IPC: A23G9/28
Filed: 1949-03-01
Abstract: 658,336. Filling containers. THORNTON, A. A. (Palmer, Inc., F. D.). March 1, 1949, No. 5574. [Classes 94(i) and 125(ii)] In an apparatus for filling containers with viscous liquid material. e.g. ice-cream, The material is supplied through a vertically reciprocating nozzle having valve arrangements therein which allow passage of the material only during the upward movement of the nozzle. The material comes from a container by way of pipe 36, Fig. 1, pressure relief device 35, 37, 39, and pipe 34 to the nozzle which is positioned at 33 and a carton c is fed to this position, and temporarily halted from between the endless conveyers 3, 4 by a pusher plate 7 reciprocated horizontally, under the control of a cam shaft, transversely to the conveyers, the filled carton F being removed between other conveyers 5, 6 on the next forward movement of the plate 7. The nozzle 31, Fig. 4, preferably of rectangular section, is reciprocated between guides 42 by a linkage 44 controlled by the cam shaft, and the lower end of the nozzle carries a transverse cylinder 51 having apertures 52, 53. Valve gates 70 are carried by rotatable plates 56, 57 forming the ends of the cylinder 51 and provided with slotted ears 58, 59 in which rollers 75 engage, the rollers being carried by levers 72, 73 pivoted at 74 on the nozzle and connected to opposite sides of a rock shaft 82. A roller 26, Fig. 5, on one of the arms 80 of the rock shaft engages a vertical guide 88 which is horizontally reciprocated by a linkage 92 controlled by the cam shaft and the arrangement is such that the valves 70 are opened when the nozzle is at the bottom of the carton as shown in Fig. 5 and remain open during the ascent of the nozzle whereupon they close and remain closed during the descent of the nozzle. The valves are maintained closed at the top of the stroke of the nozzle by the engagement of the roller 86 with a stationary guide 85 as shown in Fig. 4.

Patent GB-223128-A (GB)
Title: Improvements in apparatus for registering and recording the passage of vehicles containing predetermined minimum loads
IPC: G01G19/00
Filed: 1924-03-05
Abstract: 223,128. Heinz, P. March 5, 1924. Weigh-bridges. - Apparatus for counting and recording the passage of coal trucks &c. carrying not less than a predetermined minimum load comprises in combination a weigh-beam having one arm loaded, a ramp on or connected to the other arm of the weigh-beam, the latter arm having a rearward bend whereby the approach end of the ramp is placed in rear of the beam fulcrum, a registering or recording mechanism, and connecting means between the mechanism and the loaded beam arm whereby a rocking movement of the arm actuates the registering mechanism when a sufficiently-loaded vehicle passes over the ramp. The truck runs over and depresses the ramp-like end 1 of a bent lever A, A<1> controlled by powerful springs 7. Owing to the bend in the lever, the shock due to the entrance of the truck does not tilt the lever but tends to press it upon an abutment 36. Permanent records, apparatus for giving.-The movement of the bent lever due to the entrance of the truck is transmitted through a spring 11, weighted lever 13, strap 16 and rods 22, 21 to a ratchet disc 18 coupled by a rod 20 to a second disc 17. The discs carry electric contacts 33, 34. The load rotates the disc 18 in a counterclockwise direction and brings the contacts 33, 34 together to complete a circuit controlling the recording mechanism. Towards the end of the rotation, if the load is above a predetermined minimum, an abutment 31 pushes the upper end of a rocker 27 away from the ratchet teeth 50. When the truck passes off the lever the discs begin to return under gravity and a bent portion of the rocker slides over the inner surface of a boss 30 so as temporarily to prevent the engagement of the rocker with the ratchet teeth, thereby allowing the discs to resume their normal positions with the contacts 33, 34 separated. If the load is below the requisite minimum the smaller rotation of the disc 18 is insufficient to push away the rocker 27 and consequently the discs are not allowed to return and the current is maintained through the contacts 33, 34. Empty trucks do not bring the contacts 33, 34 into engagement. The current established by closure of the contacts 33, 34 energizes an electromagnet and produces a small movement of a style arranged to mark a record strip. The record strip is carried by a clockwork-driven drum which both rotates and moves axially. A portion of the record produced is shown in Fig. 5. Each time a full load passes over the lever the contacts 33, 34 are closed and immediately opened, thus producing a to and fro movement of the style and marking the record strip with a short dash 50. With a partial load, however, the contacts do not re-open until a full load has afterwards passed and consequently the style makes an inverted U-shaped mark 51 on the strip. The electromagnet also operates a counter each time the circuit is broken, thus counting the fully-loaded trucks.

Title: Improvements in or relating to raking implements
IPC: A01D78/00
Filed: 1957-02-20
Abstract: 859,235. Haymaking machinery. VAN DER LELY N.V., C. Feb. 20, 1957 [March 9, 1956], No. 5764/57. Class 6(3). The rake wheels of a raking device are mounted in echelon formation on a frame by means of two groups of supports, the supports of one group being detachable from the frame so that the device can be brought from one working position to another by detaching the supports of one group from the frame and re-mounting each of the removed supports at a location on a corresponding support of the other group. The frame of the device comprises parallel tubes 1 and 2 rigidly interconnected by bows 3 and 4, supported by adjustable caster wheels 20, 21 and 22, and connected to a traction vehicle by draw bar 5 pivotally connected at its forked, rearward end to the tube 1. The rake wheels 48-51 are mounted on supports 40-43 respectively so as to be each adjustable about a vertical axis 45, the supports each being received in a sleeve 38 which can pivot in a horizontal plane about a pin 37A mounted on one of four further sleeves 29-32 which are carried by the tube 1 and are rotatable about the axis of the said tube. Thus the supports 40-43 may be adjusted in three different ways : firstly by pivoting about the pins 37A, this movement being prevented when desired by pins 39 engaging apertured strips 36 attached to the sleeves 29-32, secondly, by displacing the sleeves 29-32 along the tube 1 and securing them in the required position by pins 33 engaging holes in the tube, and thirdly, by pivoting about the axis of the tube 1 in order to counteract uneveness in the ground or for transport purposes, in which case the rake wheels are lifted by mechanism described below. The supports 40 and 42 are removably held in then respective sleeves 38 by pins 54, and on withdrawing the pins, the said supports may be removed from the frame and mounted in sleeves 56 and 57 provided on the supports 41 and 43, again being held in place by the pins 54. By rotating the plane of rotation of each of the wheels 48 and 50 through 90 degrees about the corresponding axis 45, the device then operates as a swath turner. The supports 41 and 43 can be rotated in their sleeves and fixed in the desired position by pins 55 engaging holes in lugs attached to the sleeves and supports this providing a means of varying the pressure exerted on the ground by the wheels 48 and 50 in this second working position. The mechanism for lifting the rake wheels is as follows. Each of the supports 40-43 carries an apertured strip 58, one end of a spring 59 being engaged in one of the apertures and the other end being slidably mounted on a rod 60, the rod 60 being connected to a rotatable shaft 62 by means of two levers 61. The levers 61 extend beyond the shaft 62 and are joined by springs 65 to the tube 1. The shaft 62 carries an arm 66 connected by a chain 67 to one end of a rocker 69, the other end of which is connected to a lever 76, so that by moving the lever 76 the rod 60 and wheels 48-51 are raised simultaneously. Specifications 859,236 and 859,237 are referred to.

Title: Improvements in or relating to selector apparatus for automatic telephone systems
IPC: H04Q3/62
Filed: 1953-03-06
Abstract: 738,608. Automatic exchange systems. ADLER, A. E. March 4, 1954 [March 6, 1953], No. 6249/53. Class 40 (4). In an exchange system with normal dialling facilities for controlling selector mechanism 6, Fig. 1, some stations such as No. 1 have direct access to selected stations such as No. 2 through a 5-bank uniselector 8 individual to the calling station. When a called station tests busy, a privileged calling station automatically transmits a characteristic priority tone. The called party either hangs up and answers the call in the normal manner or superimposes his speech on the tone. A wanted line is marked on the test bank by means of a key or button at the station and the switch finds the marked line. The other four banks are connected to a speaking circuit 9, a P-wire and a wire d over which a drop indicator may be operated for priority calls. A station, Fig. 2, includes the usual transmitter T, receiver R and ringer BZ. To make a call, key K and one button PB are operated after lifting the receiver. Relay A energizes a driving magnet DM which steps the switch until test relay D pulls up. At the same time, relay B pulls up over winding II and is followed by relay E if the wanted line is marked free on the P-wire. Both relays hold to A. Ringing current from a source 33 is connected to the called line through winding B(I) and ringing tone on lead 36 is returned to the calling station through windings of relay A. On reply, the two windings of relay B are energized in opposition and the relay falls back, ringing stops and the speaking circuit is completed. Battery TB and windings A(I), A(II) form a transmission bridge for the two lines. Priority facilites. Relay F enables station 1 to call another station even when it is busy. On making a call to a busy line, relays A, B, D pull up as described but E does not respond. Relay F then pulls up and a priority tone on lead 34 is connected to relay winding A(III). The signal is passed from relay A to line through condensers Cl, C2. Speech can then be superimposed on the signal. Alternatively, if both the called party and the third party hang up, the call can be completed in the normal manner, the priority tone being cut off when E pulls up. A drop indicator may be operated over wire d at the same time as relay F is energized. The key K may be replaced by contacts on either the buttons PB or the switch hook SH.
