Title: Improvements in or connected with coin freed mechanism for meters
IPC: G07F15/04
Filed: 1933-03-17
Abstract: 416,672. Prepayment mechanism for meters. GLOVER & CO., Ltd., T., and WILSON, J. S., Angel Road, Edmonton, London. March 17, 1933, No. 8170. [Class 27.] In meter prepayment mechanism for use with either of two coins of different size so that delivery is proportional to the value of the coin used, and having two quantity wheels engageable by a rotatable coin pocket, quantity mechanism is set forward the same amount for either coin, and is set back by the meter mechanism either directly, or through a delay action gearing, according to which coin is used. A quantity wheel 1 is coupled directly to the coin side 4 of the quantity mechanism, the meter side 10 of which is driven through a worm wheel 11 from a worm 12 loose on a shaft 13, and normally engaged by a sliding clutch member 14 rotatable with the shaft 13, which is driven by the meter mechanism. Clutch member 14 is also engageable with a worm 16 geared through a shaft 18, Fig. 5, with a sun wheel 21 of a differential gear, the other sun wheel 22 of which is driven from the quantity wheel 2 through gear wheels 31, Fig. 1, 26, Fig. 5, worm 24 and worm wheel 23. A pin (not shown) on the planet carrier 40 normally engages a pin 38, Fig. 6, to hold a spring catch 37 out of engagement with a spring actuated lever 36, so that it holds clutch member 14 in engagement with worm 12 by means of a sliding yoke 34. When the larger coin is inserted, quantity wheel 1 is engaged and rotated so that the quantity mechanism is set forward, and subsequently set back by the meter mechanism through shaft 13, clutch member 14, worm 12, and wheel 11. When the smaller coin is used, both quantity wheels 1, 2 are rotated together, wheel 1 setting forward the quantity mechanism as before, whilst wheel 2 rotates a ratchet wheel 25 fast with wheel 26, so that lever 36 is tilted by means of pawl and lever mechanism (not shown) to engage clutch member 14 with worm 16, and simultaneously rotates planet carrier 40 through sun wheel 22 and gears 23, 24, 26 and 33, so that catch 37 is released to hold lever 36 in its tilted position. Initial rotation of shaft 13 by the meter rotates sun wheel 21 until the planet carrier 40 returns into engagement with pin 38, whereupon catch 37 releases lever 36 which returns to its normal position in which clutch member 14 engages worm 12. The quantity mechanism is then set back as in the case of the larger coin.

Title: Improvements in methods for the manufacture of coffee concentrates
IPC: A23F5/26
Filed: 1958-03-14
Abstract: 879,317. Coffee concentrates. VITAGEN CORPORATION. March 14, 1958 [March 26, 1957], No. 8344/58. Class 129. An aqueous coffee concentrate is made by contacting roast ground coffee with hot water in an atmosphere substantially devoid of oxygen and containing components resulting from the burning of a hydrocarbon fuel with insufficient air and including carbon dioxide, carbon monoxide and some unsaturates. The unsaturates are highly active gaseous products probably resulting from the interaction of hydrogen, carbon dioxide, carbon monoxide and unsaturated hydrocarbons in the presence of water vapour. The gas used throughout is that produced by the method described in Specification 879,318 and the steps are as shown in Fig. 1. The roasted coffee beans are ground, not too finely in an atmosphere of the gas and then stored, e.g. in sealed moisture-proof bags for three to five days while carbon dioxide is evolved. Roasting may also have been carried out in an atmosphere of the gas. The ground coffee is then vacuumized and gassed, step 12, in a sealed container where a vacuum of 25 to 29 ins. mercury is applied after which the gas is supplied. The grounds are then extracted, step 13, with hot water at 190‹ to 200‹ F. through which the gas has been bubbled. In step 14, after the concentrate has been removed from the grounds, hot water is passed therethrough to remove any concentrate remaining and the hot water is returned for use in step 13. The extract from step 13 can be packed in cans, the filling and sealing preferably being carried out in an atmosphere of the gas. Alternatively, the concentrate may be spray dried, step 16, also in an atmosphere of the gas. Steps 12, 13 may be carried out by the apparatus, shown in Fig. 2, which consists of a vertical container 21 with a removable cover 22. A suitable screen is mounted in the lower end of container 21 and additional screens and a filter membrane at the upper end. Hot water is supplied through pipe 23 beneath the lower screen and the whole container can be vibrated by device 24, the gas being introduced through pipe 25. Pipe 26 may connect the container to a vacuum pump or the like and pipe 27 may discharge the concentrate. Gas may be bled off through pipe 29 and pipe 30 serves as a drain. The container 21 may have a hot water jacket.

Title: Improvements in or relating to the heating of dielectric materials
IPC: B29C65/32
Filed: 1944-05-05
Abstract: 598,587. Dielectric heating. STANDARD TELEPHONES & CABLES, Ltd., and MADDOCK, A. J. May 5, 1944, No. 8526. [Class 39 (iii)] In the heating of a dielectric body by high frequency electric fields, the electrodes applied to the body are sufficiently heated by the passage of the high frequency current to avoid deleterious cooling of the dielectric body. Thus the electrode materials may be of high resistivity or of a magnetic permeability greater than unit, such as zinc, nickel, brass, carbon molybdenum, iron or steel. Alternatively, the electrodes may be backed by a dielectric material which is heated by stray high frequency fields. Such backings can be of asbestos-cement, mica-glass, thermosetting resin or wood. Both methods may be used in combination. Specifications 575,292 and 578,757 are referred to.

Soldering and brazing.-In a machine for soldering or brazing ornamental heads on nails, metal buttons, military ornaments, and like articles, the articles are carried by one or more disks intermittently rotated over a stationary gapped table, and the solder &c. is fused by a blowpipe, the gasinlet tap of which is operated automatically. The nail heads d are carried in an apertured disk c with their ends resting on the table a, and the stems f pass through guides in the disk e. These disks are mounted on a spindle b which is intermittently rotated through a star-wheel h by a projection j on a shaft k operated by worm gear l from a belt-driven or other pulley. The shaft b also carries a second star-wheel i which operates a spring-retracted lever m for closing the plug of a gas-cock n for controlling the supply of gas to a blowpipe nozzle o. The soldering-material is applied either before or after the heads have been inserted in the machine and at the required location, and the disks rotated to a position opposite the nozzle o, where the solder is melted while the work is stationary. During the next motion of the disks, the supply of gas is cut off, the air which is admitted from a fan or compressor to the nozzle through the pipe p cooling the solder. The gas is then re-admitted and is ignited by a pilot frame. The finished articles are discharged through a gap in the table.
