Title: Improvements in or relating to vehicle signalling apparatus
IPC: B60Q1/38
Filed: 1927-08-02
Abstract: 301,521. Waller, P. H. Aug. 2, 1927. Road-traffic signals on vehicles.-In a roadvehicle signalling-apparatus certain electric circuits are so inter-related that the closing of one af the circuits to give a definite signal attracts an automatic cut-out in another circuit, which is thereby prevented from being closed to give a misleading circuit during the time the first circuit is closed. Certain signals may be given in advance by a manual control 12, and then taken over by an automatic control 35 actuated for example, by the steering-mechanism. The following signals may be shown : 1, straight ahead; 2, right turn; 3, right swerve; 4. left turn; 5, left swerve; 6. picking up; 7, slowing down; 8, overtake me; 9, turn about; 10, stop; 11, reverse. The ahead circuit is indicated by 14, 15 armature 16, 17, 1, 18, 19, 20. The manual control 12 has contacts 21. - - 24 for left turn, overtake, turn about, and right turn respectively, and the automatic control 35 has contacts 25 - - 29 for left turn, left swerve, right swerve, right turn, and turn about, respectively. The signals 6, 7, 10, 11 are actuated by some moving part of the vehicle. For giving the manual signal 4 for " left turn," the circuit will be 14, 30, 21, 31, 25, 32, 4, 33, coil 34, 20. The coil 34 attracts the armature 16 and cuts out the ahead signal 1. On actually turning left, the contact member 13 on the steering-wheel 35 first makes contact 26, giving " left swerve," and then makes contact 25, thereby shortcircuiting the path 31, 21, 30 of the manual circuit and allowing the manual control 12 to return to its normal position, but still holding the signal 4 on. The signals 6, 7 for " picking up " and " slowing down " may be given by a part 36 actuated by the speedometer to make contact with a part 37 or 38. The signal 8 for " overtake me " is automatically prevented from appearing by a coil 39 moving an armature 40 if the signal 6 for "picking up " is showing. The " stop " signal 10 may be given by a member 41 actuated by the speedometer, a coil 42 thereupon attracting an armature 43 and preventing the showing of signals 6, 7. A contact 45 closed by a moving part of the vehicle closes the circuit for the "reverse " signal 11. The " stop " and "reverse" signals 10, 11 are on together when reversal is being effected, but the closing of contact 45 operates a cut-out 46<a> for signals 6, 7. The ahead signal 1 is cancelled by the cut-out 16, 34 when any of the signals 2, 4, 9, 10, 11 are given. The manual and automatic controls described in Specification 301,519 and 301,520 may be used.

Title: Improvements in or relating to inorganic oxide gels of spheroidal shape
IPC: B01J21/12
Filed: 1947-07-31
Abstract: <PICT:0645133/III/1> Inorganic oxide gels of generally spheroidal shape are made by making at 35 DEG  to 50 DEG  F. an aqueous sol capable of setting to a hydrogel and extruding the sol into a liquid immiscible therewith, e.g. a mineral oil, and maintained at a temperature higher than that of the sol but below the boiling point of the sol, globules of the sol which are formed in the liquid being caused to remain therein until gelation occurs.  The gelled globules may be removed from the liquid, washed and dried while retaining their globular shape.  In one embodiment, a sol is made by mixing in nozzle 10, two or more reactants from metering pumps 11, 12 and coolers 31, 32.  The sol is extruded into a column of oil heated by a steam coil 16, and the spheroidal particles formed set as they descend the oil column and pass into water at the bottom of the vessel 15 from which they are removed in a current of water by pipe 19.  By using a liquid of higher specific gravity than the sol, globules are formed with upward movement of the sol through the liquid. In another embodiment, the sol, which may be prepared batchwise and may be heated prior to extrusion, may be extruded into the p  liquid by continuously flowing it into a cylindrical vessel having perforated side walls and rotated rapidly (about a vertical axis) within the immiscible liquid.  Specification 576,058 is referred to.  The Specification as open to inspection under Sect. 91 comprises also forming aqueous sols at temperatures above 50 DEG  F., e.g. 70 DEG  and 75 DEG  F.  This subject-matter does not appear in the Specification as accepted.

Title: Pulp molding apparatus
IPC: D21J7/00
Filed: 1958-07-01
Abstract: 853,431. Moulding pulp articles. KEYES FIBRE CO. July 1, 1958 [July 11, 1957], No. 21052/58. Class 87(2). Pulp is drawn by suction on to perforated male dies 36, Fig. 1, passed through pulp slurry in a tank T, to form shapes which are transferred to perforated female dies 68 and thence to perforated male forms 128 on which they are conveyed through a drying zone. The dies 36 are pivotally mounted on the arms 20 of a rotating turret comprising a motor driven shaft 10, and each die is caused to move through the slurry in a straight horizontal path by the engagement with a cam track 52 of a roller carried by an arm 44, in the manner described in Specification 777,395. Similarly the transfer dies 68 are pivotally mounted on arms 58 extending radially from a pair of aligned rotatable shafts 54, and the movement of each die 68 is controlled by the engagement with a cam track 80 of a roller 78 carried by an arm 70. The cam mechanisms cause the dies 36, 68 to move parallel to one another at the transfer position when the suction applied to the die 36 through conduit 86 is replaced by fluid pressure applied through conduit 84. The forms 128 are carried by an endless chain conveyer 116 through a drying oven D, Fig. 4, and the dried articles are received by a shoot 138. During the transfer of an article from a die 68 to a form 128 fluid pressure is applied to the die, and suction is applied to the form via a suction pipe 98 revolving with the driving pinions 88 of the conveyer. Each suction pipe 98 has a nozzle with a hemi-spherical end adapted to engage a corresponding surface of a tube 124 communicating with the interior of the form 128. The apparatus is adapted to make resilient uncompacted articles, but it may be modified by providing the transfer dies with spring means for applying pressure for partially compacting and removing water from the article.

IPC: F16K17/14
Filed: 1966-05-13
Abstract: 1,143,291. Nuclear power plant. COMMISSARIAT A L'ENERGIE ATOMIQUE. 13 May, 1966 [19 May, 1965], No. 21265/66. Heading G6C. [Also in Division H1] In a thermoelectric generator adapted to be mounted in a nuclear reactor, the thermoelements 1a, 2a consist of a high proportion (80 -100%) of a fissionable or fertile material such as the oxide, carbide, monosulphide, oxyselenide, nitride or oxysulphide of uranium with a small amount (about 1%) of a doping additive such as carbon, bismuth or tellurium. The elements, which are of alternate N and P type, are in powder form and are strongly compressed by clamping them between end terminals 7a, 8a. They are housed in a stainless steel tube 10a with an electrically insulating lining 11a and are interposed by insulating rings and discs 3a, 4a so shaped that the successive thermo-junctions 5a, 6a are located at the centre and the periphery of the tube, respectively, to provide a zig-zag current path through the generator. The tube 10a is mounted in a reactor channel 25 through which cooling fluid is circulated, and the reactor fuel may consist entirely of such generators, so that the energy of the reactor is converted directly into electricity, or of both generators and conventional nuclear fuel cartridges so that the output of the generators can be employed for monitoring the reactor. The Specification gives numerical values of the thermoelectric power, resistivity, thermal conductivity and quality factor of several exemplary thermoelements. In an alternative embodiment (Figure 1, not shown) the thermoelements are of normal non-fissionable material and are formed as rings mounted on an inner tube (12) which may be filled with polonium. The disintegration of the polonium provides heat for the hot junctions of the generator.

Filed: 1925-08-25
Abstract: 239,205. Soc. Anon. des Forges et Chantiers de la MediterranÚe. Sept. 1, 1924, [Convention date]. Tension arrangements. - The endless chain-tracks of a tractor are tensioned from within the tractor body by means including a spring which yields under a predetermined stress and so gives an indication that the track is sufficiently tensioned. The track passes over guide rollers A the axle B of which is adjusted in guides C by a screwed rod F moved axially by means of a rotatable nut H and worm gearing I. The worm I is rotated by a hand lever J and ratchet and pawl mechanism, and the hand lever is provided with a hinged arm K forced outwards by a spring L so that a pin M on the lever is shielded by the arm. When the track has been sufficientlv tensioned the force needed to move the hand lever causes the spring L to yield and thus allow the pin M to protrude and catch the hand of the operator. The rod F bears through spring washers e against a socket E carrying the axle B.
