Title: Method and means for performing operations on strip-like material
IPC: B23D36/00
Filed: 1959-02-20
Abstract: 870,571. Shearing. WEAN ENGINEERING CO. Inc. Feb. 20, 1959 [Sept. 22, 1958], No. 5880/59. Class 83 (4). In a " flying " cutting, pressing &c. machine 3 for performing operations in cycles on moving strip material 2, a feed-stop 6 stops movement of the strip, which is again fed to a selected point in the cycle of the machine so that the first operation performed on the strip occurs at a controlled distance from its leading end. As applied to cutting the strip into lengths in a flying shear which need not cut at every cycle, waste is reduced by making the first cut close to the leading end of the strip. The strip is uncoiled by a variable-speed electric motor (not shown) and fed over a table 1. As it approaches the stop 6, which is operated by a pneumatic cylinder 8, it passes between a lamp 11 and a photo-electric cell 10 which stops the feed-motor, the strip moving on to stop 6 under its own inertia and tripping a flag-switch 9 which withdraws stop 6 and starts a variablespeed electric motor (not shown) for operating the shear 3. A flag-switch 12 operated by the shear-blades 13 as they close, energizes a relay which engages a clutch 16a, 17a between a gear-box 15, coupled with the drive for the rolls 5 of a feeding-and-straightening device 4 which is driven synchronously with shear 3, and a signal generator 18. Pulses from a cam-operated switch in generator 18 register further movement of the shear and are fed to a counter 20 which at a pre-set count re-starts the feed-motor and when the rolls 5 engage the strip, energizes a timer. This switches the feed and shear motors to a faster speed and disengages the clutch 16a, 17a, the timer being set to return the apparatus to the condition for receiving another strip when the preceding strip has been used up. The counter may be calibrated in sheet lengths and set manually or by remote control. Switches may be operated manually to stop the feed and move stop 6 during setting-up. The voltage on the motors may be, regulated by a Ward Leonard control system. An electric control system is described. Specification 857,861 is referred to.

Title: Magazine pencil
IPC: B43K24/10
Filed: 1926-03-03
Abstract: 268,936. Nardi, R. March 3, 1926. Pencil holders.-A magazine pencil holder comprises telescoping casing-members one of which carries a frame to which a locking-member is secured, the locking-member being engageable by a clutch in the other casing-member to hold the parts in telescoped condition, and an ejector cooperating with lead-carriers in one of the casing- members is provided for effecting the projection of the leads. The casing-members 25, 31, Fig. 2, the former of which carries a tip 27, are provided with shoulders to limit their relative outward movement. A frame 33 is fixed in the member 25 and is formed with a number of longitudinal grooves which converge towards the lower end. In the grooves are mounted tubes 58 each having a polygonal rear end 59, Fig. 10, a screwthreaded portion 72, and a flanged forward end 60 provided with a side opening. The leadcarriers 63, Fig 2, are formed with a flange at the rear end adapted to be mounted in the opening in the flange 60, and with a slot 64 extended nearly the whole length of the carrier. The carriers pass through openings 65, Fig. 7, in a ring 66 mounted for slight play in the casing-member 25, the openings being provided with tongues 67 projecting into the slots 64 to prevent rotation of the carriers. The lead-propellers 69 are mounted in the carriers 63 and are formed with a screwthreaded part engaging the part 72 in the corresponding tube 58, and with a fin 70 projecting through the slot 64. Each lead carrier is surrounded by a spring 74 tending to hold the casing- members apart. A headed plug 36, Figs. 2 and 3, is fixed in the rear end of the frame 33, and is adapted to be engaged, when the casing-members are telescoped, by a spring-pressed clutchmember 42 mounted in a slot 41 in a member 40 secured to the casing-member 31. The clutch is adapted to be released by pressure on a pin 49 passing into the slot 41 through openings in the casing member and a pocket-clip 51, a shoulder on the pin preventing its removal. The clutchmember 42 is pivoted on a pin 43 to the upper end of which a gear-wheel 44 is attached. The gear-wheel is engaged by an internal gear on a rotatable cap 54 and is held in a recess in the member 40 by a washer 57 secured by a shouldered pin 56 which also serves to retain the cap in position. The two parts of the casing are relatively rotatable, and are provided with indicating,marks to show which tube 58 is opposite the pin 43. When the desired adjustment has been made, the casing-members are telescoped, the tube 58 opposite the pin 43 being prevented from movement and thus being projected, against the action of its spring 74, beyond the end of the tip 27. To effect a feeding forward of the lead relatively to its carrier, the cap 54 is rotated to cause rotation of the wheel 44 and pin 43, which is provided with a polygonal end engageable with the similarly-shaped ends 59 of the tubes 58.

Title: Improvements in projectiles fitted with an electric generator of the inertia type
IPC: F42C11/04
Filed: 1961-02-21
Abstract: 927,055. Projectile fuzes. BREVETS AERO-MECANIQUES S.A. Feb. 21, 1961 [March 1, 1960], No. 6280/61. Class 9 (1). An electric generator, for projectiles with relatively low acceleration on launching, such as rockets or rifle grenades, comprises a casing 3, coil 4, bar magnet 5 and a casing 12 which houses a capacitor connected to the firing circuit by means of a flexible wire 13. The casing 3 is slidably mounted in a cylindrical housing 8 of the projectile and is normally prevented from moving rearwardly by a screw 9 which bears on a disc 10. The bar magnet 5 is slidably mounted within the coil 4 and this in turn is normally prevented from moving rearwardly relative to the coil by a wire 6. The disc 10 and wire 6 are both frangible and their relative strengths are such that disc 10 ruptures immediately on launching so that the generator sets-back due to inertia and wire 6 breaks with consequent set-back of the bar magnet when rear abutment 7 strikes the generator giving it a forward acceleration greater than the initial launching acceleration.

Title: Improvements in or relating to electric circuit arrangements such as are employed asswitching devices, for the generation of electrical waveforms and for other purposes
IPC: H03K3/06
Filed: 1944-04-06
Abstract: 584,740. Multivibrator circuits. CUTTS, F. W. April 6, 1944, No. 6421. [Class 40 (v)] In a cross-connected pair of valves employing capacity coupling, means are provided for rendering both of the valves non-conducting by a controlling pulse whereby after the termination of the pulse the previously conducting valve becomes non-conducting and vice versa. The circuit may be employed as a frequency divider of pulses or for switching signal into different channels. Valves 1, 2 cross-connected over condensers 4, 6 operate with one valve conducting the resulting drop in screen grid potential due to the current flow lowering the potential of the control grid of the other valve sufficiently to maintain it in the cut-off condition. A negative pulse applied to the grid of valve 13 cut off the anode current, the potential of the cathodes of valves 1, 2 rising to render both non-conducting. After the termination of the pulse, valve 13 conducts again and as the cathode potential of valves 1, 2 falls the previously non-conducting valve conducts since the potential drop across the corresponding condenser 4, 6 is less than for the previously conducting valve. Alternatively a positive pulse may be applied to the grid of valve 14 coupled to valve 13 over cathode resistance 15. Where the pulses are regularly recurring, the resistances 3, 5 may be omitted. Reference has been directed by the Comptrotler to Specification 572,884.

Filed: 1975-02-17
Abstract: 1487663 Hydrotreating catalysts LABOFINA SA 17 Feb 1975 [18 Feb 1974] 6641/75 Heading BIE  A catalyst for hydrogenating petroleum hydrocarbon fractions is produced by forming an aqueous mixture comprising alumina hydrogel and at least one water-soluble ethylenic monomer whose uncross-linked polymer is water-soluble or forms a gel, and introducing this mixture in the form of droplets into a hot substantially water immiscible fluid whereupon the monomer polymerises and the polymer formed agglomerates the alumina hydrogel to form beads which are recovered and subjected to thermal treatment, at least one oxide or sulphide of a Group VIII metal and at least one oxide or sulphide of a Group VIB metal being included in the beads by the addition of compounds which are, or are capable of generating said oxides or sulphides, to said aqueous mixture and/or to the recovered beads before the thermal treatment. In preferred embodiments, the aqueous mixture is passed as droplets in counter-current to a hot dry gas. Alternatively the aqueous droplets are dispersed at the bottom of a column containing a hot liquid such as chlorinated biphenyl having a density greater than that of the formed beads, which are recovered at the top of the column on the liquid surface, or the droplets are dispersed at the top of a column of hot liquid such as paraffin oil which has a density lower than that of the formed beads, which are recovered at the bottom of the column. In the examples catalysts consisting of molybdenum oxide and cobalt oxide supported on alumina beads, and nickel oxide, cobalt oxide and tungsten oxide supported on alumina beads, are produced. The thermal treatment normally involves drying and calcination. The Groups referred to belong to the Periodic Table in the Handbook of Chemistry and Physics (Chemical Rubber Co), 49th Edn.

Patent GB-699075-A (GB)
Title: Ethers of hydroxy aldehydes
IPC: C07C45/62
Filed: 1950-03-17
Abstract: The invention comprises olefinic-unsaturated ethers of hydroxy aldehydes which may be prepared by reacting a primary olefinic p alcohol containing one or more double bonds with an a  : b  - olefinic unsaturated aldehyde in the presence of an alkaline condensation catalyst at a temperature below +10 DEG  C.  The unsaturated ethers include those having the formula <FORM:0699075/IV (b)/1> wherein R1 is hydrogen, an alkyl or a phenyl group, R2 is hydrogen or an alkyl group and -OR3 represents the residue of allyl alcohol, methyl-, ethyl-, propyl- or other 2-alkyl substituted allyl alcohol, cyclohexyl allyl alcohol or cinnamyl alcohol.  As alkaline condensation catalysts there may be used sodium or potassium hydroxide, alkali metal alkoxides, e.g. those of the primary olefinic alcohol reactant, organic bases such as triethylamine and quaternary ammonium bases, e.g. trimethyl benzyl ammonium hydroxide; they may be used in aqueous or alcoholic solution.  The alcohol is preferably used in large excess over the unsaturated aldehyde.  The ethers formed may be recovered by acidifying the mixture, e.g. with phosphoric acid, if desired after neutralization with an acid, preferably an organic acid, e.g. acetic acid, and then distilling. The unsaturated ethers of the aldehydes may be converted into acetals by reaction with alcohol in the presence of an acidic condensation catalyst. The ethers may also be saturated in the olefinic double bond by selective hydrogenation generally at between 15 DEG  and 50 DEG  C. under pressures of up to 3 to 5 atmospheres and using not more than one mole. of hydrogen per mole. of ether-aldehyde, a suitable catalyst being palladium or charcoal.  The unsaturated ethers may also be used as intermediates for the manufacture of polymers and oxidation products.  The saturated ethers containing propoxy and butoxy groups may be converted into corresponding acids and alcohols which may be used to produce esters forming high-boiling solvents or plasticizers.  In examples: (1) acrolein is reacted with allyl alcohol in aqueous sodium hydroxide at -10 DEG  C., yielding 4-oxahept-6-enal; the unsaturated ether-aldehyde is reacted with ethanol using H2SO4 as catalyst to form its acetal; the ether is also hydrogenated in ethanol solution using Adam's catalyst to form 4-oxaheptanal; (2) methacrolein is similarly reacted with allyl alcohol to form 2-methyl-4-oxahept-6-enal which on hydrogenation yields 2 - methyl - 4 - oxaheptanal; (3) acrolein and methyl allyl alcohol are likewise reacted to form 6 - methyl - 4 - oxahept - 6 - enal which is then hydrogenated to 6-methyl-4-oxaheptanal; (4) crotonaldehyde and allyl alcohol similarly yield 3 - methyl - 4 - oxahept - 6 - enal which is hydrogenated to 3-methyl-4-oxaheptanal. The semi-carbazones and 2 : 4-dinitrophenyl hydrazones of the unsaturated and saturated ether-aldehydes are described.  Cinnamyl aldehyde is also mentioned as an aldehydic reactant.
