Title: Radio receiver frequency control system
Inventor: RAGAN LAWRENCE H
IPC: G08B5/22
Filed: 1990-07-23
Abstract: (57)Abstract Frequency control in a miniature receiver is effected by a synthesizer (42) that is operated briefly to provide a tuning vol-tage to a voltage controlled local oscillator (85). A capacitor is shunted across the output of the synthesizer (42) and is charged to the level of the tuning voltage. After the capacitor is charged, the synthesizer (42) is deenergized and the diminishing voltage pro-vided to the oscillator (85) by the discharging capacitor is correspondingly supplemented by an AFC voltage that tracks drift of the received signal in the IP passband. The deenergizing of the synthesizer eliminates synthesizer noise and reduces the receiver's power consumption.

Title: Quantum non-demolition optical tapping
Inventor: DORAN NICHOLAS J
IPC: G02B6/28
Filed: 1990-09-13
Abstract: A single silica optical fibre (4) is formed into a Sagnac interferometer (2) by forming a fused, dichroic optical fibre coupler (8) having four ports (10, 12, 14 and 16). A 1.3µm optical data signal is coupled to the port (10) via a dichroic optical fibre coupler (18) which combines it with a 1.53µm c-w probe signal from laser (16). The coupler (8) splits the 1.53µm probe signal into two equal intensity, counter-propagating portions and couples the 1.3µm data signal so it propagates in one direction round the loop (6). The loop (6) exhibits a non-linearity such that the data signal provides a relative phase shift of the counter-propagating c-w probe portions causing a portion of the 1.53µm signal is switched to port (12). This 1.53µm switched output provides tapping of the data signal without affecting its intensity.

Abstract: A gripper for use in a conveying device which conveys printed products is disclosed. The gripper has two gripper parts which are mounted so as to be freely pivotable on a shaft. The first gripper part can be pivoted between an open position and a clamping position.      This purpose is served by a closing lever which is seated on the shaft so as to be fixed against rotation. The rotary movement of the shaft is transmitted via a resting part, which is connected to said shaft so as to be fixed against rotation, and a compression spring which is supported on the resting part and, at the other end, acts on the first gripper part. The closing lever supports a follower roller which is mounted so as to be freely rotatable and interacts with closing links or cams. A locking device is provided for locking the first gripper part in the clamping position. In order to allow the first gripper part to close in any pivot position of the gripper and with the gripper moving in opposite directions, the closing lever encloses an angle a which is less than 90° with the first gripper part.

Information identifying the inoperative disk is written into a specified identification region of the parity disk to indicate that such operation has occurred.  The new data is then written into the corresponding sector of the operative disk.

Title: Detoxification
Inventor: DAMON LAURA L
IPC: B08B3/08
Filed: 1993-03-19
Abstract: Abstract Detoxification Increasingly severe restrictions are being imposed or contemplated as to the manner of disposal of ore bodies which have been leached with toxic lixiviant solutions such as alkaline cyanide.   Detoxification procedures in for example heap leaching both lengthen the overall time for a complete process cycle from heap building to heap dispersing and limit the proportion of time in which a heap is productive of metals.   The detoxification process of gold/silver ore bodies is accelerated and the extent of detoxification enhanced by incorporating within the ore body a small amount of calcium peroxide, such as from about 0.25 to 5 kg per tonne of ore, and advantageously, the calcium peroxide can be incorporated during the building of the heap.

Title: Tool-less threaded connector assembly
Inventor: STOKES KENNETH B
IPC: A61N1/375
Filed: 1993-04-13
Abstract: TOOL-LESS TREADED CONNECTOR ASSEMBLY                   ABSTRACT A lead connection suitable for use in connecting a flexible coiled lead to an implantable device. The implantable device is provided with a threaded projection having an outer diameter sized with respect to the inner diameter of the lead's conductor coil to provide a secure interconnection therewith when attached thereto. The threaded projection is disposed on top and around a feedthrough pin projecting out of the implanted device's hermetic canister. The threaded projection is screwed into the conductor coil establishing sound electrical contact between the projection and the conductor. A strain relief collar surrounds the post and lead, and a twist-and-pull type connecting ring surrounds the base of the strain relief collar. The connecting post is prevented from being unscrewed from the conductor coil, since an unscrewing motion tends to tighten the conductor coil around the threaded post. Since no connecting structure is required at the connecting end of the lead, the lead can be cut to any appropriate length at the time of implant, thereby eliminating problems with excess implanted lead. If disconnection is required, the lead may be simply cut off just beyond the threaded connecting post, or the post may be unscrewed by applying inward radial or circumferential pressure on the conductor coils. In an alternative embodiment, the threaded projection is replaced with a tapered triangular post with either smooth or toothed edges, which is inserted into the coiled conductor lead.

Abstract: A mounting structure for drivingly connecting a belt driven attachment such as an auxiliary blower to a mower deck or similar implement.  The connecting structure includes a pivot and sleeve arrangement between one end of the blower and the mower deck for quickly and easily positioning the blower on the mower deck.  The pivot then allows for the blower to be swung around adjacent to the mower deck to permit a latching mechanism to be engaged between the mower deck and the blower. The combination latching and belt tensioning mechanism permits generally simultaneous belt tensioning for belt driven blowers as the rear of the blower is latched to the mower deck. Should the latch not be aligned and, therefore, not secure the mower to the blower deck, provision is made for the belt tensioning arrangement to not engage the blower attachment adequately with the mower's belt drive.

Abstract: ABSTRACT   802.2 VIRTUAL DEVICE DRIVER    In a computer network having a plurality of nodes with one or more computer systems associated with a node a method for transmitting messages to and from a DOS application resident in a memory to and from the network. The messages to and from the DOS application are handled a virtual device driver resident in the memory which is monitoring the 5C interrupt. The virtual device driver converts an outgoing CCB1 message from the DOS  application to  a message in a CCB3  32-bit format and an incoming 32-bit CCB3 message to a CCB1 format. The virtual device driver transmits the CCB3 message to a physical  device  driver  resident  in  system  memory.  The physical device converts messages between the CCB3 32-bit format and a CCB3 16-bit format. The physical device driver transmits and receives 16-bit CCB3 messages to and from a logical link control protocol driver resident in the memory. The  logical  link  control  protocol  driver  is  preferably written to the ISO 8802-2 standards and passes and receives messages to and from the MAC layer and the LAN adapter. With an incoming message the virtual device driver arms a context hook which fires when the operating system has allocated sufficient memory to the DOS application resident Virtual 86 mode  before  transmitting  the  CCB1  message  to  the  DOS application.
