Filed: 1964-08-25
Abstract: 1,105,320. Centrifugal fans. SMITHS INDUSTRIES Ltd. March 30, 1965 [Aug. 25, 1964], No.34831/64. Heading F1C. [Also in Division F4] In a centrifugal fan for a heating and/or ventilating apparatus for a vehicle, comprising an inlet duct adapted to be positioned so that forward motion of the vehicle causes air to be forced into the inlet of the volute casing of the fan, each fan blade has its outermost portion directed in a radial or near radial direction, the remaining portion being generally inclined at a substantial angle to the outermost portion, and the innermost portion leading the outermost portion in the direction of rotation. With this arrangement a change in the static pressure against which the fan works from a positive value when the vehicle is stationary to a negative value at a high forward speed of the vehicle does not change significantly the power required to drive the fan. The front shroud of the fan impeller is of frusto-conical form so that the area of the flow path through the impeller is constant over the whole radial length of the blades. The driving motor is of either permanent magnet or shunt-wound type.

Title: Improvements in band resistances for continuously regulating heavy currents
IPC: H01C1/14
Filed: 1935-12-16
Abstract: 467,574. Variable resistances. AKT.- GES. BROWN, BOVERI, & CIE. Dec. 16, 1935, No. 34911. Convention date, Dec. 19, 1934. [Class 37] A heavy current variable resistance comprises a strip or band of resistance material wound into a spiral a and supported on bolts b secured to inner and outer rings d1, d2 with a fixed terminal contact c and two or more roller or friction contacts such as e, Fig. 2, which are rotatable with and axially slidable on a radial rod pivoted at the centre of the spiral and are arranged one behind the other in the direction of motion. The band is insulated from the bolts b by insulating spacers i and is strengthened where the bolts pass through it by means of annular discs threaded on to the bolts on either side of the band. Additional movable contacts such as e may be provided on the other side of the strip, Fig. 2, the rollers on each side being pressed together on to the band by a spring o connected between the radial rods 9 which are pivotally mounted on a rotary shaft n. Alternatively two separate spiral resistances may be mounted in the same frame with the movable contacts on the same rotatable radial bar g so that larger variations may be obtained with small angular movement of the bar g. The rollers may be connected together by a carriage from which the leading out connection may be taken. The roller farthest from the input fixed terminal is connected to the adjacent roller through a resistance. When two bands are used, Fig. 5, the rollers nearest the fixed terminal are mounted on an axle f<1> of resistance material and are connected to the conducting axle f<2> of the second pair of rollers by a bridge on which is mounted an idle pulley engaging the radial control rod g. Alternatively the pulleys el, e3 or e2, e4 of each pair may be of material having different conductivity compensating resistances may be dispensed with where two band resistances are used by arranging each of the rollers in a pair at the same peripheral distance from each other as in the other pair, and by cross connecting the rollers on one band with those on the other. A number of such resistances may be mounted coaxially and controlled from a common shaft with common forcecooling means in the form of a motor driven fan. The control shaft, which may also form the lead-in to the brushes, passes through the coaxial motor and fan shaft to a drive pulley which may be operated by bend or by a motor. Alternatively the brushes may be fixed and the resistances rotated in which case current to the " fixed " contact is supplied through a slip ring. The contact edges of the resistance strip may be turned over, beaded or otherwise thickened to increase the contact and current carrying area. The fan motor may be connected in circuit with the resistances so that its speed is dependent on the current carried by them. Specification 248,469, [Class 37], is referred to.

The objective, which is corrected for spherical and chromatic aberrations, coma, astigmatism, field curvature and distortion has four members LA, LB, LC, LD in which (a) LA and LD are convergent and stationary, (b) Lc and LD are divergent and movable, (c) the equivalent focal lengths fB and fc respectively of members LB and Lc lie numerically respectively between 4 and 8 and 5 and 10 times the minimum value of the ratio of the equivalent focal length of the objective to the f - number thereof e.g. fB is 5À88 and fc is 7À27 times such minimum value, (d) LB consists of a divergent simple meniscus component with its surfaces R8, R9 convex to the front followed by a divergent compound component and performing in the range of variation a total axial movement lying numerically between 1À5fB and 2À5fB e.g. 1À994fB, (e) Lc consists of a doublet component having a front surface R14 concave to the front with a radius of curvature lying numerically between 0À5 fc and 1À0 fc e.g. 0À72 fc and moves a total distance between 0À25 fc and 0À5 fc, e.g. 0À305 fc and (f) the minimum separation between LB and Lc occurs when the equivalent focal length of the objective is greater than half its maximum value in the range of variation e. g. is 0À745 times such value. The compound component of LB consists of a triplet component having a convergent element between two divergent elements. The member LA is moved for focusing at different object distances. The member LD may take various forms, Figs. 2-4 (not shown), in some of which there is an aspheric surface such as R23, and an achromatic doublet component may be provided interchangeably behind the member LD to increase the values of equivalent focal length of the objective throughout the range of variation e. g. without the additional doublet the range may be from a minimum Fo to 10Fo, with a particular added doublet Fig. 5 (not shown) the range is 1À5 Fo to 15 Fo and in another example, Fig. 6 (not shown) it is 2 Fo to 20 Fo. Optical data are given for four examples of objective and two examples of supplementary achromatic doublets.

Filed: 1966-05-12
Abstract: 1,145,745. Transistor delayed switching circuits. E. W. BLISS CO. 12 May. 1966 [12 May, 1965], No. 35126/68. Divided out of 1,145,744. Heading H3T. In a timing circuit TM1, a capacitor 22, Fig. 2, is charged upon receipt of an input signal, then partially discharged by means such as unijunction transistor 18 when the charge reaches a predetermined level and finally more completely discharged under control of a bistable multivibrator MM1 actuated by means 18. As described, capacitor 22 charges through resistances 26 and 24 when a normally conducting transistor 34 is cut off by an input pulse; when the voltage across the capacitor is sufficient the unijunction transistor 18 conducts and discharges the capacitor through resistance 30 thereby producing an output pulse across this resistance. In response to this output pulse an external bi-stable multivibrator MM1, Fig. 1, restores transistor 34 to conduction so that the capacitor 22 can complete its discharge through diode 32 and the transistor. This discharge circuit ensures that all the timed periods are equal; without it the first period would be longer than subsequent ones (Fig. 3, not shown) since the capacitor 22 cannot discharge completely through the unijunction transistor 18. Traffic control system.-Each of four signal lamps has associated with it a bi-stable multivibrator MM, Fig. 1, and a timing circuit TM. When the first bi-stable circuit MM1 is set it illuminates the corresponding lamp MSG and starts its timing circuit TM1. The output of the timing circuit sets the bi-stable circuit MM2 of the next phase; this re-sets the preceding bi-stable circuit MM1, illuminates its signal lamp MSC, and starts its timing circuit TM2.

Title: Improvements relating to pumps
IPC: F04D29/48
Filed: 1969-07-11
Abstract: 1,217,460. Centrifugal pumps. SIEMENS A.G. July 11, 1969 [July 13, 1968(2)], No .35177/69. Heading F1C. A pump comprises an impeller, an inlet and an outlet for liquid, a small port 1 which can communicate with the atmosphere and a ridge 7 adjacent the port, the pump being such that during forward rotation of the impeller a positive pressure will be created at the port whereas a negative pressure will be created during reverse rotation, whereby air will be drawn into the pump during reverse rotation to prevent the pumping of liquid. The port 1 is formed in the wall of the casing cover 4 of the pump, which is of centrifugal type, the location of the port being as described in Specification 1,213,448. When the impeller (not shown) rotates in the forward direction 3a, the flow is dammed against the ridge 7, so that water flows out through the port 1. When the rotation is in the reverse direction 3b, the flow near the wall is accelerated in passing over the ridge 7, producing a negative pressure whereby air is drawn through the port 1 into the pump to unprime it. As shown, the ridge 7 may be flush with the wall and flanked by recesses 5, 6. Alternatively, the recesses are omitted and the ridge then stands proud of the wall.

The links 30 and 31 are pivotally connected by a pin 34 which during relative movement between the rods is displaced perpendicularly to the line of stroke. The pin 34 is pivotally connected by a link 35 to a bell-crank lever 37 which engages an opening 41 in a pivotally mounted locking lever 40, biased to the locking position by a spring 42 and moved out of this position by an electromagnet 50. A stepping mechanism is provided having a ratchet wheel 60 comprising a gear rim 61 which is indexed by a pawl 62, corinected to a lever 64, and a gear rim 70 which co-operates with tongue 71 of the locking lever 40 to disengage it from the locking position. During the suction stroke of the pump the bellcrank lever 37 is locked by lever 40 and rod 15 actuates rod 20 through links 30, 31. The pawl 62 rotates the wheel 60 and at the end of the suction stroke a tooth on the rim 70 raises the lever 40 to unlock the bell-crank lever 37 and permit the spring 28 to cause a delivery stroke. The rim 70 is provided with a tooth gap which when positioned below tongue 71 prevents actuation of locking lever 40 and the pump mechanism remains locked until the electromagnet 50 is actuated. The pump outlet conduit 24 is connected to a nozzle.
