Title: Improvements in or relating to the liquid treatment of knitted fabrics
IPC: D06B3/10
Filed: 1940-03-12
Abstract: 539,519. Treating textiles with liquids ; dyeing &c. processes and apparatus ; artificial silk. BRITISH CELANESE, Ltd. March 12, 1940, No. 4609. Convention date, March 14, 1939. [Classes 2 (ii), 15 (i) and 15 (ii)] A knitted fabric is treated with an aqueous liquid while in open width and under longitudinal tension while being free to shrink in width and it is subsequently subjected to a liquid treatment such as a scouring, saponifying, de-lustring or dyeing treatment while on a winch or otherwise in folded form. The preliminary treatment removes the tendency of the material to become permanently creased during the subsequent treatment in folded form. The process is particularly applicable to the treatment of cellulose acetate or other cellulose ester or ether fabrics particularly warp-knitted fabrics. The preliminary treatment liquid may contain soap or other wetting agent and it may be used at a raised temperature. After the preliminary treatment the fabric may be dried wholly or partially and then sewn into tubular form preparatory to the treatment in rope form on the winch. As shown, the knitted fabric 1 is drawn from a batch 2 in open width over opening or spreader bars 5, 6, and into tank 7 containing warm water. The fabric passes -round rolls 8-11, and out of the bath. It passes over a spreader bar 12 and a suction extractor 13, and is wound on a shell 14 which is positively rotated. Specification 338,190, [Class 15 (ii)], is referred to.

Title: Animated toy
IPC: A63H11/18
Filed: 1969-01-29
Abstract: 1,254,895. Ballerina doll. MATTEL Inc. 29 Jan., 1969 [11 Sept., 1968], No. 4840/69. Heading A6S. An animated figure toy comprises a body including a torso and appendages attached thereto, and a spot holding mechanism (which enables an appendage to remain stationary during at least part of a complete rotation of the torso and thereafter rapidly to rotate so as to "catch-up" with the torso) which is supported by the said body and is described with reference to "head-spotting". A head support block (150) defines a cavity (152) and is mounted on a shaft (156) which also carries a gear (157), and a cam (155), and at its upper end carries an element 161 having a stop 162. A torsion spring (154) is mounted in the cavity and fixed between the block (150) and the cam (155). Additional components are the cam follower (170) and arm (163) which is biased by spring (165) toward the stop, follower (170) and arm (163) being mounted on the same rod (168). Cam (155) is fixedly attached to the torso (122) and thus when the torso is operating to perform a pirouette motion the cam is also caused to rotate. The support block rotates with the torso only until extension (162) of element (161) engages the arm 163 when the position of the head becomes fixed, the motion of the torso being free to continue by virtue of the spring (154). The head remains fixed until cam follower (170) is displaced by the cam, when the displacement is transmitted to arm 163 via rod 168 which frees the head to rotate in the direction of motion of the torso. Due to the biasing action of the spring 165 the arm is immediately returned to a position in which it prevents the support block, and hence the head, from rotating again until the torso has rotated through a further 360‹ and head spotting is thus achieved. The means by which the body is caused to rotate is disclosed and claimed in co-pending Application No. 33071/70.

Abstract: 229,705. Telefunken Ges. f³r Drahtlose Telegraphie. Feb. 23, 1924, [Convention date]. Frequency, changing. - Alternating- current frequency reducing means comprises a transformer T the primary circuit A<5> of which is tuned to the frequency of the generator G, whilst the secondary circuit A<1> is tuned to the lower frequency required, this frequency being generated by utilizing small low frequency components of the supply current to produce self-excitation. For this purpose, a capacity Cp is provided in the secondary circuit and the low frequency power is consumed in a resistance R connected either in series or parallel with the capacity Cp, or inductively coupled to the inductance of the tuning element A<1>. As an alternative to the resistance R, a synchronous motor may be employed for consuming low frequency power, and, by over-excitation, the motor may be caused to take a leading current and thus replace, either partially or entirely, the capacity Cp. Upper harmonics of the low frequency current may be developed in a circuit A<7> connected as shown in Fig. 4 and tuned to the required frequency. When the output circuit consists of an antenna, the circuits are arranged as shown in Fig. 5. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the provision of a magnetizing current of low frequency for generating oscillations in the circuit A'.

Abstract: 684,137. Thermal switches. PIERCE FOUNDATION, J. B. March 5, 1951 [March 7, 1950], No. 5276/51. Class 38 (v) In a thermal switch having a bimetallic dished disc 30 fixed at its centre to a post 27, its periphery is engaged and biased by a dished spring disc 34 which serves to maintain good contact between the discs during the initial 'creepage' of the bimetallic disc just prior to its snapping over. The two discs may be connected to terminals of a circuit so that current passes through them, heating the disc 30 which thus snaps into the open position at a given overload. Adjustment of the spring pressure of the disc 34 may be made by rotating a knob 36 and the disc 34 is loosely mounted so that it may be rotated about its axis should sparking tend to occur always at the same points. In modifications, a second spring disc may be arranged on the other side of the bimetallic disc thus producing a two-way switch, Fig. 7 (not shown); the spring disc may overlap the bimetallic disc, Fig. 3 (not shown); the spring disc may be a bimetallic disc and produce ambient temperature compensation, Fig. 4 (not shown); the discs instead of being themselves switch contacts may actuate contacts, Figs. 8, 9 (not shown).
