Title: Improvements in or relating to driver's brake valves
IPC: B60T15/04
Filed: 1967-03-30
Abstract: 1,142,386. Driver's brake valves. KNORRBREMSE G.m.b.H. 30 March, 1967 [30 March, 1966], No. 14675/67. Heading F2F. In a driver's brake valve, having a plate 3, Fig. 1, arranged at the outer end of the valve spindle and provided with a handle 4, an eccentric spring-loaded knob 6 has an abutment 7 which in its normal position engages a bellcrank lever 9 one arm of which serves as a control lever for a filling stroke valve 11. The spindle 1 is rotatable by handle 4 so that in the running position (F), Fig. 2 (not shown) the abutment 7 bears against bell-crank lever 9. When the driver's brake valve is moved into the filling position (F ST ) the bell-crank lever presses valve member 11 into the housing to open valve 12 to initiate filling. The abutment of the lever arm against housing surface 10 prevents further rotation of the spindle beyond the filling position (F sr ). If the system tightness testing position (D) is to be selected knob 6 is pulled upwardly against spring 5 so that the spindle can be rotated without actuation of valve 11. If the spindle is then moved in the opposite direction through the filling position (F ST ) the abutment 7 rides up along surface 13 without initiating filling.

Patent GB-361361-A (GB)
IPC: C09B1/28
Filed: 1930-05-15
Abstract: <PICT:0361361/IV/1> <PICT:0361361/IV/2> The method of treating regenerated cellulose threads in package form in which liquid is forced transversely through the package and in which the package is permitted to expand longitudinally is carried out in such manner that the predetermined limited expansion of the package is made proportional to the number of filaments which make up the thread of the package and, for a package of 3\ba1/2\be in. depth and comprising 44 filament 300 denier thread, is equal to one-eighth of an inch.  As shown in the drawings, apparatus for carrying out the process comprises a number of bases 3 disposed on the horizontal platform 2 of a wash rack, above which bases are placed in spaced relation through the medium of inclined cores 6, a plurality of spacers or abutments 4. A cap member 12 is placed on top of the topmost core. The cores p  are longitudinally split as shown in Fig. 8 and are collapsable or expansible.  A thread cake is placed on each core and is disposed between the flanges of adjacent spacer members 4.  The spacing of the members 4 is such that adjacent flanges are disposed farther apart than the depth of the thread cakes so as to provide spaces 8 between the tops of the cakes and the lower flanges of the spacing members.  The spaces 8 are selected so as to permit longitudinal expansion of the cakes by the amount defined.  In assembling a cake 5 on a core 6, a cloth such as a knitted fabric may first be drawn through the cake and the compressed metal core then inserted through the cloth.  Treating liquid is fed under pressure through the pipe 17 into the interior of the cores 6, through the perforations 7 therein, and transversely through the cakes.  During the initial stages of the treatment, the cakes expand longitudinally into the spaces 8, until they abut against the superposed spacing members 4, when further elongation is prevented.  In the initial stages, if the resistance of the cakes to the transverse passage of liquid is great, the spaces 8 provide relief for the passage of liquid. When treating the cakes with water, the treatment is complete in from 15 to 90 minutes according to the temperature of the water. Hot water is stated to effect simultaneous washing and desulphurizing.  Clamping mechanism is provided for preventing the pressure of the treating liquid from lifting the spacer members 4. The clamping device is of the form described in Specification 356,737.

Title: Method for preparing monoacyl derivatives of antibiotic t-2636c
Filed: 1970-03-31
Abstract: 1310712 14-Monoacylates of antibiotic T-2636C TAKEDA YAKUHIN KOGYO KK 31 March 1970 [31 March 1969] 15031/70 Heading C2A Novel 14-monoacylates of antibiotic T-2636C, wherein the acyl group has the formula R.CO- in which R is hydrogen or C 1  to C 3  alkyl, are prepared by reacting T-2636C with an organic acid ester in which the acyl group is R.CO- in the presence of a culture of a micro-organism of the genus Streptomyces, Aspergillus or Trametes or an esterase preparation derived from such a culture, and recovering the resulting T-2636C- 14-monoacyl derivative. Suitable esters are those of formic, acetic or propionic acid with methanol, ethanol, propanol, ethylene glycol or glycerine, e.g. methyl formate, ethyl acetate, ethyl propionate, monoacetin or triacetin. Preferred micro-organisms are Aspergillus sojae, Trametes sanguinea, Streptomyces hygroscopicus, Streptomyces tolypophorus or Streptomyces rochei var. volubilis. The latter is the micro-organism which produces the starting antibiotic T-2636C (Specification 1,226,665), and accordingly the present 14-monoacylate may be produced by cultivating Streptomyces rochei var. volubilis in the presence of an appropriate ester. The esterase preparation is defined as any material derived from the culture, which has the capacity to acylate the carbon atom of T-2636 at the 14- position, and which can be obtained by purifying the culture with solvent extraction or with the aid of an adsorbent material or an ionexchange resin. The reaction is effected at 20-40‹ C. and pH 4-9. The product is isolated by extraction with a water-immiscible solvent, which may be an excess of the reacting ester, followed by concentration and chromatography on silica gel to remove unreacted T-2636C, and crystallization of the required 14- monoacylate. Pharmaceutical compositions having antibiotic activity comprise a 14-monoacylate of antibiotic T-2636C as defined above together with a pharmaceutically acceptable diluent or carrier. Reference has been directed by the Comptroller to Specification 1,283,085.

Title: Conditioning molten glass
IPC: C03B7/06
Filed: 1959-05-04
Abstract: 864,969. Drawing sheet glass. LIBBEYOWENS-FORD GLASS CO. May 4, 1959 [May 12, 1958], No. 15106/59. Class 56. To control the edge to edge cooling pattern of a stream of molten glass moving along a predetermined path through a cooling area, the formation of turbulent air currents in the cooling area is avoided and the loss of heat from the glass stream is effected substantially wholly by radiation from the glass surface through an air space and through a cover, defining a part of the cooling area, having low heat reflectance and high heat conductivity properties. Silicon carbide is suggested for the cover. As shown in Fig. 1, molten glass 7 flows from a refining chamber 8 under an end wall 10 through a cooling chamber 11 to the draw pot 12 from which a sheet of glass 16 is continuously drawn upwards and deflected over a roll 17 on to idler rolls 18 into an annealing lehr. The conventional cap cover 19 of the cooling chamber 11 is made of silicon carbide and the chamber contains no water coolers. In a modification, the arched cap cover is lowered to about a foot above the glass stream at its centre point. Insulating blocks may be placed on the outside of the cover over the edges of the stream to give more uniform heat losses. External cooling pipes or heat reflectors may also be used. As shown in Fig. 3, a flat relatively thin cap cover 30 is positioned close to the surface of the molten stream 31 to give a restricted air space 32. The cap is again of silicon carbide. Heat reflectors 37 are positioned over the edges of the stream and are adjustable to control the loss of heat across the stream. Thermo-couples may be installed across the width of the stream, extending to just below and just above the surface from outside the chamber, to give the necessary data for positioning of the insulating blocks and/or reflectors.

Filed: 1947-06-20
Abstract: 616,364. Directive radio systems. BROWN, R. H. June 20, 1947, No. 15216/46. [Class 40 (vii)] In order to prevent a responder beacon from being triggered by the side lobes radiated by the directional aerial of an interrogating transmitter, an additional omnidirectional transmission is radiated by the interrogator such that the omnidirectional transmission produces a signal of greater amplitude than the directional transmission at the responder except when the main lobe of the directional aerial is pointed at the responder. The directional aerial periodically transmits a pair A, B of pulses having a predetermined time spacing suitable to trigger the responder and the omnidirectional aerial periodically transmits a single pulse C timed to occur midway between the pulses A. and B. Automatic gain control means is provided at the responder to fix a threshold level at the level of each received pulse, which level decays slowly with time. Thus, when pulses A and B are of greater amplitude than pulse C, A and B only are passed and the responder is operated. However, when pulse C has the greater amplitude only pulses A and C are passed, the time spacing of which differs from the predetermined value, and the responder is not operated.
