Title: Cam system of a double-cylinder circular knitting machine
Inventor: ZAHRADKA PAVEL
IPC: D04B15/32
Filed: 1988-10-05
Abstract: The latches of needles (5) in the upper cylinder of a double-cylinder circular knitting machine are opened by the tips of empty lower guiding sliders (3) and in the places where upper guiding sliders (4) with the needles (5) are lowered into clearing position there are retracting cams (11, 18) to retract empty lower guiding sliders (3) to a level where their tips are in the tricks of the lower needle cylinder (1), i.e. below the upper level (F) of the trick walls. Engagement between the sliders and the latches therefore takes place within the tricks and this avoids the elements missing one another. <IMAGE>
Patent GB-885900-A (GB)
IPC: D06F71/14
Abstract: 885,900. Ironing apparatus. FREEMAN, D. A. Jan. 14, 1960 [Nov. 13, 1959], No. 1418/60. Class 138 (2). [Also in Group III] Spraying apparatus for spraying a moving member in timed relation with the latter's movements comprises a spraying nozzle disposed in a position to direct spraying medium at the moving member, a power-operated valve which controls the flow of spraying medium to the nozzle, means for controlling energization and de-energization of the power-operated valve, a movable cam arrangement which operates said control means and means coupling the cam arrangement to the movable member for synchronizing movements of the cam arrangement with movements of the moving member. Fig. 1 shows an embodiment for use with a cabinet press 10 for pressing a shirt 17 on a body form buck 13 mounted on a reciprocating movable carriage 14. The carriage runs on wheels 15 on a track 16 parallel to the press heads 12. Piston 23 actuated by operating button 22 strikes a depending member 24 causing the carriage to roll into the cabinet. A spray system 30 operated by a solenoid is provided to damp selected portions of the shirt (buttoning strip, pockets, &c.) and is energized and controlled by a timer 31. The timer is coupled to the carriage 14 by a cable, string or wire 32 wound on a drum 33 forming part of the timer. Thus, as the buck enters the cabinet, the cable winds on the drum and energizes the solenoid-operated valve and sprays selected parts of the shirt. Several modifications of the timer are shown and described.

Title: Safety device for power tools incorporating a chuck
Inventor: ELCOCK GERARD
IPC: B23B45/00
Filed: 1991-05-14
Abstract: A lock-shield (11) is displaceably located within the handle of the power tool and is displaceable between a locked and unlocked state by means of the chuck-key (10) of the tool which engages with a rack (13) provided on the lock-shield so that rotation of the chuck-key (10, 10') displaces the lock-shield into and out of engagement with the trigger or operating switch (16) of the power tool. When the chuck-key is in position in the handle of the power tool and rotates so that the key is retained in the handle, the lock-shield is displaced out of engagement with the operating switch or trigger enabling the tool to be operated. If the chuck-key is rotated to enable such to be removed from the handle of the power tool, then the arrangement of the lock-shield is such that it is brought into engagement with the trigger or operating switch of the tool preventing such from being operated. Spring biassing means (17) is provided for preventing accidental displacement of the lock-shield when the chuck-key is removed, but is disengageable from the lock-shield whenever the chuck-key is replaced in the housing of the power tool. <IMAGE>

Title: Apparatus and method for monitoring laser material processing
Inventor: NING QI
IPC: B23K26/14
Filed: 1991-07-29
Abstract: In the apparatus and method an indication of the quality of the processing is obtained by monitoring the plasma generated spaced charge distribution near the melt pool. A metal electrode (14), or electrodes, is disposed near the melt pool but not in contact with the workpiece (16), nor necessarily in contact with the hot plasma. The electric charge distribution (one dimensional or multi-dimensional) is monitored between the electrode or electrodes and the workpiece or between the electrodes themselves. The existing laser processing nozzle (insulated from the workpiece) can be used for this purpose, multi-probes such as a quadrant nozzle, can identify the focused laser beam position in real time. Such monitoring is applicable e.g to laser welding or drilling. <IMAGE>

Title: Osmotic pumps
Inventor: CHERIF CHEIKH ROLAND
IPC: A61M5/145
Filed: 1991-11-27
Abstract: An osmotic pump comprises a housing 2 within which is a delivery chamber 5 separated from an osmotic salt chamber 7 by impermeable moveable pressure responsive means such as a piston 6 or a flexible membrane. The osmotic salt chamber 7 is separated from a source of osmotic fluid, e.g. an osmotic fluid chamber 12, by a semipermeable membrane 96, optionally mounted in a piston 9. A fluid barrier isolates the osmotic salt chamber 7 from the source of osmotic fluid for storage of the pump, and may be inactivated when the pump is to be used. The fluid barrier may be a foil sheet 10, inactivatable by rupture, or a piston and a fluid bypass arrangement (21, 23, Fig 4). Activation of the osmotic pump may be effected in some embodiments by loading the discharge chamber 5 with the agent to be delivered and in other embodiments by movement of a plunger (16, Fig 7) under manual control or, if the plunger is pre-biassed, by release of a locking means (18, Fig 10a) which holds it in position. <IMAGE>

Title: Packaging food products
Inventor: JONES ARTHUR NEVILLE
IPC: B65D81/30
Filed: 1992-04-03
Abstract: A process for packaging a food product 3 consisting of, or including, a substance having a fat content of at least 25% by weight based on the weight of the substance (e.g. chocolate), comprises enclosing the food product in a package through which the food product is visible from the exterior. The package comprises an inner container 2 which provides a barrier to the passage of oxygen to the food product, and an outer container 1 which provides a shield for the food product from ultraviolet radiation. The atmosphere within the inner container 2 has, at least initially, a relatively low partial pressure of oxygen compared with that in ambient air. An oxygen-scavenger (16, Fig. 3) is arranged, e.g. in an internal tray 9 not in contact with the food product, to decrease, or tend to prevent an increase in, the partial pressure of oxygen within the inner container 2. After opening the package, the outer container 1 can be reassembled to continue to shield the food product from ultraviolet radiation. The oxygen scavenger may be an inorganic, e.g. iron filings, or an organic, e.g. polyester with aromatic nylon substance. When an organic substance is used a metal catalyst such as cobalt must also be used. Preferably the ultraviolet protection may be provided by layers of a polyester and may also include an additive such as benztriazole or benzophenone. <IMAGE>
