end 26 drawn up by a tension spring 27. The latch also has arms extending into the openings 22. To use the de. vice, the wearer of the skirt adjusts the bands 11, 12 so that the slot 15 is at the required height from the ground, presses on the top of the rods whereby the bands separate slightly, allowing a pin to be placed and gripped in the slot 15, as shown in Fig. 5, by the shoulder 19 of the recess 18. She then puts the lower end of the rods on the ground against the dress, and rotates the rods so that the pin passes through the material and out again. By pressing again on the top of the row, the pin is released therefrom and is left at the desired place. By repeating this process, as many pins as desired may be inserted in the dress by the wearer at the same height.

Abstract: 635,023. Manually-actuated multiple-way valves ; fluid-pressure servomotor systems. ELECTROFLO METERS CO., Ltd. Aug. 8, 1947, No. 21825. Convention date, Feb. 13, 1943. [Class 135] A valve 25 for switching from " automatic " to " manual " working in a servomotor system comprises a ported sleeve 33 which, in one position, allows of intercommunication between some conduits connected to the casing of the valve and, in another position, interrupts such intercommunication and connects certain of the conduits to a longitudinal bore in the sleeve which houses a further valve member 44 controlling the ports in the sleeve. The valve 25 is situated between the automaticallyactuated pilot valve 10 of the system and the servomotor 21. When a handle 36 connected to the sleeve is moved to the position to allow the servomotor to be automatically controlled, the sleeve is rotated and slots therein interconnect lines 26 and 27 around the lands on valve member 44 so that the servomotor will come under the direct control of pilot valve 10. When the sleeve is rotated to the " manual " position communication between lines 26 and 27 is cut off and ports in the sleeve allow the fluid-pressure supply line 28, a drain line 31, and lines 27 to communicate with the interior of the sleeve and the servomotor is then controlled by sliding valve member 44 backwards or forwards by means of its operating knob 45. When released, valve member 44 is centred by means of a spring 46.

Title: Imprvoements in and relating to processes for the protection of electrical contacts
IPC: H01H1/60
Filed: 1964-05-28
Abstract: The surfaces surrounding the actual contact surfaces of constructional elements having electrical contacts are coated with a protective layer of a solid polymeric compound which contains Si-O bonds.  This minimises the migration of corrosion and fowling-producing contaminants from the body of the apparatus concerned.  The process is applicable to relays in communication and control apparatus.  The coating may be produced from a dilute solution of a silicone resin in perchloroethylene, which is applied by a cloth to the whole contact and subsequently removed by a file from the actual contact surface.  Metal salts of organic acids (e.g. cobalt, lead or tin naphthenate maleate or octoate) may be included as catalysts.

Title: Improvements in or relating to circuit arrangements for disconnecting high-voltage direct current circuits
Inventor: FAUST WERNER
IPC: H01H9/54
Filed: 1971-04-19
Abstract: 1291686 Arc preventing in switches BROWN BOVERI & CO Ltd 19 April 1971 [20 Feb 1970] 22112/71 Heading H1N A high voltage direct-current switching arrangement includes a series combination of an even number of controllable electronic valves T 1 , T 2 , ... T n  poled in the forward direction, a resistor R 1 , R 2 , ... R n-1  being connected in shunt with each of the said valves T 1  to T n-1  but not valve T n  which is furthest from the positive pole of the circuit, the series combination being connected in series with one isolating switch S2 and shunted by another isolating switch S1. To interrupt the circuit the switch S is opened as all the valves T 1  to T n  are turned on so that the load current passes through the values T 1  to T n . An auxiliary valve H 1  is turned on so that a capacitor C 1  discharges in opposition to the load current in T 1  which is extinguished. The load current flows through the valve H 1  until the capacitor C 1  is charged and valve H 1  is cut off and R 1  comes into circuit. Valve H 2  is now turned on so that the capacitor C 1  discharges against the load current in T 2  which is extinguished, so that current passes through valve H 2  until capacitor C 1  is charged and resistor R 2  comes into circuit. This sequence is repeated until H n  is switched on to discharge capacitor C n/2  through valve T n  which switches off to pass load current through all the resistors, valve H n  and a resistor R K  until C n/2  is charged and isolating switch S 2  can be opened on no load. The capacitors may be provided with series resistors to limit the rate of current rise and the valve circuits may be connected by a diode bridge to prevent current reversal (Fig. 2, not shown). The valves may be protected by inductors in series with the auxiliary valves (Fig. 3, not shown).

A hop picking machine has a holder for detached bines which locates them opposite pickers each comprising a helix between whose convolutions stalks can be drawn but not hops. The holder may comprise a helical spring, which is stretched and then released to grip bines between its convolutions. A modified form of the machine described in Specification 449,535 comprises a picker conveyer 10, Fig. 4, having two endless chains which pass round sprockets 11 and 12, and an overhead bine conveyer 13 provided with a wire spring holder 15 for traversing bines across the picker conveyer and mechanism 16 for swinging them towards and away from it. Picked hops are carried away by a conveyer 14. The spring 15 may be endless and may pass round a driving pulley. Links 17 in the endless chains, Fig. 1, each carry a bracket 18 to which an arm 19 is secured. Each arm is connected to the corresponding arm of the other chain by a stay 20 and stretched between the arms is a helical spring 24, constituting a main picker. A crimped stranded steel wire 26 carried between the arms and passing through the spring prevents it being stretched unduly. The stays 20 have arms 29 bearing flexible strips 30 to which auxiliary pickers 28 are secured by screws 38. Each picker 28 comprises two substantially triangular plates 31 clamped together by the screws 38. A helical spring 33 extends around the plates and is held in position by lugs 32 thereon. Passing through the spring 33 is a crimped stranded steel wire 34 whose ends are secured by a set screw 36. The Provisiona Specification also describes a machine in which hop bines are fed onto a horizontal platform made up of fixed parallel rods. In or slightly above each space between the rods is the lower run of an endless spring which passes around pulleys at each end of the platform. The pulleys at one or both ends may be driven. The springs carry the bines along the rods and the hops droop below the springs. Another endless spring passing round pulleys at each end of the platform is located slightly below each firstmentioned spring. Each lower spring may be driven so that its upper reach moves in the same direction but faster than the lower reach of the upper spring.

Filed: 1964-05-28
Abstract: 1,025,779. Wells. CAMCO Inc. May 28, 1964 [Sept. 13, 1963], No. 22177/64. Heading E1F. In equipment for positioning and setting a well packer 11 comprising a cylinder 22 and piston 10, the sides of the piston within and without the cylinder are both exposed to well fluid pressure until the packer is to be set by lowering down the tubing string 2 and associated mandrel 3 a setting tool 40 which includes a depression chamber 41 of relatively low internal pressure, initially sealed by a pin 49 (Fig. 2) into which fluid from the cylinder 22 flows to equalize pressure in the cylinder 22 and chamber 41 on knocking-out the pin 49, whereupon the higher pressure existing at the upper end of the piston urges it downwardly. Slips 19, 33 are then sequentially urged by the piston against the bore wall 1 to axially compress the packer (Fig. 2). The pin 49 is knocked out by a plunger 54 actuated by firing a cartridge 58 as disclosed in Specification. 907,530. In its descent the plunger forces dogs 44 on the tool 40 into a keeper groove in the mandrel 3 to latch tool and mandrel together. In one embodiment (Figs. 6A, 6B, not shown) the packer is unrecoverable and the tubing string is detachable therefrom but in the embodiment shown in Figs. 1 and 2 both packer 11 and tubing string 2 are recoverable by rotating the string to release the mandrel 3 from a clutch collar 26, and lifting the mandrel to bring it into contact with a shoulder 65 and so lift the piston thereby releasing the slips 33 and 19 and allowing the packer 11 to elongate axially, all the collapsed parts then riding up with the string.

IPC: B60Q1/38
Filed: 1971-04-19
Abstract: 1305317 Thermal switches; electromagnetic switches; continuous interrupters WAGNER ELECTRIC CORP 19 April 1971 [24 Feb 1970] 22309/71 Heading H1N Three electrically operated switches 12, 22, 40 are arranged and connected to form a flasher unit whose on-off periods are substantially independent of supply voltage or load current. The switch 12 is a series flasher unit comprising an expansible strip 17 heated by the load current flowing through it to operate a snap acting strip 14 and thus open contacts 18, 20. The switch 40 comprises a spring blade contact 46 operated by an electromagnet 42 in series with switch 12. Switch 22 comprises a spring blade contact 24 normally held open by an expansible wire 26 connected in series with a ballast resistor 38 across switch 12; the electromagnet 42 serves also to hold contacts 24, 32 of switch 22 closed until wire 26 is sufficiently cooled. When the external circuit is closed strip 17 is heated until contacts 18, 20 open; they remain open for a fixed time determined by the cooling of strip 17; this is the off-time of the flasher unit. While contacts 18, 20 are open wire 26 is heated and contacts 32, 34 are closed by it. When the contacts 18, 20 reclose the magnet 42 closes contacts 48, 50 completing a shunt circuit around switch 12 so that strip 17 is not heated. After a time, dependent on the energy supplied to it while contacts 18, 20 were open, the wire 26 opens contacts 32, 34 to break the shunt circuit. Strip 17 then heats up to open contacts 18, 20 again. The on-time of the flasher unit is thus the sum of the cooling time of wire 26, which increases with increasing load current, and the heating time of strip 17, which decreases; the total on-time is thus substantially constant.
