Title: Wheel suspension for a vehicle
IPC: B60G3/14
Filed: 1957-02-20
Abstract: 819,223. Vehicle spring suspensions. FRUEHAUF TRAILER CO. Feb. 20, 1957 [March 26, 1956], No. 5800/57. Class 108(2) A vehicle comprises a load-carrying body having a floor structure 14, and a wheel 25 supported upon an axle 26, the axle 26 being supported upon the central portion of a U-shaped lever 16 the arm portions 18, 22 of which extend transversely of the vehicle, the end of one arm portion being pivotally attached to the floor structure adjacent to a side wall of the body, and the end of the other arm portion being resiliently affixed to the floor structure adjacent to the side wall. As shown, the forward arm portion 18 is pivoted upon a pair of adjustable brackets 32 carried by a transverse truss 20 secured to the floor 14. The rear arm portion 22 is secured to an impact plate 34 of a resilient spring 24, e.g. of the pneumatic bellows type. The construction is stated to facilitate the cooling of large size brake drums 46. The bracket 32 (Fig. 6) comprises channel members 56, 58 connected together by bolts 60 passing through elongated slots in the channel member 56 which can therefore be adjusted longitudinally of the vehicle when the bolts 60 are loosened. This adjustment can be effected by means of lock nuts 64 threaded on the ends of a stud 62 welded to the channel member 56 and accommodated within a groove in the channel member 58. The channel member 56 is welded to a cross member 54 of the truss 20, while the lower channel member 58 rigidly supports a pivot tube 68 which carries a resilient bushing 70. An arm 76 welded to the end of the arm 18 rides upon the bushing 70. For purposes' of wheel alignment a retaining bolt 73 can be removed from an aperture in the pivot tube 68 to allow a rigid rod to be positioned within the aperture. This rod is extended transversely across the vehicle through successive pivot tube apertures to align both left and right suspensions. Alternatively this alignment may be performed optically by means of accurately machined bosses 78 on the arms 76 (Fig. 3). In modifications (not shown) the lever 16 may be pivoted directly on a cross member 50 or 52 of the floor 14, and the stub axles 26 may be replaced by axles extending across the full width of the vehicle.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B49/04
Filed: 1927-03-02
Abstract: 267,131. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System Aktiebolag). March 2, 1926, [Convention date]. Drawings to Specification. Refrigerating, absorption machines for.-Continuous-cycle systems operated solely by heat are provided with means for adjusting the supply of heat and simultaneously the supply of cooling- medium to the rectifier, so that with diminished heat supply the possibility of over-cooling of the rectifier is avoided. The arrangement is particularly adapted to machines containing an inert gas and used for cooling domestic refrigerators in which a variable cooling-effect is desired. The heating means may comprise a series of electrical resistances, one of which is used to give a constant supply of heat to the usual liquor pumping pipe and the others for heating the generator proper to a variable degree. A valve in the cooling-water supply to the rectifier, or louvres in a cooling-air conduit for the rectifier, are connected to a handle controlling the heating- means so that they are opened as soon as the minimum heat supply is turned on, and further opened as the supply is increased. The cooling- water supply to the condenser and other parts of the apparatus is also turned on with the heat supply.

Title: Improvements in or relating to train control and/or cab signalling apparatus
IPC: B61L3/12
Filed: 1930-03-17
Abstract: 351,072. Fluid-pressure brakes. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, and HUDD, A. E., 947, West Van Buren Street, Chicago, U.S.A. March 17, 1930, No. 5918/31. Divided on 351,039. [Class 103 (i).] The Specification comprises the train control and cab signalling system described with reference to Figs. 3 to 6 of Specification 351,039. According to the present invention a brake controlling or signalling apparatus on a locomotive is controlled by an armature in a magnetic circuit which effects the movement of a blade of very thin metal over a small slit or opening in a smooth surface to act as a slide valve. As shown in the Figure the armature 3 carries the thin metal blade 63 of phosphor bronze or stainless steel and is pivotally mounted in a brass carrier 56 secured to magnetic collecting plates 4 .. 7 which are adapted to be influenced by track permanent and electromagnets. When only the plates 6, 7 are activated the blade 63 uncovers the slit 92 and opens a vacuum pipe 58 to atmosphere whereby a train-pipe venting valve is operated. The armature 3 is reset by means of an acknowledging key which connects the vacuum system by a pipe 57 to the underside of a spring-pressed plunger 8 which thereupon moves the armature into contact with the collector plates 4, 5. At a clear signal the plates 4, 5 are activated by track electromagnets so that the activation of the plates 6, 7 by the track permanent magnets is not effective to move the armature 3. The collector plates are enclosed in protective casings having as small an air space as possible.

Title: Improvements in or relating to lubricating devices for rotary or other compressors
IPC: F04B39/16
Filed: 1938-02-25
Abstract: 511,950. Lubricators. BOSCH GES., R. (formerly BOSCH AKT.-GES., R.). Feb. 25, 1938, No. 5944. Convention date, Feb. 25, 1937. [Class 12 (iii)] In a lubricating system for rotary and other compressors in which oil contained in the medium delivered under pressure by the compressor 1 is separated in an oil separator 3 from which it is fed back to the compressor through a pipe 10, additional oil being . fed to the compressor to make up for the amount lost from the system by imperfect separation, overflow of'separated oil from the compressor is controlled by a valve 16 which opens when both the level of the oil in the separator has exceeded a predetermined height and when the pressure of the medium begins to fall. The compressed medium enters the separator through a pipe 2 and passes through a filter 4, the air being led off through an opening 8 and the oil collecting in the'sump 7. Additional oil is delivered to the compressor from a pipe 20 by means of a reciprocating slide 23 with an oil pocket 22 and the amount so supplied exceeds that lost by imperfect separation. The valve 16 depends from a bell or float 12 which is pressed downwardly against the action of the rising oil level by a spring 18 and by the air pressure above the bell. If the oil level reaches a predetermined height and the air pressure drops due to the compressor output falling, then the bell rises, and the overflow 17 is opened. In a modified form the bell 32 is housed in a separate vessel 31. Oil flows from the sump to beneath the bell by way of openings 38 in the vessel 31 and helical grooves 39 on the outer surface of the bell.

IPC: B65H37/02
Filed: 1950-03-09
Abstract: 681,024. Coating webs. GOSS PRINTING PRESS CO., Ltd. March 9, 1950. No. 5956/50. Class 140. [Also in Groups XVI, XXVIII and XXIX] Eight paper webs 3-10 for forming into newspapers (see Group XVI) are collated by a roller 2. Seven of these webs, 3-9, each have a longitudinal ribbon of paste or other adhesive applied centrally to thin undersides by nozzles 11-17, which are adjustable and also project compressed air (see Group XXIX). The paste is supplied to each nozzle intermittently so as to produce a ribbon interrupted by paste-free zones arranged to be in alignment when the webs are collared. For this purpose, each nozzle supplies paste for the same length of time with the same intervals, but the suppliers are out of phase, because of the varying distances from the passing points to the collaring point of the webs. Paste is supplied from a reservoir 42. to a pump-mechanism 33 (see Group XXVIII) and thence by separate pipes to the nozzles. Each pipe contains a stopcock closable if fewer than seven webs are to be passed.

Abstract: 1386004 Cracking hydrocarbons SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 9 Feb 1972 [11 Feb 1971 4 March 1971] 6061/72 Heading C5E A naphtha consisting mainly (85% or more) of C 5  and C 6  paraffins, low in aromatics (5% or less) and having a ratio (Y) of iso/normal C 6  hydrocarbons of 2 or more is hydrocracked selectively to remove normal paraffins and improve the octane rating. The feed must contain a proportion (X%) of C 6  paraffins of 25% or more, and 65Y must be equal to or more than 2x+80. The feed may be the product of an isomerization step, and may contain sulphur. Iso-pentanes may be removed from it before cracking, and blended with the product after removal of C 4  and lighter. The catalyst may include a porous zeolite, and may be sulphided. Six process schemes are described: in scheme I a feed is distilled to take off iso-pentanes, the topped naphtha is then isomerized and hydrocracked and again distilled to take off butanes and lighter, the distillate from the first distillation is then combined with the bottoms from the second; scheme II is similar, except that the distillate from the first distillation and bottoms from the second are not combined; in scheme III, the feed is distilled to take off isopentanes, isomerized, distilled to take off pentanes, which are returned to the feed, hydrocracked, combined with the distillate from the first distillation, and again distilled to take off butanes and lighter; in scheme V, the feed is isomerized, distilled to take off isopentanes, distilled again to take off normal pentane, which is returned to the feed, hydrocracked, combined with the distillate from the first distillation and distilled a third time, to take off butanes and lighter; schemes IV and VI are similar to schemes III and V, except that the distillate from the first distillation in each case is not combined with the hydrocracked material, but is redistilled by itself to take off butanes and lighter. Catalysts used are: for hydrocracking, (1) Ni on hydrogen erionite, (2) Pt or hydrogen-erionite, (3) a mixture of catalyst (1) with Ni on hydrogen-zeolite T; (5) Pt on hydrogen-mordenite and (6) Ni on hydrogen-zeolite KSO1, catalyst 2 being used in its reduced form and the other four sulphided; and for isomerizing (4) Pt on hydrogen-mordenite, in the reduced form. Reference is also made to the use of catalysts containing metals of the copper, zinc, chromium and manganese sub-groups for the hydrocracking step.

Title: Vibratory force producing apparatus
IPC: B06B1/16
Filed: 1958-02-26
Abstract: 836,957. Vibratory mechanisms. LANE, J. R. (International Research & Development Corporation). Feb. 26, 1958, No. 6265/58. Class 80 (4). In apparatus for producing unidirectional vibrations of variable magnitude by means of oppositely rotating out-of-balance masses, the masses rotate in parallel bores 12, 14 of a housing 10 and each mass comprises a pair of cylinders 16, 18 or 20, 22 which are rolled around inside the bores by pairs of slotted arms 36, 40 or 38, 42, the arms in a pair normally rotating together but being angularly adjustable relatively to each other to vary the degree of out-of-balance from zero to a maximum. The arms 36, 38 are keyed on respective shafts 32, 24 carrying intermeshing gears 30, 28, while the arms 40, 42 are keyed on respective sleeves 52, 44 which are coaxially mounted on the said shafts and carry intermeshing gears 50, 48. The intergeared shafts 24, 32 are directly driven from a motor 56 by a belt 58, the intergeared sleeves 44, 52 being driven from the shaft 24 through phasechanging gearing 64. The gearing 64, Fig. 6, comprises a gear 66 on the belt-driven shaft 24, a coaxial gear 80 on the sleeve 44, and an interconnecting train of gears 68, 72, 76 mounted between plates 60, 62, the gears 66, 80 thus rotating at the same speed and in the same direction. Adjustment of the phase between the gears 66, 80 is effected by rotating the plates 60, 62 about the axis of shaft 24 by means of a worm and segment drive 84. Such adjustment effects simultaneous angular adjustment between the two rotating arms in each bore 12, 14 and hence varies the magnitude of the unidirectional vibratory force.
