Title: Syringes for dental purposes - with gum-freezing device to prevent pain
IPC: A61M5/32
Filed: 1972-11-21
Abstract: Syringe comprises a principal body which houses a sliding piston and a movable needle, for injecting a liq. contd. in a capsule. A 1st manual control serves to project the needle towards the outside of the body. Another independent control can operate simultaneously or not with the 1st control; it is intendent for injecting a refrigerating fluid, from a reservoir in the syringe, on to the gum to be punctured, so as to render the area insensitive and the penetration of the needle painless. Anaesthetization is effected at a precise point without touching any sensitive areas. The angle of penetration of the needle is maintained constant w.r.t. the axis of the tooth. In use, the 2nd control is operated to project the freon on the gum; the tip of the needle, in its armed position, is then used to inject a drop of the anaesthetic into the gum. The needle tip is withdrawn and the end of the syringe placed on the gum at an angle of 40 degrees; the trigger is pulled, the needle pushed forward and the injection performed. The needle is guided in its movements by the tip of the syringe.

Patent FR-2178007-A1 (FR)
IPC: H01L21/60
Filed: 1973-03-26
Abstract: 1377601 Semi-conductor devices SIGNETICS CORP 6 March 1973 [27 March 1972] 10881/73 Heading H1K A semi-conductor body 21 of, e.g. doped silicon having one conductivity type is diffused or ion implanted with dish shaped regions of opposite conductivity extending to its planar surface to define emitter and collector regions with the body as base, and diode or resistor regions forming part of an integrated circuit. An insulant layer 23 of, e.g. thermally grown SiO 2  is formed on the surface in which windows are opened to expose the surface on to which metal, e.g. Al is evaporated to contact the several regions. The metal is removed using photolitho masking to leave adherent leads integral with Al pads 26 spaced round the periphery of the body; the leads extending inwardly from the pads to contact the several regions of the device. A glass layer 28 is deposited over the SiO 2  layer and the leads, in which windows are opened to expose portions of the pads by photoresist masking and etching with HF + ethylene glycol + H 2 O, after which the photoresist is removed. After alloying thermally, a further layer 31 of, e.g. Al is deposited on the glass layer to extend into the openings, and a layer 32 of, e.g. Cr is evaporated thereon as a barrier. A layer 33 of, e.g. Ni is deposited on the Cr by evaporation (Fig. 5). A photoresist mask with windows overlying the pads 26 and their openings is formed on Ni layer 33, and stand off pillars 37 of, e.g. Ni are formed therein, e.g. by electroplating to serve as spacers between the surface and the external leads. A layer 38 of, e.g. Au, a layer 39 of, e.g. Sn, and a further layer 41 of, e.g. Au are electroplated in sequence on the pillars, and the photoresist is removed by solution. A further photoresist layer 43 is formed over the structure (Fig. 12) to underlie the head of the pillars, is baked and is selectively exposed to light, so that after development and solution a band of photoresist remains underlying the pillar head to protect the exposed Sn and Ni layers. The exposed parts of the Ni and Cr layers 33, 32 are electrolytically etched out in H 3 PO 4  with the semi-conductor body as anode, and the exposed Al layer 31 is removed by etching in hot H 3 PO 4  with a foaming agent to limit undercutting. The photoresist band is removed by solvent and the complete device (Fig. 16) is washed and dried. Plural discrete standoffs are connected to pads 26 of the interconnecting leads of the integrated circuit (Fig. 17, not shown). The device is bondable to lead frames of the kind described in Specification 1,359,698 fabricated of Sn plated steel by opposing the frame to the tops of the standoffs in proper alignment and soldering with a gas jet, (Fig. 18, not shown).  The assembly may be plastic encapsulated as described in Specification 1,359,698, or enclosed in a package of glass or ceramic.

Title: Bowling pin clearance appts. for bowling alleys - wiper descends quickly from rest position by electro-magnetic drive
IPC: A63D5/08
Filed: 1974-12-27
Abstract: The apparatus pushes the bowling pins to one side after they have been played. The pushing wiper blade is above the pins in its rest position, but descends to push the pins along to one side. The wiper blade is guided along rails. At the end of its sweep it is raised up again and returns to the first position. So that no pins can roll under the wiper blade it is driven by an electro-magnet. This also speeds the operation cycle and reduces the changes of faults arising. The played bowls can be made to interrupt the light beam of a photo-electric cell arrangement in order to operate the wiper and electro-magnet at the appropriate time.
