Title: Improvements in or relating to footwear
IPC: A43B21/24
Filed: 1949-10-18
Abstract: 660,529. Boots and shoes. GREISSINGER, G. Oct. 18, 1949. No. 26668/49. Class 17 (ii). The rear edge f of the flat tread surface of a shoe heel is displaced forwardly of the shoe to a point on the circular arc e which the end of the heel bone F describes about the mid-point of the lower ankle joint S when walking, in order to reduce foot strains. The forward edge of the heel may be displaced forwardly, e.g. in the form of a tongue g to support the shoe in the region of the instep and to avoid reduction of loading surface of heel. The elasticity of the heel may be increased by making it hollow and, if the arch is to be supported, the heel is thickened in that region.

Title: Method of and apparatus for drying substances in vacuo
IPC: F26B5/04
Filed: 1935-09-27
Abstract: In a method of drying products sensitive to heat, as for example, vegetables, berries, flesh and egg albumen, and milk, the products are heated solely by radiated heat in an evacuated chamber and the vapours developed are removed by cooling.  The sources of heat and supports for the products are insulated from the rest of the apparatus.  In the construction shown, the drying chamber is provided on the inside with heat-insulating material 2. The supports 5 for the products and electric heating elements 4 are carried by a frame 30 of insulating material.  Alternatively the supports are insulated from the heating elements by rods, laths or suspension hooks.  The chamber communicates with a vacuum pump 13 by a pipe 12.  A cooling device 10 comprising tubes through which cold water flows is located between the products and the vacuum pump so that moisture given off during drying is condensed and collected in a container 17.  A fan 11 is provided to assist evaporation.  In a modification the cooling means consists of hollow vertical members containing cold water and provided with fins to assist condensation.  In a further modification, the cooling means is arranged as a jacket surrounding one end of the chamber.  When the products are in liquid form they may be introduced into flanged supports through perforated pipes of insulating material which are placed between the heating elements. The drying process is interrupted before all the moisture is driven off and the <PICT:0463080/III/1> <PICT:0463080/III/2> radiated heat is reduced in stages during the latter part of the drying process.

Title: Liquid level control system
IPC: G05D9/12
Filed: 1972-06-09
Abstract: 1386255 Automatic control of liquid level F M C CORP 9 June 1972 [2 July 1971]  26986/72 Heading G3R In a liquid level control system, the level is adjusted by either of two pumps, which are operated alternately in response to signals from electrical level detectors. In the embodiment shown, a rising level of liquid L in tank 10 successively shorts probes 1 and 2 to ground G, only then can logic circuitry, including flip-flop Z2, activate a starter to one of the pumps e.g. 14 to remove liquid from the tank. The level falls until below probe 1, when the pump is turned off and flip-flop Z2 changes state to set the logic circuitry such that the subsequent grounding of both probes 1 and 2 will energize the other pump 16. If one pump is unable the lower the liquid level, and probe 3 is shorted to ground, both motors are energized simultaneously until the liquid level is again below probe 1. The logic circuitry, Fig. 3 (not shown), may also include NAND gates, and oscillators including uni-junction transistors to energize the pump starters via triacs. In an alternative Fig. 1A (not shown) the liquid level is maintained at an upper value by pumping liquid into the tank.

Title: Machine for profiling metal components
IPC: B21H5/02
Filed: 1960-08-05
Abstract: 957,722. Rolling; grooves and ribs. E. GROB. Aug. 5, 1960 [Aug. 5, 1959], No. 27284/60. Heading B3M. In a machine wherein at least one profiling roller 1, Fig. 3, is repeatedly brought into and out of engagement with a blank W to be profiled and wherein the work is fed axially, the roller 1 performs a planetary motion B, Fig. 2, in a plane extending through the axis of the work W the planetary motion B being the resultant of at least two separate motions B 1 , B 2 . The work is fed axially and also indexed by intermittent rotation during the period of disengagement of the roller 1 so that an adjacent groove may be formed on the next working cycle of the roller. Alternatively if the plane of the planetary motion is inclined at a suitable angle to the axis of the workpiece the latter may be continuously rotated resulting in the formation of spaced longitudinal ribs or grooves. The shape of the planetary path B allows profiles to be extended close to a shoulder on the work. The motions B 1 , B 2  are derived through linkages, from a driving shaft 6 which is synchronized with the rotation of the work. The motion B 1  is derived from the reciprocations of a slide 11 carrying the roller 1, the slide being attached through a universally-jointed rod 9 to an eccentric pin 7. The motion B 2  is derived from the oscillations of a slide 16 effected by an eccentric pin 8 through adjustable linkage 12, 13, 14, 15. The slide 11 is supported on the slide 16 and is angularly adjustable on the slide 16 to vary the angle of inclination of the plane of the planetary motion to the axis of the work. Alternatively the rollers 1 may be mounted in the slide 11 so that the spindles are always perpendicular to the work axis the work then rotating continuously and the rollers 1 being in the form of driven worms synchronized to perform one revolution during rotation of the work through the pitch of the grooves. The eccentric pins 7, 8 on the driving shaft 6 are adjustable radially and angularly to vary the form of the motion and the pivot 17 is provided with a screw adjustment for accommodating various diameters of work. In a modification, Fig. 4, a slide 16<SP>1</SP> is pressed towards the work with a predetermined maximum pressure by a closed hydraulic buffer system energized by the driven shaft 6, the motion B 2  being limited by adjustable stops 23 acting on the machine frame.
