Abstract: APPLICANTS:    (1) EKA AB                (2) G?RAN BENGTSSON (3) RUNE SIMONSON          TITLE:         A METHOD OF MANUFACTURING BLEACHED CHEMI-MECHANICAL AND SEMICHEMICAL FIBRE PULP BY MEANS OF A TWO-STAGE IMPREGNATION PROCESS     ABSTRACT OF THE DISCLOSURE        Chemimechanical pulp is produced from ligno-cellulosic material in a process in which the material is impregnated in two stages. The material is treated in the first stage with alkaline and, subsequent to passing an intermediate draining and reaction step, in the second stage with a solution that contains per-oxide. The quantities of alkali and peroxide charged are fully optional and are independent of one another. The material is then optionally subjected to a further drainage and reaction step, and thereafter pre-heated at a temperature of between 50°C and 100°C, where-after the material is refined in one or two stages.   The optimal brightness of the processed pulp for a given peroxide consumption is achieved by a balanced division of the peroxide charge between chip impregnation and bleaching.

Title: Foamable explosive combinations
Inventor: SHANN PETER C
IPC: C06B47/14
Filed: 1986-05-06
Granted: 1992-10-20
Abstract: Abstract The invention relates to a foamable explosive combination comprising a so called "liquid" explosive, conveniently an oxidizing salt or salt-saturated aqueous composition, with a low boiling point liquid dispersed through the combination.  The low boiling point liquid is selected to maintain its liquid form at normal temperature and elevated pressure and to vaporize at atmospheric temperature and pressure.  When packaged in a container part of the low boiling point liquid, or a second low boiling point liquid, vaporizes to maintain at least part of the first low boiling point liquid in liquid form within the combination and in such a state the combination is stable and has a relatively long shelf life.  When the combination is released from the container to atmosphere the low boiling point liquid in the combination vaporizes to foam the combination. The combination may also include metals, such as aluminum, or solids explosive materials in finely divided form.

Abstract: METHOD AND APPARATUS FOR FACILITATING INSTRUCTION           PROCESSING OF A DIGITAL COMPUTER               ABSTRACT OF THE DISCLOSURE           A computer having a cache memory and a main memory is provided with a transformation unit between the main memory and the cache memory so that at least a portion of an information unit retrieved from the main memory may be transformed during retrieval of the information (fetch) from a main memory and prior to storage in the cache memory (cache).  In a specific embodiment, an instruction may be predecoded prior to storage in the cache memory.  In another embodiment involving a branch instruction, the address of the target of the branch is calculated prior to storing in the instruction cache.  The invention has advantages where a particular instruction is repetitively executed since a needed decode operation which has been partially performed previously need not be repeated with each execution of an instruction.  Consequently, the latency time of each machine cycle may be reduced, and the overall efficiency of the computing system can be improved.  If the architecture defines delayed branch instructions, such branch instructions may be executed in effectively zero machine cycles.  This requires a wider bus and an additional register in the processor to allow the fetching of two instructions from the cache memory in the same cycle.

The handpiece and nose cone assembly have mating passageways for aspiration and irrigation, and the handpiece supports a laser energy transmitting tube that is releasably received in the nose cone assembly.  The nose cone assembly comprises an outer housing, an inner housing located inside the outer housing,  and an aspiration tube located inside the inner housing.  The outer and inner hous-ings and the aspiration tube have coaxially aligned lateral openings defining a photovaporization chamber.  The distal end of the laser energy transmitting tube is located adja-cent the photovaporization chamber. In use, tissue to be removed  is  aspirated  into  the  photovaporization  chamber where it is vaporized by the laser energy and then conducted along the aspiration tube.  Irrigation fluid flows between the outer and inner housings and then out the end of the outer housing  to  cool  the photovaporization chamber  and replace the tissue volume removed from the eye.  Preferably, the laser energy transmitting means is a fiber optic rod with a lens fused on the end to direct the laser energy into the photovaporization chamber and thus prevent it from being scattered into the eye.  Nose cone assemblies of different configurations can be releasably coupled to the handpiece and exchanged during surgery.

Title: Slide block feed apparatus for a press utilizing an oscillating cam
Inventor: GENTILE JOSEPH P
IPC: B65H20/18
Filed: 1987-12-04
Granted: 1991-09-10
Abstract: ABSTRACT           A cam shaft of a press feed having a  first  pair of cam surfaces is rotated at a preselected speed depending upon the speed of the press.  Continuous  rotation  of  the cam  surfaces  is  converted  to  intermittent  oscillating rotational  movement  of  an   output shaft   through   a preselected  angle  of rotation by a pair of cam followers.          The cam followers are nonrotatably connected to  an  output shaft  that is connected by an adjustable linkage mechanism to a slide block.  The intermittent oscillating  rotational movement  of  the  output shaft is transmitted to the slide block to advance the slide block containing stock  material such  as  a  bar  or  wire  through  a preselected distance corresponding to  a  preselected  feed  length.   The  feed length  is  adjustable  by changing the length of travel of the  linkage  mechanism  with  respect  to  the  degree  of rotation  of  the  output  shaft.   The  slide  block moves horizontally through  a  preselected  distance  to  feed  a prsselected amount of material, remains stationary during a first  dwell  period  and  releases  the  material,   moves horizontally  in the opposite direction back to the initial feed position, remains stationary for a second dwell period and  engages  the  material  for  another  feed cycle.  The intermittent  feeding  operation  of  the  slide  block  is coordinated  with  the  operations  of  releasing the slide block and clamping  the  stock  material  with  a  separate material  clamp  for  holding  the  material  while  it  is released from the slide block.

Abstract: TWIST COIL SPRING BIASED WOBBLE PLATE COMPRESSOR            ABSTRACT OF THE DISCLOSURE       A refrigerant compressor including a compressor housing hav-ing a cylinder block is disclosed. A plurality of cylinders are formed around the periphery of the cylinder block. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mecha-nism. A crank chamber is formed between the cylinder block and a front end plate of the compressor housing. The drive mechanism includes a drive shaft, a rotor disposed on the drive shaft, a slant plate with an adjustable slant angle disposed adjacent the rotor and a wobble plate disposed adjacent the slant plate. The drive shaft is rotatably supported within the front end plate. Rotation of the drive shaft causes rotation of the rotor and the slant plate, causing nutational motion of the wobble plate to reciprocate the pistons within their cylinders. The compressor housing includes a rear end plate defining suction and discharge. A communicating path commu-nicates between the crank chamber and the suction chamber.  A stroke of pistons is changed by adjusting a slant angle of the slant plate. An elastic member urges the slant plate toward minimum slant angle to adjust the slant angle of the slant plate.
