Abstract: An arrangement in a firearm for adjusting the clearance between the fore-end of the stock (2) and the barrel (1), the stock being stiffened by means of a stiffening rail (3), preferably of metal, fastened to it. To enable the adjustment to be carried out, the rear end of the stiffening rail (3) is fastened (4) rigidly to the stock (2), while between the fore-end of the stiffening rail (3) and the fore-end of the stock there is an adjustment means (5) which, during the adjustment, produces a lateral force between these parts in such a way that the clearance can be adjusted to be equal on both sides of the barrel. The adjusting means (5) can be a turning piece, fitted through the stock from below, the eccentric pin of the piece engaging in a notch in the rail (3).

Patent NO-164466-C (NO)
Inventor: JONES STANLEY GERNARD
IPC: B26D1/60
Filed: 1987-12-14
Abstract: In a machine for making paper booklets from a multiplicity of paper strips on bobbins that are converged into a continuously advancing strand a reciprocating cutting station (25) defined by leading and trailing plates (27, 28) performs the operations of firstly clamping the strand while the station (25) moves with the strand and secondly of cutting off booklet lengths of paper by means of a knife (156). Cut booklets are ejected into a discharge chute (32) by ejection means (200) including an ejector bar (211) terminating a thrust plate (214). According to the invention the ejection means (200) is separated from the cutting station (25) and is fixedly located opposite to the chute (32). Connection between the cutting station (25) and the ejection means (200) is established by a common rotating hexagonal shaft (76) which is operably connected to clamping and cutting mechanisms of the station (25) and which carries a pair of cams (207, 208) that actuate the ejector (211) through a parallelogram linkage. By this means the motion of the ejector (211) can be gradual rather than abrupt, the machine is easier to set up, and the ejector thrust plate (214) can span substantially the full width of chute (32) so that the likelihood of cut booklets becoming misplaced is reduced.

Title: Bidirectional helical electrode for nerve stimulation
Inventor: BULLARA LEO A
IPC: A61N1/04
Filed: 1989-10-12
Granted: 2001-02-13
Abstract: A circumneural electrode assembly having a pair of spaced-apart and oppositely directed helical portions which can be opened by an insertion tool to fit the assembly over a peripheral or cranial nerve. One or more conductive electrodes on the inner surfaces of the helical portions intimately contact the nerve surface to deliver electrical stimulating signals, or alternatively, to block nerve conduction or to sense evoked potentials. The surgically implanted assembly is stable in position on the nerve, and is installed with a minimum of nerve manipulation and possible resulting trauma. The assembly preserves the advantages of previously disclosed spiral electrodes, while greatly simplifying installation, particularly in a nerve which is deeply recessed in overlying muscle or arteries.

Title: Distributed bragg reflector laser for frequency modulation communication system
Inventor: CHRAPLYVY ANDREW R
IPC: H04B10/06
Filed: 1989-12-27
Granted: 1993-05-18
Abstract: DISTRIBUTED BRAGG REFLECTOR LASER FOR FREQUENCY MODULATED COMMUNICATION SYSTEMS          Abstract To overcome the deleterious effects of the nonuniform frequency modulation response in semiconductor lasers due to current injection in direct frequency modulation applications, it has been determined that the linewidth enhancement factor a be made as large as possible. In one embodiment, distributed Bragg reflector lasers well suited for frequency modulation lightwave communication systems are designed to have an integrated feedback element such as a corrugation grating whose effective pitch is selected to cause the Bragg wavelength and, therefore, the laser operating wavelength to be longer than the wavelength at substantially the maximum gain or gain peak in the semiconductor structure. Thatis, the wavelength of the grating is effectively detuned toward the longer wavelength and lower energy side of the peak of the gain profile. Such detuning increases the linewidth enhancement factor in such a way that the nonuniform frequency modulation response and its effects are minimized and, in some cases, substantially eliminated.

Granted: 2004-02-10
Abstract: A vacuum insulation panel having flexible gas impermeable walls formed in multiple substantially adjacent compartments. A thermal break may advantageously be provided around the perimeter to prevent conduction of heat from a warmer side of the panel to a colder side, which thermal break can be easily constructed by utilizing webs of gas impermeable material with the foil carried thereon such that the foil has a width somewhat less than the width of the film and with two separate pieces of the film rotated at 90° to one another to provide a continuous area void of the foil. Multiple compartments are utilized to enhance the long term thermal characteristics of the panel by "protecting" the vacuum characteristics of at least one of the compartments by surrounding it with additional evacuated compartments. This results in a very minimal gas pressure gradient across the internal walls forming the internal compartment to minimize gas and vapor permeation into it thus greatly enhancing the lifetime of the panel. Further, this permits strategic placing of Bettering materials such that gettering materials absorbing certain gases can be placed in the outer compartments and other gettering materials absorbing different gases can be placed in the internal compartments to enhance the lifetime of the panel.

Granted: 1996-05-07
Abstract: A shared memory multiprocessor having a packet switched bus, together with write back caches for connecting individual processors to that bus, employs a consitency protocol that permits the caches to store multiple copies of read/write data at identical physical addresses for use as neded by the respective processors. The protocol causes the hardware to automatically and transparently maintain the consistency of this data. To that end, the caches detect when a datum becomes shared by monitoring the traffic on the bus, thereby enabling them to broadcast an updating write on the bus whenever their respective processors issue a write to a shared address. If desired, this protocol may be extended to include an advisory invalidate for reducing the amount of address sharing that occurs, thereby enhancing the efficiency of the protocol. The protocol maintains a consistent view of memory for the processors, while permitting I/O devices to have direct access to the memory system.
