A fountain type coffee percolator, Figs.1 and 2, (not shown), has a variable thermostat which may be set according to both the amount of water within and strength of coffee required. The thermostat 27, which contacts the bottom of the container portion of the percolator, has an adjustment screw 26 which acts on the contact leaf 32. The screw is rotated by means of the lever 25 whose slot 24 engages the pin 23 on the lever activating arm 21. Thus the thermostat is set by movement of arm 21 by means of a knob 12 which moves past a scale (13) graduated in numbers of cups. The knob has three regions, weak, medium and strong, indicated in some manner and in operation the appropriate region is aligned with the appropriate number of cups, see Fig. 1, (not shown). Alternatively the knob may have a single pointer and the scale may be movable to set the strength, either indicated by a pointer on the scale co-operating with a second scale or a fixed pointer co-operating with a portion of the scale. The thermostat may be adjustable continuously or in discrete steps. Alternatively a number of thermostats set to different temperatures may be used, the appropriate one being selected by the control mechanism.

Abstract: 1289108 Respirators A L SPILLER 1 Dec 1969 [13 Dec 1968] 59425/68 Heading A5T [Also in Division F1] In a respirator wherein a pump 11 provides respiratory gas to a patient; the drive system for the pump comprises two spaced parallel rods 14 and 17 linked by a lever 20 supported by a fulcrum comprising a bush 23 and support 24, a second lever 27 pivotally connected to the rod 17 at 30 and supported by a second fulcrum comprising a bush 31 and support 32 and a driven rotary arm 37 having sliding connection with the second lever and connected to an electric motor 35. The fulcra are movably supported on locating bars 25 and 33. Rod 14 is connected to a piston 12 in a cylinder 13 having an inlet 39 and outlet 40. The whole device is secured to a base board (10). Motion of motor 35 is transmitted through arm 37 and lever 27 to reciprocate rod 17 which in turn causes piston 12 to reciprocate by means of lever 20 and rod 14. The positions of the fulcra regulate the times and magnitudes of forward and reverse movements of the rods. A gas source is connected to the inlet through a one way valve (41) (Fig. 4, not shown). Outlet 40 has a one way valve (42), then a branch (44) to the patient and another branch containing a solenoid operated valve (45) triggered by movement of rod 17, and a flow restrictor (46). An excess pressure safety valve (47) is also provided. The restrictor (46) is controllably linked to rod 17 by a cam system (see Fig. 5, not shown). A further piston and cylinder may be connected to rod 17.

Abstract: 1297275 Tobacco separator HAUNIWERKE KORBER & CO KG 18 May 1970 [26 June 1969] 23963/70 Heading B2H A tobacco separator for pneumatically separating tobacco ribs from a mixture of tobacco leaf portions and tobacco ribs comprises two separating chambers 8, 9, Fig. 1, arranged one above the other and connected by two ducts 12, 13, and a tobacco accelerating means 27 which is provided in, or in the region of, the mouth of a tobacco mixture feed device 2 leading into the lower separating chamber 9 to throw the tobacco mixture across the chamber 9 transversely to a separating air current flowing therethrough whereby the light tobacco leaf portions are carried with the air current into the upper separating chamber 8 substantially via the duct 12 and heavy tobacco constituents, e.g. ribs with attached leaf portions, entrained in the air current into the upper chamber 8 are returned therefrom to the lower chamber 9 via the duct 13, the accelerating means 27 being arranged in relation to the duct 13 in such a manner that it projects the returning tobacco constituents again across the chamber 9 transversely to the separating air current. The ducts 12, 13 are defined between the walls of the tobacco separator and a pivotable' guide body 11. The chambers 8, 9 and the ducts 12, 13 are bounded by adjustable walls 14, 16, 17. The feed device 2 comprises a belt 23, a metering cell wheel 24 and an angularly adjustable chute 26. The accelerating means takes the form of a winnower roll 27 which, on throwing the tobacco mixture across the chamber 9, also effects a preliminary separation of the relatively heavy ribs which fall downwardly in the direction of the arrows 58. A fan 6 sucks air from the upper separating chamber 8 through an extractor 3 which separates the tobacco leaf portions from the air, and through a pipe 33 and forces air back into the lower operating chamber 9 via a pipe 36, air feeders 37, 38 and perforated walls 14, 16 of the lower chamber. An auxiliary air flap 34 is provided in the pipe 33 to compensate air losses and a restriction valve 39 is fitted in the pipe 36 for adjusting the amount of air. A branch pipe 41 connected to the pipe 36 upstream of the valve 39 and fitted with a further restriction valve 32 leads to a dust filter 4 for extracting dust from the circulating air current. The amount of air supplied through the air feeder 38 is less than that supplied through the air feeder 37 and flows mainly from the chamber 9 through the duct 13 into the chamber 8 whereby a pressure difference is produced at the mouths of the ducts 12, 13 inducing the heavy tobacco constituents entrained into the chamber 8 to seek the path of lower resistance and fall through the duct 13 back into the chamber 9 in the direction of the arrow 61. In a modification, Fig. 2, the accelerating means take the form of a pneumatic nozzle 128 pivotably adjustable about a spindle 129 and connected to a compressed air supply via a valved pipe 132.

Abstract: 1301496 Two-stage fluid pumps; radial piston pumps; rotary positive-displacement pumps APPLIED POWER INDUSTRIES Inc 2 Oct 1970 [31 Oct 1969] 46990/70 Headings F1A and F1F A two-stage fluid pump comprises a Gerotor pump 4 and a radial piston pump 5 driven by a common shaft 2, the two pumps being able to operate together to discharge fluid to a common outlet or the radial piston pump 5 operating alone but fed by the Gerotor pump 4. The Gerotor pump 4 has two discharge passages, one leading to an outlet 24 and the other leading via a passage 23 and annular passage 25, to passages 26, 28 in each of three pump bodies B of the piston pump 4 and thence to the respective piston chamber 30. The shaft 2 has an eccentric portion 33 on which is mounted a needle race 34 having a flat 40. One of the pistons 31 engages the flat so that the race 40 is held in the same orientation relative to the apparatus as the eccentric 33 rotates. The pistons 31 are thus reciprocated by such rotation. The piston pump 5 discharges fluid to an outlet 11. When both pumps operate together fluid flows from the two outlets 11, 24 to a common passage 10. The Gerotor pump outlet discharge can be dumped by a valve 8, so that the piston pump operates alone, being fed through passages 23, 25, 26, 28 by the Gerotor pump.
