Title: Improvements in the process of, and apparatus for, extracting glue from glue-yielding raw materials by means of water
IPC: C09H3/00
Filed: 1921-01-06
Abstract: 156,645. Niessen, K. Dec. 8, 1919, [Convention date]. Fats, extracting.-The Specification as open to inspection under Sect. 91 (3) (a) describes the extraction of fat from bones, gristle, leather waste, animal skins, fish waste, &c., in an apparatus comprising a battery of extractors so arranged that the strongest liquor comes into contact with fresh raw material and fresh water comes into contact with material which has been steeped the greatest number of times. Each extractor A1 is provided with heating coils c into which lowpressure steam can be admitted from the pipe q, a perforated bottom b for supporting the material, and vanes d operated by gearing for circulating the steeping water round the extractor by the channel l. In addition, each extractor is connected to the next but one by a pipe r to permit of liquid being forced from one extractor to the other; and a vacuum steam pipe m, which connects all the extractors, is in communication with a condenser B and a tank C, containing a heating coil y. Each extractor is supplied when required with fresh water from the tank C by means of a pipe n, and a regulator f is provided for maintaining the desired water-level in the extractor. The liquor is withdrawn into settling tanks through the valved pipe v. During each steeping process, the extractor containing the material which has been steeped the greatest number of times is cut out for recharging with fresh material; after which it is again connected up and supplied with steeping water which has been employed the greatest number of times. In each extractor the material is treated with circulating water into which low-pressure steam is admitted. The escaping steam passes through the pipe z in the tank C, heating the water therein, and then passes to the condenser B. The condensate and heated cooling water are conducted to the tank C, a valve x1 in which actuates a bell when the tank is full. When the signal is given, the most concentrated liquor is withdrawn from the extractor containing it, another extractor is emptied for recharging with the contents of the tank C, and the steeping water of the intermediate extractors is transferred from one to another. This transfer is made automatically, for when the valve v is opened for withdrawing the liquid in extractor A1, the fall of the waterlevel therein operates the regulator f, which by mechanical means closes the valve k1 of the next extractor A2, thereby permitting the pressure to increase in extractor A2 and so drive out the contents into the next extractor. This subjectmatter does not appear in the Specification as accepted.

Title: A method of subjecting badly swelling and/or caking coal to an oxidizing pretreatment prior to coking to improve the coking properties thereof
IPC: C10L9/06
Filed: 1947-01-08
Abstract: 641,422. Oxidizing fuel. AMERICAN CYANAMID CO. Jan. 8, 1947, No. 643. Convention date, Jan. 16, 1946. [Classes 50 and 55(i)] I , To enable briquetted swelling coals to be coked under a temperature rise of at least 2‹C per minute through the plastic range, the coal pulverized so that at least 95 per cent of the particles pass through an 8- mesh screen and dried, is subjected at about 150‹-275‹C and 2-20 lbs. per sq. in. pressure to oxidation by a gas containing less oxygen than air and preferably about 5-15 per cent for a period of a few seconds to a few minutes to destroy a part only of the coking quality of the coal. A strongly coking coal is passed through a drying pulverizer 2 and hopper 3 into a fluidizing pump 4 and thence through a retort 6 in an oxidizing atmosphere, a cooling coil 8 into a hopper 11 for feeding a briquetting unit 19. The retort is heated-by. circulating highboiling fluid through a jacket or e.g., electrically.. The fluidizing air which supplies the oxygen enters the system through a valve 28, the oxygen content being controlled by admission n-of flue gases from the heater 20 for the high-boiling fluid The mixture flows through a filter 31, a moisture absorber 32, a com pressor 34 and valve 36 to the pump 4. In an example a very strongly coking coal known as Thrislington washed nuts is pulver ized to 88 per cent minus 28 mesh and passed through the oxidizing zone comprising 5 per cent oxyger at 180‹C under 10-15 lb pressure per sq. in. in 2-3 minutes. Sulphite liquor and tar-acid binders are referred to. Specification 547376 is referred to.

Title: Subsurface well apparatus
IPC: E21B34/10
Filed: 1973-01-04
Abstract: 1422393 Wells &c HYDRIL CO 4 Jan 1973 656/73 Heading E1F A subsurface well apparatus for connection in a production tubing to control flow of fluid through the tubing bore has a housing 130, Fig. 1c, having a bore 140 therethrough communicating with the tubing bore, and a movable control member 163, Fig. 1B, 164 disposed in the housing bore for cooperating with a flow control device 185, Fig. 4B, introduced into the housing bore through the production tubing bore, to move the device between an open condition and a closed flowblocking condition. Flow of liquid is normally controlled by means of a ball valve 150, Fig. 1C, rotatable about pins 167f fixed to -the housing, the valve having a slotted connection with the pins such that axial movement causes rotation. The ball valve is biassed into the closed condition by means of a spring-biased sleeve 166 and is rotated into the open condition by the application of pressurised control fluid via line 122, Fig. 1B, on a piston 163 which in turn acts via a sleeve 164 on the valve seat ring 155, a line 123 being vented. In the event of a malfunction of this ball valve 150 the ball valve is locked open by venting of the line 122 and pressurisation of the line 123 to operate a mechanism 170, 171, Fig. 1B, latching the sleeve 164, and the flow control device is run into the bore 140 by means of a tool (195), Fig. 4A (not shown), which is pumped down the bore, the ball valve 187 of the device being temporarily held closed by a shear pin (295c). When the device engages a ring 175 fluid pressure forces its frame 286a and mover sleeve 288 downwardly relative to a sleeve 290, so that dogs 293 on the device engage a recess 263 in the piston 163. A pin (295) between the tool (195) and the device 185 is sheared, and venting of line 123 causes spring 163a to urge the piston 163 upwardly to move the device so that dogs (294) thereon engage a recess (140c). In operation, the device 185 is controlled by piston 163 through a pin-and-slot connection, pressurised fluid in line 123 moving the piston downwardly to open the valve 187. Reduction of pressure in the line 123 allows spring 163a to close the valve 187. If the device 185 does not function the valve 187 is rotated to the open position and the device is withdrawn by a tool (196), Fig. 7A (not shown).

IPC: B64C23/00
Filed: 1934-01-08
Abstract: 431,646. Reaction propulsion. COANDA, H., 10, Rue Bardin, Clichy, Seine, France. Jan. 8, 1934, No. 682. [Classes 4 and 114] A method of producing thrust forces within a fluid medium for the purpose of propulsion or transmission of power consists in projecting a fluid layer at high velocty over the leading face of an inclined aerofoil to produce a depression against this face while maintaining the surrounding pressure on the reverse face of the aerofoil by replacement fluid streams. Jets or burner nozzles c project a stream of gas at high pressure into a chamber d, entraining the surrounding fluid through apertures e. The expanded gases sweep over the leading faces h of aerofoils g arranged symmetrically around an axis 0-0, producing on the leading face thereof a reduction in pressure. The pressure on the reverse face i of the aerofoil is maintained by induced streams of surrounding fluid passing through passages s.

Title: Improvements in breech-block locking mechanism for guns
IPC: F41F1/08
Filed: 1917-01-02
Abstract: 156,782. Solms, W. I., (Assignee of Luciani, J.). Dec. 30, 1915, [Convention date]. Machine guns.-Relates to hand-operated multibarrel guns of the kind described in Specifications 13404/15 and 103,125, and consists in providing locking-bolts for the breech-block which are moved by actuating members operated by arms mounted on the spindle of the breech-actuating lever, the said arms acting independently to move the breech-block. In the form shown in Fig. 1, the breech-block 3 is moved rearwardly by operating a lever 23 to allow a cartridge loading plate to fall by gravity into loading position and to cause rods 2 connected to firing pins 1 to pass between jaws 5. When the lever 23 is returned, the firing pins are held by the jaws and thereby cocked. The jaws are subsequently opened to fire the gun by operating a lever 12. The breech-block is locked in firing position by sliding blocks 26 having inclined interrupted locking projections engaging corresponding recesses in the cradle 29. The rearward movement of the lever 23 first lowers the locking-blocks through levers 21, 16, and afterwards, by the engagement of a roller 20 with a hook 25, moves the breech-block rearwards. The locking-blocks are again raised to locking position at the end of the forward movement of the breechblock. Fig. 5 shows a modified form of locking- block 32 for use when the breech-block is operated by links 39, 36. The locking-block is moved into locking position by a projection 41 on the lever 39, and is moved out of locking-position by springs 35.

Filed: 1936-01-10
Abstract: 468,761. Coin - freed apparatus. MEASUREMENT, Ltd., COWAN, E. L., and CLIFFORD, C. F. Jan. 10, 1936, No. 867. [Class 27] Returning coin.-In prepayment mechanism for meters and other commodity delivery apparatus, a coin, in passing through an insertion shoot, opens a connection to a coin return slot, which connection is closed again upon rotation of a handle operating the coin pocket, so that a second coin inserted before operation of the handle is delivered to the return slot. In Fig. 1, a coin inserted through a slot n covered by a flap o passes down a shoot a into the coin pocket b, and in passing, depresses a spring-actuated lever c forming the base of the shoot. This releases a catch f at the rear of the lever c from a plate g pivoted about a vertical axis, and forming the base of the front part of the shoot, the plate g moving clear of the shoot so that coins subsequently inserted fall to a return shoot p. The plate g is restored into its closing position by engagement of a flexible abutment on the operating shaft of the mechanism. A pin on the plate g enters the shoot a to prevent coins from passing straight down the shoot when the plate is displaced. In Fig. 4, the bottom of the shoot a comprises a lever t pivoted at u and weighted at the rear : it is held in the position shown to pass an inserted coin to the pocket by a swinging gate s. An inserted coin thrusts back the gate s to release the lever t which rises so that any further coins inserted before actuation of the mechanism are returned by way of a shoot p. The lever t is returned into its initial position by a spring v on the actuating shaft k<1>.

Title: Electronic timepiece
IPC: G04C3/00
Filed: 1976-09-30
Abstract: 1401776 Electronic timepieces SUWA SEIKOSHA K K 7 Sept 1972 [8 Sept 1971 9 Sept 1971 10 Sept 1971] 41582/72 Heading G3T A wholly electronic timepiece (e.g. a watch) having liquid crystal or light-emitting diode digital display, is provided with not more than two manually operable members (coupled to mechanical switches) for selecting part of the time indication to be corrected and resetting to zero or correcting the selected parts of the time indication individually. The switches may additionally be arranged for simultaneously resetting all of the parts of the time indication to zero. In an embodiment Fig. 9, a frequency divider DIV feeds signals at 1Hz to divider counters 1' to 5' for operating the hours, tens of minutes, minutes, tens of seconds and seconds respectively of the time display 7' in known manner. When setting, a signal applied at terminal S-R is passed by a switch Ss to a rotary selector switch So' detailed in Figs. 10 to 14 (not shown) and comprising an axially movable rotatable stem. With the selector wiper engaging a contact Sr the signal will reset all of the counters 1' to 5' and all of the parts of the time display to zero. With the wiper at a contact Sa, the hours and tens of minutes will be zeroed. Similarly the minutes will be zeroed with the wiper at contact S13 and so on. If the switch Ss is now opened and closed periodically, the appropriate part or parts of the time display can be advanced to the correct time. Fast correction of the time can be achieved by applying the output of the divider DIV selectively to the minutes and second counters Fig. 18 (not shown). In an arrangement to prevent overshoot when correcting the displayed time, Fig. 19 (not shown) a desired time indication is read into the timepiece and is continuously compared with the actual indication being corrected. Thus as shown in Fig. 20, each counter of Fig. 19 comprises two sets of binary flip-flops A, B, C, D and a, b, c, d, each set constituting a <SP>1</SP>/ 10  sub-dividing circuit X, Y respectively. For example if the desired 1-seconds indication is "5" then a setting signal is applied to terminal Sb" which sets the subcircuit flip-flops a, b, c, d for 0, 1, 0, 1. A correcting signal is then applied at Sc" and is fed to flipflops ABCD via a gate GY. When the outputs of ABCD coincide with the outputs of a, b, c, d respectively, the outputs of gates Ga to Gd and hence of gate Gw, go to "high". The output of Gw together with a control singal at Sa" make gate Gx output go high. Thus a gate Gz is caused to block correcting signals to ABCD sub-circuit and overshoot is prevented. The divider counter circuits 2', 3', 4', 5' are constructed in like manner to that of 1', in Fig. 20.

Filed: 1995-01-05
Abstract: PURPOSE: To surely engage a mounting bracket while improving efficiency of assembly work by constituting an engaging part of a pawl part provided with a bending part in the point end and of a protrusion part, also to arrange the bending part facing upward further to arrange the protrusion part in a lower side of the pawl part. CONSTITUTION: In the case of mounting a license plate lamp 5, first after a rear bumper 1 is molded, a mounting bracket 6 is bent from a thin thickness part 7, to fix the lamp 5 to an arm 13 by a screw 14. Next, the rear bumper 1 is press opened upward, to engage a bending part 10 with an engaging hole 8. Successively by restoring force of the rear bumper 1, the mounting bracket 6 is positioned, to press in the engaging hole 8 to a protrusion part 12. Thereafter, force in a direction of opening the mounting bracket 6 is impeded by the bending part 10, further to impede force downward by a pawl part 11, also to impede force upward by the protrusion part 12. In this way, efficiency of assembly work is improved also to surely engage the mounting bracket 6.

Title: Electron gun frame body for cathode-ray tube
Inventor: KAMOZAWA HIROFUMI
IPC: H01J29/04
Filed: 1984-01-04
Abstract: PURPOSE:To obtain a high reliability cathode-ray tube that can stably radiate emission for a long period of time by comprising the material of an eyelet that supports a cathode with metal material provided with a small thermal expansion coefficient. CONSTITUTION:The thermal expansion coefficient of the eyelet assembly 2 of a cathode support frame body is smaller than the thermal expansion coefficient of the material assembly 1 of a cathode. For example, both cathode 1 and eyelet 2 are welded mutually by electric welding and such. The material composition of the cathode 1 is made of Nichrome wires and the thermal expansion coefficient is 10.0X10<-6>. The material composition of the eyelet 2 is made of Cobal and the thermal expansion coefficient is 4.8X10<-6>. As a result, since the eyelet 2 has a smaller thermal expansion coefficient than the cathode 1, a change in the gap between a first grid electrode and the cathode is small and emission can be radiated stable even when the cathode material is evaporated under vacuum by long- term heating and the temperature of the cathode rises gradually.
