Abstract: A reciprocating saw (10) including a housing (12), a spindle (14) mounted for reciprocation relative to the housing and having a front end adapted to support a saw blade (18), the spindle being movable through a cutting stroke and a return stroke, a motor (20) for moving the spindle in a reciprocating fashion, and a reciprocating member (40, 50) interconnecting the motor with the spindle. The motor and the spindle define a drive force path from the motor to the spindle and passing through drive force bearing components of the reciprocating saw, and wherein at least part of the reciprocating member is in the drive force path. The reciprocating member is configured to counterbalance the spindle. A pivot body (50) interconnects the spindle with the motor. A shock absorber (66') is operatively positioned between the motor and the front end of the spindle, and is at least partially mounted within the spindle.

IPC: B09B1/00
Filed: 1999-11-04
Granted: 2008-05-28
Abstract: A process for treating earth materials such as rock heaps to prevent acid rock drainage therefrom is disclosed. First, the oxygen concentration in the gas-phase of the rock heap is decreased, that is, displaced and/or depleted. This first step may be accomplished physically, chemically or biologically. Then, the gas-phase oxygen concentration in the heap is maintained at a low level. This second step may be provided for in a self-sustaining manner, like, for example, by covering the rock heap with soil and vegetation so that acid rock drainage is prevented indefinitely. Alternatively, the density of the gas-phase of the rock heap may be increased, and maintained at an elevated level indefinitely. The process is applicable to waste heaps from mining and industrial operations such as power generation and minerals processing, and to rubble collections in open and closed mines.

Title: Forsinket svelling i et brønnpakningselement
Inventor: WOOD EDWARD T
IPC: E21B33/127
Filed: 2009-01-30
Abstract: Et svellingselement hastighetsreguleringsteknikk og produkt kjennetegner en ytre belegning på en kjerne av et element. Kjernen reagerer på hydrokarboner eller vann avhengig av hvorledes den er utformet. Den omgivende belegning er fortrinnsvis formet av fine jordpartikler av et ikke-svellende polymer blandet i et oppløsningsmiddel slik som metyl-etyl-keton som er påført i et tynt lag til kjernens ytre. Det uherdede ytterlag er så kontaktet ved en mønstret overflate. Den mønstrete overflate er presset fast mot den ikke- herdede polymer/oppløsningsblanding og overfører en invers av mønstret til overflaten av betegningen. Ettersom trykk påføres, kan varme også anvendes for å herde betegningen. Det resulterende mønster er utformet slik av åpninger i betegningen er skapt som regulerer infiltrasjon av vann eller andre fluider gjennom det og, som et resultat, svellingshastigheten i brønnboringen. Svellingshastigheten styres delvis av forholdet av det eksponerte areal av svellingssammensetningen til det totale volum av svellingssammensetningen. Jo mindre dette forhold er, jo lavere er svellingshastigheten. Mønstret skapt i det ikke-svellende laget kan også sørge for begrenset mekanisk tilbakeholdelse av svellingselementet, som videre sinker prosessen.

Title: Electronic locking system
Inventor: SCHWERDT FRANZ
IPC: E05B49/00
Filed: 1993-03-05
Abstract: An electronic locking arrangement comprising a lock unit (17) and a key unit (19) is proposed. Each of the units has a control circuit (35, 41) and a transmitting and receiving circuit (33, 47, 39, 43) which transmit information signals inductively via coupling coils (21, 23) to the control circuit (35, 41) of the other particular unit. The transmitting and receiving circuit of the lock unit (17) has an amplitude modulator (33) and a frequency demodulator (47) for the transmission of the information signals, whilst the transmitting and receiving circuit of the key unit (19) comprises a frequency modulator (43) and an amplitude demodulator (39). In dependence on the information signals transmitted between the units (17, 19), the control circuit (35) of the lock unit (17) generates a control signal representing the locking state. The transmission of the information signals takes place via a single pair of coupling coils (21, 23) utilised in both transmission directions. The amplitude modulator (33) modulates the high-frequency signal of a free-running high-frequency oscillator (27), the frequency-determining circuit of which comprises the coupling coil (21) of the lock unit, whilst the amplitude demodulator (39) is connected to the coupling coil (23) of the key unit (19). The frequency modulator (43) is likewise connected to the coupling coil (23) of the key unit (19) and detunes the frequency-determining circuit of the high-frequency oscillator (27) in dependence on the information signal to be transmitted. The frequency demodulator (47) is also coupled to the high-frequency oscillator (27). The locking arrangement permits high locking security, along with a high data transmission rate, at a comparatively low outlay in terms of structural parts. <IMAGE>
