Title: Improvements relating to apparatus for raising and transporting loads
IPC: C10B31/00
Filed: 1929-04-23
Abstract: 331,955. Humphreys & Glasgow, Ltd., and Fryer, J. E. G. April 23, 1929. Winch - actuated hoists with guided skips.-A guided-skip hoist having a vertical or inclined track continued as a horizontal track is provided with means such as a twodiameter or two-speed winch and a balance weight to provide a slow speed on the horizontal part of the track. The load - carrying truck d runs on a vertical or as shown an inclined track b having a horizontal track a at its upper end. The hoisting rope e passes from the truck to a winch l having a larger barrel for quick hoisting and a smaller barrel for slower travel on the horizontal track. A trolly f normally rests against a stop g on the track and carries a pulley h over which passes a rope i connected at one end to the truck and at the other end to a balance weight j having rollers running on guides k. In operation, when the truck reaches the top of the inclined track it engages and carries with it the trolly and raises the balance weight, this arrangement preventing any slack in the hoisting rope as it is wound in more slowly.
Patent GB-599670-A (GB)
Title: Improvements in or relating to the production of artificial filaments, films and like materials
IPC: D01F6/60
Filed: 1940-08-05
Abstract: Artificial filaments, films and like materials are obtained by shaping a fused composition comprising a synthetic thermoplastic fibre- or film-forming polymer and a solvent medium therefor in such proportions that the composition is fusible at a temperature which does not substantially exceed 100 DEG  C., but which is solid at temperatures up to about 35 DEG  C., and setting the shaped materials by cooling.  The polymer may be a linear condensation polymer such as a polyamide.  The fused composition may be shaped by extrusion. The solvent may be phenol, a cresol, a xylenol, a naphthol, resorcinol, catechol, quinol, orcinol, formic acid, acetic acid, or a halogenated fatty acid.  Mixtures of solvents with non-solvents such as toluene, xylene, or ethyl benzene may be employed.  The proportion of solvent may be high or low provided a composition of the specified properties is attained.  Dilute solutions, which are subsequently concentrated, may be obtained directly from the process of preparation of the polymer.  The polymer in flake form may be treated with a solution or dispersion in water or other known solvent from which the polymer takes up the desired amount of solvent.  For making filaments or films the composition may be fused during passage through a narrow tube and it may be extruded under pressure applied by a gas or liquid, or by a pump.  The composition may be extruded at a temperature slightly above the fusion point.  The shaped materials may be passed through a heated inert gaseous atmosphere heated in the region of the shaping device to a temperature of the order of that of the shaped composition.  After a short travel in the hot gas, the materials may be passed through inert gas at a much lower temperature sufficient to permit completion of the setting of the materials.  If desired, a cool liquid may be used for completing the setting of the materials.  Such liquid may be sprayed on to the materials or on to a forwarding roller.  Alcohols, ethers, esters, hydrocarbons, chlorinated hydrocarbons or aqueous salt solutions may be used. Solvent may be removed from the set materials by washing with water, benzene, toluene, xylene, petroleum ether, or aqueous caustic soda solution.  The set materials may be subjected to stretching.  The compositions may contain additions of softening agents, pigments, dyes or cellulose derivatives.  Such additions may be made in the reaction mixture before polymerization.  In an example, hexamethylene diammonium adipate and phenol are heated for several hours in an inert atmosphere.  Adipic acid is added and the mixture is heated for a further period.  The composition is led through a heated narrow tube and a gear pump to a conical jet.  The extruded filaments pass through hot air and are then sprayed with a cold solution of sodium chloride.  Specifications 540,967, 541,238 and 599,668 are referred to.

Title: Electronic equipment for multistage operations in paper or like high-speed guillotines
IPC: G05B19/16
Filed: 1957-04-24
Abstract: 850,530. Guillotine cutting - machines. MOHR, R. April 24, 1957 [May 5, 1956], No. 13024/57. Class 31(1). In a guillotine of the kind having an electronic equipment comprising a record carrier and a transmission head scanning such carrier, two transmission heads are arranged one behind the other so that, in one operation, they simultaneously impart information impulses to the carrier and pick them up from it to control the machine. As shown, a back gauge 10 driven by a motor-driven spindle 9 has connected thereto a slide 7 which carries magnetic instructing and reproducing transmission heads 11, 12. The frame 2 of the guillotine 1 supports one end of a magnetic tape 3, the other end of which is supported on a column 6. The head 12 is adjustable relatively to the head 11 by means of an adjusting screw 13. In operation, an electrical impulse is recorded on the tape 3 by means of the head 11. The back gauge 10 is then moved in the direction of the arrow until the head 12 coincides with the impulse recorded by the head 11. This has the effect of stopping the back gauge and the head 12 sends out an electrical impulse for effecting a cut. At the same time, the head 11 records a further impulse on the tape after the back gauge is again moved. The process is repeated until the programme of the magnetic tape is completed. The back gauge is then returned to its starting position and the head 11 switched off. The head 12 will stop the gauge drive at the individual information impulses corresponding to the cutting distances, whereupon the guillotine cutter is actuated. The cutter may be actuated mechanically, electrically or hydraulically.

Title: Multilayer Printed Circuit Board and Method for Manufacturing Same.
Inventor: MEYERS STEVEN CHARLES
IPC: H05K3/24
Filed: 1968-03-18
Abstract: 1,187,916. Printed circuits. CONTROL DATA CORP. 18 March, 1968 [26 June, 1967], No. 13110/68. Heading H1R. A multilayer printed circuit board is made by repeating the following steps; forming a conductive layer on an insulating substrate; covering the conductive layer with a suitable masking material; developing the mask according to the desired pattern of interlayer connectors; electroforming these connectors; removing the mask; and insulating the conductive layer and connectors. In a first embodiment the first of the multilayers of printed circuit is formed by photo-etching a layer of copper on an insulating substrate, Figs. 1, 2 (not shown), after which the exposed photoresist is removed and the printed circuit and exposed surfaces of substrate are coated with copper by an electroless or vacuum deposition process, Fig. 3 (not shown). The assembly is then coated with a mask which is photodeveloped in the pattern of interlayer connectors and conforms to the contours of the printed circuit pattern, Fig. 4. The electrolessly plated layer serves as an electrical path and permits the interlayer conductors to be built up by electroforming following which the mask and the resultant exposed electrolessly applied conductor are removed and replaced by a fibreglass epoxy insulating material, Fig. 5 (not shown). The top surface of the assembly is sanded to expose the top of the interlayer connector and then a second printed circuit layer is formed on the top surface by coating this surface with a thin layer of electrolessly deposited metal which serves as an electrical path for an electroforming step by which additional metal is plated on the coating and the printed circuit is formed as described above in connection with Figs. 1, 2 (not shown). A second electrical interlayer connector is formed as described above with reference to Figs. 3 to 5. If all of the interlayer connectors are connected to a first printed circuit layer the process does not require an electrolessly applied conductor for each layer. Thus the first layer is formed by electrolessly depositing a thin layer of metal on a substrate and electroforming interlayer connectors on it as shown in Fig. 4, but after the electroforming process, Fig. 9 (not shown), only the masking material is removed and replaced by an insulating material. A printed circuit layer is then formed by electroless and electroforming processes and an additional interlayer connector pattern is formed by an electroforming process, no additional electrolessly deposited layer over the second printed circuit being required. When the required number of layers has been formed the uppermost portion of the uppermost printed circuit layer is covered by insulating material, Fig. 10 (not shown), and the substrate and electrolessly applied conductive layer are removed by sanding. The etching steps may be replaced by electroforming processes.

IPC: H04L15/16
Abstract: 132,818. Wates, F. S. S. Nov. 17, 1917. Morse and like code multi-signal transmitting- arrangements. - A code signalling-transmitter comprises a multiple-position switch, a code commutator switch the brushes of which are connected to the contacts of the switch, a currentinterrupter operating to stop the commutator motor after the signal has been sent a predetermined number of times, and a switch for starting the motor after the arm of the multiple-position switch has been set to select the code. Each signal may consist of a letter and a numeral. In the arrangement shown in Figs. 2, 3, and 6, upon an arm 5, mounted on a spindle 2, is mounted in ball-bearings 4, a spindle 6 carrying an index arm 3 and an arm 7 carrying a ball 8. The ball 8 is pressed against a base 10 bv a spring 9, and the base 10 is provided with a number of split metal studs 11 the parts of which are insulated from each other and connected to commutator brushes a - - l and a<1> - - k<1> adapted to engage code contacts on a drum 12, Fig. 4. The code contacts are connected to the drum spindle 12', which is driven through gearing by a motor 13. An interrupter switch 17, consisting of a conducting- portion 18 and an insulating-strip 18', is placed in the circuit of the motor 13 by means of brushes 19, and the gearing is so arranged that the commutator drum 12 makes three revolutions for one revolution of the interrupter 17. A battery is connected across the terminals 20, 20', and the motor 13 is started by closing a switch 21. A lamp 23 is provided for indicating when signalling is taking place, and the currents may be relayed by an electro-magnetic switch 24. To effect a signal such as that corresponding to the split stud x<1>, the point of the index arm 3 is placed over the stud x<1> when the ball 8 bridges the two parts of the stud. The switch 21 is then closed to start the motor 13 by completing the following circuit : terminal 20, rheostat 22, motor 13, switch 21, and terminal 20<1>. The motor 13 rotates the drum 12 and the interrupter 18, 18<1>, so that when the switch 21 is opened, the motor circuit is completed through the conducting-pcrtion 18 of the interrupter. As the drum 12 rotates between the brushes a - - l and a<1> - - k<1>, the following circuits are made through the brushes g<1>, d connected to the two parts of the stud x<1> : terminal 20, spindle 12<1>, code contacts under the brush d, brush d, stud x<1>, and ball 8, arm 5, to spindle 2, where the current divides, part passing through the indicating-lamp 23 to contact 20', and part passing through the relay 24 to the contact 20<1>; a second circuit is established from the spindle 12<1>, code contacts under the brush g<1>, brush g<1>, stud x<1>, and ball 8, arm 5. to spindle 2, where the current divides as stated above. The arrawrement may be used for wireless signalling from aircraft to artillery, or for signalling from ships.
