Title: Improvements in or relating to weighing apparatus
IPC: G01G13/00
Filed: 1933-07-18
Abstract: 422,789. Weighing-apparatus fitted to cigarette-making machines. MOLINS, W. E., 2, Evelyn Street, Deptford, London. July 18, 1933, No. 20253. [Class 143] [See also Group VI] In apparatus more particular for checking at predetermined intervals, the weights of cigarettes delivered from cigarette - making machines and in some cases for controlling the tobacco feed to the machine, a batch of charges each comprising a plurality of cigarettes to be weighed is disposed in a plurality of compartments connected to a weigh beam and, between successive weighing operations, one compartment is emptied and a new charge placed therein or in another empty compartment, and the compartments are emptied in rotation. By thus spreading out the selection of the batches to constitute the test weighing, a fairer average is obtained. The cigarettes are automatically lifted at intervals by a deflecting flap 1 and delivered by a fluted wheel 2 to a compartmented drum 3. The drum has four compartments 4-7 and is intermittently rotated by a link and pawl device so that after the compartment 4 has received its charge the next compartment 7 is brought into receiving position and after a predetermined interval receives a similar charge. The next pocket 6 similarly receives a charge to complete the batch and the weighbeam is automatically released and the test weighing takes place. After the weighing, the drum rotates again and the cigarettes in the lowermost pocket fall out on to a band 23, and before the drum rotates again a further charge of cigarettes is delivered into the empty compartment at the receiving position. In each compartment is a shockabsorbing pivoted flap 20 on to which the cigarettes from the wheel 2 fall in passing to the bottom of the compartment. A shield 21 near the lower portion of the drum retains the cigarettes until they reach the discharging position where they accumulate upon, and tilt a flap 22 before running on to the band 23.

Title: Improvements in or relating to multi-party signalling systems
Inventor: SCOWCROFT JOHN
IPC: H04Q5/06
Filed: 1952-08-12
Abstract: 749,998. Party-line systems. GENERAL ELECTRIC CO., Ltd. June 12, 1953 [Aug. 12, 1952], No. 20287/52. Class 40 (4). On an eight-party-line, Fig. 1, a particular substation is selectively called by the application of a relatively high potential of a particular polarity to a particular line wire together with the application of an alternating potential to one or other line wire, causing the firing of gas tubes G and the operation of relays A at two substations and the ringing of bell B at one of them. On a sixteen-party-line, Fig. 2 (only eight parties being shown), each substation has an additional relay B and the additional calling condition consists of a relatively low potential of selected polarity applied to that line wire which is not carrying the relatively high potential. The removal of the relatively high calling potential leaves the ringing circuits at all the substations in a non-conducting condition.

Title: Manufacture of artificial products
IPC: C08G12/12
Filed: 1928-07-13
Abstract: 293,872. Kappeler, H. July 14, 1927, [Convention date]. Samples furnished. Urea-furfurol condensation products. - Black compositions resembling ebonite are produced by condensing furfurol with urea and conducting at least a part of the reaction in the presence of an acid or acid salt. The furfurol mav be mixed with other aldehydes and the urea with other amino compounds; furfuramide or derivatives and condensation products of urea may also be used. The reaction may proceed in stages, furfurol and urea being first brought together without a catalyst or in presence of a neutral or alkaline substance, and then converted into the final product by addition of an acid electrolyte or ammonium salt. Colouring matters, filling materials and softening agents may be added, e.g. mineral pigments, organic dyestuffs, sawdust, cork powder, leather powder, heavy spar, asbestos, glycerine, camphor, naphthalene, ketones, phenols, amines or their condensation products with, for instance, formaldehyde. The compositions may be after-treated with an impregnating agent, whilst the mixture made for the purpose of the reaction may be used for impregnating wood, cellulose, &c., before the reaction is completed. According to examples, (1) approximately equimolecular proportions of urea and furfurol are mixed in the presence of aqueous hydrochloric acid and the liquid poured into moulds which are preferably cooled to modify the ensuing reaction: finallv the mass is heated to 100‹ C., forming a solid, black composition which can be rendered tougher by boiling with an impregnating agent such as linseed oil or furfurol; the water may be replaced wholly or in part by alcohol, glycerine or acetone, and the acid by another mineral acid, an organic acid or an acid salt; (2) the urea of the preceding example may be replaced by a mixture of urea with aniline or toluidine or by a salt of urea such as the hydrochloride, whilst a mixture of furfurol or formaldehyde may replace the furfurol; (3) urea and furfurol or furfuramide are heated together to 100‹ C., if desired in the presence of alcohol or water; the yellowish product is further heated after addition of hydrochloric acid or a salt such as ammonium chloride for conversion with the black final material; (4) urea and furfurol are heated to 100-120‹ C. in presence of a base such as caustic soda or a basic salt: the resulting soft, soluble resin is then condensed bv means of hvdrochloric acid into the black composition. Specification 256,711 is referred to.

Patent GB-863578-A (GB)
Title: Improvements in or relating to the preparation of graphitic oxide from graphite
IPC: C01B31/00
Filed: 1957-06-28
Abstract: Graphitic oxide is produced by the oxidation of graphite using a mixture of sulphuric acid, an anhydrous inorganic nitrate and an anhydrous inorganic permanganate containing less than 1% wt. water. The inorganic nitrate may be NaNO3, KNO3, Ba(NO3)2, Ca(NO3)2 or Mg(NO3)2 and the inorganic permanganate NaMnO4, KMnO4, Ba(MnO4)2, Ca(MnO4)2, Mg(MnO4)2.  In operation, graphite, e.g. ceylon graphite, may be contacted, a small portion at a time, with a mixture of sulphinic acid, e.g. in amount 22 ml/gm of graphite, NaNO3 in amount 1/20 -\ba1/50th part by wt. of the graphite and KMnO4 in amount 1/10 -\ba1/7th part by wt. of the graphite at a temperature of 25-45 DEG preferably 35 DEG C. for 1/2 -1 hour.  Alternatively, the graphite may be admixed with sulphuric acid and the anhydrous nitrate and the anhydrous permanganate subsequently added gradually to the mixture. Either method may be operated as a batch process and the former also as a continuous flow by passing the oxidising mixture and graphite through cooling coils at the required temperature.  When the graphite has been substantially oxidised, e.g. the degree of oxidation is such as to have produced a product having a C:O atom ratio of 3.4 or less, the product can be obtained by diluting the reaction mixture with water, removing the suspended graphitic oxide by decantation, centrifuging and subsequently dialyzing out the acids and salts therefrom.  H2SO4 residues may be recovered, concentrated and re-used.

Abstract: 1,248,813. Counters. TELRAD TELECOMMUNICATION & ELECTRONIC INDUSTRIES Ltd. 25 April, 1969 [15 May, 1968], No. 21239/69. Heading G4A. [Also in Divisions H3-H5] A ringing selector for an interconnection system includes a slipping counter 11 having a number of stages S0-S10 each associated with a telephone extension and connected thereto through an output transistor TR1-TR10. The input to the counter includes the telephone dial contacts 1 and an additional series-connected switch 2/2 which is operated to seize the device so that the dial impulses cause the counter output to be stepped the required amount. When the dial returns to normal the respective output transistor is enabled to apply a calling signal to the required extension. In operation cradle switch 2/1 and additional switch 2/2 are closed which causes transistor 7 to bring up relay 10 after capacitor 8 has charged up. The contacts of relay 10 prepare counter 11 and prepare the circuit associated with transistor 19. Dialling pulses are transmitted and the output of counter 11 steps until the base of the required output transistor TR1-TR10 is marked. When the dial returns to the rest position capacitor 15 is charged up until transistor 19 conducts to apply an operating potential to the emitters of transistors TR1-TR10 so that the marked transistor conducts and sounds an audible alarm at the respective telephone extension. After a time delay capacitor 8 discharges causing relay 10 to drop out and the device to reset to its initial state. The device is stated to be completely independent of the speech path circuitry.

Abstract: 1,152,294. Collapsible steering columns. GENERAL MOTORS Ltd. 2 May, 1968 [8 May, 1967], No. 21365/67. Heading B7H. In a vehicle steering column assembly in which a steering shaft 10 is collapsible telescopically in response to abnormal impact forces on a vehicle steering wheel, an upper portion 12 of the shaft 10 has a thrust bearing connection 16 to a telescopically deformable member 20 which is deformed as the shaft 10 collapses telescopically, and in the region of the connection 16 the deformable member 20 is connected to a support 42 by at least one mounting member 44, 46 which breaks away in response to an abnormal impact force on the steering wheel and thereupon constrains the part of the deformable member 20 in the region of the connection 16 to move in a direction oblique to the longitudinal axis of the uncollapsed steering shaft. The deformable member may extend coaxially of the steering shaft 10 (Fig. 1) or obliquely of the shaft (Fig. 6, not shown). The steeling shaft comprises upper and lower portions 12, 14 interconnected by shearable pins 30, which are preferably of plastics material injection-moulded in situ, and is pivotally mounted either on a toeboard at the lower end, preferably by a resilient bushing 28, or to the front firewall by a generally upright link (50) (Figs. 3, 5, not shown). The mounting members 44, 46 are secured to the support 42, of H-crosssection, and mounted in open-upper-ended slots in a bracket 40 secured to the deformable member 20, in which slots they are slidable after their frangible connections with the support have broken upon impact. These frangible connections are preferably of in situ injectionmoulded shearable plastics material. Engagement of the portion 48 of the bracket 40 with the support 42 prevents rearward movement of the steering column assembly in an accident.
