Title: Coin actuated operating mechanism for vending machines
Inventor: BOOKOUT FLOYD VEST
IPC: G07F13/06
Filed: 1958-04-30
Abstract: 854,630. Electromagnetic switches. VENDO CO. April 30, 1958, No. 13678/58. Class 38 (5). [Also in Groups VI and XVIII] A solenoid-operated rotary switch for controlling the operation of a vending machine for beverages composed of different selectable ingredients comprises three sets of stationary contacts 941, 942, 942<SP>1</SP> engaged by contacts such as 946, 947 rotatable by a solenoid 902 and ratchet drives 922 and, on a disc 940, two sets of similar stationary contacts engaged by contacts rotatable by a solenoid 903 and ratchet drive. A rod 911 or 914 coupled to each solenoid has a pin 927 engaging a crank 925 on the ratchet drives and the two rods are interconnected by an arm 915 rockable about a pivot 905 coupled to the rods through springs 917, 919. When one solenoid is energized, both springs are compressed by the rocking of the arm 915 and the pivot is adjusted so that; even if one solenoid is energized only slightly before the other, it will complete its stroke and the other solenoid will be prevented from moving its rod until the first solenoid has been de-energized. On movement of a rod towards the energized solenoid, a single-toothed driving ratchet 922 slips back over one tooth of a driven ratchet 929, which is held by a lug 932, and the drive is then in a cocked position ready to advance the driven ratchet one step on de-energization of the solenoid. Interrupting switches 950 and 960 are included in the circuit of each solenoid and have a swinging contact 957 spring-coupled to a toggle 951 operated by a cam plate reciprocated by a pin on the solenoid rod. The sets of stationary contacts 941 &c. are shown as a, b, c, &c. in Fig. 5-c, and the rotary contacts, according to the circuits they link up, have varying number of wipers, such as 509, 511 in Fig. 5-c. The contacts controlled by solenoid 903 (616 in Fig. 5-c) are first moved through one step by the energizing and de-energizing of the solenoid by a falling coin and circuits are then prepared for operation of solenoid 902 (516 in Fig. 5-c) on momentary depression of a customer-operated selection switch. As solenoid 902 makes an energized stroke, it opens its circuit at the interrupting switch 950 (517) and so de-energizes itself until the switch closes on the return stroke and recycles the solenoid. The rotary contact 509 therefore searches over a number of contacts a, b, c, &c. until it finds the one corresponding to the operated selection switch and the other ganged contacts operated by solenoid 902 (516) have then been rotated to positions setting up appropriate circuits corresponding to this selected switch. Completion of the operation of the vending machine operates the solenoids to restore the rotary contacts to an initial standby position. The switch 960 (617) serves an electrical interlock to prevent simultaneous operation of the two solenoids.

Title: Improvements in or relating to fire-retardant and potentially heat-insulating compositions
IPC: C08G12/00
Filed: 1945-06-01
Abstract: A fire-retardant composition, which may be applied to wood, metal, cellulosic wallboard, paper or cardboard, comprises urea, a source of formaldehyde and monoammonium phosphate, diammonium phosphate, phosphoric acid, ammonium sulphate, sulphamic acid, ammonium sulphamate, ammonium bromide, sodium tungstate, sodium borate or boric acid.  The urea and formaldehyde constitute 20-70 per cent by weight of the other ingredient.  The composition may also include an amylaceous substance, e.g. starch, dextrin, or carbohydrate, or a protein and a fungicide may also be included, such as sodium pentachlorphenol, b -naphthol, copper fluoride and other copper salts, boric acid, borax, zinc salts, fluorides, arsenates and arsenites.  A swelling agent, such as gum tragacanth, gum arabic and Irish moss, and, optionally, pigments, dyes and other colouring matter may be added.  The composition may be solid, liquid, or a paste, being suspended in water or a drying-oil.  Polymerization may be delayed by using paraformaldehyde and water, which may be mixed with the other ingredients at the time of use.  The molecular ratio of formaldehyde to urea may be between 1 and 2.5 moles. formaldehyde to 1 mole. urea, the preferred range being 1.5 to 1.7 moles. formaldehyde to 1 mole. urea.  In the examples: (1) paraformaldehyde, monoammonium phosphate, urea and starch are mixed, and optionally titanium-barium pigment, boric acid and tragacanth gum, with water to produce a paint.  The paraformaldehyde is kept separate before mixin; (2) monoammonium phosphate, urea, starch, tragacanth gum, pigment, water and 37 per cent aqueous formaldehyde are made up into a paint. In example 3, monoammonium phosphate, urea, water and paraformaldehyde are used.  The composition of example 4 may be applied to steel and comprises monoammonium phosphate, urea, starch, titanium barium pigment, boric acid, tragacanth gum, sodium dichromate and paraformaldehyde.  Alternatively steel may be washed with a solution to render it passive or coated with a primer coat, e.g. of red lead and drying oil.  Specification 334,408, [Class 140], is referred to.  The Specification as open to inspection under Sect. 91, includes the use of a preformed condensate of urea and formaldehyde and is not limited as regards the proportions of the ingredients.

Title: Loudspeakter cabinet
IPC: H04R1/28
Filed: 1971-05-07
Abstract: 1346083 Loud-speaker enclosures NECKERMANN VERSAND KGaA 7 May 1971 [8 May 1970] 13833/71 Headings H4J and H4X A loud-speaker cabinet has a front wall 2 with a sound aperture 4, a partition 6 spaced from the front wall 2 and having an aperture closed by a loud-speaker unit 1, and foam material disposed within the cabinet to define at least one damping wall 14 and at least one damping chamber within the cabinet. The partition 6 has two end walls acoustically sealed to the cabinet. Other end walls of the partition 6 are spaced from the cabinet to define parts 11 through which sound from the rear of the loud-speaker diaphragm passes into a gap 7 to mix with sound from the front of the loud-speaker diaphragm. At least two opposite cabinet walls are braced. As described, the bracing is performed by a T-shaped member 12 whose stem is secured between the cabinet rear wall 3 and the loudspeaker unit 1, which is thereby pressed against the partition 6. The cross arm of member 12 braces two vertical side walls of the cabinet. Two vertical foamed sheets 14 are glued to this cross-arm. The stem of the T supports two horizontal foamed sheets 14. Alternatively these two foamed sheets 14 are vertical (Fig. 4, not shown). All the sheets 14 terminate short of the cabinet walls. The partition 6 is spaced from the front wall 2 by spacers 5. The size of the gap 7 is adjustable by screws 9, the end regions of the partition 6 being deformable. The sound aperture 4 in the front wall 2 is preferably frustum shaped and diverges towards the partition 6. Relatively small cabinets (volume 3À6 to 15 litres) have a front wall of internal length equal to, at most, 3 diaphragm diameters and of internal width equal to, at most, two diaphragm diameters. The cabinets are narrow, and deep from front to rear. Intermediate cabinets (volume 15 to 26 litres) have the largest dimensions from front to rear and a ratio 3 : 4 is suitable for the width to length ratio of the front wall. Larger cabinets (26 to 50 litres) are smaller from front to rear than from side to side.

Title: Improvements in and relating to power-operated wrenches for screwing up nuts, bolts and the like
IPC: B25B23/145
Filed: 1938-05-10
Abstract: 497,912. Positive clutches. CHICAGO PNEUMATIC TOOL CO. May 10, 1938, No. 13934. Convention date, June 5, 1937. [Class 80 (ii)] [Also in Groups XXII and XXVI] A power-operated wrench for screwing-up or unscrewing nuts, bolts, &c. has a rotatable anvil connected to the tool and a rotatable hammer carrying pivoted dogs which are actuated by centrifugal force to engage claws on the anvil when the speed of rotation is high but are collapsed by spring action when the speed of rotation is low in order to deliver rotational hammer blows to the anvil in rapid succession. In a portable wrench, a casing 1 carries a bearing sleeve 3 for the tool shaft 4 and a rear plate 2 provided with a hand grip (not shown). The tool is driven by a compressed-air rotary engine whose cylinder 15 is formed integral with a hammer 16 having a radial slot 21 at the end in which the dogs 23 are pivoted at 24. A spring 27 on the stator extension 9 abuts on a washer 28 secured to the hammer and engages a sliding collar 29 connected by links 31 to the dogs. When the cylinder is stationary, the spring 27 maintains the dogs collapsed, as shown in Fig. 1, but on rotation of the cylinder centrifugal force causes the dogs to fly outwards against limiting pins 26, as shown in Fig. 2, and their engaging surfaces 25R enter between the claws 25 on the anvil 6 formed integral with the tool shaft 4. The screwing-up tool is thereby rotated at high speed whilst the nut &c. is being run up, but when the resistance to rotation increases suddenly the speed of the cylinder 15 falls and the dogs are collapsed by the spring 27 to disengage the drive. This relieves the torque on the engine and allows it to speed up, throwing out the dogs against the pins 26 so that they are in the fully-engaged position before they again meet the claws 25 to deliver a rotational blow to the anvil. These blows are repeated in rapid succession so long as air is supplied to the engine. Axial movement of the shaft 4 is prevented by a thrust ball 14 and a flange on the bush 3. In a modified construction, the dogs 52, Figs. 21 and 22, are pivoted at 51 in the hammer slot 49 and have projections 61 engaged directly by the spring-pressed collar 60 to urge them to the collapsed position shown in Fig. 21. When the dogs are thrown outwards by centrifugal force, as shown in Fig. 22, to engage the claws 54 of the anvil 53, their motion is limited by striking against a split ring 57 on the cylinder 15. The tool shaft 4 is made long so that its torsional resilience will prevent the dogs 23 from binding against the claws 25 under pressure and allow rapid disengagement of the clutch.
