Title: Control for a Ramming Hammer with Hydraulic Drive
Inventor: CORDES HUGO
IPC: E21B1/26
Filed: 1967-06-29
Abstract: 1,159,465. Hydraulic reciprocating motors. H, CORDES. June 29, 1967 [July 6, 1966], No. 30044/67. Heading F1A. A hydraulically-actuated ramming hammer for driving piles, smashing or compacting, comprises a hammer block 5 reciprocated by a differential piston 3 through a hollow piston rod 6, pressure liquid being continuously supplied to the underside of the piston via passages 9 and 10, and the upper side of the piston being alternately connected to pressure and exhaust by a valve 8, compressedair-loaded hydraulic accumulators 13, 17, being provided in the inlet and outlet connections to assist the downward stroke of the piston, and to damp pulsations in the outlet line, respectively. In the Fig. 3 embodiment, valve 8 is carried by a rod 7 slidable in piston 3 and in the upper housing. As piston 3 moves upwardly from the position shown, parts 11 in rod 7 are closed and liquid is displaced from hollow piston rod 6 through the passage 18 and upper parts in rod 7 to move a differential piston 24 upwardly, until it engages an adjustable stop 28. Further movement of piston 3 then causes rod 7 to move upwardly by the pressure developed in piston rod 6 acting against the supply pressure on piston 29, thereby causing valve 8 to connect the pressure supply to cylinder 12 above piston 3. The piston 3 continues to rise and pressurizes accumulator 13 via inlet 9, the pressure in piston rod 6 also moving piston 21 upwardly to further pressurize accumulator 13. When piston 3 commences its downward stroke, assisted by the pressure in accumulator 13, piston 21 returns to its lower position, and piston 24 moves downwardly until its lower portion closes bore 26, passage 30 being closed due to the upper position of rod 7. When piston 3 has moved sufficiently downwardly, the reduced pressure in piston rod 6, and the supply pressure acting on piston 29 and/or a spring, causes rod 7 to move downwardly to reverse valve 8, and passage 30 then being opened to permit piston 24 to move to its lower position. Adjustment of stop 28 varies the upper limit of the piston stroke. In the Fig. 4 embodiment, valve 8 is actuated against spring 33 by a piston 32 subjected to the pressure in piston rod 6. Rod 7 is held stationary by an adjuster 31, which provides axial adjustment of rod 7 to vary the lower limit of the piston stroke. The ramming hammer may be mounted on the cantilever of a mobile building machine, Fig. 1 (not shown), or may be suspended from a crane jib for piling, Fig. 2 (not shown).

Abstract: 1,117,232. Buttering and filling bread rolls. J. A. CADWALLADER. 29 Oct., 1965 [29 July, 1964], No. 30102/64. Heading A2A. [Also in Division A4] A method of preparing a filled bread roll comprises forming a cavity in the roll, inserting tubular means containing the filling (e.g. butter and/or savoury filling in the cavity and discharging the filling into the cavity as the tubular means is withdrawn. The tubular means may comprise two tubes arranged side by side or two concentric tubes, each tube containing a separate ingredient of the filling. The cavity may be formed by two reciprocating knives disposed side by side or one above the other. More than one roll may be done simultaneously the rolls after filling may be sliced and fried. The filling may be heated. The roll 7 is supplied on conveyer 6 to knives 1, 2 which are inserted in the roll 7 and vertically separated by roller 4 to form the cavity in the roll. Knife 1 engages the lug of insert 14 formed from tubing 8 by punching, sealing and cutting means 9. Knives 1 and 2 are withdrawn from the cavity and insert 14 is pulled into the cavity. The roll is sealed in package 7<SP>1</SP> till it is filled. The roll 7 is clamped in clamp 28 for filling and the insert 14 is attached to one end of a pair of tubes 21. On withdrawing insert 14 from the cavity the tubes 21 are pulled into the cavity. When the tubes 21 are fully in the cavity the ring 27 severs the tubes 21 as label 26 is not able to pass through apertured plate 30. As the tubes 21 are withdrawn from the cavity they are squeezed by pressure rollers 29 and the filling is discharged into the cavity.

Title: Improvements relating to electro-mechanical movements for clocks
IPC: G04C3/04
Filed: 1967-06-30
Abstract: 1,134,790. Electric clocks. W, STAIGER [trading as GEB. STAIGER]. June 30, 1967 [July 13, 1966],No.30243/67. Addition to 1, 085, 605. Heading G3T. [Also in Division H1] An electro-mechanical movement for a clock comprises a balance 88' driven from a moving coil 60 by a contact arm 302 which, together with a driving spring 80 which also co-acts with the balance, is carried by a body 58' supporting the moving coil and is initially loaded towards a stop pin 82 on the body, the contact arm being a rigid arm pivotably mounted on a pin 304 attached to the body and acted upon by a spring 316, the tension in which remains approximately constant during deflection of the contact arm. The coil embraces a permanent magnet (not shown) having a yoke 44 and the body is acted on by a restoring spring (not shown) which tends to rotate the body in a counter-clockwise direction aginst a stop (not shown). The contact arm 302 is eccentrically mounted on a member 306 which has an adjusting slot 310 and the spring 316 engages a notch 314 in a lever arm 312, integral with the contact arm. Several notches are provided to allow adjustment of the force exerted by the spring on the contact arm which adjusts the amplitude of the balance oscillation. One end of the coil is connected through the restoring spring to one terminal of a current source whilst the other end of the coil is connected to the contact arm 302, the other terminal of the current source being connected to a contact 320 on the balance. Initially the spring 80 and the contact arm lightly engage a pin 82, but on starting the clock so that the balance moves in a counterclockwise direction, for example, the contact 320 first engages the spring 80 so that the balance rotates the body 58' in a clockwise direction until the contact 320 engages the contact arm 302. The circuit is therefore completed and the body then turns faster than the balance until the body engages a stop (not shown) The balance is rotated by the contact arm 302 until the arm organ engages the pin 82 whereupon the contact between the arm and the contact 320 is broken. The coil and body therefore return to their initial position and the balance subsequently rotates in a clockwise direction, the contact 320 moving aside the spring 80. The balance continues its clockwise rotation before the cycle recommences. Since the tension in the spring 316 remains approximately constant during the working stroke of the body, the impulse received by the balance from the contact arm is constant and independent of variations in the supply voltage. The movement of the body drives a seconds wheel by a pawl device (not shown).

Title: Improvements in or relating to the manufacture of alkali metal silicate compositions
IPC: C01B33/32
Filed: 1948-11-22
Abstract: A readily-soluble, substantially anhydrous silicate composition is produced by heating a mixture of a hydrated alkali metal, particularly sodium, silicate, at least as acidic as the meta-silicate and which in the solid state is fusible, and an inert water-soluble alkali metal salt of another acid at 100-200 DEG  C. until the loss of weight of a sample when heated to a temperature near to, but below, the softening point of the dried material is less than 5 per cent, the said salt being used in amount sufficient to maintain a porous mass throughout the reaction period, say, not less than 50 per cent by weight of the alkali metal silicate.  The alkali metal salt may be the carbonate or bicarbonate, sulphate, chloride or mono-, di- or triphosphate, or the previously produced dried silicate composition.  An acidic alkali metal salt may also be present. Drying may be effected in a rotating drum.  A cleansing and disinfecting composition may be produced by mixing the dried silicate composition with calcium hypochlorite or bleaching powder.

Title: Improvements in or relating to the manufacture and use of nutrient solutions for accelerating the germination and/or growth of seeds and plants
Filed: 1931-11-02
Abstract: The germination or growth of seeds or plants is accelerated by means of a nutrient aqueous solution containing a nitrogen acid and organic matter.  A solution described by way of example contains lime, sugar, potassium phosphate, nitric acid, urea and boron or manganese.  Other ingredients mentioned for solutions suitable for treating particular kinds of seed are chlorate of manganese, ammonium sulphate, ammonium phosphate, potassium silicofluoride, potassium chloride, calcium phosphate, calcium nitrate, magnesium sulphate, ferrous sulphate, iodine or iodides, citric acid, and artificially produced degradation products of albuminous bodies of animal or vegetable origin, such as meat, casein, lactalbumin, or oil-free plant seeds, particularly seeds of the same kind as those for the treatment of which the nutrient solution is intended.  Preservatives, for example salicylic acid and formaldehyde may be added to the solution.  The composition of solutions specially suitable respectively for the treatment of maize, lupines, soya beans, oats, and rye is described.  For treatment, the seeds are arranged in a thin layer, covered with the solution and subsequently irrigated periodically with reduced quantities of the solution.  Before irrigation the seeds may be subjected to irradiation, for example by rays from a quartz lamp. During irrigation air and light may be excluded and air may be replaced by a gas containing nitrogen or carbon.  The whole product may be used as fodder for animals.  Green vegetables for human consumption may be grown in this way.  It is stated that the composition of the solution will influence the composition of the product.  For example, in order to obtain high contents of phosphorus, iron or iodine in the product, compounds of these elements should be present in the solution.

Abstract: 357,393. Fire - - extinguishing sprinklers. GRIFFITH, W. B., 263, Whitehorse Pike, Audubon, New Jersey, U.S.A. Oct. 10, 1930, No. 30406. [Class 47 (ii).] An accelerator for dry-pipe sprinkler systems comprises a casing 12 divided by a diaphragm 18 into a compartment 20 connected to the sprinkler piping 27 by a pipe 26, and a compartment 22 connected to the neutral chamber of the dry-pipe valve 28 by a pipe 34. A spindle 40 passing through the diaphragm 18 carries at its lower end a valve 36 that normally seals a main air outlet 30 from compart. ment 20. The valve is carried on the spindle by a sleeve 60 and is urged downwardly by springs 65, 66. The compartments communicate by way of a passage 48 in the spindle 40, which passage has a restricted vent 51 adjustable in size by means of a screw 56 carried by a pivoted arm 55. Compartment 22 has an air outlet 33 sealed by a pivoted clapper 73. A lever 78 pivoted at 8 to the spindle 40 has fingers 85, 86 for engaging lugs 76 on the clapper 73. Springs 88 are connected to the end 80 of the lever 78 and to points 91 on a collar 89 adjustable along the spindle 40. Fig. 1 shows the position with the system in the ready condition, pressures in the piping 27 and compartments 20, 22 being equalized through the vent 51, the valves 36 and 73 being closed, and the lever 78 being held by its springs 88 with its fingers 85 in locking engagement with the clapper 73. When a sprinkler head opens, pressure falls more quickly in compartment 20 than in compartment 22, the diaphragm 18 moves down with the spindle 40, and the lever 78 turns about its pivot with the fingers 85 as fulcrum. When the end 80 of lever 78 moves to the right of the line through points 91, 81, the springs 88 turn the lever rapidly clockwise, causing the fingers 86 to open the clapper 73. Pressure then falls rapidly in compartment 22, the diaphragm 18 moves upwardly, and the valve 36 opens, Fig. 5, rapidly exhausting the air from the sprinkler system. In a modification, Figs. 6-8 (not shown), the latch lever 78 is pivoted to the valve body 33, and has a lug engaged by an adjustable collar on the spindle 40.

Abstract: 1,081,788. Collapsible steering columns. GENERAL MOTORS CORPORATION. July 7, 1966 [April 29, 1966], No. 30469/66. Heading B7H. [Also in Division F2] In a collapsible motor vehicle steering column, a support jacket 30 having rotatably mounted therein a steering shaft 26 arranged to telescope under axial load includes a collapsible portion 100 which undergoes plastic deformation under load to absorb axial impact, a lower support assembly connects the jacket 30 to a firewall of the vehicle so as to permit only limited axial movement of the lower part of the jacket relative to the firewall, and an upper support assembly connects the jacket 30 to a fixed body member spaced from the firewall so as to permit axially downward movement of the upper part of jacket but prevent axially upward movement. A transmission selector tube 28 extending through the jacket 30 coaxially with the steering shaft 26 also telescopes under axial load. The collapsible portion 100 of the jacket 30 comprises a network of intersecting strips (Fig. 2, not shown) formed by making diamond-shaped perforations in flat sheet from which the jacket is subsequently formed, and includes a number of radial bulges which promote collapse in concertina fashion. The lower support assembly includes a plate 34 which is bolted to the firewall and includes an arcuate collar 40 (Fig. 4, not shown) clamped by a strap to the jacket 30. Projections 48 (Fig. 3, not shown) on the jacket 30 are spaced on either side of the collar 40 to engage therewith and limit axial movement of the jacket under axial loads sufficient to overcome the friction between the collar 40 and jacket 30. The upper support assembly comprises a mounting strip 52 fastened to the jacket 30 and positioned against a fixed support 20 (Fig. 5, not shown) by hanger bolts 56. Slots in the strap 52 permit downward displacement of the strap on the bolts 56 under axial load. The steering shaft 26 comprises an upper shaft part 84 which is connected to the hub 86 of a steering wheel 88 and journalled in a bearing block 80 mounted in the jacket 30, and a lower tubular part 90 which is connected by a flexible coupling 96 to a steering box and journalled in a bearing block 76 fixed to the jacket 30. Flattened portions of the shaft part 84 and tubular part 90 engage to transmit the steering torque, and plastics pins 92 moulded in recesses in the shaft part 84 and aligned apertures in the tubular part 90 shear to permit the parts to telescope under an axial load which is less than that required to collapse the jacket 30. The transmission selector tube 28 comprises an upper section 66 connected to a hub 62 on a selector barrel 64 which is rotatably supported by the block 60 and carries a selector lever, an intermediate section 68, and a lower section 70 rotatably mounted in the block 76 and connected to a selector arm 78 linked to the transmission. Plastics keys 72, 74 moulded in slots and aligned apertures in the respective sections shear to permit the sections 66, 68, 70 to telescope under axial load.
