Title: Improvements in domestic washing machines
IPC: D06F45/12
Filed: 1947-03-13
Abstract: 609,199. Wringers. ROBINSON & CO. (BOLTON), Ltd., B., and CHARLSON, E. March 13, 1947, No. 8105/46. [Class 138(ii)] Relates to a combined domestic washing- machine and wringer 11 in which the wringer is pivotally mounted by brackets 3 on the rear of the washing-machine and is capable of being swung into a horizontal position in which it is housed beneath a table top 14. According to the invention a vertical, or substantially vertical, backboard 5 is supported in sockets 4 in the brackets 3 for preventing the escape of water from the rear of the machine, when the latter is in use, and providing a support for .the rear of the table top when the wringer is folded to horizontal position, the table top being then maintained in position by front legs 15 resting on the rim of the machine. Legs provided on the wringer are adapted to be received in sockets 9 in supports 7, which are pivoted on pins 8 on the brackets 3. In the operative position of the wringer, the lower end of each socket engages a vertical face on a lug 6, Fig. 3, on the bracket 3 and is maintained in this position by a screwed clamp 13 which passes through the bracket and engages a depression 12 in one face of the socket; when the wringer is swung down to a horizontal position, the socket 9 engages a horizontal edge of the adjacent lug 6. When the table top 14 is mounted above the wringer, a channel-shaped guide 17 on the rear edge of the table top engages the upper edge of the backboard 5. The washing-machine is square or rectangular in plan and is fitted with the usual agitator 1 passing through the lid 2 of the machine.

Title: Improvements in fastenings for bags or the like
IPC: E05B65/48
Filed: 1923-03-22
Abstract: 216,973. Timings, S. March 22, 1923. Hasp locks and fastenings; hook fastenings.- A fastening, for bags &c. comprises a hasp member 1 on one part adapted to be passed through a peripheral slot 12 in a cupped retaining member 6 to engage over a ledge 19 in one of the upturned flanges 10 of an attachment plate 7 secured to the other part of the bag, the hasp being finally secured by rotation of the member 6 which is. secured to the plate 7 by a rivet 14 and has its base spaced above the plate 7 by a distance-piece 15. The retaining member instead of being slotted as shown may be formed as a quadrant. The member 6, which may be provided with one or more integrally formed handles 13, is indented at 17 to form projections adapted to co-operate with a projection 18 on one of the flanges 10 to limit the movement of the member 6. The hasp 1 may be pivotally attached to a plate 3, Fig. 1, by passing its end through a slot 4 and then bending the end over. In a modified construction the member 1 is rigidly secured to the bag and is bent upwardly and then downwardly at its engaging end, the flange of the member 6 engaging on rotation at the back of the upwardlybent portion. In the modified construction, Figs. 8 and 9 a key-operated locking bolt 36 is mounted between the attachment plate 27 and a, second plate 35, the portion 43 of the bolt being adapted to be moved into the path of a projection 41 provided on a downwardly-extending flange of the retaining member 25 and moving in an arcuate slot in the plate 27. The member 25 is prevented from being moved out of its locked position by excessive force by a projection 44 pressed up out of the plate 35 and adapted to contact with the underside of the portion 43 of the bolt when in its locking position to prevent the latter being forced downwardly.

Title: Cutting systems for producing grooved sound tracks
IPC: H03F1/36
Filed: 1957-03-13
Abstract: 841,294. Binaural systems. TELDEC TELEFUNKEN-DECCA, SCHALLPLATTEN G.m.b.H. March 13, 1957 [March 20, 1956; Nov. 26, 1956], No. 8293/57. Class 40 (4). In the recording of a gramophone record, preferably with two signals on a single track, the cutting stylus is actuated in two mutually perpendicular directions by two transducers. One or both of the transducers receive negative feed-back and one or both receive signals to be recorded. In a system for recording a single signal on a laterally cut record, an electromechanical transducer W1, Fig. 1, drives the stylus laterally. A mechanico-electrical transducer R1 may register the movements of the stylus and apply negative feed-back to the amplifier V1. Unwanted vertical movement which is liable to produce distortion is largely eliminated by a mechanicoelectrical transducer R2, responsive to vertical movements, applying negative feed - back through an amplifier V2 to a second electromechanical transducer W2. Similarly undesired movement of the stylus along the groove may be eliminated by R3, V3 and W3. In Fig. 2, two signals S1, S2 are recorded in a single groove by two transducers W1, W2 both subjected to negative feed-back. The two signals may be binaural and the feed-back reduces both resonance and cross-talk. Practical embodiment, Fig. 3. The magnetic circuit comprises a magnet 4 with polepieces 5, 6, 7 defining upper and lower air gaps. Annular closed copper bodies 8, 9 form shortcircuit windings which contribute to electrical decoupling. A coil carrier 3 is secured to a shaft 10 pivoted flexibly at 18 so that the stylus is movable in a plane perpendicular to the groove tangent. A first actuating-coil 11 consists of continuous turns and its energization by a signal produces a hill-and-dale recording. A pair of actuating coils 12, 13 each consist of a number of half-turns, arranged as seen in Fig. 4, the upper half-turns being clear of the magnetic gap. When the coils 12, 13 are connected in series, as shown, and energized by a signal current, then the coil carrier pivots at 10 to produce a lateral recording. A continuous coil 25 and two half-turn coils 26, 27 generate feedback voltage in accordance with the movements of the coil carrier. The arrangement of these coils in relation to hill-and-dale and lateral movements is shown in Fig. 5. Modifications. The coil carrier may be supported by tubular springs 29, 30 or 32, 33, Figs. 6-8. By making the resonant frequency in the direction of the groove tangent equal to the resonant frequencies in the lateral and hill-anddale directions resonance and cross-talk are very much reduced. The coil carrier may alternatively be supported by three springs 34, 35, 36, Fig. 9.

Title: Emergency supply circuit
IPC: H02J9/06
Filed: 1973-02-20
Abstract: 1401552 Emergency lighting circuits; standby supply circuits SAFT-SOC DES ACCUMULATEURS FIXES ET DE TRACTION 20 Feb 1973 [23 Feb 1972] 8348/73 Heading H2H An emergency supply circuit comprises a main power source 2, an auxiliary power source 1 for providing an adjustable reference voltage, a comparator circuit 7 for comparing a voltage derived from the main power source with the reference voltage and a switching device T 4  responsive to the output of the comparator circuit to enable the auxiliary power source to supply a load 12 when the voltage derived from the main power source falls below a threshold voltage set by the reference voltage. The voltage across a capacitor C1 is proportional to the main source voltage and is compared with the reference voltage provided by the tapping point 5 of a battery 1. When the mains voltage is normal, a transistor T1 is conductive and the conduction of a transistor T2 maintains a transistor T3 and consequently a transistor T4 non-conductive. Terminals A, C are therefore not connected and the fluorescent lamp load 12 is not illuminated. In the event of a decrease of the mains voltage below the threshold voltage, the change in state of the transistors T1-T4 enables the connection of the terminals A, C so that the battery 1 supplies power to illuminate the lamp 12. In a modification, the terminals A, C are permanently connected and the mains voltage energizes the lamp but on failure of the mains voltage, the battery connection to the terminal B is established via a transistor to enable the battery to energize the lamp.

Title: A process for the thermal rearrangement of salts of cyclic carboxylic acids
IPC: C07C51/41
Filed: 1957-03-18
Abstract: Compounds of the type Alk2(CdX2Y2), where Alk is an alkali metal atom, X is a halogen ion, especially fluorine, and Y2 is two halogen ions or a carbonate ion, which may be complex salts, double salts or mixed crystals, are prepared by mixing aqueous solutions of the appropriate alkali metal and cadmium salts and recovering the precipitate of the cadmium complex.  The examples describe the preparation of K2CdCl2F2, K2CdF4 and K2CdF2CO3.  Compounds of the type Alk(CdX3) may be similarly prepared.  The cadmium salts may be used to catalyze the thermal rearrangement of alkali metal salts of cyclic carboxylic acids (see Group IV (b)). Specifications 793,921, 809,755, 810,552 and 818,268, [all in Group IV (b)], are referred to.ALSO:Alkali metal salts of carboxylic acids where the carboxyl groups are directly attached to an aromatic ring system or a heterocyclic ring system of aromatic character, are prepared by heating an alkali metal salt of an aromatic or heterocyclic carboxylic acid, other than those to be prepared, in the presence of a catalyst comprising a compound of the general formula Alk2(CdX2Y2) or Alk(CdX3), where Alk repre sents an alkali metal cation, X a halogen ion and Y2 two halogen ions or a carbonate ion.  The preferred catalysts are those containing potassium and fluorine.  The salts which may be treated are those in which there is one or more carboxyl groups attached to a ring system such as benzene, naphthalene, anthracene, phenanthrene, diphenyl, furan, thiophene pyrrole, a -pyran, a -thiopyran, pyridine, pyrazine, quinoline, isoquinoline, indole, benzotriazole or benzimidazole.  The salts to be heated may be formed in situ by reacting an alkali metal carbonate with the acid or its anhydride, chloride, amide or imide.  The reaction mixture preferably contains 1-10% cadmium and is generally heated at 350-550 DEG  C. under the known conditions to obtain rearrangement, decarboxylation and disproportionation of such aromatic and heterocyclic acids.  The reaction product may be worked up by the addition of a mineral acid or in the case of alkali metal terephthalates, by the processes described in Specifications 793,921, 809,755 and 810,552.  The examples describe the preparation of terephthalic acid from potassium phthalate and potassium benzoate, and pyrazine-2,5-dicarboxylic acid from the 2,3-isomer in the presence of K2CdCl2F2, K2CdF4 and K2CdF2CO3.  Specification 818,268 also is referred to.
