Title: Lower pivot assembly and support for a swinging or folding door
IPC: E05D7/00
Filed: 1975-10-24
Abstract: 1503786 Door pivots ACME GENERAL CORP 24 Oct. 1975 [8 Nov 1974] 43713/75 Heading E2F A lower door pivot comprises a support 17 secured to the door surround and a pivot assembly comprising two cooperating screw threaded parts one of which 31 engages the door and the other being a pin 37 with an enlarged head 38 which is held against rotation relative to the support; the assembly being non-rotatably engagable with the support in a number of horizontally spaced positions by means of gear means on the head of the pin engaging a rack means on the support and being held in engagement by the weight of the door. In the embodiment shown a threaded plastics sleeve 31 ribbed at 32 is driven into a hole in the door and is screw threaded to pivotably receive a threaded pin 37 having a conical splined head 38. The head 38 engages in a slot 26 formed with serrated edges in the support and can be moved to any required position along the slot. Vertical adjustment of the door is effected by raising the head 38 out of the slot and screwing the pin 37 into or out of the sleeve 31. In modified embodiments the head can have teeth projecting from a lower flat face to engage a double row of holes along the support with a central projection on the face sliding along a slot between the rows (Figs. 6-11 not shown); or the head can have ribbed sides to engage the corrugated sides of a channel section support (Figs. 12, 13 not shown). Instead of the head and pin being disengaged from the support to allow the vertical adjustment, the head can be slidably (but non- rotatably) mounted on the pin so that only the head need be disengaged (Fig. 13 not shown). The support 17 is shown L-shaped in use at the corner of a door but can be flat for use away from the door upright. Two such flat supports or a single long support could be used for a double door arrangement.

Title: Apparatus for proportioning liquid additives
IPC: F04B13/00
Filed: 1974-10-18
Abstract: The dosing of solutions of chemicals into flowing water of a water pipe is effected, according to the invention, by a piston-cylinder pump (1, 2) which is driven, via a transmission (17) and eccentric(s) (29), by a hydraulic motor (3) through which the stream of the water main (23) is flowing. In order to avoid excess dosages, a valve (4) opens a bypass (22) when a predetermined pressure drop at the hydraulic motor (3) is exceeded. The solution flows from the reservoir (11) which is mounted onto an outlet spigot (13), into a chamber (10) and via a conduit (14), the dosing pump (1, 2) and a conduit (15) to the infeed point (16) on the water pipe (23). When a minimum filling level in the chamber (10) has been attained, a valve actuated by a float (8) opens a conduit (30) through which water reaches the chamber (10) from the water pipe (23). Thus liquid is always present in the chamber (10), so that it is not possible for any crystallisation to occur, for example when the reservoir (10) is emptied completely. <IMAGE>

Abstract: 1531265 Pressure sensors DANFOSS AS 5 Nov 1975 [6 Nov 1974] 45894/75 Heading G1L A fluid-pressure control device which operates a micro-switch 18 when the pressure in boiler 2 falls sufficiently, includes a sealed chamber defined by two hollow resilient members 11, 19 the effective area D 1  of the member 11 being greater than that D 2  of the chamber, the pressure in the chamber being below ambient whereby a leak in either member also causes the device to operate the micro-switch. When either the boiler pressure falls or a leak occurs the force on the spring 16 decreases and the arm 15 is pushed down to turn the switch 18 off. However, if a leak occurs when the boiler pressure is too high, the spring will not be able to move the arm against the pressure. In this case a second device 4 is used to open a second switch 38 when excess pressure occurs. This device also includes a protective bellows 31 outside bellows 27. A leak in either bellows also causes the switch 38 to be opened unless boiler pressure is too low; however this is detected by the first device.

Abstract: 1,020,008. Television; staircase waveform generators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 6, 1962, No. 46154/62. Headings H3P and H4F. In a scanning system for a cathode-ray tube, a set of auxiliary pulses is produced at the time of each horizontal line, the pulses being counted by a chain 22 of bistable trigger circuits, the output of which is converted in a decoder 24 to a staircase vertical deflection waveform. If the line/frame ratio is not an exact multiple of the number of pulses in each set the system will interlace at a rate corresponding to the number of pulses per set. Interlacing.-The Specification refers to double, triple and quadruple interlaced rasters and describes a triple interlaced system having eleven frames/second (33 fields/second) and 761 lines/frame. A pulse P1 is generated at the start of each spaced sawtooth horizontal sweep at 16, a further pulse P2 at the end of each sweep and a third pulse P3 at the end of each flyback. Each pulse P1, P2, P3 advances the counter 22 by one unit until a count of 897 is reached when the counter is reset by the AND gate 26 and an amplifier 28. (897 - 136=the line/frame ratio, 761.) Staircase wave generators.-The triggers 22 are each connected to a digital/analogue converter (Fig. 5). Temperature-compensated resistor 44 connected to the tenth trigger T10 is arranged to pass one half of the maximum output current of the decoder 24 whilst the values of the other resistors 40, 42 &c. are weighted on a binary scale. Diodes 46, 48, 50 become non- conductive when the corresponding trigger is in its " 1 " state, diverting an appropriate current from the relevant diode 52, 54, 46 to the output terminal 58. The staircase waveform thus produced during each count is amplified at 12 and fed to vertical deflecting plates or coils on a cathode-ray tube 14.
