IPC: F24F11/75
Filed: 1960-06-02
Abstract: 940,069. Valves. BUENSOD-STACEY CORPORATION. June 2, 1960, No. 19602/60. Heading F2V. [Also in Division F3] A fluid-flow regulator for controlling air to a room has a closure member loaded to open position to maintain a predetermined flow, closes with increase in upstream pressure and has inertia means movable in response to movement of the member for preventing rapid reversal movements. A housing 13 in a conduit 10 is open upstream at 16 and has a pitched downstream wall 14 with perforations 17 controlled by roller blinds 18 secured at the top to the apex of wall 14 and at the bottom to rollers 20, 20<1> forming the picot for two pairs of links 22, 26; 21, 25. The pairs 21, 22 are pivoted at the top to the apex and pairs 25, 26 at the top to a rod 30 sliding in two cross guides 21, 32 secured in the conduit, the rod being adjustably spring loaded upwardly at 33, 35 to open the blinds and having a rock 48 engaging a pinion 47 on the spindle of inertia wheels 44, 45. Movement of the blinds by the flowing fluid moves the rod 30 via the links and rotates the inertia wheels. The rod may carry an actuating cord wound round the inertia wheel spindle or may be screwed to rotate a nut carrying the wheel.

Abstract: 882,398. Wedge fastenings. RELIANCE ROPE ATTACHMENT CO. Ltd. June 18, 1959 [June 19, 1958], No. 19629/58. Class 44. A support comprises a base 1, a bore 5 extending therethrough, the bore wall including a tapered part, suspension member 3 having an enlargement 4 smaller than the smaller diameter of the bore so that it may be passed therethrough and tapered members located about the suspension member, abutting the enlargement and the wall of the bore at the tapered part, to prevent movement of the enlargement through the bore. As shown, the enlargement is of spherical shape and the wedge members are shaped at one end to engage the enlargement and at the other end to engage the suspension member which is of circular cross-section.

Title: Improvements in or relating to milling toothed gears
IPC: B23Q35/10
Filed: 1939-07-05
Abstract: 531,563. Gear-cutting JAGER. K., and BOPP & REUTHER GES. 'July 5, 1939, No. 19632. [Class 83 (iii)] In a machine for hobbing elliptical gear wheels the spindle f of the work g carries an elliptical master gear i rotated by a master worm s mounted in the tool carrier m which is moved to and from the work axis to generate the elliptical form by means of a master disc h on the work spindle co-acting with rotatable abutment q on the tool carrier. A weighted cable n maintains the abutment against the disc. The hob f which may be driven from a flexible shaft is mounted on a slide o movable vertically on the carrier m. Preferably the master wheel and the master disc are larger than the blank. For marking off the form of the disc h, Fig. 3, lines of length corresponding to the distance v are drawn from a number of points on the pitch ellipse of the blank in directions perpendicular to the tangents at such points. The form of the master gear i is obtained by prolonging radii of, the pitch curve of the blank, Fig. 2, to form a curve having radii which are increased in the same proportion as the pitch of the master gear teeth bears to the pitch of the blank teeth.

Title: Improvements in or relating to air conditioning units
IPC: F24F3/14
Filed: 1951-08-23
Abstract: 690,461. Cooling and drying air. CARRIER ENGINEERING CO., Ltd. Aug. 23, 1951 [Jan. 12, 1951], No. 19948/51. Class 137 [Also in Group XIII] Air is simultaneously cooled and dried by passing it through the evaporator of a refrigeration unit whilst flowing a hygroscopic liquid over the evaporator, the liquid absorbing the air moisture and then being distributed over the refrigeration condenser through which is directed a second stream of air, this air evaporating the moisture from the liquid, which is then recycled to the evaporator. In the form shown, the apparatus consists of a container 2 divided by a partition 3 into two compartments 4 and 5, a refrigerator compressor 9 and a condenser 10 being located in compartment 5 and the evaporator 12 in compartment 4. Air to be conditioned is drawn by a fan 7 into compartment 4 and discharged therefrom through the evaporator 12 which cools it to the desired temperature. A hygroscopic liquid such as triethylene glycol or lithium chloride or bromide or calcium chloride solution is pumped by a pump 19 from a sump 17 in the base of compartment 4 to nozzles 21 which spray it over the evaporator, the air moisture being absorbed and the diluted liquid draining back to the sump. Pump 19 also feeds part of the liquid through a line 22 to nozzles which spray it over the condenser 10, a fan 8 drawing a second stream of air through the condenser to evaporate the water from the hygroscopic liquid and also to condense the refrigerant, the latter then being forced by the compressor 9 through a pipe 13 and capillary 14 to the evaporator. The concentrated liquid drains into a sump 18 in the base of compartment 5 and overflows into sump 17 over a weir 19<SP>1</SP>. For further concentration of the liquid, a pump 25 maintains a local circulation of the liquid from sump 18 over the condenser. If a very low air dew point is not required in the room to be conditioned, the air leaving the evaporator may be sprayed with water through a nozzle 28, this also producing a further cooling effect. A thermostat 31 in the room space operates first to close a solenoid valve 30 in the water spray supply line when the room temperature falls below a certain point and subsequently to stop the compressor 9 if the temperature continues to fall.

Abstract: 1,024,113. Conveyers. HYDROMATION ENGINEERING CO. May 21, 1963, No. 20090/63. Heading B8A. A storage and transfer device particularly suitable for workpieces of irregular shape, consists of a fixed spiral trackway 31 surrounding a vertical rotatable axle 22 which carries flexible pushers 25 engageable with the workpieces to move them along the trackway when the axle is rotated. The form of the trackway is such that the workpieces thereon will project inwardly toward the pushers. In Figs. 3 and 4 the trackway consists of two pairs of rods 34, 35 mounted in inwardly open U-shaped frame members 36. The open ends of these members are linked by upper and lower plates 39 and 41 between which is left a helical gap 38 through which portions of the workpieces 37 may project to be engaged by the brushes 25. The latter constitute the flexible pushers and are adjusted, e.g. by screws, to run on the plates 39 and 41 and engage only the projecting portions of the workpieces. The disposition of the pairs of rods 34 and 35 and the form of the frame elements 36, 39, 41 associated therewith may be varied, e.g. as in Figs. 5 and 6 (not shown), to adapt the apparatus for different forms of workpiece. Also the brushes may be replaced by other flexible elements such as rubber strips 102, 103 (Fig. 5, not shown).

Abstract: 1,122,801. Data transmission systems; multiplex pulse code signalling; frequency modulation. SERCK CONTROLS Ltd. 18 Aug., 1965 [19 May, 1964], No. 20571/64. Headings H3R, H4L and H4P. Data in polar return-to-zero form is transmitted by representing Mark, Space, and Zero digits by three respective frequencies. At the receiver, each positive-going transition in the received frequencies causes the generation of three gating pulses, which sample the received signal at times corresponding to the possible times of the next positive transition to determine when that transition actually occurs. The time of occurrence indicates the received frequency and hence the data level. Reference is made to a time-division multiplex system in which the Mark and/or Space frequency of one channel acts as the Zero frequency of another channel which has different Mark and Space frequencies. The modulator, Fig. 2 (not shown), comprises cross-coupled transistors having frequency determining circuits, each including a plurality of resistors which are selectively shorted by transistors controlled by the data to produce the three frequencies.
