Title: Improvements in machines for applying cream and the like materials to biscuits and the like
IPC: A21C15/00
Filed: 1927-09-01
Abstract: 300,335. Vicars, Ltd., T. & T., and Crosland, E. M. Sept. 1, 1927, Feeding articles from piles by pusher devices engaging their edges. - A machine for coating biscuits and applying cover biscuits to form sandwiches consists of a number of discs, preferably three, 1, 2, 3 revolving on vertical shafts 4, 5, 6 connected by a chain 8 trained over sprockets 7, the disc 1 acting as described below to place a biscuit in each of a number of carriers 9 carried on the chain 8, the disc 2 applying the coating material and the disc 3 acting in a manner similar to disc 1 to apply cover biscuits. Five. discs may be used to make a double sandwich having two coatings and three biscuits, or two discs applying different coating material may be positioned between two biscuit supplying discs. The sandwiches are discharged over a shoot 27 to a conveyer 28. The discs 1, 3 are each surmounted by a magazine 29, normally stationary but revoluble on the shafts 4, 6. The magazines receive a number of removable biscuit holders 18 having spring-retainers 30 which retain the bottom biscuits and the superposed piles when the holders are out of the magazine, but which are automatically retracted to allow the descent of the piles when the holders are inserted in the magazines 29. Since disc 3 acts identically with disc 1 the operation of the latter only is described. Only the holder 18 at the position B supplies biscuits and as the last biscuit is supplied, a projection 53 on a member 32 resting thereon engages a slot 68 in the disc 1 and the magazine is thereby rotated to bring the holder 18 at the position A into the supply position B. The projection 53 is then disengaged from the disc 1 by the member 32 engaging the bevelled edge of a plate 31 which is positioned above the disc 1 and beneath all the holders except the holder at the position B. The disc 1 has a number of openings through which the biscuits pass on to the carriers 9. The openings have a bevelled leading edge 49 and a square cut following edge 50 which permit the biscuits to fall gently on to a supporting plate 20 over which they are moved to the position C at which they are dropped into the carriers 9. The carriers 9 are pivoted on horizontal axes 10 and are raised at times by rollers 11 engaging with cam rails, to receive biscuits or coating material. The coating material is fed from a hopper 22. After the application of the cover biscuits, the sandwiches are ejected from the carriers 9 by rollers 23 contacting with another cam rail and lifting false bottoms of the carriers. In a modified form of carrier 9, the false bottom is pivoted upwardly when the roller 23 is lifted, by a roller on the false bottoms of the carriers. The carrier may be carried by one chain 8, or if more rigidity is desired, by two chains, one above the other.

Title: Improvements in and relating to automatic train stops
IPC: B61L3/18
Filed: 1921-08-31
Abstract: 188,825. Bonaccorso, O., and Lo Bue, G. Aug. 31, 1921. Electrical systems, automatic; track apparatus for stopping trains.-In an automatic train-stopping apparatus conductors divided into insulated sections are arranged longitudinally on the track and similar auxiliary conductors are arranged parallel to the first set; each section of the first set is connected to the next section ahead of the auxiliary set. The car carries a contact rolling on both sets and a dynamo which supplies a motor to operate the stopping mechanism. The throttle valve lever 1 has the usual quadrant 2 engaged bv a locking dog to hold it in position, and is attached to one end of a cable 8 wound on a drum 7 driven by the electric motor 4. The stem of the brake valve 3 carries a ratchet wheel 14 engaged by a pawl 16 driven through bevel gearing by the motor when the valve is operated by track conditions. The ratchet enables it to be operated manually at all times. A spring-controlled switch arm in the motor circuit normally engages a contact on the quadrant but is moved to break the circuit by a pin on the throttle lever when the lever is moved to the closed position. The dynamo 6 is driven by a wheel running on the track rail, and one of its brushes is connected to the conducting axle of the car wheels while the other brush is connected to the motor 4 and thence to the conducting wheel 28 as shown in the left hand part of Fig. 1. The connections for a train travelling in the reverse direction are shown in the right-hand part. The main and auxiliary conductors 31, 32 are insulated in sections by pieces 33 and a section 31<a> of the main conductor is connected by a transverse strip 31<c> to the next section of the auxiliary conductor. Where one train is overtaking another and approaches too closely, a circuit from the dynamo and motor of one train will be completed through the dynamo and motor of the other train, the track rails and the conductors 31, 32. Under danger conditions therefore the motor on the overtaking train will run to close the throttle valve and to operate the brake valve. The initial movement of the motor removes the lock on the throttle lever and further movement closes the valve.

Title: An improved process for the preparation of lithographic plates for printing
IPC: G03F7/04
Filed: 1937-08-26
Abstract: 501,069. Photo - mechanical printing- plates. HARRIS-SEYBOLD-POTTER CO. Aug. 26, 1937, No. 23452. Convention date, June 18. [Class 98 (ii)] In the preparation of lithographic printing- plates, the plate is coated with a solution containing a water-soluble halogenated polyvinyl alcohol. The sensitizing may be effected before or after coating. As sensitizers, ammonium chromate or bichromate or chromic acid may be used. Alternatively, organic chromates or bichromates, e.g. pyridine bichromate, urea-chromic acid and the reaction products of tetra-alkyl ammonium hydroxides or ethylene diamine with chromic acid may be used. Preferably the coating is applied in the presence of the same halogen as exists in the layer; for example by the use of a solution of the hypoacid in water. A water-soluble surface tension depressant, e.g. propyl or butyl alcohol, may be added to the coating' solution. Development may be effected with water, with alkylaryl ketones e.g. diphenyl heptadecyl ketone or with fatty acid amides, e.g. stearyl amide, and dissolution of the unhardened coating may be performed with #-glucono-lactone or gluconic acid. Heating of the plate to resinify the coating may be carried out 'after development. For example, zinc or aluminium plates may be heated for 15-30 minutes at 100 to 130 C.

Title: Improvements in or relating to machines suitable for use in painting lines on roads and other surfaces
IPC: E01C23/20
Filed: 1939-08-15
Abstract: 532,739. Line-markers for roads &c. HENDERSON, W. M. Aug. 15, 1939, No. 23505. [Class 132 (ii)] A machine for painting lines on roads or other surfaces is provided with a paintapplying roller which is so operatively connected with means for delivering paint to the roller that the paint supply is automatically initiated when the roller is applied to the surface to be painted, and is automatically arrested when the roller is disengaged from the surface. The machine is propelled by a hollow handle 29 and the paint from a container 6 falls through a row of rubber tubes on to the marking roller 9 which is provided with a deformable tyre of sponge rubber. When the marking roller is lifted off the road by raising the handle 29, a spring 26 actuates bell-crank levers 20 causing a bar 13 to nip the rubber tubes against a fixed bar and thereby cut off the feed of paint. On lowering the marking wheel on to the road a link 22 returns the bell-crank levers 20 against the pressure of the spring 26 to start the feed of paint. The extent of opening of the rubber tubes may be regulated by adjusting the position of the bell-crank levers 20 by means of a cam 28 rotated by a knob 31. A pointer 32 indicates on a scale the extent of the opening. A roller 37 may be provided on one or both sides of the marking roller to distribute the paint thereover.

Filed: 1973-05-17
Abstract: 1437817 Photographic apparatus MISOMEX AB 17 May 1973 [25 May 1972] 23544/73 Headings G2A and G2X A method of continuously, successively, or intermittently exposing a light-sensitive material in which the exposure value is changed from one portion to another of the exposure to compensate for secondary curing or fading of the latent exposed image/s. In apparatus for carrying out the above method exposure control means control the exposure value as a predetermined increasing or decreasing function of the time at which portions of the exposure occur. The exposure value may be changed by varying the length of exposure or the light intensity. The apparatus comprises a motor driven potentiometer R across which the total voltage is controlled by a manual potentiometer R 1  The output from potentiometer R is fed to a capacitor 3 which discharges through a circuit 5 when a switch 6 is closed by control means 4. During the time the capacitor discharges the lamp 9 is lit to expose the light-sensitive material 7. The time for which the capacitor discharges is determined by the amount to which it is charged. The output from the motordriven potentiometer R is continuously changing during an exposure cycle thus e.g. if its output voltage is decreasing the capacitor is charged to a lesser extent between each closure of switch 6 and its discharge time, and thus the exposure time also decreases.
