Both wheels are grooved at 6<SP>1</SP>, 7<SP>1</SP> to receive the solder wire. In a modification the bit is replaced by a rod bent to hairpin form and connected to a transformer, housed in the upper part of the housing, a lamp indicating when the transformer is energized. In further embodiments the irons above described are modified and each is provided with an electric motor in the housing which is arranged to drive the shaft 16 when a switch is closed so that the solder wire may be fed by the motor or manually by rotating the wheel 5. In the iron having the hairpin shaped bit the spool is arranged in the housing above the handgrip with the motor in the hand-grip.

Title: Hydraulic valves for use with reciprocating mechanisms
IPC: F03C1/14
Filed: 1970-10-08
Abstract: 1373098 Percussive tools A F HYDRAULICS Ltd 7 Jan 1972 [8 Oct 1970] 47867/70 Heading B4C [Also in Division F1] A valve assembly for supplying alternating flow to the pressure chamber C of a road hammer H comprises resiliently loaded main and auxiliary valve members 7, 13 automatically reciprocable in a valve body 1 to cause alternate pressurization and depressurization of an outlet 25 to the hammer H. The main valve member 7 reciprocates in a bore 2 provided with an inlet port 18, an outlet port 19 and an intermediate exhaust port 20. When the inlet port 18 is pressurized, liquid flows through a passage 23 and an axial bore 8 in the member 7. This causes lifting of the auxiliary valve 13 and consequential flow to the outlet 25. Eventually a pressure builds up in the outlet 25 which is sufficient to displace the member 7 against the bias of a spring 6. As a result the exhaust port 19 is uncovered to allow the outlet to exhaust; inlet port 18 is closed; and the intermediate exhaust port 20 aligns with a passage 24 to allow the escape of liquid trapped in a chamber 5. The collapse of pressure in the outlet 25 allows the spring 6 to return the member 7 to its original position and the cycle is repeated. A second embodiment is described in which the valve member 7 is biased hydraulically and the auxiliary valve 13 is disposed in a flow passage in the body 1 and not in the member 7.

Abstract: 1368905 Furniture joints HUWIL-WERKE GmbH 20 Oct 1972 [10 Nov 1971] 48355/72 Heading F2M A connection fitting for furniture, particularly for connecting together two panels 1, 2 at right angles, consists of a moulding of resilient, e.g plastics, material comprising a flange 7 having integrally formed therewith a cylindrical housing 3 and a stud 6 both of which are, in use, let into one panel 1 as shown so that the axis of the housing 3 is coaxial with a bore 20 in the panel, the housing 3 having a coaxial bore in which a rotatable member 4 having an eccentric internal camming surface is made captive, the camming surface being adapted to engage under the bead of a stud 5 previously fitted to the other panel 2, so that upon rotation of member 4 from a predetermined start position the panels are drawn together. The start position is preferably determined by a bead on the internal wall of the housing engaging resiliently within a notch 10 in the member 4. Rotation of member 4 is effected by inserting a tool through bore 20 in the panel from either side into a corresponding one of two screwdriver slots 18, 19 in the ends of the members 4. As seen in Fig. 4 the member 4 has a cut-away portion to receive the bead of the stud 5, a slot 15 being also provided in the flange 7 for this purpose. Member 4 is made captive in the housing bore by projections 8 on its periphery which snap into an undercut portion of the bore.

Title: Apparatus for visually displaying an analogue of a measured parameter and a combination of such display apparatus with means for forming the analogue
IPC: G01R13/40
Filed: 1973-10-17
Abstract: 1452825 Control of displays ALFRED HERBERT Ltd 17 Oct 1973 48453/73 Heading G4H The analogue output of a transducer 1 is sampled by pulses from a generator 3 and displayed on a "centre-zero" column display of light emitting diodes. An oscillator 2 excites 1 and drives generator 3, the oscillator waveform being sampled at 5 to produce (with inverter 8) positive and negative reference signals which are fed via a switch S1 to series resistors 13 which provide reference voltage inputs to comparators 14. The LEDs are arranged in two groups forming the upper and lower halves of a column, and the output from each comparator is fed to one diode in each group. The groups are grounded via switch 16 (switched at 50 Hz with 51) and the normally closed contact of relay 12. Those comparators whose reference voltage is below the signal voltage have high outputs which illuminate the corresponding diodes; the two diodes associated with the lowest reference voltages are at the centre of the column. Potentiometers 10 may be set to provide upper and lower tolerance limits, the voltages therefrom being compared at 11 with the signal voltage: if this goes out of tolerance, the contact of relay 12 opens and the lights are caused to flash through the action of switch S2B which is opened and closed at 4 Hz. Switch S3A may be moved to the "set" position to disable the above out of tolerance indication and to indicate the upper and lower tolerance limits: S3B shorts out S2B and 12, while S3A connects comparators 14 to S2A (switched at 4 Hz). All the diodes below the lower limit are illuminated for half the 4 Hz cycle, and all those below the upper limit are illuminated for the other half cycle: thus the diodes below the lower limit appear to be continuously illuminated, those between the limits flash, and those above the upper limit are not illuminated. Alternatively, the in-tolerance zone may be indicated by a solid band of light, the out of tolerance zones being dark. Switches S1 S2 may be F.E.T.s, and 1 may be an inductor with a displaceable core whose position depends on the parameter to be measured, e.g. dimension of an article.

Switch 10 includes a housing of an openended insulating tubular sleeve 16 with two closure end plates 12, 14, of electrically and thermally conductive material, and a composite thermally responsive snap-acting element 32 urged by a conductive spring member 24 towards an annular abutment 40 of insulating material, the movable switch contact 34 being carried by the element 32 for engagement with a fixed contact 36 on or provided by plate 12. The thickness of abutment 40 is chosen to allow creep action movement but to prevent or inhibit creep action opening of the contacts 34, 36, prior to snap-action of the snap-acting bi-metal disc 32. Plates 12, 14, are of silver, brass or cold-rolled steel coated or plated with silver or gold alloy. Spring member 24 has stuck-out spring fingers 26, 28, 30, and is of beryllium copper. A circumferentially extending metal layer 22 of readily solderable molybdenum-manganese alloy is bonded or deposited on the ends of sleeve 16 to facilitate assembly under pressure of the switch parts and sealing thereof by immersing in molten solder, solidifying at 44 and 46. The assembled switch 10 is encapsulated in epoxy resin.

The lower pressure source is vacuum produced by means of a connection to the vehicle engine inlet manifold and the higher pressure source is atmospheric air. When an electronic control unit 92 senses an incipient skidding condition an output signal therefrom actuates a solenoid 90 to open valve 84 and supply atmospheric air to cavity 48 causing the piston 78 to move a valve member 72 from a seat 74, air also being supplied via port 56 to chamber 30. Chamber 28 is connected to vacuum via port 60 and chamber 52 so that the piston 32 of the modulator is moved to allow a valve 20 to close to prevent further supply of braking pressure while such movement increases the volume available to the fluid in the brake cylinders with consequent reduction of braking pressure.

In winter operation cold air is passed by a fan 2A over the heat exchanger 4A operating as an evaporator and heated air is exhausted by a fan 2B after passing over the exchanger 4B acting as a condenser by a fan 2B according to the setting of the valve 22.

In summer operation, high pressure vapour from the compressor passes through the altered position of the switch 22 via the valve 18 to the exchanger 4A acting as a condenser, and the resultant high pressure liquid passes via the valve 10, and accumulator 12 for heat exchange to the pressure reducer 14 and thereafter as low pressure liquid via a valve 32 to the exchanger 4B acting as an evaporator for eventual return as low pressure vapour through the valve 26 and switch 22 to the accumulator 12 for recirculation. The valves may be formed as non-return spring biased valves openable at predetermined pressure differentials across the valves.
