Title: Improvements in or relating to mannequins and other mechanical display figures
Inventor: MAYCOC PHILIP
IPC: G09F19/02
Filed: 1966-09-27
Abstract: 1,202,195. Mechanical display figure. P. MAYCOCK. 26 Sept., 1967 [27 Sept., 1966], No. 42973/66. Heading G5C. A mechanical display figure has a trunk and limbs whose movements simulate those of a human being and which execute simultaneous rotary oscillatory movements about two mutually perpendicular axes 29 and 38. The driving means includes a flexible connector F, and means for adjusting the extent of swing of the arms. Arm drive means.-As described, each arm 30 of the figure is rotatable integrally with a sprocket wheel 37 caused to make reciprocating rotary movements about an axis 38 on a shaft 29. Wheel 37 is chain-driven (F) by a sprocket 39 non-rotatably secured to a sleeve 41, the sleeve being made to effect to-and-fro movements along the axis of shaft 29 by means of one of two bellcrank arms 21. Shaft 29 is rotatable about its own longitudinal axis, being driven by a chain 26 and sprocket 28; one end of chain 26 is connected to a crank arm 24, the other end to a tension spring 31, Fig. 2. Head drive means.-The figure's head is secured to a plate 46 rotatable about a horizontal axis 45, Fig. 2. A follower 51 on a lever 49 engages a cam 53 causing vertical movements of a connecting rod 48: the head is thus made to nod. Prime movers.-An. electric motor 12 chaindrives a gear-box 16 whose outputs are crank wheels 17, 23 for the arms and cam 53 for the head. Crnak wheels 17, 23 have their respective crank arms 20, 24 mounted thereon by adjustable dovetail slides 18, 25 in corresponding dovetail grooves in the faces of wheels 17, 23. By adjusting the positon of these slides the degree of swing of the arms 30 may be determined. The motor 12 may be driven by clockwork or fluid pressure; and instead of the crank mechanisms, the figure may be driven by fluid-pressure activated pistons.

Title: Improvements in or relating to the dyeing of textiles
IPC: C09B57/00
Filed: 1960-12-15
Abstract: Textiles consisting of filaments or fibres of a synthetic polymer, e.g., a polyamide, a polyester, polypropylene or polyacryonitrile, are dyed by applying a solution, preferably a benzene solution, of a compound produced by reacting tetracyanoethylene with pyrrole in the presence of powdered sulphur, and then treating with superheated steam.  The compound is preferably prepared in benzene and the reaction mixture so obtained used as the dyebath.  Treatment with superheated steam converts the dark olive colouration obtained to an intensive black.  Specification 807,744 is referred to.

Abstract: 1,038,387. Two-part couplings associated with switches. CARR FASTENER CO. Ltd. Sept. 4, 1964 [Nov. 4, 1963], No. 43490/63. Heading H2E. An electrical socket comprises an insulating body 1 with an axial bore 2 closed at one end by a plate 14, and two contacts 5 and 8 positioned in the body with tailpieces 6 and 9 extending through openings in the endplate, one of the contacts 8 including a resilient arm 10a provided with a portion 12 extending transversely of the bore into engagement with the other contact 5, a part of the arm being arranged so as to be deflected by an inserted plug away from the contact 5. The contacts are retained in the body by shoulders on the contacts abutting against part of the plate 14 which is itself retained in position by lugs 15 which are softened and expanded by heat and pressure to cause them to overlie portions of the plate. The body is held to an attaching plate 16 by a metallic retaining member including sleeve 18 and arms 19 which are bent over shouldered portions of the body. The sleeve 18 forms the outer electrical contact for engaging a mating plug and is formed with an integral earthing tag.

Abstract: 1,088,850. Coin freed apparatus. CLEVEDON ELECTRONICS Ltd. Jan. 27, 1966 [Oct. 27, 1964], No. 43768/64. Heading G4V. Coin-freed apparatus comprises a semiconductor binary counter, and a number of coin-operated pulse generators connected to the binary stages, so that insertion of a coin of value greater than the minimum applies a pulse representing a value higher than the minimum directly to a stage of the counter other than the lowest stage. In the Figure, insertion of a coin closes the corresponding one of microswitches I, to set the corresponding one of bi-stable storage circuits 2. The first four counter stages 3 count pence, the lowest two having a feedback path so as to count up to threepence only, the next stages representing threepence and sixpence. The remaining five stages count shillings, a feedback path giving twenty stable states. Pulses from a generator 4 reset the operated circuits 2 sequentially, so that pulses are passed to the corresponding counter stages 3, the 2/6 switch 1 setting two circuits 2 passing pulses to the sixpence stage and two shilling stage. The timing is such that carry pulses between the stages 3 and input pulses from the circuits 2 cannot coincide. A logic unit 5 reads and displays the total credit. Means are provided to lock the counter to prevent it going over its complement. A value is subtracted by addition of its complement.

Title: Wave-energy imaging technique
IPC: G01N29/06
Filed: 1974-10-10
Abstract: 1481090 Wave-energy imaging system RCA CORPORATION 10 Oct 1974 [15 Oct 1973] 43925/74 Heading G1G [Also in Divisions G2 and H4] An object is imaged by illuminating it with coherent wave energy, electromagnetic or acoustic, to provide object-modified energy which is incident on an array of transducers spaced around the circumference of a receiving aperture, coherently detecting each transducer output signal against a common reference signal to obtain for any one transducer two signals corresponding respectively to the real and imaginary components of a complex number defining the relative amplitude and phase of the object modified energy incident on that transducer, and processing all the coherent detection signals to derive a signal representing values of the image amplitude at image points corresponding respectively to points distributed over the object. Ultrasonic embodiment, Fig. 2:-For medical diagnostic imaging of body organs, ultrasonic waves from transducer 202 are coupled to the skin via water and a diaphragm 206. The circular array 214 of transducers receives reflected energy. The relative phase and amplitude of the array signals are determined by applying the signals to coherent detectors which also receive a reference signal from oscillator 200. The phase and amplitude data are then fed to an analogue and/or digital processor which transforms them to stored image amplitude data, some details given. The transformed data are displayed on a CRT. To reduce "speckle" in the displayed image, image data are averaged over a series of exposures of the object to the wave energy, acoustic diffuser, phase-shifter, 208 being re-positioned between exposures. Seismic embodiment, Fig. 3:-Underground structure 300 is imaged by use of circular geophone array 302 and randomly-placed seismic sources 308. Each source is an explosive one fired repetitively at a rate which defines the coherent frequency of the seismic energy. The firing rate control device 306 also provides a reference signal at the coherent frequency. The recorded geophone signals are processed as above. Each exposure corresponds to actuation of a respective one of the source 308, whose random placement results in image speckle reduction.

Abstract: 1,243,015. Multi-layer elastomeric spring units. K. MEYER. 17 Sept., 1968, No. 44147/68. Heading F2S. A resilient support for buildings or roads consists of resilient layers 1, 2, 3 alternating with rigid layers 4, 5, 6, 7. Some of'the rigid layers are plates with protrusions or indentations 8 to grip the adjacent resilient layer or layers; one of the rigid layers 4, itself consists of several layers of foil, e.g. plastics foil. A disadvantage of conventional multilayer resilient sandwiches is that transverse strains are set up in the layers when the sandwich is compressed, and these unpredictable strains prevent accurate calculation of the compressive loading characteristics of the sandwich; 'the present construction is designed to overcome this disadvantage.
