Title: Improved freight handling vehicle
IPC: B60P1/64
Filed: 1936-09-01
Abstract: 476,705. Handling removable loadcontainers. FITCH, B. F. Sept. 1, 1936, No. 23949. Convention date, Sept. 9, 1935. [Class 78 (iv)] Means for handling transferable load-containers comprises a power-driven highway tractor, a trailer coupled thereto, guideways on the trailer for supporting the load container, mechanism for moving the container along the guideways and an electric motor on the trailer for actuating this mechanism ; the motor being actuated by a suitable source of power which may be an electric generator mounted on the tractor and coupled with the propelling motor. Fig. 3 shows a road vehicle comprising a tractor T and trailer T<1> connected by a pair of bridging- members B with a railway truck R from which the container C is to be transferred by sliding or skidding. A pair of endless chains 30, Fig. 11, are mounted on opposite sides of the electric motor M and reduction gear 53 and are driven in unison by the common crossshaft 54 through double-reduction spur gear 56, 57, 60, 67, and chain drive 69 leading to the driving-sprocket 39 through the shaft 34. The chains extend from the front of the trailer to the outer end of the pivoted bridges, the shaft 40 in each case forming the pivot between the trailer and the bridge and the shaft 34 the pivot round which the hooking-means swivel. By clamping an idle sprocket 102 against rotation by means of hand-operated screwmechanism 100, the bridge may be maintained in any selected angular position against the action of gravity. Each chain carries a pair of perforated plates 82, Fig. 14, into which is fitted a block 84, Fig. 15, adapted to be fixed in position by the member 86, Fig. 16. The block 84 carries a pivoted rod 80 connected at its other end to the movable container. The outer end of the bridge member carries a member 44 adapted to be engaged with turnout' members 45 mounted on vertical pivots on the railway truck. To couple the bridge to the truck, a rod 48 is turned so that its cranked ends lie in a horizontal position so that they pass through the elongated slots 47 when the members 45 are turned to engage the bearing members 46. Release of the rod allows the cranked ends to fall and retain the members 45 in the engaged position. The trailer, bridges, and truck all carry guideways of the same gauge adapted to receive rails fixed to the base of the container. In the initial stage of the transfer the truck, bridges and trailer are in the position shown in Fig. 3, with the bridges sloping downward, at an intermediate stage with the fore end of the container half-way across the bridge their upper surfaces form a straight line sloping upwards from right to left while in the final position with the load on the trailer all three surfaces are horizontal and at the same level. Specifications 460,826, 471,327, and 474,362 are referred to.

A press slide 22 is reciprocated by mechanism comprising a shaft 3, driven at constant speed by an electric motor, and an intermediate shaft 8 driven at a non-uniform velocity from shaft 3 and carrying an eccentric sheave 9 on which is rotatably mounted a member 17 which is coupled to the slide 22 by a connecting-rod 15. A gear-wheel 30 on shaft 3 meshes a gear-wheel 2 which carries an eccentric pin 4. On arm 7 secured to intermediate shaft 8 is coupled to pin 4 by means of a link 5. A link 11 couples member 17 to a stationary support member 13. The mechanism reduces the idle time during which no processing operation is performed.

Abstract: 1,009,035. Rolling. BOCHUMER VEREIN FUR GUSSSTAHLFABRIKATION A.G. June 22, 1962 [July 1, 1961], No. 24105/62. Heading B3M. [Also in Division G3] A continuous finishing rolling mill includes feedback control means for individually controlling the passes of several stands, and a regulator for at least one of the stands for gradually decreasing the roll pass at a rate which compensates for the increase in gauge of the rolled product as its temperature falls. A strip of initial gauge So and final gauge S passes stands I-VII and has its thickness measurements fed from gauges 9 and 10 to a mixer which rescales the information and feeds it to a computer 7 to control the passes of stands III to VI. The passes of stands I and VII are held constant at a value determined at the start of rolling. In addition, a regulator 11 is fed information resulting from prior experience with different lengths and sizes of strip, thus causing stand II to reduce its pass gradually to counterbalance the tendency of the strip to increase in gauge as its temperature progressively decreases. The regulator 11 may be associated with stands I and III, or II and IV. The control equipment 2 associated with the stands IV to VI comprises a device 5, such as a load cell, for measuring pressure, a controller 4, and adjusting means 6, such as a screwdown.

The chamber is not necessarily of rectangular form. Reference has been directed by the Comptroller to Specification 15876/14.
Patent GB-700620-A (GB)
Title: Improvements in and relating to the manufacture of varnish oils
IPC: C09F7/00
Filed: 1950-10-03
Abstract: Varnish oils are manufactured by incorporating with raw linseed oil, cyclopentadiene or a substance yielding the same under the conditions, and heating the mixture under reflux condenser conditions at atmospheric pressure to a temperature not greater than 450 DEG F. After the free cyclopentadiene has distilled over the temperature may be raised to 600 DEG F. in the same apparatus, or in a vacuum pan, or in a closed pan with carbon dioxide or like inert atmosphere, or in an open pan under atmospheric pressure or lower pressure, to increase the viscosity of the varnish oil.  The raw linseed oil starting material may contain a proportion of other oils compatible therewith up to less than 50 per cent. by weight of the total; dehydroxylated castor oil, oiticica oil, tung oil, stillingia oil, tobacco-seed oil, fish oil, soya bean oil, niger seed oil and isano oil are specified. Dicyclopentadien may be used.  The reaction may be effected in the presence of a peroxide catalyst such as benzoyl peroxide, or a percentage of oil having a peroxide content, e.g. a blown oil, or both.  The reaction may also be effected in the presence of non-reactive solvents such as white spirit or a paraffin oil which is removed together with unreacted diene at the completion of the reaction.  The varnish oil products are additive compounds of the drying oil and cyclopentadiene, particularly a linseed oil cyclopentadiene complex containing between 5 and 20 per cent. by weight of cyclopentadiene.  Specification 700,621 is referred to.

A sealing ring 7 is provided within the female member to seal around the forward end of the extension 5. When the two members 1, 2 are inserted into one another the bevelled surface of the extension 9 spreads the fingers 13 which then contact the forward edge of the jacket 26 pushing back the retaining sleeve 18 until the bosses 14 enter the groove 10 whereupon the spring 19 returns the sleeve 18 to the position shown in Fig. 1, the jacket 26 retaining the bosses 14 in position in the groove 10. Release of the members 1, 2 is effected by pulling them apart after manual movement of the sleeve 18 against the action of the spring 19. The coupling may also be used for rotatable shafts in which case the groove 10 extends only over small portions of the periphery of the extension 5 corresponding to the width of the bosses 14 thus preventing relative rotation of the members 1, 2.
