Patent EP-0351013-A2 (EP)
Inventor: BERTRAM LEO
IPC: F04D15/02
Filed: 1989-07-10
Abstract: The invention relates to an assembly having a container (1) which can be filled with a liquid and has an outlet opening (4) and having a pumping device (5) with a pump chamber (11) and a pump impeller (10), revolving in the latter, for accelerating the liquid, having a single-phase synchronous motor (5a) for driving the pump (5b) and having a pump inlet line (25) which is situated below the outlet opening (4) of the container and connects the latter to the suction connection (13) via a liquid shut-off means (19) arranged on the suction side, upstream of the pump (5b), in the liquid feed. A common control means (19) is provided for the pumping device (5) and the liquid shut-off means (17). The pumping device (5) is furthermore arranged below the outlet opening (4) of the container and the pumping device (5) is only electrically switched on by the common control means (19) if the pump chamber (11) is not yet or only to a small extent filled with liquid, for which purpose the control means (19) initially holds the liquid shut-off means (17) closed. After pump start-up, the common control means (19) opens the liquid shut-off means (17) with a time delay and, before the pumping device (5) is switched off, first of all closes the liquid shut-off means (17), after which the pumping device (5) is switched off with a time delay if the pump chamber (11) is empty or almost empty. A nonreturn valve (18) is arranged so close to the outlet connection (14) on the delivery side of the pump (5b) that the residual liquid flowing back into the pump chamber (11) after the switching off of the pump arrangement (5) and the activation of the nonreturn valve (18) only fills the pump chamber (11) to such a minor extent that the start-up of the synchronous motor (5a) is not hindered. <IMAGE>

Abstract: A multi-functional analog electronic watch has step motors for driving hands indicating ordinary time and for indicating additional functions. One step motor drives through a gear train an hour hand (12) and a minute hand (11) indicating ordinary time by rotating about a central axis. From the same gear train a second hand (14) is driven to indicate ordinary time by rotating about an axis eccentric to the central axis and disposed along the position of the hour hand at 9 o'clock. A second step motor drives through a gear train a chronograph second hand (21) indicating seconds elapsed since pushing of a switch operating button (24) by rotating about the central axis. A third step motor drives through a gear train a chronograph minute hand (31) indicating minutes elapsed since pushing of the button (24) by rotating about an axis eccentric to the central axis and disposed along the position of the hour hand at 12 o'clock. A fourth step motor drives through a gear train alarm minute and hour hands (38, 39) indicating an alarm time set or ordinary time by rotating about an axis eccentric to the central axis and disposed along the position of the hour hand at 6 o'clock. A first stem can be pulled to a position in which the ordinary time gear train can be rotated to correct the positions of the hour and minute hands (12, 11). A second stem (23) can be pulled to either of two positions, in one of which timer or alarm functions can be achieved. In the timer function mode, pushing of the   button (24) causes reverse stepping of the second and third step motors, so that the chronograph minute and second hands (31, 21) indicate elapsed time in seconds and minutes respectively.

Abstract: In a mass spectrometer system, ions travel through an orifice (26) in an inlet plate (28) into a first vacuum chamber (30) containing AC-only rods (32), and then through an orifice (34) into a second vacuum chamber (38) containing a standard quadrupole (40). The second vacuum chamber is held at low pressure, eg. .02 millitorr or less, but the product of the pressure in the first chamber times the length of the AC-only rods is held above 2.25 X 10⁻² torr cm, preferably between 6 X 10⁻² and 15 X 10⁻² torr cm, and the DC voltage between the inlet plate and the AC-only rods is kept low, eg. between 1 and 30 volts, preferably between 1 and 10 volts. This produces a large enhancement in ion signal, with less focussing aberration and better sensitivity at high masses, and also allows the use of smaller, cheaper pumps so the system can be more easily transportable.

Inventor: SEALS DAVID GEORGE
IPC: G08B25/10
Filed: 1990-06-21
Abstract: A system to monitor an electric fence or a secured area uses radio telemetry to report faults. The radio telemetry transmitter gathers data from a fence charge sensor, battery voltage sensor and/or switch contacts and encodes this information along with a unique address code in a serial data stream that modulates, by frequency shift keying (FSK), a radio frequency (RF) signal. A radio telemetry receiver intercepts the transmitted RF signal and compares the received address code to a preprogrammed unique address code. If code match occurs the received data is transferred to the appropriate displays. Various faults are reported visually and audibly. Fail-safe timers and error detector circuitry in the radio telemetry and transmitter receiver ensure the integrity of the radio telemetry link.

Abstract: In an image forming system employing a photosensitive drum (11) on which an electrostatic latent image is formed, and a toner image bearing belt (14) on which a toner image corresponding to the electrostatic latent image is formed by means of a developing device (17), a discharging device (33), such as an AC corona charger, is provided to face the toner image bearing belt superimposed on the photosensitive drum, at a location downstream of the developing area. The surface charges on the toner image bearing member (14) is therefore removed before or when the toner image bearing member separates from the photosensitive drum (11). As a result, the increase of the potential difference across the air layer due to the decrease of the capacitance of the air layer between the toner image bearing member and the photosensitive drum is prevented, and electrical discharge through the air layer, and attendant scattering of the toner image are thereby avoided.

Abstract: A system and method for reclaiming unreferenced computer memory space, also known as garbage collection operates in a virtual memory environment wherein user memory space is divided into pages. For each active page, a table stores the age of the oldest object on the page (A-value) and the age of the youngest object pointed to from that page (F-value). A generational partition divides the pages into "safe" pages and "threatened" pages, based on their A-values. Rescuer pages, which may contain pointers to threatened pages, are determined by comparing the F-values to the generational partition. All potential pointers on the rescuing pages are traced and the objects pointed to are marked as reachable. All objects reachable from other reachable objects are also marked. Unmarked threatened objects are de-allocated.
