Title: Rotary vacuum pump
IPC: F04C29/00
Filed: 1965-07-13
Abstract: 1,063,684. Lubricating. NEW YORK AIR BRAKE CO. July 13, 1965 [July 31, 1964], No. 29619/65. Heading F2A. [Also in Division F1] A system lubricating an oil-sealed mechanical vacuum pump, comprises a reservoir (25) open to atmosphere and positioned above the pump, the reservoir supplying lubricant through a line (26) to the pump bearings and thence to the pump interior, and also supplying lubricant through a valve controlled connection (31) to the pump suction inlet, the valve (32) being closed by pressure response means (34) when the pressure in suction connection (19) falls below a predetermined value. Gas is discharged by the pump into an air space above the oil in the reservoir before passing to atmosphere through oil separator (29), thus when the gas flow is high, i.e. on starting, a back pressure is created in the air space which assists lubricant flow. On starting the pump, the pressure difference across it is small and insufficient lubricant is supplied through the bearings. However, when the pressure in inlet (19) is above a predetermined value pressure sensitive switch (34) opens solenoid valve (32) and allows lubricant flow through the connection (31). The high gas flow on starting draws lubricant through a nozzle (36) in inlet (19) at the end of pipe (31). When the pressure in inlet (19) falls below a predetermined value, valve (32) closes, but the pressure difference is then sufficient to supply lubricant through the bearings. Opening of switch (28) to stop the pump opens solenoid valves (27, 32) to stop flooding.

Title: Pectin composition
IPC: A23L29/231
Filed: 1960-08-29
Abstract: Rectin compositions for forming jellies of optimum tartness and optimum pH for the most efficient pectin utilization comprise mixtures of pectin, a dispersant, fruit acid and adipic acid. The dispersant, which provides bulk to the composition, keeps the pectin and the acids separate, provides soluble solids and sweetens the jelly, is exemplified by dextrose, sucrose and lactose.  The fruit acid includes citric, fumaric, tartaric and phosphoric acids.  The amount of adipic acid may be 40-90% of the total acids.  The desired pH is 2.7-3.0.  Pectins in which the degree of methylation (% neutralization of free carboxyl groups) is 60-73 are advantageous.

Title: Improvements in or relating to hose couplings
IPC: F16L33/207
Filed: 1956-09-28
Abstract: 801,044. Hose end fittings. PARKER APPLIANCE CO. Sept. 28, 1956 [Oct. 4, 1955], No. 29736/56. Class 99(1). A hose 3 is frictionally gripped between a socket 7 and a nipple 1, the socket 7 having relatively blunt and sharp internal ribs 11 and 12 respectively, the latter cutting a continuous thread in the outer surface of the hose and the minor diameter of the ribs 11 being at least as great as that of the ribs 12. The socket 7 has a threaded bore 8 into which the nipple 1 screws so that a tapered end 4 extends through the socket, adjacent to the bore 8 there being an annular recess 9 in which the hose end is compressed and held against withdrawal by an abutment shoulder 10. The remaining length of socket 7 is internally threaded to provide the ribs 11, 12, the truncations of ribs 11 being relatively wide compared with the truncations of ribs 12 and the ribs having equal major, minor and pitch diameters and equal pitches. Preferably the width of ribs 11, 12 at their major diameter is less than one-half of the width of the grooves between them and the depth of the ribs is the same as the thickness of the outer layer of hose 3. Between the sharp rib 12 and blunt ribs 11 there is an intervening rib 13 which has a progressively widening minor diameter truncation. The major diameter of ribs 11, 12 is the same as the outside diameter of the hose 3 and the outer end of socket 7 is counter-sunk to facilitate the hose entry. In assembling, the hose 3 is threaded into socket 7 so that the sharp rib 12 embeds in the hose outer layer 16 and cuts through it, the rib 13 progressively spreading apart the helical cut made for positioning the blunt threads 11 to directly engage the reinforcing layer 15 of the hose, the engagement being continued until the hose end abuts the end of the recess 9. The hand of the ribs 11, 12 is opposite to that of the thread 8 so that when finally the nipple 1 and socket 7 are screwed together the hose is securely tightened and the tapered end 4 of the nipple jams the hose into the grooves between the ribs 11, 12 and compresses the hose end into the recess 9. There are provided three gripping zones ; (a) between the recess 9 and largest diameter of nipple 1 in which the hose abuts the shoulder 10, (b) between the blunt ribs 11 and large portion of nipple 1 wherein the minor diameter of the ribs exerts a high pressure clamping action directly on the braided reinforcing layer and (c) between the remainder of the ribs and tapered portion 4 of the nipple where the pressure is gradually lessened so as to avoid a high pressure concentration plane at the junction of the socket end and hose 3. The threads 8 and ribs 11, 12 may be lubricated on assembly and the fitting may be reused since the blunt ribs 11 are not deformed by contact with the wire braid 15 and the sharp ribs 12 are not damaged by contact with the braid 15. The sharp ribs need not have knife edges but may be truncated to approximately 0À01 inch and the included angle may be 30 degrees less for saw-tooth form or 60 degrees or less for V-form.

Title: Elevator control system
IPC: B66B1/52
Filed: 1956-10-04
Abstract: 804,191. Automatic speed control systems; control of D.C. motors. ALLMANNA SVENSKA ELEKTRISKA A.B. Oct. 4, 1956 [Oct. 5, 1955], No. 30245/56. Class 38 (4). [Also in Group XXXVII] In an elevator control system the speed of the car is influenced according to its position by a magnetic memory and a pick-up device, the former of which may comprise a magnetic tape, drum, or disc, arranged to move in correspondence, in respect to the pick-up, with movement of the car. A magnetic drum arrangement, driven by a chain attached to the car, in which the pick-ups traverse the length of the drum on a lead-screw when the drum is rotated, is described with reference to Fig. 2 (not shown). Driving-motor 40, Fig. 4, of a Ward-Leonard arrangement is controlled in accordance with the difference between the output of tachometer generator 45 and a portion of the reference voltage applied to terminals 53 selected by relay 71 from potentiometer 52 in a regulator 39 controlling the field 43 of generator 42. The magnetic drum 20 carrying signals such as shown in a development, Fig. 5, is brought into operation by a relay 74 when the selected contact on the position indicator 82 is closed by the car approaching the required floor, and energization of relay 71 is transferred from source 80 to the output of pick-up 32. The relay 71 is held whilst the pick-up is traversing signal 324 but releases at point t2, Fig. 6, to connect the slowing speed reference tapping from potentiometer 52 to the regulator. At point t4 when the car speed has acquired the desired slow running speed, signal 314 energizes relay 51 through pick-up 31 and amplifier 35 to apply brake 47 and bring the car to rest. Oppositely poled rectifiers 57, 58 in the input to regulator 39 provide for current limitation, and control of direction is effected by relays 67, 61, reversing the polarity of the reference voltage. In a modification described with reference to Fig. 7 (not shown) the speed-dependent voltage is provided by a further continuous signal 330 on the track, Fig. 8, and slowing is effected by transferring the control to a signal 320 wherein the frequency of the recorded signal is increased in predetermined regions to introduce a signal larger than the reference voltage. Reversal in this embodiment is achieved by changing over the output leads from the Ward-Leonard generator.
