Title: Method of adhesively uniting materials, espeeially metals, and adhesives therefor
IPC: C07D301/28
Filed: 1947-07-14
Abstract: In a modification of the method of uniting materials adhesively described in the parent Specification, the adhesive mixture which is spreadable at ordinary temperature, is applied to the unheated surfaces at ordinary temperature and hardened between the surfaces by heat.  The mixture consists of an ethylene oxide derivative of a phenol which is either spreadable or solid, a solid hardening agent together if desired with a non-volatile liquid hardening agent, and, at least when a solid ethylene oxide-phenol derivative is employed a non-volatile solvent for the ethylene oxide derivative.  Solid ethylene oxide-phenol derivatives are employed by condensing up to 2 molecular proportions of epichlorhydrin or dichlorhydrin with one molecule of phenol in alkaline medium.  Spreadable products are obtained by employing a greater proportion of epichlorhydrin.  The phenols employed may be those mentioned in the parent Specification or condensation products of phenols with formaldehyde or acetaldehyde may be used.  The solid hardening agent may be any of those mentioned in the parent Specification.  Non-volatile liquid hardening agents which may be mixed therewith are triethylene tetramine, ethyl isocyanate, phenyl isocyanate, phenyl isothiocyanate and trithiocyanuric acid triethyl or triisoamyl ester.  Non-volatile solvents mentioned are resorcinol dimethyl ether, dibutyl phthalate, furfurol, and linseed oil, pinene, cymene, or cyclopentadiene together with another non-volatile liquid to obtain a mixture which is homogeneous and spreadable at ordinary temperature.  In examples 1-4 aluminium sheets are united with a spreadable resin prepared from dioxy-diphenyl propane and glycerin a -dichlorhydrin mixed in example 1 with (a) phthalic anhydride and (b) dicyandimide; in example 2 the resin is heated with resorcinol dimethyl ether and dicyandiamide and melamine are used as hardening agents.  In example 3 the resin is mixed with furfurol and phthalic anhydride is the hardening agent. In example 4 the resin is mixed with melamine and triethylene tetramine. Examples 5-15 are similar, employing a solid resin from dioxydiphenyl propane and glycerine-a -dichlorhydrin together with non-volatile liquids.  In example 16 a number of adhesive agents are described incorporating resins from different phenols. Example 17 describes the uniting of copper to copper, iron to iron, zinc to zinc and brass to brass.  Example 18 illustrates the effect of differing hardening times on the shear strength of the joint, and example 19 describes the uniting of glass to glass, glass to "Melopas" (Registered Trade Mark), and "Melopas" to "Melopas".

Title: Hammer drill
IPC: B25D11/10
Filed: 1963-05-10
Abstract: 961,654. Percussive drills. E. BILSTEIN, and E. BAUER, [trading as C. BAUER [Firm of]]. May 10, 1963 [May 14, 1962], No. 18661/63. Heading B4C. A hammer drill comprises an electric motor 10 driving a hollow shaft 4 in which a hammer member 5 is movably mounted, the hammer having a control pin 6 extending through a slot 12 in the shaft for rotatably coupling the hammer to the shaft and for co-operation with a stationary cam 14 to thereby effect reciprocable movement of the hammer. The motor is mounted on a housing member 3 within which a ring 14 having three cam lobes is secured by screws 19. In operation, when the shank of a drill bit is inserted into a chuck 9 and the motor started, the drill is rotated and, via the pin- and-cam device, the hammer continuously strikes the shank under the action of a spring 2. In the modification shown in Fig. 4, a ring 39 provided with teeth 38 is slidably mounted on the shaft 24 and connected to the hammer by pins 36 movable in slots 37. The teeth 38 co-operate with similar teeth 38<SP>1</SP> formed on a ring 391 which is provided with pins 41 passing through slots 42 in the housing 21, the pins engaging in a groove formed in a ring 43 mounted on the housing. By adjusting a screw-threaded ring 47, the ring 43, together with the toothed ring 39<SP>1</SP> is axially moved so that either the degree of impact may be varied or the coacting teeth disengaged entirely, thereby stopping the percussive action. In other modifications, the cam lobes or teeth need not be formed on a ring but can be separately secured on the housing itself.

Title: Improvements in electrical control systems
IPC: B60L15/20
Filed: 1925-07-22
Abstract: 237,897. Forges et Ateliers de Constructions Electriques de Jeumont. Aug. 2, 1924, [Convention date]. Master control systems; controllers, actuating. - In controllers of the separate contactor type, the contactors are actuated by successive movements of two camshafts; the first shaft. which requires small power, acting upon movable parts of the contactor mechanism so as to form temporary rigid abutments, through which force is transmitted from the second shaft to close the contactors. Plane or helicoidal cams are employed. The shafts may be turned by ratchet and pawl mechanism actuated by electromagnets or pneumatic devices, and may be arranged for automatic progression under current limit control. For braking or reversing, in which contactors are operated in a different order from the normal progression, endlong movement of the cam-shafts is effected by electromagnetic means. Means are provided for latching the contactors after closure and for releasing the latches to allow the return strokes. Figs. 1, 2, 3 and 4 shows one of the contactors and its operating mechanism. The preparatory movement of a cam 15 on a rotary shaft g takes effect through a lever 17 upon two pivoted abutments 24, 29 both mounted on the contactor arm 1 and sets them in the path of rollers 13, 14 mounted on a rocking shaft 10. Successive to- and-fro movements of the rocking roller member close the contactor by positive action through the abutment 24 and open the contactor by releasing a latch 25 through the abutment 29. The intermittent rotary movement of the shaft g is produced by a ratchet b<3>, a pawl b<2>, and an electromagnet b. The rocking movement of the shaft 10 is produced by a crank or the like from an electromagnet e. Controlling switches for the magnet b may be arranged either for automatic or non-automatic advance of the shaft g. The cam 15 is fitted with a pin 25<2> which releases a latch 25<1> and thereby opens the contactor when the shaft b is returned to zero. Several cams are disposed on the shaft so as to close corresponding contactors in order for motor starting purposes; the return of the shaft b opening all the contactors. In a modification, an additional electromagnet returns the cam-shaft. In a further modification, one intermittently excited magnet is arranged to perform the double function of advancing the shaft g and rocking the shaft 10, and a compressible spring link actuates a safety switch in case the contactors stick or become blocked. A line circuit-breaker subject to automatic release may be closed by a linkage from the rock shaft. Diagrams of automatic and non- automatic control schemes are given, embodying series-parallel and electric braking features of known character. Specification 230,856. [Class 38 (i), Electric couplings &c.], is referred to.
