Title: Needle retraction mechanisms
Inventor: MCMAHON KEITH HERD YOUNIE
IPC: A61M5/50
Filed: 1995-08-10
Abstract: PCT No. PCT/GB95/01894 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Aug. 10, 1995 PCT Pub. No. WO96/05879 PCT Pub. Date Feb. 29, 1996A fluid handling device has a needle retraction assembly which brings about the retraction of a hollow needle after use. A hollow body portion is provided at one end, with an end wall having a mounting portion including a needle passage. A hollow needle having a leading end portion is movable between a first position in which the leading end portion of the needle protrudes from a front end portion of said mounting portion and a second position in which the needle is withdrawn within the hollow body portion. A spring acts to bias the needle into the second, withdrawn position. The needle is provided with a portion of enlarged diameter at a location spaced from the leading end portion. A retainer maintains the needle in its first position until use is completed. The retainer includes an O-ring positioned in a circumferential groove in the portion of enlarged diameter. The O-ring abuts the end of a sleeve slidable within the mounting portion and which can be forced forwardly to dislodge the O-ring so as to permit the needle to move from its first position into its second position under the influence of the spring.

Title: Audio amplifier with reduced quiescent current - has balanced output stage fed by emitter follower and constant current source
IPC: H03F/
Filed: 1976-01-16
Granted: 1981-11-30
Abstract: Audio amplifier with improved facility for reducing the quiescent current. This ensures a stability and reduces distortion and noise to a minimum. The amplifier integrated circuit consist of a complex semiconductor device operating in conjunction with an external circuit. The final stage of the amplifier contains a balanced output, and consists of an emitter follower control state receiving audio signals at a reasonable level from a source (10). The source is connected to the base of the control transistor connected to the positive line (12) of the supply and to earth via a loading resistor. There is a common and a separate connection to the current supply source. The active surfaces of the two output transistors are approximately the same with identical conductivity. The control stage consists of a third transistor which feeds the balanced output.

Patent IT-1163207-B (IT)
Inventor: VEZZANI LUCIANO
IPC: B30B9/32
Filed: 1983-03-31
Granted: 1987-04-08
Abstract: To compact such scrap materials as relatively comminuted chip, waste, and the like, an apparatus is provided which comprises a vertically extending briguetting machine, upstream whereof there is provided at least one horizontal pre-compression device. The briquetting machine has a portal-like configuration and a vertical compacting ram arranged to penetrate a side intake feed chamber and a vertical axis die. A closure anvil is movable under the die. The die is mounted with a small clearance in the die holder and has an indentation along one generatrix of the outer surface. Thus, the die will be ruptured along the generatrix line during the compression stroke. This does not jeopardize functionality but rather makes die replacement easier. The vertical arrangement eliminates eccentric wear as due to the weight of the horizontally moving elements of known briquetting machines, and facilitates the intaking of the pre-compressed material.

Title: Crosslinked cyanic ester based resins - for use in foams, moulds, electrical industry, pipes vehicles etc.
IPC: C08G/
Filed: 1977-05-06
Granted: 1985-05-08
Abstract: Synthetic resins are prepd. by a process in the first stage of which prepolymers, partly crosslinked but still sol. in org. solvents, are formed by reaction between aliphatic polyhydroxylic cpds. and cyanic esters that are di- or polyfunctional at 30-250 degrees C. The prepolymers are then hardened by heating to 100-350 degrees C and/or by reaction with polyisocyanates and, possibly, cpds. contg. gps. reactive to isocyanates. Soluble prepolymers, stable at room temp., contg. OH gps. and triazine rings, iminocarboxylic acid ester gps. and in the latter case, free CN gps, are obtd. by reaction in the mass or in soln., with aliphatic polyhydroxy cpds. and di- or poly-functional cyanic esters at 30-250 degrees C. The cross-linked resins are partic. useful in prepn. of foams and, when they contain granular materials (e.g. aluminium, chalk) or strengtheners (e.g. glass fibre in various textile foams), in prepn. of moulds and tools; in the construction of light weight vehicles subjected to containing forces, as well as in aerial and space travel; in the electrical industry; and in the mfr. of pipes and cisterns.

Title: Air cooling device for prevention of yarn melting - when stopped in high temperature texturing jet
IPC: D01D/
Filed: 1974-04-23
Granted: 1980-02-29
Abstract: Stoppage of yarn in the jet due to a process interruption is sensed by a device which operates a valve to allow high pressure air to flow across the yarn entry slot via an orifice positioned opposite the entry, the high temp. steam is thus diverted out of the jet through the yarn entry and away from the yarn. The need to remove jets for cleaning after process stoppages can be reduced from 15 to 3% of the stoppages, thus reducing down time on the affected portion of the machine.

Title: Feed measurement for cylinder block milling - has preproduction workpiece processed at constant feed to measure average cutting resistance
Inventor: DAPIRAN A
IPC: G05B/
Filed: 1975-11-19
Granted: 1981-03-20
Abstract: The series processing of workpieces on a machine tool ensures a constant feed speed for each workpiece over the total transport distance and is esp. for milling cylinder blocks. Before machining the series of workpieces at least one preproduction part is processed at constant feed speed on the machine tool. For each such part the values of the patterns of cutting resistance are determined over the feed lengths. The average resistance value is stores and the production workpieces are then machined. the feed speed of the tool is controlled on the basis of a combination of parameters of which a first is a factor which decreases in a predetermined relationship to the increase in cutting resistance met by the tool. A second is proportional to the first factor and influences the feed speed opposite to the first parameter.

Title: Chestnut roasting and stripping equipment
Inventor: COLOMBINI SERGIO ROBERTO
IPC: A23N/
Filed: 1984-11-09
Granted: 1987-09-30
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.
