Title: Improvements in and relating to automatic rivet feeding attachments for rivetting machines
IPC: B21J15/32
Filed: 1962-02-23
Abstract: 964,135. Shoots and hoppers. JUDSON L. THOMSON MANUFACTURING CO. Feb. 23, 1962 [Oct. 10, 1961], No. 7124/62. Heading B8S. Rivets fall from hopper 20, Fig. 4, into the interior of a rotating ring 28 formed with slots 60 which are cut thereinto from the interior to the exterior so that a correctly positioned rivet is entrained in a slot and carried round by the ring for discharge into shoot 84. As shown in Fig. 3 the rivet head H is withdrawn from slot 60 by a guide 70 which is positioned so that the rivet is tipped away from ring 28 to avoid the rivet being bruised. The ring is driven by a D.C. motor having a low stalling torque to prevent damage to the rivets in the event of jamming. Level device.-The height of rivets in shoot 84 is monitored by a photocell or spaced electrical contacts which control the driving motor. Normally the rivets falling intermittently past the cell or contacts do not affect the running of the motor. If however the riveting machine is not working and the rivets mount up the light beam will be permanently interrupted or the circuit closed through the column of rivets to cut out the motor. A similar level detector may be incorporated to detect a fall in the level of rivets in the shoot 84 due to the hopper 20 becoming empty. The detector may operate a warning device or stop the machine.

Title: Gathering machine
IPC: B41F13/64
Filed: 1972-02-16
Abstract: 1373036 Feeding and delivering sheets HARRIS CORP 16 Feb 1972 [5 April 1971] 7177/72 Heading B8R Collating sheets.-A plurality of V-shaped pockets 12, Figs. 1 and 2, are moved by a rotating turret 10 below a plurality of stationary feed stations 21a-21f and through a delivery station 41. In normal operation, each pocket is moved in succession past each feed station and receives thereat one sheet such as a folded newspaper section, the complete newspaper being removed from the pocket at the delivery station. At the delivery station, a cam 45, Figs. 1 and 4, acts on a cam follower 46 to move a pivoted plate 66 clockwise. The plate 66 carries a pivoted bell-crank lever 70, an arm 70a of which engages in a notch 65a of an arm 65 so as to rotate the arm 65 clockwise and thereby rotate the back wall 50 of the pocket which is at the delivery station, so as to open the bottom of the pocket and allow the assembled sheets therein to drop on to a delivery conveyer. If a sheet has not been fed into a particular pocket at a particular feed station, then, by means of an electronic control circuit including a memory, when the pocket reaches the delivery station, a solenoid 68 causes a cam 76 to be moved into an operative position in which it acts on a cam follower 74 to swing the arm 70a clear of the notch 65a, so that the faulty sheet assembly is not delivered. Also, by means of the control circuit, when the absence of a sheet being fed is detached at a feed station, all the feeding means at the remaining feed stations are rendered inoperative in turn as the particular pocket reaches the stations, until the pocket comes again to the station where the misfeed occurs, at which station the feeding is resumed, so that a correct assembly can finally be delivered.  Feeding sheets.-Each feeding station comprises a hopper 19, Fig. 2, in which a pile of sheets is supported on a ledge 28 and on a movable shoe 29. In normal cyclic operation, for the feed of each sheet, the shoe 29 is withdrawn to free the front edge of a sheet, a vacuum suction 33 pulls the sheet downwardly, and a finger 23 on a rotating drum 22 grips the leading edge of the sheet to withdraw it from the pile and carry it round the drum, the finger 23 opening to drop the sheet into a pocket 12. When the absence of a sheet is sensed by a caliper-type detector 34, suction is cut off from the suckers 33 of the remaining feed stations as the pocket reaches them, to prevent feed into a pocket containing a faulty assembly of sheets and the solenoid 88, Fig. 4, is energized to preventoperation of the delivery means when the pocket reaches the delivery station. In the event of double feed, the detector may operate a warning signal or stop the apparatus.

Title: Tuning indicator valve
IPC: H03J3/14
Filed: 1952-03-21
Abstract: 730,548. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. March 21, 1952 [June 15, 1951], No. 7382/52. Class 39 (1). In a voltage indicator having a bowl-shaped anode coated internally with fluorescent material, a rod-like cathode extending at right angles to the plane of the rim of the anode, and a deflecting electrode whose potential determines the magnitude of the shadow angle, the envelope is elongated and the longitudinal axis of the cathode makes an angle greater than 30 degrees with the longitudinal axis of the envelope. This enables the length of the anode rim to be increased, so increasing the sensitivity, the luminous pattern being viewed through the side of the envelope as compared with known devices in which it is viewed through one end. In one form, Fig. 1, the cathode 1 is at right angles to the tube axis and serves as a common source for the indicating section 2 and amplifier section 3. Amplifier anode is connected to indicator deflecting electrode 5, and the indicator section also has grid 6 and anode 7. For narrow shadow angles, the beam length is greater than the envelope diameter; the lower end of the anode may be rounded, Fig. 2 (not shown), or pointed, Fig.. 3 (not shown). In another embodiment, Fig. 4, the indicating section including grid 11 and deflecting electrode 12, and the amplifying section comprising grid 13 and anode 14, are placed on opposite sides of common cathode 10. In another form, Fig. 5 (not shown), two indicating sections are arranged on opposite sides of the cathode. When the amplifier section is spaced axially from the indicating section, as in Fig. 1, the cathode diameter may be larger in the amplifier section than in the indicator section. The part of the envelope through which the image is viewed may deviate from a cylindrical shape to assist viewing.

Title: Circuit for Correcting Distortion in Frequeny-Shift Systems.
IPC: H04L27/16
Filed: 1968-02-15
Abstract: 1,162,451. Thresholding circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 15 Feb., 1968 [17 Feb., 1967], No. 7514/68. Heading H3T. A circuit for preventing distortion in a frequency shift system due to variation in the D.C. level from the frequency discriminator, comprises a capacitor providing a correcting bias, two charging circuits connected respectively to potentials corresponding to the desired output levels and which are respectively rendered operative during the two signal conditions and comparators which clamp the output voltage when the capacitor reaches a potential producing the desired signal level. The voltages U o +U s  and U 0  - U s  representing the desired output levels of the signal are provided by potentiometers R1, R2 and R6, R7 whilst a capacitor C3 providing the correcting bias is normally biased to the mean of these levels by a circuit R3, R4, R9, R8. The output of the frequency discriminator together with the correcting bias is applied at A and the output of a Schmitt or electromagnetic threshold circuit fed from the discriminator via an inverter is applied to B. When the signal is at the lower level, T3 conducts and C3 tends to discharge through diodes G2 and T3. If drift is present, making the mean level too high the capacitor will discharge until the corrected signal at A reaches the desired level U o  - U s , whereupon T2 conducts and clamps the output voltage. If the drift had been in the opposite direction, the current through T2 would have charged the capacitor until the value U o +U s  is reached. During the upper level the inverted input at B switches T3 off so that correction is effected by charging through G2 and R12 and by the action of clamp transistor T1.

Title: Improvements in or relating to thermo-setting metal alloys and production thereof
IPC: B22F1/00
Filed: 1955-03-16
Abstract: In the production of alloys of high melting metals such as Ti or Zr or their alloys with lower melting metals, such as Al, Sn, Sb, Pb, Bi or In, the high melting metal in the form of a fine powder, is mixed with the lower melting metal and the mixture is heated to a temperature slightly above the melting point of the lower melting metal.  The pasty mixture is then shaped, e.g. in moulds or dies, and is heated to an elevated temperature until the metals have interdiffused to form a substantially homogenous alloy.  The initial mixture may be formed with the lower melting metal in the state of powder or alternatively the high melting powder may be immersed in a melt of lower melting metal any excess of molten metal being removed till a pasty mixture results. Preferably after shaping the mixture the mass is then raised to a higher temperature to cause interdiffusion, e.g. in the formation of alloys of Ti or Zr the shaped mass may be heated to a temperature in the range 1200-2000 DEG F.

Title: Improvements in or relating to marihuana-like compounds
IPC: C07D311/80
Filed: 1948-03-18
Abstract: Compounds of the formula <FORM:0651653/IV (b)/1> where R is an alkyl group of 1-5 carbon atoms, one of R1 and R2 is hydrogen and the other is an alkyl group of 1-5 carbon atoms, and R3 is an alkyl group of 1-8 carbon atoms, are obtained by the methods of the parent Specification, i.e. cleaving the ether groups of a 3 : 5-dimethoxy -1-(R3-CHR2-CRR1)-benzene and condensing the resulting substituted resorcinol (1) with pulegone, or (2) with an alkyl 5-methylcyclohexanone-2-carboxylate and treating the resulting dibenzopyrone with an alkyl magnesium halide.  The hydroxyl group in the products may be acylated or alkylated, e.g. to form the acetate or methyl ether, and the double bond in the left-hand ring may be reduced.  The substituted resorcinol dimethyl ethers may be obtained as follows: in the case where R1 is hydrogen, 3 : 5-dimethoxy-benzamide is reacted with a sec.-alkyl magnesium halide to give a sec. - alkyl - (3 : 5 - dimethoxy - phenyl) - ketone, which is then reduced to the carbinol, dehydrated with sulphuric acid and catalytically hydrogenated; thus, 2-(3 : 5-dimethoxyphenyl)-3-methyl-pentane, 2-(3 : 5-dimethoxyphenyl)-3-methyl-octane and 3-(3 : 5-dimethoxyphenyl)-2-methyl-pentane are prepared.  In the case where R1 is alkyl, the same treatment is applied to an alkyl-(3 : 5-dimethoxy-a a -dialkyl-benzyl)-ketone which can be obtained as follows: 3:5-dimethoxy-benzoic acid is converted into the acid chloride with thionyl chloride and heated with ethanol to give the ethyl ester; this is treated with hydrazine to form the acid hydrazide and acylated with p-toluene-sulphonyl chloride; the resulting sulphonyl-hydrazide is decomposed with glycerol and potassium carbonate yielding 3 : 5-dimethoxybenzaldehyde, which is then reduced to 3 : 5-dimethoxy-benzyl alcohol; this is converted into the chloride with thionyl chloride and then into the cyanide, which is alkylated to give the 3 : 5-dimethoxy-a a -dialkyl-benzyl cyanide; reaction of this with a p  Grignard reagent yields the desired ketone.  2-Methyl-2-(3 : 5-dimethoxyphenyl)-3-pentanone and 2-methyl-2-(3 : 5-dimethoxy-phenyl)-3-octanone are thus prepared, and the keto group converted into a methylene group as described above. Specifications 558,554 and 564,827 are referred to.
