Each element 16 is constructed oi two plates joined at their edges, openings 18 being left for the inlet and outlet of the air or water. Hooks 19 are provided on one edge 17 of each element and adapted to engage holes 20 in angle-irons 21 secured around the flue 22; alternatively, the elements may have holed lugs engaging pintles on the angle-irons. Baffles 24, 25 regulate the passage of the hot gases between the elements, the flue 22 acting as a bye-pass. Surrounding the casing 28 of the heater at the exit of the heated air or water is a hollow ring 29 connected with a fan or pump for drawing the air or water through the elements. A gastight joint at the mouths of the elements comprises a bolt 31, Fig. 6, secured between the elements, against which bears packing 33 retained by a holed filling piece 34. Bolts 36 passing through distance rings 32 arranged within each element and through the holes in the filling pieces 34 clamp the whole together. The casing 28 of the heater is readily removable and may be in the form of doors or panels. The pintles on which the elements hinge may be adjustable and the elements may be flat or curved and mav project radially, tangentially or otherwise around the flue 22. Steam jets may be provided for clearing the hot gas spaces. When water is to be heated, the elements may be constructed from tubes for a straight or circuitous flow therethrough.

Title: Improvements in slotted shutters for photographic cameras
IPC: G03B9/08
Filed: 1935-10-10
Abstract: 454,740. Photographic shutters. KAFTANSKI, F., 173, Kurf³rstendamm, Berlin. Oet. 10, 1935, No. 27940. [Class 98 (i)] A shutter has a slotted slide and a cover slide adjustably connected together, and the former is also connected at opposite sides to elastic metal bands, which coil or uncoil as the slides are moved. The slide b with its slot c is loaded for movement by a spring d connected to the casing, and is also connected to the cover slide l by a spring d<1>. Metal blinds e are fastened to fixed pins e<1> and to the slide b. A double-armed spring-controlled pawl f is pivoted on the slide b, one arm projecting through the slot c and the other engaging a trip hook g. When the shutter is wound up by moving the slides to the right, the cover slide contacts first with an adjustable slide n, the slotted slide b moving further until a pin i engages an inclined surface h of the trip hook g and the pawl f is sprung into one of a series of slots on the cover slide l. This action determines the width of the effective slot for the exposure. After the exposure, a cam rail o causes the pawl to be disengaged from the cover slide and a stop k rocks the trip hook back into engagement. The metal blinds coil and uncoil and prevent passage of light except through the exposure slot.

A device which may be used both for lifesaving and as an aid to swimming comprises a floatable sleeve made of a flexible material and having a streamlined cross-section, the inner longitudinal edge of the sleeve being thick and rounded and provided with a hole for the passage of the thumb of the wearer whilst the outer longitudinal edge is thin and adapted to act as a fin, the said sleeve being adapted to enclose at least a part of the hand and the forearm of the wearer. The sleeve shown in Fig. 1 comprises a sheet of cellular rubber material 1 shaped as shown in Fig. 2 and of varying thickness as illustrated in Fig. 3 folded along the line a, b, and glued or otherwise connected along the edges 2, 3. A hole 6 is provided for the wearers' thumb whilst the flexibility of the sleeve is increased by the provision of transverse slots 14 cut into the inner surface of the sheet. The rear triangular extensions 5 may extend further to the rear as shown in chain-dot lines at 5a. Holes 10 are provided for the escape of any water which may have entered the sleeve. In a modification the sleeve, instead of being formed from a single sheet, comprises upper and lower walls which are joined together along both longitudinal edges. In a further modification the sleeve is formed by folding material of a shape similar to that shown in Fig. 2 the material comprising a double-walled structure filled with kapok, cork or with air or another fluid. Fig. 10 shows a sleeve which is open at both ends and is formed of a single sheet of material joined together after folding by pressbuttons 27. In vet another embodiment the sleeve is provided with an extension which is adapted to cover part of the arm above the wearer's elbow the sleeve and extension being joined by a bellows-like part. Figs. 14 and 15 illustrate another sleeve here the sheet 57 being cut along the lines 60, 61, such that after the edges 58 have been joined together the flap-like part 63 is turned about the hinge-like part 64 so that the holes 59 coincide. Additional pieces of material 70 are attached to the inner surface of the sleeve to help prevent the sleeve from slipping off the fore-arm. The flap 63 could be folded down upon the inner face of the sleeve instead of the outer face. Any of the sleeves described could be made from inflatable material and they could also be moulded either in their final shape or in their sheet form.

Abstract: Coffee beans, free from caffein, are impregnated with coffee extract also free from caffein at a fairly high temperature, e.g. 80 to 90 DEG .  During this process, concentration of the extract occurs due to evaporation.  The liquid loss due to this cause and the consequent thickening is eliminated by addition of further extract.  By this means, a full flavour and odour are restored to decaffeinized beans.

As shown, the valve member is positioned by a rotary sleeve 25, connected by a lever 12 to a driver's control, to select the forward clutch which is connected to a port 34, but the latter is connected by a channel 39 with exhaust 36 because a shaft 19, slidable in the sleeve 25 and connected to the valve member by a pin 29, is in its leftmost position to which it is urged when the vehicle brakes are applied. As the brakes are released the shaft is moved to the right and takes with it the valve member, which is slidable on a key 24, so that a land 42<SP>1</SP> moves past the port 34 to admit pressure fluid from a channel 38 to the port 34, the channel 38 being connected by an annular passage 42 and a channel 37 with an inlet port 33 from a pump 9. At the same time a spring 45, which opposes the loading spring 44 of a pressure regulating valve 46, is relaxed so that the pressure in a chamber 48, and thereby the pressure at the port 33, is increased. Fluid discharged through an outlet port 52 of the valve 46 is conducted to an hydraulic torque converter in the drive line between the vehicle engine and the forward and reverse clutches. To select reverse the sleeve 25 is turned to align the channels 38, 39 with another port (35, Fig. 3, not shown) connected to the reverse clutch.
