Filed: 1931-02-10
Abstract: 366,286. Automatic feed weighers. SOUTHALL & SMITH, Ltd. and PARTRIDGE, R. B., Villa Street Works, Hockley, Birmingham. Feb. 10, 1931, No. 4129. [Class 143.] In an automatic weighing machine, the discharge shutter, closing the base of the weigh pan is pivoted above the shutter and is acted upon by a spring device in such a manner as to cause the shutter, when opened, to strike one side of the pan and so shake down any adherent powder. As shown in Fig. 1, the discharge shutter b carried on a pivot d is connected to a spring g and after being displaced by an operating lever f, Fig. 2, is swung open by the spring so as to bring one edge of the shutter into contact with the weigh pan and dislodge any adhering material. Preferably the weigh pan is provided with a loose lining h adapted to be struck by projections i on the shutter. When the weighing is effected in two stages by delivering the material in the pan a to a second pan j, the lower end of the pan a is situated well within the second pan thereby minimizing the production of dust clouds.

Title: Production of domestic heating gas
Filed: 1964-01-31
Abstract: Domestic heating gas is produced in a single conversion step by the reaction of naphtha and steam in the presence of a steam reforming catalyst in a conversion zone from which the outlet pressure is between 300 and 1200 p.s.i.g., wherein the space velocity of the naphtha supplied to the zone is between 400 and 2150 volumes of naphtha per hour per volume of catalyst (naphtha expressed as methane equivalent at standard conditions), the steam-carbon ratio is at least 1.55 plus 0.00113 times the space velocity, i.e. at least 2.0, but at most 4.0, and wherein the inlet end, at least, of the zone is externally heated to obtain a temperature at a point in the zone of at least 1300 DEG  F. Preferably the naphtha is preheated to 700 DEG to 1100 DEG  F., and the conversion products are cooled at the outlet end of the conversion zone, to impose an artificial hill-shaped temperature profile on the gas in the conversion zone.  "Naphtha" includes aromatic, paraffin and naphthenic hydrocarbons of M.W. 70-170 boiling up to 550 DEG  F. and having a sulphur content less than 10 p.p.m. Preferred catalysts contain 4-40% by weight elemental or combined nickel, at least 0.5% alkali or alkaline earth metal compound and a porous refractory.  The product contains 45-50% H2, 5% CO, 32-33% CH4 and 13-17% inerts (CO2, N2, A) (all molar percentages).

Title: Timepiece movement, with an automatic winding mechanism comprising a lockable oscillating weight
IPC: G04B9/02
Filed: 1952-02-20
Abstract: 709,774. Watches. FELSA AKT.-GES. Feb. 20, 1952 [March 14, 1951], No. 4471/52. Class 139 A timepiece movement with an automatic winding mechanism comprising an oscillating weight is characterized in that it includes a differential gear operatively connected between the barrel and the barrel arbor for driving a member by the barrel in one direction of rotation and by the barrel arbor in the other direction, a locking device for the oscillating weight, and an actuating member moving the locking device into engagement with the oscillating weight upon rotation of the driven member in one direction and moving the locking device away from engagement with the oscillating weight upon opposite rotation of the driven member to prevent overwinding. A lever 28, Fig. 1, pivoted on a pin 29 is connected by a pin and slot 26, 27 to the end 23 of a spring 22 the other end 24 of which is attached to the collar 21 of a lever 20 mounted on a pin 19. The end of the lever 20 lies adjacent a projection 15 on a cam disc 14 and the end of the spring 22 abuts a pin 30 on the pin 29. The two parts 23, 24 of the spring 22 are interconnected by a curved part 25. The disc 14 is fixed to a sleeve 10 rotatable round a pin 11. Rigid with the sleeve 10, Fig. 2, is a sun wheel 12 and rotatable round the sleeve 10 is a sun wheel 9 rigid with a drive wheel 8 which meshes with pinion 3 fixed to the barrel arbor 4. Two intermeshing planet pinions 13 one of which engages the sun, wheel 9 and the other the sun wheel 12 are rotatably carried by a drive wheel 5 which meshes with a pinion 2 fixed to the barrel 1. The arrangement is such that if the weight 18 is driving the barrel arbor 4 through means not shown the disc 14 is rotated anti-clockwise and if the barrel 1 is being rotated by the mainspring the disc 14 is rotated clockwise. The lever 28, Fig. 1, has two notches 32, 33 which may be brought into engagement with either of two pins 35, 34 on the weight 18 to lock it. In operation, with the weight 18 locked in the position shown in Fig. 1 the disc 14 is rotated clockwise so that its projection 15 moves the lever 20 anti-clockwise so flexing the spring 22 until it snaps away from the pin 30 and moves the lever 28 clockwise to free the weight 18. The mainspring is then wound by the weight and the disc 14 is rotated anti-clockwise so that its projection 15 moves the lever 20 clockwise to again flex the spring 22 until it snaps from the pin 30 and moves the lever 28 anticlockwise against a stop, not shown, so that either of the pins 34, 35 on the weight may be engaged by either of the notches 33, 32 to again lock the weight 18. In another arrangement, Fig 4, not shown, the lever 28 carries one pin which may engage in any of a plurality of notches in the weight. Specification 709,775 is referred to.

Title: Automatic alarm device
IPC: H04M1/274
Filed: 1960-03-09
Abstract: 993,211. Automatic exchange systems. A. E. HEDGES. June 9, 1961 [March 9, 1960], No. 4517/60. Addition to 917,138. Heading H4K. The automatic alarm device described in the parent Specification is modified so that, when operation of the device is initiated, a digit is dialled once or a predetermined number of times, whereafter the recording on the gramophone record disc is traversed a number of times by the pick-up means without the digit being redialled. Thus a number, e.g. 999, is dialled once only, even though traversing of the record disc is repeated a number of times. A shaft G (Fig. 1), in use driven by reduction gearing from a motor K, is provided with a radially projecting pin 11 which can engage with a slot 12 in the boss 10 of a cam wheel H (Figs. 2, 3). A roller 24 in the " ready " condition engages in an indentation 23. on the periphery of a wheel 21 fixed to a second wheel 20. Wheel 20, in use, is driven by motor K through a projection 22 on a wheel AB. On operation of an alarm switch, wheel 20 is advanced and roller 24 is disengaged from indentation 23. Linkage 25, 40 raises roller 43, thus allowing telephone rest AG to rise. Pin 11 on shaft G is in register with slot 12 in boss 10 and the cam wheel H is caused to bring projections HI (Fig. 2) successively into engagement with roller J6 in the manner described in the parent Specification, thereby to dial 999. After cam wheel H has made part of a revolution, projections H1 engage the sloping part of a plate member 31 (Fig. 3) and the cam wheel slowly climbs until pin 11 is disengaged from slot 12. The cam wheel H then ceases to rotate, thereby preventing further dialling of digits. A lever 70 (Fig. 5) secured by pivot 71 to the frame AZ serves to hold gramophone needle G2 away from gramophone disc D during dialling. One end 72 of lever 70 rests on the upper surface of cam wheel H while an extension 73 at the other end engages the underside of a pin 74 at the lower end of a link Q which couples a lever P to a return member U. In the " ready " condition lever 70 is as shown in Fig. 5 and holds needle G2 away from disc D. After 999 has been dialled, cam wheel H is moved upwardly by plate 31 and causes lever 70 to be pivoted, whereby extension 73 is moved from pin 74. Needle G2 drops on to the disc D. A cam face F1 (Figs. 1, 4) intermittently raises return member U to return needle G2 to the beginning of the record disc, whereby traversing of the disc D is repeated a number of times. Eventually wheel 20 almost completes one revolution whereupon a trip lever operates the dolly of a switch 50 to switch off motor K. Almost simultaneously, roller 24 re-enters indentation 23 and roller 43 is lowered on to the telephone rest AG. The device may be restarted by a further alarm whereupon at the end of the sequence of operations the trip lever moves the dolly in the opposite direction to switch off the motor K. To this end the alarm switch and the dolly switch are so wired that either switch can be used to change the condition of the device. Specification 917,139 also is referred to.
