Title: An improved filler for drawing pens, fountain pens and the like
IPC: B43L25/04
Filed: 1933-12-04
Abstract: 431,262. Dispensing liquids. ASKITOPOULOS, J. S., SynikiaKatacouzinou, Serres, Greece. Dec. 4, 1933, No. 34004. [Class 102 (ii)] [See also Group XV] In a filler for fountain pens &c. the delivery tube 5, Fig. 2, may be rigidly attached to the flexible member 6, which is in the form of a cup-shaped or disc-like resilient member, the edges 9 of which are gripped between the rim of the receptacle 1 and a suitably shaped lid 7 screwing or clipping on to the neck of the receptacle. Alternatively, the edges 9 may be beaded to engage over the beaded edge of a receptacle, when the lid 7 may be dispensed with. The tube 5 is provided at its upper end with a projection 3 to which pressure may be applied, the extent to which the tube and member 6 can move being determined by an adjustable nut 19 which is brought into engagement with the lid 7. The mouth 4 of the tube is formed by opening the tube at its upper end and pressing it out into a channel; the opening is normally closed by a removable pin. When pressure is applied, ink rises through the tube 5 and is delivered through the mouth 4 to the drawing pen &c. An aperture 13 may be provided for preventing ink rising in the tube due to changes in atmospheric conditions, this aperture being sealed during the beginning of the downward movement. Alternatively, the tube 5 may be made large enough to prevent ink escaping due to such changes. A cap 8 is provided. In a modification, the tube is rigidly connected either permanently or detachably to the ink receptacle 1, the base of which is closed by a flexible diaphragm, situated over a projection provided on the base of an outer container. The receptacle is normally maintained in an elevated position by springs, but when pressure is applied to the member 3, the receptacle descends and the projection on the container pushes in the diaphragm, causing ink to be ejected from the mouth 4. For filling fountain pens of the type having a spring- pressed valve 30, Fig. 8, seated in the end of the barrel 31 the outlet to the tube 5 is furnished with a rubber seating 26 upon which the end of the pen is pressed, while the end of the tube 5 engages and opens the valve 30 to permit ink to pass into the barrel.

Title: Log chipping apparatus
IPC: B27L11/00
Filed: 1969-07-08
Abstract: 1,271,026. Log chipping apparatus. MORBARK INDUSTRIES Inc. 8 July, 1969 [5 Aug., 1968], No. 34294/69. Heading B5L. Log chipping apparatus includes means for feeding a log 40 towards movable chipping means at a chipping station 1, stop means, means for moving the stop means from a first position to a second position in the path of the log for engagement with the log to interrupt its movement toward the station 1, and operating means which are responsive to changes in the rate of movement of the chipping means for moving the stop means between its two positions. The arrangement is such that the stop means interrupt feed of the log when the speed of the chipping means falls below a certain value. In the apparatus shown the log 40 is fed by a conveyer 15 to a chipping disc 5 which includes cutting blades 8 and fan blades 9. The blades 9 direct the cut chips into a shoot 50. The disc 5 is driven from the shaft 17 of an engine 16, and a tachometer monitors the speed of shaft 17. When the shaft speed falls below a predetermined value, the tachometer causes a switch to be closed which actuates a relay. The relay operates the control valves of an hydraulic cylinder 28 so that the piston-rod 31 thereof is extended and pivots an arm 22 so that a blade 26 carried by the arm engages the log 40 to hold it in position. The blade 26 constitutes the stop means. The relay also de-energizes an hydraulic motor for the conveyer 15 so that feed of the log is halted. When the shaft speed again increases the switch and relay are again operated to lift blade 26 and re-start conveyer 15.

Title: A high speed screw-cutting and profiling attachment for lathes
IPC: B23Q35/10
Filed: 1953-12-11
Abstract: 739,228. Copy-turning; lathe tool-holders. STORY, F. H. Dec. 11, 1953 [Dec. 15, 1952], No. 34528/53. Class 83 (3). A screw-cutting and profiling attachment for a lathe comprises a hollow guide 3 fixable to the lathe saddle, a fixed straight or profiled member 2 extending transversely through the guide and a tool-carrying member 4 reciprocable in the guide engaging the fixed member 2 and following its contour on traverse of the saddle to produce a corresponding screwed or profiled surface on work supported by the headstock-spindle. The guide 3 has a roller 10 to bear against one side of the member 2 while the member 4 is loaded by a spring 19 to maintain a roller 12 thereon against the opposite side of member 4. Prior to its return stroke the tool is retracted from contact with the work by a lobe 8 on member 2 and is held in retracted position by a spring- loaded pawl 15 and a ratchet 16. This pawl is pressed into engagement with the ratchet by a roller 11 acting through levers 6, 14. When the tool reaches the end of its return stroke an adjustable lobe 8a displaces member 4 further in a rearward direction and thus allows pawl 15 to move clear of ratchet 16 under the influence of a spring 27. The member 4 and the roller 12 are now free to follow the profile of the member 2 on the next cut. The member 4 has a dovetailed holder 5a to receive a carbide-tipped tool 20 adjustable by a grub screw 21 and clamped by further screws. The holder 5a may be either rigidly or pivotally connected to the member 4. The tool 20 may be withdrawn on emergency by a manually-operable lever 9.

Title: Improvements in backward wave antennas
Inventor: MOUNTFORT SIMON JOHN LOUIS
IPC: H01Q9/14
Filed: 1968-07-19
Abstract: 1,220,147. Aerials. DECCA Ltd. 9 July, 1969 [19 July, 1968], No. 34623/68. Heading H4A. A wide-band aerial array in which a plurality of elements of different lengths are coupled to a two-wire feeder along its length comprises means for switching a low impedance or a short circuit across said feeder so as to render part of said plurality of elements ineffective. As described, a log-periodic array 10, Fig. 1, comprises parallel dipole elements which are disposed on a trapezoidal dielectric plate 11. Alternate dipole halves of the array are disposed on opposite sides of the plate, the halves 12 on the front being connected to the outer conductor 13 of a coaxial feeder 14 and the halves 15 on the rear being connected to the inner conductor 16 of said cable, which is extended for the purpose. Voltage responsive networks 30, 31, 32, Fig. 4, are disposed within the thickness of the plate and at spaced intervals along the two-wire feeder constituted by the outet conductor 13 and the extension of the inner conductor 16. The networks comprise suitable active elements, such as diodes, and they may be rendered successively conductive by varying the voltage applied by a battery 22 through a variable resistor 36 and a switch 37. When the switch is closed, the part of the array to the right of a network which has been rendered conductive and of low impedance, is no longer effective, and the array bandwidth is correspondingly reduced. A high-pass filter 17 prevents the appearance of D.C. bias signal in an output channel. In another embodiment, a single diode is disposed at an intermediate point of the array, and may be rendered conductive by a biasing voltage (Fig. 2, not shown). In another embodiment, two diodes are disposed at respective intermediate points along the array, and are relatively reversed across the two-wire feeder. A reversing switch in the bias supply allows either diode to be rendered conductive (Fig. 3, not shown). Diodes used may be of the p-i-n junction type.

Abstract: 321,570. Walker, M. Nov. 26, 1928. No Patent granted (Sealing fee not paid). Presses, mechanical.-Mechanical presses are fitted with friction clutches for disengaging the driving-gear when a predetermined maximum pressure is produced; the clutches being actuated bv the axial movement of a worm under the thrust of the load. In the illustrated form the pressure head is carried on the vertical screwed shaft 8 driven by worm gearing 12, 13 through the forward and reverse clutches 14, 15. At the limiting pressure the worm swings the lever 17 against the action of the spring 16 and thus causes a member 21 to trip the lever 22 to release the spring-influenced member 24 which is linked to the clutches and is returned by the springs upon release to a neutral position in which the forward clutch 14 is disengaged. When the controlling handle 30 is operated to move the member 24 axially to the reversing position, a memher 34 on the press head engages the lever 33 and again releases the member 24 to disengage the clutch 15.

Abstract: 1354528 Separating Na salts ESSO RESEARCH & ENG CO 23 July 1971 [27 July 1970] 34763/71 Heading C1A [Also in Division C2] Sodium salts are separated from one another and from other salts or impurities including other Group Ia or IIa salts (e.g. KI) by complexation of an " inorganic " sodium salt having a maximum lattice energy of 180 kcal/mole with an aliphatic or cycloaliphatic (includes heterocyclic) chelating agent containing at least one functionality selected from secondary and tertiary amine groups and at least one other functionality selected from secondary and tertiary amine groups and an ether group, optionally in the presence of a solvent. The term " inorganic " as applied to the sodium salt, which forms the novel, thermodynamically stable chelate complex, is defined as excluding those salts wherein a hydrocarbon radical is directly bonded to the Na atom (e.g. n-butylsodium and phenylsodium). Suitable salts include NaNH 2 , NaCN, NaSCN, NaSH, Na 2 CO 3 , NaHCO 3 , NaOH, NaO-alkyl and NaBH 4 . Specific Examples 11 to 14 describe the separation of NaI/NaCl, NaI/KI, NaClO 4 /NaI and NaBH 4 /NaI solid mixtures using as chelating agent, PMDT (N,N,N<SP>1</SP>,N<SP>11</SP>,N<SP>11</SP>-pentamethyldiethylenetriamine). In the case of the solid NaI/NaCl mixture, the thermodynamically stable PMDT-NaI complex dissolves in the solvent, benzene, leaving the solid NaCl behind and pure NaI is recovered by heating the solution of the complex to 75‹ C. to precipitate the salt. Destabilization of the complex to produce the pure salt may also be effected with acids or bases.

Title: Improvements in and relating to the manufacture of chlorinated rubber products
IPC: C08C19/12
Filed: 1933-12-11
Abstract: Chlorinated rubber products of improved stability are obtained by precipitating solid chlorinated rubber from solutions thereof by addition of methyl alcohol, separating the precipitated solid and bringing it into intimate contact with a further quantity of methyl alcohol.  The precipitated solid may be redissolved and reprecipitated by methyl alcohol one or more times prior to the final washing with methyl alcohol.  In an example a solution of rubber in carbon tetrachloride is chlorinated, the resulting solution is treated with a basic substance such as soda ash and filtered to removed solid matter, solid chlorinated rubber is then separated from the solution as above.  Films of chlorinated rubber may be obtained by evaporation of solutions of the chlorinated rubber obtained as above in solvents such as benzene in which is incorporated a plasticizing agent e.g. up to 33 per cent dibutyl phthalate of the weight of chlorinated rubber.
