Abstract: 1275633 Stitching apparatus HARRIS-INTERTYPE CORP 3 June 1969 [18 June 1968] 28111/69 Heading B4C [Also in Division B8] General.-Sheets are separated from a number of piles 34 (only one shown) by suction devices 70 and collated to form stacks on a surface 36 along which the stacks are moved by pusher members 38. Each completed stack is transferred by a reciprocatable shuttle assembly 46 to a stitching station 48. The stacks are registered against stops 134, stitched by members 94 and 96 and forwarded to a folding and cutting assembly. Feeding sheets; pusher feeds, reciprocating grippers, registering.-Suction devices 70, provided above each stack, are simultaneously moved on a bar 80. Pusher members 38 carried on endless chain 84 are lowered beneath the surface 36 as the stacks are moved away by the reciprocatable shuttle 46. The shuttle, provided with upper and lower clamping bars takes-over each successive stack from pusher members 38, accelerates a gripped stack to a position beyond collapsible stop member 134 and then returns to register the stack by its originally trailing edge against the stop, whereupon the shuttle releases the stack and returns to grip the next succeeding stack. A pressure roller 140 holds each stack in the register position. The relationship between pusher members 38 and the shuttle 46 is adjustable so that a stack may be registered with its centre line or with its originally trailing edge beneath stitcher members 94 and 96. Stop 134 is also adjustable for this purpose. Folding and stitching apparatus.-Stitcher heads 94 and 96 supplied with wire from reels 160 are adjustable along bar 156 and movable on bars 152, 154 into engagement with the stacks. One of the heads may be rendered inoperative to permit corner stitching. Following the stitcher assembly is a buckle folding unit 60 having a folding pocket 300 which may be blocked-off by a guide 320 to prevent an edge stitched stack being folded. The folded stacks are trimmed by a blade 62. Unfolded stacks are passed directly to conveyer 324. The folder is operated at a speed greater than the shuttle assembly 46 to move a stack from beneath the stitcher heads before the shuttle brings the next stack into position.

IPC: E21B49/00
Filed: 1975-07-03
Abstract: 1510886 Method for drilling and completing wells in unconsolidated formations G O SUMAN 3 July 1975 [23 Sept 1974] 28144/75 Heading E1F A method for drilling and completing a well having a borehole involves the determination of the minimum pressure which must be exerted against the formation in the borehole to maintain a relationship between the radial effective stress and the maximum principal effective stress of the formation such as to prevent formation failure over at least the first region of the Mohr failure envelope. Either this relationship is such as to maintain the Mohr circle within the failure envelope over at least this region, or the relationship is as defined by (1-sin alpha) divided by (1+ sin alpha) where alpha is the angle of internal friction for such formation. Drilling mud maintains the minimum pressure while the borehole is formed, a string of casing 20 is run in and an inflatible packer 21 is employed so that the pressure can be maintained while cement 22 is introduced. The cement is put down the outside of the deflated packer then the packer is inflated with cement. Finally holes 31 are formed when the cement has set.

Title: Improvements in and relating to relays for poly-phase circuits
IPC: H01H83/14
Filed: 1923-11-10
Abstract: 211,834. Measurement, Ltd., (Assignees of Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz). Feb. 22. 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Induction relays for the protection of polyphase currents. A disc 4 is acted upon by the currents in such a manner that when the balance between the phases is disturbed, as for example by a short circuit or a more or less complete break in the wire of one of the phases, the disc is rotated and closes the circuit to a circuit breaker. In the case of a three phase circuit without a return wire, there are three electromagnets 1, 2, 3 each energized by two windings. The one winding has a preponderant self-inductance and the other a preponderant resistance, and the circuits are arranged as shown in Fig. 1 with the inductance winding of one magnet in parallel with the resistance winding of an adjacent magnet. The difference in phase 4 between these two windings that are in parallel may be varied by means of an adjustable resistance 5, 6 or 7. If the balance between the three phases is disturbed, so that the current in one phase is I2 and that in each of the other phases is I1, then the resulting torque on the disc 4 is shown in Fig. 2 as a function of I1-I2 for different values of #. If the resistances 5, 6, 7 are adjusted so that #=54‹.5 for example, there is a negative torque on the disc 4 when the system is balanced. If the balance is disturbed so that I1-I2 becomes @@@@@@ greater than 0.4 or less than -0.5 the torque becomes positive. The disc 4 may be influenced by a spring so that the relay is not actuated for very feeble currents, or alternatively so that the relay will be actuated when two phases are simultaneously interrupted and there is in consequence no electromagnetic torque. Fig. 3 shows a practical form of the relay. The metal disc 8 rotates under the action of three electromagnets each of which has an inductance winding 12 and a resistance winding 14. In series with the resistance windings are resistances 16 adjusted by the knob 18.

IPC: C07D317/72
Filed: 1952-12-19
Abstract: The invention comprises dodecahydrophenanthrenes of the formula <FORM:0763207/IV(b)/1> wherein the 7-position is substituted by a bivalent group convertible to keto by acid hydrolysis or by a pair of univalent groups together convertible to a single keto group by acid hydrolysis, and decahydrophenanthrenes of the formula <FORM:0763207/IV(b)/2> wherein the 7-position is substituted by a univalent group convertible to keto by acid hydrolysis, and the preparation thereof by oxidizing the corresponding 1,4-dihydroxy-compound with an aluminium alkoxide, e.g. aluminium isopropoxide, in the presence of a ketone, e.g. acetone, methyl ethyl ketone, cyclohexanone, benzyl and p-benzoquinone, preferably in the presence of an inert solvent, e.g. benzene, toluene and dioxane, or with chromium trioxide.  This process may be modified in that the 1,4-dihydroxy-compound is prepared by a process claimed in Specification 763,208.  An alternative process claimed for the preparation of the above compounds comprises oxidizing the corresponding 1 - hydroxy - 4 - keto - or 1 - keto-4-hydroxy-compound with chromium trioxide.  The 1-keto-4-hydroxy-compound may be obtained as a by-product in the oxidation of the 1,4-dihydroxy-compounds referred to above, and the 1-hydroxy-4-keto-compound may be obtained as a by-product in the oxidation with chromium trioxide of the 1,4-dihydroxy-compound, for example, prepared by the process claimed in Specification 763,208. The 1-hydroxy-4-keto-compound used above may also be obtained by selectively acylating the corresponding 1,4-dihydroxy-compound to form a 1 - acyloxy - 4 - hydroxy - compound, e.g. with acetic anhydride and pyridine, which is then oxidized with a pyridine-chromium trioxide complex to form a 1-acyloxy-4-keto-compound and subjecting this compound to alkaline hydrolysis, e.g. with methanolic potassium carbonate, two stereoisomers are obtainable, one is obtained by a mild hydrolysis, and the other by the use of more vigorous conditions such as a prolonged reaction period and/or larger quantities of potassium carbonate.  The 7-position of the compounds of the above formul  may be substituted by a cyclic ketal or a cyclic thioketal such as an ethylenedioxy, ethylene dithioketal or ethylene hemithioketal group in the case of a bivalent group convertible to keto by acid hydrolysis, a non-cyclic ketal such as dimethyl ketal in the case of a pair of univalent groups together convertible to a single keto group by acid hydrolysis, and an enol ether group such as ethyl enol ether in the case of a univalent group convertible to keto by acid hydrolysis.  The preferred compound is 4b-methyl-1,4-diketo-7-ethylenedioxy - 1,2,3,4,4a,4b,5,6,7,8,10,10a-dodecahydrophenanthrene which may be obtained in three stereoisomeric forms having the melting points 117-121 DEG  C., 171-172 DEG  C., and 146-148 DEG  C.
