Patent GB-442856-A (GB)
Abstract: 442,856. Calculating - apparatus. BURROUGHS ADDING MACHINE CO., 6071, 2nd Boulevard, Detroit, Michigan, U.S.A. May 16, 1934, No. 14795. Convention date, May 27, 1933. [Class 106 (i)] A machine is provided with a counting mechanism for registering the number of transactions such as the number of customers served by the operator using the machine. The counting mechanism is operated under the control of the printing mechanism, the counter operating mechanism being conditioned under the control of the manipulative control members that set the machine for single item transactions or for total taking in multiple item transactions. The invention is shown applied to a machine of the Burroughs portable type as described in Specification 265,122, [Class 106 (i)]. Such machines have banks of amount keys 10, Figs. 1 and 3, a bank of control keys T, ST, NA, SI, &c. for total-taking, sub-total-taking, non-adding, selection of registers 13, 14, &c. and the usual form of printing mechanism. In operation, the differential actuators 12 are moved to extents depending on the keys depressed and their latches 32 engage the ends of the impression hammers 17. During the continued movement of the main shaft 18 the latches 32 cock the hammers 17 until the latches are freed and the hammers under spring action are then fired. When the hammers are cocked a spring-controlled bail 54, Figs. 1 and 2, is swung forwardly so that a projection 53 thereon will engage a notch 52 in a pawl 49 if said pawl has been moved into its path. The setting of the pawl 49 into effective engaging position is under the control of a bail 63 shaped to co-operate with certain of the keys of the control bank. In the present instance the bail 63 has projections 66 adapted to co-operate with the single item transaction key S1 and the total key T. Depression of either key causes the bail to rock and through a linkage 68, 69 effects the rocking of the pawl 49 so as to raise its notched end 52 into the path of movement of the projection 53 on the bail 54. The pawl 49 is pivoted to a spring-controlled bail 43 pivotally mounted on the spindle of a counting mechanism 41 and carrying a set of actuating pawls 48. By this means, when the machine is operated, the printing mechanism through its action on the pawl 49 operates the counting mechanism. If, when the register is clear, the machine is operated as in totaltaking, this action is not effective to operate the counting mechanism, as the hammer for the clear sign is cut away so that it does not rock the bail 54 when it is cocked. When the machine is combined with a cash drawer, the control keys T, S1 will be provided with mechanism to govern the opening of the drawer.

Abstract: 1,207,178. Feeding record tapes. NEWELL INDUSTRIES Inc. 2 Oct., 1967 [7 Oct., 1966], No. 44678/67. Heading G5R. One track of a recorded tape 17 is played back as the tape is unwound from a supply roll 22, the tape drive is reversed when the imminent unwinding of a predetermined portion of the tape is detected, and a second track is played back as the tape is driven in the reverse direction. As shown, the tape transport is of the type described in Specification 1,144,647. Each carriage 16, 18 supporting a hub 13, 15 on which the tape 17 is wound carries an adjustable stop 66, 67 which at a predetermined point during recording closes a microswitch 68, 69 to activate a tone generator 74. This causes a control signal to be recorded on the tape and energizes a solenoid 47, which increases the compressive force between the tape rolls 22, 23 and the capstan 21 and closes contacts 58 to initiate the reversal of the drive motor 27 and the lateral shifting of the magnetic head 45 by an eccentric cam 86 secured to a commutator disc 87 which is stepped by a motor 88. This shifting of the head 45 to the next track is timed to occur substantially at the moment when the tape has come to rest before reversing. During playback, the energization of the solenoid 47 is brought about by the detection of the recorded control signal on the tape.

Abstract: 1402744 Flavouring carriers E E BECK 27 Sept 1972 44707/72 Heading A2B A carrier composition for essential oils comprises hydrolysed cereal solids, e.g. corn, having a dextrose equivalent (D.E.) of less than 20, and a sugar, e.g. sucrose, and is in the form of rod-like particles, and has an inert anti-caking agent mixed therewith. The composition is made by mixing and heating the sugar and hydrolysate to 122‹C in a tank 10 with an emulsifying agent, e.g. mono- and di-glycerides of Na sulphoacetate, mixing an essential oil and an antioxidant e.g. butylated hydroxyanisole (BHA) or butylated hydroxytoluene (BHT) in a second tank 13, and transferring both mixtures to an emulsification tank 12 and then by air pressure (60- 100 psig) to an extruder 15 having 1/64" orifices. The combined mix is extruded into a tank 16 containing isopropanol which solidifies the extrudate and is then agitated to break up the extruded rods to the desired size and to remove excess oils therefrom. The rods are then centrifuged, mixed with about 0.5% by wt. of anti-caking agent e.g. a silica powder (preferably pyrogenic silica), screened and dried at about 100‹F. Alternatively the anticaking agent may be added to the isopropanol before extrusion. The oil content carried by the composition is 0.1-10%, preferably 8-10%. Particle size is 20 mesh or finer. Oils which can be used are citrus, e.g. orange. anis, wintergreen or spearmint. Artificial sweeteners such as saccharin may be added. Instead of sucrose, dextrose or laevulose may be included.

Abstract: 1327248 Tracked gas cushion vehicles; railway systems BERTlN & CIE 2 Oct 1970 [2 Oct 1969] 46949/70 Headings B7K and B7L A trim stabilizing system in a gas cushion vehicle for running on a track, has a gas cushion 19 bounded by a skirt 18 attached to a bearing plate 8 which is so mounted on the vehicle for relative movement thereto that compensation occurs for variation in the distance between the vehicle and the surface over which it travels. When loading the vehicle, as represented by the weights 25, 26, is uneven; increase in load, e.g. on the right in Fig. 5, causes spreading of the skirt 18, reduced clearance between the skirt 18 and the surface, and increased pressure in the gas cushion which in turn causes gas to pass through apertures 21 and expand the chamber 9. A spring 17 limits the expansion of the chamber 9 so that it compensates exactly for compression of the cusion 19. In the embodiment of Fig. 5, gas is supplied through ports in a track 1, which are opened as the cushion passes over them. Because of the small size of the apertures 21 compared to the cushion size, small duration variations of pressure in the cushions 19 are not transmitted to the chambers 9 so that small irregularities in the track or obstacles thereon are largely absorbed, whereas long term pressure variations, such as those caused by cornering or uneven loading, are transmitted to cause compensation as previously described. Valves (21a), Fig. 4 (not shown), may be provided in each aperture, so that apertures are opened when desired, e.g. during loading. Fig. 9 shows a tracked gas cushion vehicle where gas is supplied by sources 6 mounted on the vehicle 7 to guide cushions 19<SP>1</SP> and support cushions 19 running on an inverted-T track 5, the arrows Y and X denoting excess unsymmetrical loading applied to the left hand guide cushion and right hand support cushion.

[Also in Division El] A ladder 21 is pivoted on the upper horizontal tubes 12 of a frame having groundengaging props 32 for stabilizing the ladder which are pivoted offset on vertical tubes 13 of the frame so that, when the ladder is swung down to a horizontal position and the props are folded against the frame for moving the ladder, the props obstruct movement of the ladder to operative position and thus prevent its use with the props in folded position. The pivots 29 of the ladder are offset oppositely to the platform 24 on top of the ladder so that the centre of gravity is in such a position as to swing the ladder down to its folded position and prevent its use unless the ladder is positively secured by clamps 46. In operative position the lower tubes 34 of the props each extend half way across the frame and engage a stop 43. One prop can be raised to avoid the stop and be folded the other way so that it does not obstruct the ladder, so that the ladder can be used against a wall. A stop prevents similar movement of the other prop.
