A moulded plastics crate for bottles comprises continuous upper and lower frames 1, 4 connected by support walls 5 spaced inwardly from the corners of the crate and each having an inwardly directed reinforcing rib 6, integral partition walls 2, 3 spacing the bottles. Below the partitions a cross-lattice (20, 21), Fig. 3 (not shown), supports the bottles, and includes diagonal reinforcing ribs (23, 24) at each corner. The tops 7 of the ribs 6, Fig. 4, which decrease in thickness towards the top of the crate, stop short of the crate rim, so as to act as nesting projections. To facilitate stacking one crate on top of another, projections at the corners of the top rim are engaged in holes (16), Fig. 3 (not shown), in the corners of the bottom rim 10 of a crate above. To facilitate stacking of the crate on its side upon another like crate, sloped studs 26, Fig. 4, along the upper edges of the side support walls 5 are provided. The studs 26 of one crate are engaged between the rims 11, 12 at the edges of the upper frame 1 of the adjacent crate, their ends 27 locking in recesses 28 in the rim 11 of the adjacent crate. Triangularly-shaped projections 26 on the support walls 5 at the short ends of the crate provide sloping faces which contact adjacent faces of other crates during stacking, and act as guide surfaces. Projections (25), Fig. 3 (not shown), below the lower rim 14 of the lower frame 4, act as feet supporting the crate. The projections (25) are in line with the support walls 5, so that when one crate is stacked on top of another like crate, the weight of the top crate is transferred directly on to the top of the support walls 5 of the crate below.

Abstract: 1,142,841. Drilling machine details. KABELUND METALWERKE GUTEHOFPNUNGSHUTTE A.G. 10 May, 1966, No. 39499/64. Heading B3C. [Also in Division H1] A waveguide is made by laying a tube of metal or plastic material and finishing the bore of the tube in situ by means of a remotely-controlled, travelling milling-tool. The tool consists of a tubular body 1 having two sets of radially adjustable clamps 2 which engage the inside of the bore. The clamps are driven by electric motors controlled by two sets of three heat or light-sensitive elements (e.g. photo-electric cells). The elements of each set are grouped symmetrically around the axis of the device and the two sets are arranged in transverse planes at opposite ends of the device. The elements respond to an axial light or laser beam and cause the clamps to be driven to a position in which all six elements are equally illuminated by the beam. After this setting-up, the coarse and fine milling wheels 4, 3 are traversed from one end of the device to the other by means of a lead screw 8. The milling wheels are driven by means of a sun-and-planet gear (6, 7, Fig. 2, not shown). The device is then moved to another position by means of a cable and the setting-up and milling operations repeated. It is stated that a theodolite may be used for setting- up in place of the above-described arrangement.

Filed: 1961-11-09
Abstract: 977,265. Disc brakes. AUTOMATIC PRODUCTS CO. Ltd. Oct. 24, 1962 [Nov. 9, 1961], No. 40209/61. Heading F2E. A disc brake comprises a pair of arms 10, 18 extending along opposite sides of a disc (not shown) and carrying pads 5, 6 for engagement with opposite faces of the disc, a pivotal mounting 11 for the arm 10, a support for the adjacent end of arm 18 consisting of a ball 23 engaging a V-shaped slot 20 in the arm and a conical recess 21 in a fixed support pin 22, a link 13 interconnecting the opposite ends of the two arms, a fixed fluid pressure cylinder 30 whose piston 29 acts through a push-rod 28 on the arm 18, and an alternative brakeapplying means comprising a lever 26 carried on a fixed pivot 27 and havin gone end in engagement with a pin 25 carried by the arm 18. The lever 26 is connected at 19 to a handbrake linkage. The pads 5, 6 are carried by backing plates 7 which are pivotally mounted at 8 on the respective arms. Link 13 is adjustable in length by a screw 16 the end of which engages a recess 17 in the arm 18. The arms are urged apart to a brake releasing position by a torsion spring (Fig. 2, not shown) having arms engaging the pivots 8. A bolt 35 is adjustably mounted on a fixed part to limit movement of arm 18 away from the disc and hence minimize chatter squeal. A compression spring 24 is located between recesses in the respective arms so that ball 23 is pressed into the slot 20 and the conical recess 22. When the brake is applied by operation of lever 26 or actuation of cylinder 30 the drag force acting on pad 5 causes camming action of the ball in the slot 20 and recess 21 so as to cause additional braking force to be applied by self-servo action.

Title: Improvements relating to electronic apparatus
IPC: G06G7/184
Filed: 1968-08-22
Abstract: 1,270,393. Averaging circuits. MOLINS MACHINE CO. Ltd., and R. C. BOLT. 21 Aug., 1969 [22 Aug., 1968], No. 40309/68. Heading G4G. [Also in Division G1] An analogue signal is divided into positive and negative portions which are chopped to form trains of pulses, the pulses being integrated over a given time period and the integrals compared to a signal representing the average of the analogue input. The first positive pulse, of amplitude P1 of a train of such pulses, charges both capacitors so that the voltage appearing at point J is kP1 where k is the ratio of the capacitance of FC to the sum of both capacitances. The amplifier A gives an inverted output which in this case is a negative pulse blocked by the diode D. At the termination of the pulse, the voltage at J starts to fall and the amplifier receives a negative-going input. The resulting positive-going output is fed through the diode D to junction J and tends to oppose the fall in voltage at this point which remains substantially equal to kP1. Subsequent pulses add increments kP2, kP3 ... kP n  to the voltage at J. If the capacitance of SC is (n-1) times that of FC, k = 1/n and the voltage at point J is 1/n (P1 + P2 + ... P n ) i.e. the average value of the pulse amplitudes. In the integrator of Fig. 2, the input signal fed through resistance IR is a continuously varying voltage representing e.g. mass per unit length of a cigarette rod passing a detector head. The signal is amplified by inverting amplifier Al and sorted into positive and negative portions by diodes DP, DN. Adjustment of feedback resistors FRP, FRN enables the amplifications of the two portions to be equalized. Both portions are sampled by a chopper CS operating at a fixed frequency and the resultant positive and negative pulses fed respectively to pulse adders PPA, NPA of the Fig. 1 type. The sets of pulses are added over a period determined by a switch SS which may e.g. operate in synchronism with the rod cutter in the cigarette-making machine. The switch discharges the pulse adders PPA, NPA and their outputs are fed to a difference amplifier A2. The amplitude of the output pulse of the amplifier A2 provides an indication of the amount by which an individual cigarette is within, or exceeds, a given weight tolerance. The switch RS operates in synchronism with the switch SS and serves to re-set the storage capacitors in the pulse adders PPA, PPN.
