Title: Apparatus and method for differential thermal analysis
IPC: G01N25/48
Filed: 1968-09-17
Abstract: 1,240,897. Electric differential thermal analysis. NATIONAL INSTITUTE FOR METALLURGY. Sept.17, 1968 [Sept. 21, 1967], No. 44043/68. Heading G1N. In differential thermal analysis, the temperatures of a test substance and a reference substance are varied at the same rate and the temperature of the test substance, the temperature difference between the substances and the difference in power consumption between the substances are recorded. Any desired gap may be set between the temperatures of the two substances and this gap may be adjusted so that onset of crystallization occurs simultaneously in both substances. As shown in Fig. 2, the reference and test substances are located at the junctions of reference and test thermocouples 76 and 80 respectively. Heating current is supplied to the thermocouples 76, 80 during positive half cycles of an A.C. supply 32. The heat supplied to the reference thermocouple 76 is controlled by an S.C.R. 38 whose firing angle is controlled by a programme unit 40 and the heat supplied to the test thermocouple 80 is controlled by an S. C. R. 48 whose firing angle is controlled in dependence on the difference between the e. m.f. s of the thermocouples 76, 80, which is measured during the negative half cycles of the A.C. supply. Vacuum sealed thermocouples 44, 52 are connected in series with the reference and test thermocouples respectively and the difference between the e. m. f. s of the vacuum sealed thermocouples is amplified during negative half cycles and recorded as the difference in heat consumption between the substances. Also during negative half cycles synchronous contacts connect the e.m.f. of thermocouple 80 and the difference between the e.m.f.s s of thermocouples 76 and 80 to the recorder 30. In another arrangement, Fig. 5 the firing angles of the heat controlling S.C.R.s 38À1, 48À1 are controlled so as to keep the e. m.f. s of the reference and test thermocouples equal to that generated by a programme unit 284. An adjustable source 290 allows any desired temperature difference between the substances to be set. Hall generators 44À1, 52À1 are used to measure the square of the heating current. Heat shields. The reference and test thermocouples may be shielded to avoid heat losses by heating filaments (272, 274) maintained at the same temperatures as the thermocouples by S. C. R.s (280, 282).

Abstract: 1,020,196. Stapling machines. J. KIHLBERG. Oct. 28, 1964 [Oct. 29, 1963], No. 44045/64. Heading B4C. A method of driving, by compressed air, the piston 25 of a tool for driving fasteners such as staples, nails or the like comprises a valve 10 adapted to control, via a passage 11, the supply and discharge of the air leading to a cylinder 23 such that during all the time the compressed air is supplied to the upper pressure surface of the piston for effecting its working stroke, part of the air is utilized for building up an air pressure in a chamber 14 in order that, upon movement of the valve to connect the passage with an outlet port 8, the piston is returned to its starting position. Compressed air is fed into the tool via an inlet 5 and chamber 6 so as to normally maintain the head 44 of the valve into contact with its seat 47 thereby preventing the air passing via the passage 11, into the cylinder. To actuate the tool a trigger 19 is raised so as to depress a plunger 51 which, via a spindle 56, lifts a ball valve 57 off its seat 53 thereby admitting air through a passage 59 and ports 60, so as to act on a piston connected to the head and thus lift the latter from its seat as shown. Air then passes through the passage 11 and into the cylinder 23 to drive the piston 25 downwardly, air simultaneously entering the chamber 14 via a restricted port 15; the port may be replaced by an adjustable nozzle. When the piston 25 reaches the end of its working stroke and the trigger released, the compressed air in the chamber 14 passes through a port 20, and annular space 31 to act on the bottom face 31 of the piston so as to rapidly return it; air above the piston is exhausted via the passage 11, past an O-ring seal 46 on the valve 44, annular space 8 and passage 9. A magnet 21 is provided in order to retain the piston 25 in its inoperative position.

Abstract: 1,205,247. Carrying handles. WINDMÍLLER & HÍLSCHER. 29 Sept., 1967 [20 Oct., 1966; 14 Jan., 1967], No. 44515/67. Heading A4G. [Also in Division E2] Two thermoplastics handles 20, 25 for a thermoplastic sheeting carrying bag 7, each comprising a handle grip portion and a strip 32 heat-sealable to the bag edge, are formed as a single unit by injection moulding so that the two strips are connected side by side by a 0.1 mm thick web 49 that may be at each end of the strips, or disposed at intervals along the length of the strips with either a thicker web at each end or web-free ends. The web(s) may be perforated so that after the handles have been folded together, Fig. 14, and the strips sealed to the bag the web(s) may be easily broken to open the bag. The thicker webs at each end may remain unbroken to prevent the bag edges from tearing too. Snap fasteners flush with the surfaces may be provided to hold the bag closed, the male members being on one handle at its base, and the female on the other, each surrounded by a thinned area to act as a diaphragm. In another embodiment, Fig. 12, a flap 21, attached to one handle grip 20 by a thinner strip, folds under the handle grip portions and round the other handle grip 25, optionally closing with a snap fastener 23; a projection 27 on the flap facilitates release of the fastening.

Title: A forced flow once-through vapor generator and method for starting the same
IPC: F22B35/14
Filed: 1963-11-12
Abstract: 1,005,172. Forced flow steam boilers. COMBUSTION ENGINEERING Inc. Nov. 12, 1963 [Nov. 20, 1962], No. 44583/63. Heading F4A. A method for starting a forced-flow oncethrough vapour generator, having means for recirculating heated fluid through the vapour generating section, comprises initially maintaining a liquid level in a primary superheater and thereby obtaining low pressure vapour. In starting a vapour generator comprising economizer 20, vapour generating tubes 24, boiler throttling valves 56, 57, convection superheater 32 and finishing superheater 36 arranged in series together with turbine 40, condenser 14, feed pump 12 and feed valve 18 and having a recirculating circuit 46 containing valve 52, a mixing vessel 48 and a pump 50 for recirculating fluid through the tubes 24, fluid is first pumped through the economizer 20 and tubes 24 and, with valves 56, 57 closed, discharged through a boiler extraction valve 55. When this cleaning operation is completed valve 55 is closed or set to open at a predetermined high pressure, the furnace is fired and when a given pressure is reached valve 18 is closed and liquid is recirculated through tubes 24 to maintain a minimum safe velocity through them. When a given temperature, determined at a point such as 72, is reached, valve 57 is gradually opened by an actuator 62 permitting fluid to flow into superheater 32 which is maintained at a low pressure by a relief valve 75. Some of the fluid vaporizes, cooling the final superheater 36 whilst the remainder establishes a liquid level 58. When a suitable pressure and temperature has been reached as indicated by devices 74, 76, a turbine flow control valve 42 is opened permitting vapour to commence heating and rolling the turbine. Valve 57 is then controlled, to maintain the level 58, by a pressure differential indicating device 60 connected hydraulically or electrically to pressure sensing means 64, 66 until as the temperature in the vapour generating portion rises and normal operating conditions are approached the liquid level 58 falls until no liquid remains in the superheater 32 and the pressure drop across valves 56, 57 as indicated by devices 73 becomes negligible when these valves are fully opened.

The pusher 5 has at one end a head 35 adapted to fit in a through slot 26 of a head portion 19 of the staple housing, which slot has side walls 27 which holed by means of "L"- shaped grooves 28 lugs 54 of a staple cartridge 3. At the opposite end, the pusher 5 has a handle 8 with a screw 37 extending therefrom engaged by a cylindrical nut 7 which has a handle 44 pivotally connected thereto at 43, and an annular groove 42 which engages with a yoke 22 extending downwardly from the staple housing 4. This end of the staple housing terminates in a screw 21 carrying a nut 6 which has an annular groove 40 which engages with a yoke 17 at the end of the support body 1. A limiter 9 which is to hold the tissues against the anvil in the form of a bent strip is slidably mounted on the housing 4. In the operation of the instrument the tissues to be stitched are placed between the jaws 2 and the magazine 3 and closed in this space by bringing the limiter 9 up to the jaw. The nut 7 is turned to bring the staple housing with the magazine 3 and pusher 5 up to the tissues. The handle 44 is moved from its non- working position (in full lines on Fig. 3) to its working position (dotted lines). On turning handle 44 about its axis the head 35 of the pusher forces out the staples from the magazine through the tissues and with the help of recesses of the anvil 2 the staples are converted into stitches. An abutment 38 on the pusher moving in an aperture 30 in the staple housing limits its extreme working position relative to the staple housing. The instrument may be adapted to staple with a lateral arrangement of stitches, Fig. 3 (45), 16, or with an offset double row parallel to the longitudinal direction of the magazine, Figs. 10-15 (not shown). For the first arrangement the cartridge 3, which is of the form of a frame with an aperture 51 with paired grooves 57 which hold the staples (not shown) horizontally, is -fitted on to the pusher head 35. In the latter arrangement the pusher head 63 has plates 68 fixed thereto which push the staples from two offset rows of vertical windows 71.
