Title: Improvements in or relating to pressure controlling apparatus
IPC: B29C48/00
Filed: 1954-11-29
Abstract: 754,922. Fluid-pressure servomotor-control systems. EDISON SWAN ELECTRIC CO., Ltd. Nov. 29, 1954 (Dec. 2, 1953], No. 34544/54. Class 135. Apparatus for maintaining substantial pressure balance between liquid and gas or vapour contained under pressure in respective chambers communicating with each other through a small aperture comprises a regulator controlling the pressure of liquid or gas as admitted to the appertaining chamber and itself controlled in accordance with a liquid level varying in dependence on the relative value of the gas and liquid pressures. As shown, the apparatus is applied to vulcanizing plant for the rubber sheathing of electric cables in which the cable 15 is passed firstly through a chamber 2 containing steam for vulcanizing, then through a partition 14 to a chamber 3 containing water for cooling the cable before it passes out of the plant. Water is supplied to the chamber 3 through a valve 17 which is actuated by a diaphragm 16 subject on its upper surface to the pressure of water in the chamber 3 through a conduit 18 and on its lower surface to the pressure of steam in the chamber 2. The upper side of the diaphragm 16 also communicates through a conduit 19 and an electrically actuated valve 9 with atmosphere. The winding 21 of the valve 9 is supplied through a relay 10 the winding of which is connected in series with the secondary of a transformer 11 and an electrode 12 in the steam chamber 2. When there is sufficient condensate in the chamber 2 to make contact with the electrode 12 to complete the circuit through the relay winding the winding 21 is de-energized so that the valve 9 is closed and the diaphragm 16 is in balance between the steam and water pressures. Should the pressure in the chamber 2 exceed that in the chamber 3 some vapour will pass from the chamber 2 to the chamber 3 resulting in the revaporization of some of the condensate causing the circuit containing the relay winding to be opened and the winding 21 to be energized to open the valve 9 and thereby reduce the pressure above the diaphragm 16 and cause the valve 17 to open to admit more water to the chamber 3 to equalize the pressures. The water pressure will continue to rise until it causes an accumulation of condensate in the steam chamber to make contact with electrode 12.

IPC: H01F7/02
Filed: 1953-12-11
Abstract: 759,389. Magnetic couplings. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 11, 1953 [Dec. 16, 1952], No. 34569/53. Class 35. A magnetic coupling comprises at least one member having a number of thin permanent magnets 1 arranged radially to a pitch circle T and so magnetized that the surfaces of adjacent magnets facing each other have the same polarity, the surfaces of each pair of adjacent magnets being separated by thin bodies 2 of ferro-magnetic material and the pitch distance t between the bodies 2 being smaller than any longitudinal dimension of the pole surfaces of the magnets 1. For best performance of the coupling it is stated that the transverse dimension b of each magnet 1 should be slightly more than half the radial dimension h, while the air gap 5 between the two coupling members 3, 4 should be smaller than the dimension d of each magnet 1. The magnets 1 are arranged within a sleeve 9 and carried by and cemented to a rim 7, both the sleeve 9 and the rim 7 being of non-magnetic material. The two members 3, 4 may also be arranged to be concentric. Fig. 3 shows an eddy-current coupling wherein the member 4 is replaced by a member comprising a hysteresis disc 11 carrying an eddy-current disc 10. Alternatively, the principles underlying Figs. 2 and 3 can be combined by securing electrically-conductive bodies, Fig: 4 (not shown), in the vicinity of the air gap 5 to the magnets. Specifications 708,127 and 745,911 are referred to.

Title: Improved process for the separation of mineral oil from emulsions
IPC: C10G33/04
Filed: 1929-11-16
Abstract: Mineral oil is separated from emulsions, for example the residues from oil fuel storage tanks, by adding tar or creosote or any fraction thereof or crude tar acids or phenols or cresols or their homologues, agitating the mixture by pumping or other mechanical means or by means of compressed air, and then allowing it to stand until the oil and water have separated.  The water which is then drained off is passed through coke breeze or other filtering material and can then be discharged into a drainage system or the sea.  The process may be accelerated if carried out at raised temperature not exceeding 150 DEG  F.  The tar or creosote used may be obtained by the distillation of coal, shale or wood or derived from coke ovens or blast furnaces.  Reference is made in the Provisional Specification to the use of steam jets for agitating and to the carrying out of the treatment under pressure.ALSO:Mineral oil is separated from emulsions, for example the residues from oil fuel storage tanks, by adding tar or creosote, or any fraction thereof or crude tar acids or phenols or cresols or their homologues, agitating the mixture by pumping or other mechanical means or by means of compressed air, and then allowing it to stand until the oil and water have separated.

Title: Electrical method of and apparatus for producing variable time delay
IPC: H01P9/00
Filed: 1956-11-19
Abstract: 847,609. Electromagnetic delay lines. GENERAL RADIO CO. Nov. 19, 1956 [June 18, 1956], No. 35328/56. Class 40(8). [Also in Group XXV] In order to obtain constant time lag over a wide band of frequencies, portions of the turns of a delay line of the distributed-parameter type are skewed at an angle to the winding axis. Thus, the upper portions of the successive turns of the coil 5, of Fig. 8 lie in planes parallel to the plane P 2  whose normal N makes an angle # with the winding axis 0. It is stated that # should lie between 45 and 65 degrees. The particular configuration shown may be obtained by winding the coil about an insulating former 1 and a block 3, Fig. 5, which is subsequently removed. The upstanding portions of the turns are then bent over by means of a slider or a roller. Automatic winding methods are alternatively used (see Group XXV). The former 1 carries longitudinal conductive strips 13 which are joined to each other at an end. The strips are insulated from the winding by a layer of dielectric 11 to which the winding is glued. The finished coil is bent into circular shape and fitted around the annular flange 31, Fig. 13, of an instrument base 33, a layer of insulant 47 being interposed between the winding and the flange. On the outer side of the coil a further strip 21, insulated from the winding by a layer 46, carries a number of longitudinal conductive strips 23. These and the strips 13 are connected to a common grounding terminal. In order to compensate for a decrease in inductance at the ends of the coil the strips 13, 23 are tapered at their ends. The ends of the winding are connected to terminals on the exterior of the instrument. A further terminal is provided for connection to a rotatable slider which rides upon the upper edge of the coil and provides for variable delay.

Title: Apparatus for time control of the working operations of programmed appliances
IPC: H01H43/10
Filed: 1974-08-12
Abstract: 1484944 Time switches INDUSTRIAS COPRECI SCI 12 Aug 1974 [13 Aug 1973] 35355/74 Heading H1N [Also in Division F2] In a programmed timing apparatus, e.g. for use in a clothes-washing or dish-washing machine, having a pre-arranged sequence of of operations, a ratchet drive mechanism provides means for stopping the drive for programmable time intervals between consecutive operation stages, and comprises an indexable programme-carrying device 30, a reciprocating drive pawl member 49, and a separate ratchet wheel 41 having one or more recesses 10 deeper than other recesses 14, wherein the centre of rotation of the ratchet wheel 41 is caused to be moved relatively to the device 30 by cam means 32, 45 which thereby provide coupling between the indexed position of the programmecarrying device 30 and the position of the centre of rotation of wheel 41. Pinion 34 drives continuously a spiral cam 36 carried by wheel 35, Fig. 2, rotating it clockwise, and thereby drawing back member 49 against the tension of spring 37 until it reaches the position of Fig. 5. The position shown in Fig. 4 then follows, in which member 49 returning forward may impel the programme-carrying drum 30 through one increment of movement in direction 42, provided that pawl 39 has been able to engage one of the ratchet indentations 31. Member 49 is however provided with a second pawl 40 which can engage recesses 10 or 14 in ratchet wheel 41. When pawl 40 sinks into a deep recess 10, it may permit pawl 39 to engage an indentation 31, provided that the centre of wheel 41 is in a position which admits such engagement, as shown in Fig. 4. When pawl 40 engages a shallow recess 14, pawl 39 may be prevented from engagement, and the ratchet wheel 41 alone is then driven forward through one increment without advance of drum 30. Unit time intervals may thus be accumulated by progressive advance of ratchet wheel 41 retained against reverse motion by a detent pawl 45<SP>1</SP>. When subsequently cam follower 45 sinks into a cam recess 32, causing arm 43 to pivot about centre 44, the detent pawl 45<SP>1</SP> strikes a stop 48, thereby releasing wheel 41 to return to its starting orientation, under tension of spring 46.

Abstract: 1,118,435. Gas turbines. BROWN BOVERI & CO. Ltd. Aug.18, 1965 [Aug. 20, 1964], No. 35426/65. Headings F1G and F1T. A free turbine 7 having a nozzle ring divided into three 120 degree segments each of which is supplied through a separate inlet duct by one of three gas generators has an annular conduit for inter-connecting the gas streams produced by the segments so that if one or more of the gas generators is inoperative a gas flow circumferentially of the turbine is set up within the conduit to tend to equalize the temperatures of those parts of the turbine adjacent the conduit. Each inlet duct has outer and inner walls 4, 5, Fig. 3, leading to blades 1 of the nozzle ring mounted between shrouds 2, 3. Shroud 2 defines an annular chamber 12 with wall 4 which is in communication with the inlet ducts through apertures 12a. A further annular chamber 13 formed from sheet metal 14 communicates with the inlet ducts through apertures 13a. When all the gas generators, formed by turbine-compressor sets, are feeding the turbine 7, there is substantially no gas circulation in chambers 12, 13. When one of the gas generators is cut out so that the turbine 7 works with partial admission througH only two of the nozzle segments then a circumferential circulation of gas is set up in the chambers 12, 13 by gas from the operative inlet ducts entering the chambers through apertures 12a, 13a and then flowing into the inoperative inlet duct, which is at a lower pressure, through the corresponding apertures in that duct. The circulating gas heats the components of the inoperative duct so as to reduce thermal stresses. A similar circulation is also set up in an annular chamber 15. In a modification, Fig.4, an annular chamber 17 is provided on the downstream side of the turbine 7, the chamber having apertures 17a communicating with the diffuser space 16 and apertures 17b communicating with atmosphere. In this case the pressure in an inoperative portion of the diffuser is higher than in the operative portions thus causing an air or gas and air flow to be set up in chamber 17 from the inoperative portion and atmosphere to cool the operative portions.

Title: Improvements in or relating to draw-benches
IPC: B21C1/32
Filed: 1920-12-18
Abstract: 173,690. Flather, G. D. Dec. 18, 1920. Drawing .-Relates to draw-benches and consists in means for removing the work when it is released by the die and grippers and depositing it alongside the draw-bench. In the arrangement shown, the draw-carriage 5 is pulled away from the die-head 10 by a chain engaging a counterweighted hook 7. As the carriage moves to the left in Fig. 1, it releases in succession the detents 14 and allows the springs 13 to rotate the spindles 12 to swing the arms 11 across the bench under the work. When the work leaves the head 10, the end falls on the arms 11 and simultaneously it is released automatically by the vice 9, so that the work rests wholly on the arms 11. As the tension on the chain is released, it and the hook fall slightly and a pivoted pawl 23 on one side of the hook passes from the upper to the lower side of the rack 22. The pawl thus engages the rack and moves it and the attached bar 24 to the left. The bar 24 carries a bracket 27 which engages a collar 28 on a bar 20 and moves it to the left, and with it the arms 18 on the spindles 12 which are thus rotated to swing the arms 11 and with them the work to the side of the bench. As the carriage moves on, a cam 32 lifts the rack out of engagement with the pawl against a weighted lever 31 and the movement of the rack ceases. A weight 34 then returns the rack and its connections to their original positions. When the rack is raised clear of the pawl, the weight 8 raises the hook out of engagement with the chain.
