Title: Electrically-heated beverage brewer
IPC: A47J31/047
Filed: 1948-03-05
Abstract: 638,611. Electric coffee percolators. RAMSEY, A. R. J. (Cory Corporation). March 5, 1948, No. 6937. [Class 39(iii)] [Also in Group XXXVII] A beverage brewer, e.g. a coffee percolator, of the vacuum type comprises two vessels, one of which is 12, a high heat and a low heat electric element 40 and 46 respectively and a thermal switch heated by both elements 40 and 46 and adapted to disconnect the high element 40 and to switch into circuit the low element 46 upon being heated. The vessel 12 is below the other vessel, a pipe depending from the upper one which contains a filter and the coffee. The vessel 12 is in four parts, the high heat element 40 being enclosed in an annular groove in the lower face of a wall 32 of one of the parts 28. In the middle of this lower face 32 and contacting it is fixed the flat insulated heating element 46, which is carried on a plate 52 below which is mounted the thermal switch which is bimetallically operated (see Group XXXVII). This switch is constructed so that at first only the high heat element 40 is operative to drive the liquid into the upper vessel. As the temperature rises, first the element 46 is brought in in parallel with the element 40, then the element 40 is de-energized. At this stage the coffee returns to the vessel 12 and is there kept warm by the element 46. Although the element 46 is of lower wattage than the element 40, it is nearer the bimetal, and so it maintains the switch in this later condition indefinitely. If the apparatus is disconnected from the source of electricity, the switch will eventually re-set itself to repeat the cycle of operations at a future date.

Title: Improvements relating to machines for manufacturing envelopes, paper bags and the like
IPC: B65H9/14
Filed: 1926-03-15
Abstract: 270,860. Hugo, T. March 15, 1926. Sheet-registering devices; sheet-carriers.-In a machine for making envelopes, paper bags, cardboard boxes, &c. in which the blanks are received and carried forward by pairs of conveyer bands, traveling in the same direction, to the folding box or other working position, the feeding movement of the blanks, shortly before reaching these positions is arrested, or its velocity diminished, by decreasing the friction between the pairs of conveyer bands. The blanks are started slowly, then conveyed at the maximum speed, and finally this speed is reduced before the blanks engage the arresting devices provided at the working position. A blank is fed by contacting conveyers 1, 2, Fig. 1, which are driven intermittently by a toothed sector 17 adapted to engage a toothed wheel 19 loose on the shaft 15 of the drum 11 of the lower conveyer, but connected to it by a ratchet and pawl device which ensures that the conveyer is moved in one direction only. A cam bar 14 operated by a lever system 16 displaces the upper conveyer vertically and thereby alters the friction between the conveyers. In another form, the conveyers 1, 2, Fig. 5, run continuously, their action on the blank being varied by moving them awafrom or toward each other by a bar 14 provided with two cam surfaces and actuated regularly by lever system 16. In other forms, eccentrics mounted on the conveyer shafts engage each other to separate and draw together the conveyers and the drums of the conveyers may themselves be eccentrically mounted on their shafts and be adjusted for different thicknesses of paper by suitable hand wheels The blanks may travel on parallel pairs of bands which drive printing or other rollers adapted to operate on the part of the blank between the conveyers, the rollers travelling at the same speed and in the same direction as the conveyers.

A disc coil winding in which each disc coil 19, 20, 22, 23 (Fig. 1) comprises two (or more) insulated conductive strands A, B, forming radially interleaved turns at least one strand in each coil being severed at least once (e.g. at B0/B6, B6/B12) to provide radially separate portions having inner and outer radially spaced ends. The relative positions of two parallel circuits through the coils are transposed from one pancake coil to the next. Transposition of the position of the A and B circuits between coils 20 and 22 may be arranged as in Fig. 1 or Fig. 4 a detailed description of the method of construction and interconnection being given (Figs. 2 and 5, not shown). In a preferred arrangement the A and B conductors are severed alternately in alternate coils to provide radially separate portions and this arrangement may be used in a double interleaved construction as shown diagrammatically in Fig. 7. Four conductive strands LA1, LB1, LC1, LD1 may be used as illustrated in Fig. 9 which shows a single interleaved arrangement in which full transposition of the strands needs four coils. The procedure for winding the coils, and cutting, and interconnecting the conductors to give only one brazed joint per coil is described (Figs. 10- 14, not shown). The methods and constructions involved in providing tappings are also described in detail (Figs. 15-21, not shown). Fig. 26 shows an arrangement having three conductive strands per coil, only two being interleaved at any section of a coil, full transposition of the conductive strands occurring over three coils. A comparable arrangement with different interconnections is also described (Figs. 27 and 28, not shown) as are other threeconductor arrangements (Figs. 31-33, not shown) and two four-conductor arrangements (Figs. 29 and 30 and 34 and 35, not shown).
