Patent GB-399110-A (GB)
Title: Process and apparatus for the preparation, with or without pressure, of hydrogen
IPC: C01B3/06
Filed: 1933-03-29
Abstract: In the alkali-silicon process for generating hydrogen, powdered silicon is mixed dry with powdered, flaked, or granulated caustic soda, the mixture added to water in an autoclave and the device closed.  The reaction commences in a few minutes and proceeds to completion very rapidly with the formation of sodium acid silicate. In a modification, the water may be added to the mixed reagents or these may be added separately without previous mixing. The violence of the reaction may be mitigated by omitting the dry mixing, by using a larger amount of cold water, by employing the reagents in a less finely divided form or by external cooling. In another modification, the process is carried out at normal pressure by adding a high boiling liquid, such as a mineral oil, a layer of which used to cover the surface.

Title: A measuring device for stationary and portable machines for boring engine and the like cylinders
IPC: G01B5/00
Filed: 1936-04-04
Abstract: 461,052. Boring-machines. KELLENBERGER, L., (trading as KELLENBERGER & CO., L.) April 4, 1936, No. 9986. Convention date, April 5, 1935. [Class 83 (iii)] In a machine for boring engine cylinders a device for measuring the bores of the cylinders is incorporated, comprising a spring loaded feeler pin radially mounted at the end of the tool spindle to contact with the cylinder wall and acting on a rod extending axially through the spindle, the movements of the rod being transmitted by a lever to a second rod outside the spindle and connected to an indicating device arranged in a convenient position. As applied to a stationary machine a vertical slide 1, Fig. 1, carries a boring spindle 2 mounted in a bearing 3 and provided with a tool head 4 and cutter 5. The feeler pin 6 is pressed radially inwards by a spring 7, Fig. 2, against a lever 8 which engages the rod 9 passing axially through the spindle. A spring 12 balances the weight of the rod 9 and a further rod 13 is pressed down against it by a spring 14. A lever 16 pivoted at 17 on a bracket on the slide 1 has ball ends 15 engaging the rod 13 and a rod 18 slidable in a guide 19 in the slide 1. A spring 20 presses the rod 18 upwards and the lower end of the rod engages the pressure pin 22 of an indicating device 21 on the slide, arranged adjacent the boring head 4. In operation, the cutter 5 is retracted and the pin 6 withdrawn by lifting the rod 9 &c. through a pin 10 attached to the rod and passing through a slot in the spindle, thereby allowing the boring head to be inserted in a cylinder 23. The pin 6 is then allowed to contact with the cylinder wall and the cylinder is centred with respect to the spindle, measurements being taken at different depths so as to average the amount d, Fig. 2, to be removed by the cutter according to the greatest amount of wear b in the cylinder. The pin 6 follows the cutter during boring so as to indicate the correctness of the operation. The rod 9 is a fixture in the spindle 2 so that when changing the latter for one of different length there is no necessity for adjusting the rod 13. As applied to a portable machine for attachment to the work, the spindle 25, Fig. 4, carrying the interchangeable head 24 is rotatably mounted in a vertically sliding sleeve 26 fed by a screwed spindle, (not shown). A single rod 29 passes axially through the spindle 25, the pressure of a spring 30 and the weight of the rod acting against the pressure of the spring 7 to maintain the pin 6 against the cylinder wall 34.

Title: Process for producing 4-amino-6-fluor-chromane-4-carboxylic acid and its /2r/-methyl ester
Inventor: URBAN FRANK J
IPC: C07D491/107
Filed: 1985-08-17
Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate  beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with  alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.

Title: Alignment mark for mutual alignment of two objects
Inventor: PAURU KAIZAA
IPC: G01B11/00
Filed: 1991-01-09
Abstract: PURPOSE: To reduce the positioning error due to the mutual optical influence by placing straight lines directly superposed on one aligning mark region in parallel at specified positions; the aligning marks are composed of parallel straight lines. CONSTITUTION: To scan a mask in the horizontal x-axis direction, evaluating regions 3M, 2M are scanned to obtain an xM signal by the integration of their brightness values in the vertical direction. Evaluating regions 1M, 4M of a mask are scanned to obtain a yM signal in the vertical y-axis direction. This can attain a high line resolution in the optoelectronic evaluation and thus it is possible to obtain a high line density to increase the information of the aligning marks.

Abstract: PURPOSE:To make carriers photosensitized and generated by optical irradiation of a photoelectric conversion element respond at high speed by giving electrodes on the lower side and upper side of a semiconductor the same shape and size as the semiconductor. CONSTITUTION:A first conductor 2, a photosensitive semiconductor 3 and a second conductor 5 are laminated on a heat-resistant light-transmitting substrate 1, patterning is conducted by using a mask (1), and an organic resin 6 such as a photosensitive polyimide resin is formed on the whole surface. When pre- baking is performed and the back side of the glass substrate 1 is exposed by ultraviolet beams 15, the organic resin in the upper section, which is shaded to a laminate 10, of the laminate 10 is not photosensitized, and only the organic resin in the side periphery of the laminate is photosensitized. The side periphery of the laminate can be filled with the organic resin without using a photo-mask at all, thus univocally determining the shape and size of a semiconductor and a lower electrode on the lower side from a shape on the upper side of the laminate. Accordingly, the upper and lower electrodes can be brought to the same or approximately the same shape and size as compared with the semiconductor.
