Title: Improvements in propeller pencils
IPC: B43K21/12
Filed: 1931-07-18
Abstract: 369,501. Pencil holders. EGERTON & CO., Ltd., J. and MORGAN, H., Royal Ensign Pencil Works, Camp Street, Broughton, Manchester. July 18, 1931, No. 20607. [Class 146 (iii).] In a propelling-pencil a frictional clutchdevice for allowing over-winding is provided within or adjacent to the end portion of the pencil, and permits the lead-projecting machanism to be rotated in either direction indefinitely. The usual slotted lead-holder 1 and the lead ejector are provided with pins 2a which are guided in a helical groove in the part 2. To the part 2 is attached, by a pin and slot arrangement, an externally screw-threaded collar 3 to receive the outer casing 4 of the pencil. An extension 5 of the holder 1 carries an intermediate part 6, recessed at each end, which abuts against the collar 3. A coil-spring 10 mounted on the extension 5 abuts against a loosely mounted washer 8 in the recess 7 of the part 6 and a rigid abutment 9 on the extension 5. A conical end portion 11 is attached rigidly to the extension 5 by screw means or spotwelding so that the spring 10 is compressed. If the intermediate part 6 is held the casing 4 can be rotated in either direction to actuate the lead-ejecting mechanism until the limit of motion of this mechanism is reached, when continued rotation of the casing 4 overcomes the frictional resistance of the intermediate part 6 with the conical end 11 and the collar 3, which is due to the resistance of the spring 10, and all the rest of the parts of the pencil rotate together. The grinding of the faces of the parts 3, 6, 11 during overwinding gives an audible signal. In a modification the clutch-device is situated near the front end of the intermediate part, and the spring is arranged in a recess between the end part and the intermediate part.
Patent GB-899148-A (GB)
Title: Improvements in or relating to the production of organosilicon polymers
IPC: C08G77/00
Filed: 1960-06-10
Abstract: An organosilicon polymer of the formula <FORM:0899148/IV (a)/1> p  is made by reacting R2SiX2 with water and H2SO4 in the proportions represented by the overall equation:-(n+2m+2)R2SiX2+ --> (n+m+1)H2O+m(H2SO4) polymer of the above formula, wherein each R is a substituted or unsubstituted hydrocarbon radical, each X is a halogen atom or an alkoxy radical, and n and m are numbers which may be fractional when the formula represents an average formula of a mixture of polymers. The process may be carried out in one stage or in several stages with equilibration of the resulting intermediate products, e.g. (a) in a first step (n+m+1) moles of R2SiX2 are reacted with (n+m+1) moles of water; (b) in a second step m moles of R2SiX2 are reacted with m moles of H2SO4; (c) in a third step the reaction products of (a) and (b) are reacted with 1 mole of R2SiX2 and equilibrated by heating to 150 DEG C.  Thus the starting materials may include one or more compounds which may be obtained by the reaction of the silane with water and/or sulphuric acid, such as pure cyclic or chain polysiloxanes and their silyl sulphates, e.g. <FORM:0899148/IV (a)/2> which may also be obtained by reacting diakyl siloxanes with chlorosulphonic acid.  In examples dimethyl-dichlorosilane is reacted with sulphuric acid and water in the above proportions to yield viscous oils.

Small, spherical beads of substantially identical size and composition and containing at least one pharmaceutically or biochemically active ingredient are prepared by allowing drops of a solvent or solvent mixture to fall on a bed of finely divided polymer which is readily soluble in the solvent. The spherical beads formed are screened out of the bed subsequently and dried. Specified polymers are: cellulose acetate phthalate, carboxy polymethylene and carboxylated polyvinyl acetate co-polymers. The active compound, which may be present in the solvent or the polymer bed, may be a medicament such as a tranquilizer, antihistamine, steroid, anorectic, antibiotic, decongestant, antitussive, antichlorinergic, antibacterial or antifungal agent many examples of which are specified. Alternatively, it may be an agricultural chemical such as a herbicide e.g. phenyl mercuric acetate. The polymer bed may also contain a "cosubstance" which becomes entrapped in the beads and modifies their properties (particularly rate of release of the active substance). The "cosubstances" used are film-forming aluminium salts. When the active ingredient forms such an aluminium salt, this salt is used; when it is not, aluminium aspirin is used. Other aluminium salts mentioned are aluminium abietate, naphthenate and octoate.

Title: Improvements in flat work ironers
IPC: D06F65/10
Filed: 1924-09-08
Abstract: 241,350. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Sept. 8, 1924. Ironing-machines with rollers rotating against concave surfaces.-In an ironing-machine in which several rollers coact with corresponding troughs in a heated bed, means are provided for supporting the rollers in ironing position either with or without pressure on the corresponding beds. The means are arranged so that all the rollers are in the pressure-free or pressure-applying position at any time, but the pressure applied may be varied on each individual roller when they are in the pressure applying position. Means associated with each roller also are provided to indicate the degree of hardness existing in the padded covering of the roller and to indicate the pressure applied. The spindle 11 of each roller 12 is carried by a bearing block 9 sliding in a recess 4 in the main frame 1. A rod 16, shouldered at 24, extends upwardly from each block and carries collars 27, 31 splined thereto and a collar 25 integral therewith. A spring 26 is supported between the collars 27, 25 and another spring 33 is supported between the collar 31 and a nut 34 carried by a web 23. The rods 16 extend into the upper housings 17 of an inverted troughshaped frame 14 which carries the webs 23, one of these frames being provided at both ends of the rollers. The frames are raised and lowered by rods 64, 65 actuated from cam-shafts 68, 69. In 'the position shown in Fig. 3, the rotation of the hand-wheels 21, and consequent compression of the springs 26, does not result in ironing pressure being applied to the rollers 21, since the force of the compressed springs 26 is neutralized by the springs 33 so that the rollers float without pressure on the beds 8. To render ineffective the neutralizing action of the springs 33, so that the rollers may be operated with ironing pressure applied, there is provided a rod 42 having collars 41 which coact with curved levers 40 pivoted to shafts 39 carried in the frame 14, the shafts carrying other curved levers 36 which coact with the sliding collars 31. When the rod 42 is drawn forward by means of the tapped head and handle 45, the collars 31 are depressed so that the springs 33 can no longer exert an upward thrust on the collars 25. The force of the springs 26 consequently acts directly on the bearing block 9 through the shoulder 24 on the rod 16. Toggle links 48, 50, jointed at 49, are pivoted at their free ends to a lug 29 on the collar 27 and at 51 to a lever 63 respectively. This lever is pivoted at 53 to a lug 30 on the collar 25, and a cranked arm 54, Fig. 6, pivoted to the frame 14, is formed integrally with the lever which moves over a scale provided on a plate 58, but not shown, to indicate the condition of the padding. The slotted end 60 of a T-shaped sliding bar 56 coacts with the pivot 49 of the toggle links, the free end 61 of the bar moving over a scale 62 to indicate the pressure applied by the spring 26.

[Class 100 (iv)] [Also in Group XIX] Hammer-impression arrangements ; web feeding and guiding arrangements.-The printing- mechanism of a cash register or similar accounting-machine comprises a single printing hammer having a number of platens each co-operating with one of a number of record strips, and means for moving a platen and its associated record strip simultaneously to operative position relative to a single set of type carriers. The invention is particularly applicable to machines of the kind described in Specification 8119/15, [Class 106 (i)], and consists in the provision of two record strips 32, 33, Fig. 1, adapted to be impressed each by one. of a pair of platens 37, 57 mounted on a hammer 92 that is rockable to bring the desired platen into printing position beneath a set of typewheels 30. Each record strip passes from a supply roll 34, over a stationary roller 35, round a guide roller 36 rigid with the associated platen, and over a fixed guide 38 to a storage roll 39. The left-hand strip is first impressed by an upward movement of the hammer, after which the hammer is rocked counterclockwise and again raised to impress the right-hand strip. Finally, the strips are linespaced by interconnected pawls 76, 91 cooperating with ratchet wheels on the storage rolls. These operations are all effected in the desired sequence by cams on. a shaft 85. To take up the slack in the strips as the hammer rocks and to permit the strips to be fed, each supply roll 34, Figs. 1 and 4, is connected by a stud 44 and spiral spring 45 to a disc 46, that is held by a spring 49 in frictional engagement with a collar 48 fast on a roll-supporting stud 41.
