Abstract: 1419705 Gas cooling installations VIA GES FUR VERFAHRENSTECHNIK mbH 2 July 1973 [1 July 1972] 31332/73 Heading F4S A gas (e.g. air at 35‹ C.) is dried by cooling it in an interconnected pair of upright heat exchangers 12, 14 wherein the gas flows firstly through the heat exchanger 12 (in which it is cooled by outgoing gas), then through the heat exchanger 14 in which it is cooled by a refrigerant flowing, e.g. in tubes 44, and finally back again through the heat exchanger 12 wherein it cools the incoming gas. As shown the gas path in the heat exchanger 12 is from an inlet 28, and vertically downwardly (direction m) over finned cooling tubes 24 to an outlet 30. Any liquid condensed out of the gas is removed at 58. From the outlet 30 the gas flows to an inlet 40 of the heat exchanger 14 wherein the gas is cooled as it descends over refrigerant coils 44 (e.g. sinuous tubes, Figs. 3, 4, 5). Any liquid condensed out of the gas at this stage is removed at 57. The cooled gas then passes back into the heat exchanger 12 via connections 42, 32 and a filter 56. In the heat exchanger 12 the cooled gas now flows generally upwardly in a sinuous path (as directed by baffles 20) through finned tubes 24 in which the cooled and dried gas en route to the exit 34 is warmed to about 20‹ C. by the incoming gas flowing over the tubes (direction m) from the inlet 28.

Abstract: 1,219,445. Valves. GOTAVERKEN, A.B. 2 July, 1968, No. 31443/68. Heading F2V. [Also in Division G3] A valve (9) for controlling the signal pressure to a diaphragm-operated diesel engine speed governor (3) has a first valve member 18 movable into and out of bore 13 by a spring-loaded diaphragm 20 under the influence of signal pressure in conduit 8 and a second valve member 19 urged on to its seat by a spring 25 and moved thereoff by abutment with the first valve member when the latter has moved sufficiently into the bore 13. Conduit 10 which is at first in communication with conduit 8 via open valve 18 is thus cut off from conduit 8 for a pressure range (corresponding to undesirable engine revolutions) the limits of which are defined by the closing of valve 18 and the opening of valve 19 which reconnects the two conduits 8, 10 to equalize the pressure therein. The signal pressure is controlled by a manually-operated pressure regulator (7) and is inversely proportional to engine speed. A directly proportional arrangement may be used to control the engine and a number of valves (9) each cutting off communication between conduits 8, 10 over a different pressure range may be used.
Patent GB-768039-A (GB)
Title: Improvements in indexing mechanism for machine tool and like tables
IPC: F16D71/02
Filed: 1954-11-01
Abstract: 768,039. Machine tool details; indexing. SCHOLIN, H. W., and SCHOLIN. C. W. Nov. 1, 1954, No. 31471/54. Class 83 (3). Indexing apparatus comprises a plate or table 23, Fig. 2, rotatable about a fixed pivot 40 and having mechanism for indexing it contained in a casing 21, Fig. 3, having wings 27 for attachment to a support such as a machine-tool structure. The table 23, Fig. 2, carries a number of pins 48 around its edge which extend above and below the plate and are equally spaced according to the number of indexed positions required. Any form of work-support may be secured to the plate and the upper ends of the pins 48 may be used as locating dowels for such supports. The lower ends of the pins are used in the indexing mechanism. A latch 52, Fig. 3, pivoted at 53 to the casing has a slot 55 which engages a pin 48 to hold the plate in an indexed position. The latch 52 is connected at 57 to a link 58, Fig. 6, which is in turn pivoted at 60 about a pin secured to a quadrant 42 rotatable about the central axis of the device. The indexing movement may be performed by hand by pushing a rod 68, or may be fluid-operated by a piston 103. Alternatively, the indexing and return of the mechanism may be effected automatically by a single electric switch. As described, the piston 103 pushes the rod 68 which carries a pin 66 engaging a slot 65 in a quadrant 43 which lies under the quandrant 42 and is also rotatable about the central axis. As the quadrant 43 rotates clockwise, a connecting-link 70 pivoted to it at 69, rotates a dog 72, an opening 77 in which is brought into engagement with one of the pins 48. The dog 72 is pivoted at 73 to a spacing-piece 74 on a third quadrant 44 which is again rotatable about the central axis of the device and underlies the quadrant 43, Fig. 2. A projection 85, Fig. 9, on the dog 72 engages an end-piece 59 on the link 58 and withdraws the latch 52 at the same time as the dog 72 engages the pin 48 (D-1). Further rotation of the quadrant 43 rotates the table, and plates 43, 44 are automatically locked together to move into the newly indexed position, Fig. 6. Quadrant 44 engages a stop-piece 91 in this position and a projection 102 engages a contact 101 to operate a switch-and-solenoid gear to reverse the fluid-supply to the piston 103. On reverse movement of the quadrant 43, which is now disengaged from quadrant 44 (held against rotation for a short interval), a cam-piece 100, Fig. 6, on the dog 72 pushes a guided link 62 pivoted to the quadrant 42 by a pin 61 and rotates the quadrantnticlockwise to engage the latch 52 with the newly-positioned pin 48 adjacent thereto. Thus the plate 23 is held while the dog 72 is released and returns with the other parts of the mechanism to the original position shown in Fig. 3. In this arrangement a valve 109 is operated by an adjustable stop 112 in lieu of the switch operated by the projection 102.

[Class 146 (iii)] To facilitate the sharpening of a lead, more particularly with a chisel point a grip 10 of a pencil holder is provided with pairs of inclined facets 21, 22 so that when the lead 12 and the facets are successively rubbed on a flat abrasive surface, corresponding facets are produced on the lead. The grip 10 is slit at 14. When inclined surfaces 15 on the grip 10 are clamped by similarly inclined surfaces 9 on a ferrule 8 secured to a casing 7, the grip 10 clamps the lead 12. The grip 10 is extended by an extension 13 screw-threaded at 17 for co-operation with a threaded recess 20 in a rod 18 having a milled head 19 rotation of which varies the clamping pressure exerted by the grip 10. In modifications, Figs. 7 - 15 (not shown), the ferrule 8 is internally threaded for engagement with threads on the extension 13 which is hollow to provide a storage space for leads. In a further modification, Figs. 16 18 (not shown), the grip may be clamped by a clamping bolt secured to one jaw by a transverse pin and through which the lead passes, a nut being provided on the bolt to adjust the clamping pressure.

Title: O-methyl-l-tyrosyl amides and acid addition salts thereof
IPC: C07C233/00
Filed: 1955-11-04
Abstract: The invention comprises O-methyl-L-tyrosyl amides of the general formula: <FORM:0795286/IV (b)/1> (wherein R1 and R2 are hydrogen atoms or hydroxyalkyl, aralkyl or cycloalkyl radicals, or jointly form with the nitrogen to which they are linked a heterocyclic radical) and their acid addition salts, and the preparation thereof by treating O - methyl - N - phthalyl - L - tyrosine with a halogenating agent in the presence of an organic solvent, condensing the resulting acid halide with ammonia or a primary or secondary amine, subjecting the resulting O-methyl-N-phthalyl-L-tyrosyl amide to hydrazineolysis under acid conditions to remove the phthalyl group and, if desired, adding alkali to liberate the amide from the resulting salt thereof.  The halogenating agent may be a phosphorus halide (e.g. PCl5, PCl3, PBr5 or PBr3) in the presence of, for example, ether, dioxan, dimethyl-formamide, ethylene glycol, dibutyl ether or acetone; the amination is advantageously effected at a temperature from -10 DEG  C. to the boiling point of the reaction mixture (preferably 0-25 DEG  C.), in an inert non-acidic solvent (e.g. chloroform, dioxan, ether, lower alkanols, dimethyl formamide or tertiary amines), preferably in the presence of a base (e.g. NaOH or KOH) to bind the haloacid liberated.  Hydrazineolysis may be effected with hydrazine hydrate (preferably in b -methoxyethanol) or with a substituted hydrazine, in the presence of a mineral acid (e.g. HCl or H2SO4) or an organic acid (e.g. formic, propionic or especially glacial acetic), whereby the corresponding salt of the amide is formed; other salts specified are phosphates, tartrates, malonates, succinates, citrates and glutarates. Examples describe the preparation of O-methyl-L-tyrosine benzylamide, amide, b -hydroxyethylamide, morpholide and cyclohexylamide.  Other meanings specified for R1 and R2 are hydroxymethyl, a - and b -hydroxypropyl, a - and b -hydroxybutyl, and 3-methyl-, 4-ethyl-, 3-methoxy-, 4-ethoxy- and 2-chloro-cyclohexyl, and, jointly with the nitrogen atom, piperidino and pyrrolidino.  The products are useful as antibacterial and antiprotozoal agents.

Abstract: 759,726. Starting. PULS, E. Nov. 2, 1954 [Nov. 7, 1953], No. 31669/54. Class 7(5). [Also in Group XII] In a engine starting device comprising a charge 14, 18 of nitro-cellulose in a chamber 9 communicating with the engine through a passage 4 controlled by a valve having a coned head 1 and a shank portion 3 of larger cross section than the head, the shank passing through a seal, and a valve spring 2 exerting a pressure greater than that of the normal engine combustion gases acting on the head 1, the gases from the ignited charge impinge on the differential cross-section between the valve head 1 and shank 3, whereby the valve opens when the pressure thereon is greater than that exerted by the spring. A normally closed rotary valve 7 is manually opened and an ignited match is dropped through the bore 12a in a headpiece 12 into the space 15 within the charge 14, 18 which comprises two spirals of nitro-cellulose strip secured to the headpiece 12. The valve 7 closes upon its release. Since the passage 4 is of substantially the same area as the head 1 the gases flowing therethrough act upon the head 1 so that the full cross-section of the valve and shank are utilized to effect the final opening of the valve; to prevent the valve spring 2 from becoming coil bound the limit of valve opening is defined when an element 5 abuts the end of the spring casing 6. The rotary valve may be replaced by a slide valve and either valve may be constructed as a normally closed valve. A relief device 19 is fitted to the base of the chamber 9.

Filed: 1966-07-15
Abstract: 1,120,912. Typewriters. BATTELLE DEVELOPMENT CORP. 15 July, 1966, No. 31972/66. Heading B6F. An attachment for a typewriter which detects the irregularities in time between depression of successive keys, comprises a line-feeding device which operates continuously during a letter-spacing movement of the typewriter platen or type-carriage. The attachment comprises two end-plates 20 spaced apart by rods 21, 22 one carrying an electric motor 25 which drives a shaft 26 having a paper feed roller 27. The rod 21 also supports a pair of upwardly and rearwardly curved arms 28 carrying a gripping roller 31 which urges the paper P into engagement with the feed roller 27. The roller 31 may be moved away from roller 27, against the bias of a spring 33 by a bail 35 operated by a hand lever 34. The attachment is held in place by clips 37. Since the paper is being fed continuously in line-spacing direction and moves in letterspacing direction according to the operations of the keys by the typist the resultant typed matter will be on an inclined line. The change in the angle of the line denotes the irregularities in typing. Fig. 6 (not shown) illustrates that the invention may be applied to typewriters having a movable type-carriage.
