Title: Improvements in apparatus for transferring demountable bodies
IPC: B60P1/64
Filed: 1937-06-18
Abstract: 478,232. Handling removable loadcontainers. MOTOR TERMINALS, Inc. June 18, 1937, No. 17062. Convention date, June 29, 1936. [Class 78 (iv)] In apparatus for transferring load-containers between road and rail vehicles by mechanism mounted on the road vehicle, provision is made for emergency hand operation of the transfer mechanism in the event of failure of the power. The Figure shows one side of the road vehicle in plan; each side being furnished with pivoted roller bridges 30 coupled to the rail vehicle by the pivoted turn-out members 40. Both rail and road vehicles are provided with skidways and the road vehicle is fitted with driven endless chains F to which the load-container is coupled by rigid bars. During normal operation the chains on each side of the vehicle are driven simultaneously by gearing 11, 12, 14, 16 from a cross-shaft 10 which in turn is geared to the motor H. Should the motor fail, a detachable crank 71. carrying a long pinion 73 is inserted through an orifice at the side of the vehicle so that the pinion 73 engages the gear wheel 11, thus operating the chains and turning the motor armature idly during the process. The frame of the vehicle is strengthened at the points which form the bearings for the crank and the latter is provided with a guiding or pilot-piece 74 at its outer end to facilitate the insertion.

Title: Process for the production of foam glass
Inventor: SCHULZ ERNST OTTO
IPC: C03C11/00
Filed: 1964-04-24
Abstract: Foamed glass is formed by first sintering a mixture of glass containing SO3 and active carbon in a steam atmosphere and then foaming in known manner.  The steam atmosphere may be at a pressure of e.g. 200-760 Torr. The steam may be introduced as such or may be produced during the combustion of hydrogen-containing fuels.  The sintering temperature is preferably such that a gas-tight mass is formed; the temperature may then be raised to 800-900 DEG  C. and the material caused to foam.

Title: Improvements in and relating to the distillation of miscella and the deodorisation of the oils and fats contained therein
IPC: C11B1/10
Filed: 1933-06-19
Abstract: <PICT:0404547/III/1> Miscella (a solution of fatty oils in solvents) is distilled to remove solvent and the residual oil deodorised in one operation by utilising the steam and vapours, issuing from the deodorising process maintained under vacuum, in counter-current for the distillation of the miscella.  The miscella may also be indirectly heated while flowing in films over curved heated surfaces. Miscella from a container a is introduced through a preheater c and pipe d into the uppermost of a series of superposed containers g<1>--g<5> of which the containers g<1>, g<2> serve for the distillation of the solvent while the oil is deodorised in the containers g<3>, g<4>, g<5>, maintained under vacuum.  The miscella flows from distributors e<1>--e<5> over the surfaces of drums f<1>--f<5> heated internally by steam or the hot deodorised oil, the oil after each heating stage being collected in containers l<1>--l<5> connected by restricted passages k<1>--k<5> to the containers g<1>--g<5> and forwarded through pipes n<1>--n<4> to the succeeding containers.  Steam is introduced into the lowest container through a pipe p<5> and passes upwardly with the vapours evolved through the containers g being collected from each container by pipes p<4>--p<1> leading to perforated distributors m<4>--m<1> and finally removed through a pipe p to the preheater c.  Difference in pressure is maintained between the vessels g<2> and g<3> by a pump q and a regulator o and a further regulator r may be provided to permit operation as described in Specification 285,380, [Class 32, Distilling &c.].

Winding - machines; driving- arrangements.- To produce a yarn package of t h e shape shown, the yarn-guide is given a uniform traverse and uniform gain, but the traverses increase in speed towards their upper limits and t h e speed of the spindles increases s i m u l taneously. The spindles 2, Fig. 2, are carried in brackets 1<a> on a rail 1 and a r e driven by friction gearings 5, 6. The yarn-guide 40 is carried by an arm projecting from a ring 34, Figs. 4 and 5, loose on the hub 28 of a gear 25 .sliding on a screw 4. A spring arm 29 engages the thread of the screw. Other arms 35, 36, on the ring respectively engage a rod 38, and carry an auxiliary thread-guide and tension disks. The yarn-guide and connected parts are carried by a rail 3 reciprocated by a cam 52 shaped to give an increase in speed as the guide rises towards its upper limit, and to wind fewer turns during the downward movement than the upward movement. To obtain the necessary rise after each reciprocating movement of the guide, a pawl 13 carried by the rail 3 engages a ratchet 15 and operates, through bevelgearing, a shaft 19 carrying a sliding gear 24 meshing with the gear 25. The cam 52 is on a shaft 53 driven from the main shaft 7 through spur gearing.. The shaft 53 also carries a double cam 62 operating: through a lever 58 to slide the shaft carrying the friction gear 6, to cause the spindle speed to vary during each traverse. A lever 22 mounted on a projection on the bracket 1<a> has cam surfaces 11, 21 which are adapted respectively to raise the disk 5 out of gear with the disk 6 and to allow the bevel-wheels driving the shaft 19 to drop out of mesh.
