Title: Improvements relating to liquid delivery apparatus for spraying or irrigating parts of the body
IPC: A61M3/02
Filed: 1944-10-02
Abstract: 572,969. Sprayers. SMITH, F. Oct. 2, 1944, No. 14324. [Class 69 (iii)] [Also in Group VI] In a medical spray, comprising a casing A, drainage outlet C and air admission pipe D, the nozzle B is detachable or adjustable with regard to the casing and adapted, as by threading, to receive any of a number of extension devices for spraying or irrigation. The casing A may be fitted with a resilient cushion at its upper edge to enclose the part to be sprayed, or for internal use an extended nozzle O may be surrounded by a fitting R having a base P forming a cover for the casing. With either arrangement, by intermittently closing the pipe D, suction is created in the casing and transferred to the part being sprayed. Closure of the pipe D may be effected by a finger of the operator or by the provision of a needle valve which may be manually operated or as shown in Fig. 3 opened and closed by differing pressures in the casing acting through a pipe M on a spring-controlled piston K integral with the needle valve L and moving in the cylinder J. In a modification, the casing A and its attendant parts are adjustably mounted by means of a packing and gland nut on an extended nozzle instead of on the part B. Specification 552,596 is referred to.

IPC: E05D7/083
Filed: 1960-04-26
Abstract: 910,567. Hinges and pivots. ATVIDABERGS INREDNINGAR A.B. April 26, 1960 [April 30, 1959; Sept. 7, 1959], No. 14654/60. Class 65 (2). A friction pivot bearing for a horizontally or vertically pivoted window comprises a mounting plate 2 having a non-circular central pin 3 which is rotatable in an outer casing 5 non- rotatably secured to an inner casing 10 and a mounting plate 1 connected to the casings by means of a flange 9 which enters a slit 11a and has a transverse recess 15 engaged by a locking member 13 which prevents relative movement between the flange and the casings except when the window has been swung about 180 degrees from its closed position, braking discs 14, 28, 29 which have non-circular central holes similar in shape to the pin 3 and braking discs 21, 22 which have circular central holes and engage the inner casing 10 at their peripheries being placed on the pin 3 and urged together by a spring 20. The braking discs, which include the bottom 6 of the outer easing 5, are separated by plates b of friction material e.g. nylon, and the pressure of the spring 20 is adjusted by a screw 16 freely rotatable in the pin 3 and screwed into a disc 17 abutting the spring. The screw 16, the end 18 of which is retained in a hole 19 in the inner casing 10 by a locking ring or other means, also serves to hold the two casings together, relative rotation between the casings being prevented by a depression 7 in the circumference of the outer casing which engages a recess in the inner casing. Peripheral tongues (not shown) on the discs 28 and 29 are stopped by the depression 7 and limit the rotation of the bearing. The slit 11a is -formed by a divided plate 1a secured on the casing 10 and communicates with a diametrical depression 11 in the casing, and the flange 9, which is T-shaped in section, may be inserted or removed through a recess 8 in the outer edge of the casing 5 when the window is in the 180 degrees open position, as shown in Figs. 1 and 2. The depression 11 is formed with a slit 12 corresponding to the recess 15 in the flange to receive the locking member 13 which consists of an outwardly directed part of the disc 14. The rotation of the bearing may be limited, e.g. to 30 degrees, by a stop pin 33 screwed into the mounting plate 2 and engageable with an annular slit 34 in the bottom 6 of the outer casing. In a modification intended for the lower pivot of a vertically pivoted window, the flange 9 is rectangular in section. In a further modification the locking member is a spring-loaded pin which may be made to release the flange 9 in the 180 degrees position by engagement with a curved flange.

Title: Motor-alternator with automatic start-stop control
IPC: H02K47/04
Filed: 1976-04-12
Abstract: 1509825 Control of D.C. motors APPLIED MOTORS Inc 12 April 1976 [17 April 1975] 14853/76 Heading H2J A motor-alternator set for supplying A.C. to a load 17 includes a control circuit for starting and stopping the motor 19, the control circuit comprising a current limiting resistor R6 and a diode D2 which are supplied with current from a battery 13 so that when a switch 16 is closed, the potential across the diode causes current to flow through a resistor R1 to energize a relay CR1 thereby connecting the motor 19 to the battery and the motor driving the alternator 20 to supply A.C. via diodes D1-D4 to the load. The load may be a transformer or a motor for drive a power tool. When the switch 16 is closed, the potential across the diode D2 causes a current to flow through the resistor R1 via the alternator 20, the switch 16 and the load 17. The potential across the resistor R1 switches on a transistor Q1 which is turn switches on transistors Q2, Q3 to connect the relay CR1 to the battery. Relay contacts CR1-a are therefore closed to connect the motor to the battery. The motor drives the alternator, the positive half cycles from which are conducted by the diodes D1, D4 whilst the negative half cycles are conducted by the diodes D2, D3. During the positive half cycles the voltage Vc across the resistor R1 rises to the sum of the voltage drops across the diodes D4, D1, D2 to switch on the transistor Q1 in each positive half cycle. During negative half cycles the polarity of the voltage Vc is reversed so that the transistor Q 1 is turned off. A capacitor C1 however holds the voltage across resistors R3, R4 during the negative half cycles to prevent the relay being de-energized. When the switch 16 is opened the voltage Vc falls to zero so that the relay is de-energized and the load supply is therefore cut off. If the load has a shunt capacitor, opening of the switch 16 may not switch off the motor 19. To prevent such malfunction, a large value capacitor may be connected across the diodes D2, D3. Alternatively the series combination of a resistor and a transistor may be connected in parallel with the resistor R1, the transistor being switched on to connect the series resistor in parallel with the resistor R1 when the switch 16 is opened to ensure that the motor is switched off.

Abstract: 659,528. Stockings; sewing - machines. OLIVER, T. A. June 7, 1949, No. 15134. Drawings to Specification. [Classes 112 and 141] Stockings have the leg portion made on a circular Jacquard machine and the foot portion separately on a flat or circular machine with half the number of stitches per inch to make the fabric of the same weight as that of the leg, the two parts then being stitched together; if the leg is ribbed, the two parts will have the same number of front loops per inch. Linking-machines have alternate points longer than the others, so that when ribbed fabric is to be sewn it is only necessary to place the front loops on the long points, the back loops being then automatically guided on to the short points. When such fabric is being joined to plain fabric having the same number of stitches as the ribs, the stitches of the plain fabric will be placed only on the long points, the stitching automatically taking in the free back loops of the ribbed fabric on the short points.

As shown, each of eight segments 10 is provided from flat metal plate by angled cuts of alternating direction. With the segments assembled in a regular octagonal arrangement, parallel sided spaces E are defined between adjacent segment longitudinal edges. In each space E is inserted, and held by wedges 57, an electrode 20 comprising bars 52-55 of filler metal alternating with and welded to filler wire guide tubes 56. Each space E is closed by inner and outer copper battens 21, 22 which project beyond the upper and lower ends of the segments and have attached thereto cooling tubes 23, 24. After depositing flux powder in the space E and with electrical power connected between the electrode 20 and one of the segments, electro-slag welding is effected, filler wire being fed (by means not shown) to the wire guide tubes as welding proceeds upwardly. After welding, the battens 21, 22 are removed. The segment members may be joined one pair at a time in sequence (thereby reducing power demand), four at a time to provide two halves which are then welded together, or all simultaneously. The fabricated structure thus formed is then heat treated, for grain refinement and weld resilience improvement, forged, and machined to produce a substantially cylindrical member (Figs. 6, 7, not shown). In Fig. 2 (not shown), each segment comprises two parallel sided flat elements electro-slag welded together. In Figs. 8, 9 (not shown) a flanged pipe is formed by electro-slag welding together L- shaped segments each comprising a flange element electro-slag welded to a pipe element.
